Omega-3s found to help those suffering from PTSD
May 06, 2019 03:18 PM
New Japanese research suggests that omega-3 fatty acids may help mitigate one of the major psychophysiological symptoms of PTSD: a racing, pounding heart. The researchers divided over 80 survivors of major accidents into a control group and a group that received supplementary omega-3s. The omega-3 group had lower resting heart rates and also lower heart rates after being subjected to imagery related to their accidents. Omega-3s play an important role in brain health and neurological functions, and have already displayed potential utility in the treatment of depression.

Hesperidin, a natural flavonoid in citrus fruit, found to prevent photoaging
August 01, 2018 05:53 PM
A recent study has revealed a new treatment for skin exposure to UVB rays. Hesperidin is a compound found in many common citrus fruits, like oranges, and has more health benefits besides helping with the impacts of UVB rays. According to the paper, hesperidin also has impacts on wrinkles, aging, and inflammation of the skin. All of these benefits were confirmed through initial testing on mice. Scientists are hopeful for the future of hesperidin in skincare and treatment.
"Results showed that mice that were treated with hesperidin had improved length and depth of wrinkles, as well as inhibited the development of skin thickness and epidermal hypertrophy."

Scientists study the neuroprotective effects of fermented Curcuma longa L. (turmeric)
July 04, 2018 05:54 PM
A recent Kristina University study suggests that fermented turmeric may help protect brain cells from being degraded by inflammation and oxidative stress. The same researchers found that fermented turmeric may also help protect against the impact of the amnesiac compound scopolamine. Researchers subjected scopolamine-treated mice to mazes and inflicted oxidative stress on rat brain cells to test whether fermented turmeric offered any protection. Preliminary results suggest that fermented turmeric could have value as an alternative or complementary treatment for neurodegenerative diseases symptoms.
"It could serve as an alternative or complementary therapy for age-induced neurodegenerative diseases like Alzheimer’s disease."

EastEnders star Pam St Clement reveals she's turned to cannabis to fix her joints after being left in ...
December 06, 2017 03:59 PM
Legalizing cannabis is at the forefront of many media outlets today. Some celebrities like Pam St. Clement are stepping up and confessing their use of cannabis to help relieve the ailments they suffer from such as the polymalgia rheumatica that Pam has.
She uses CBD which is an oil derived from cannabis that does not make you high. A drop or two under her tongue daily gives her the relief she needs in her joints to be able to function in a more normal way that she has not enjoyed in years.
It could be very helpful to the legalize cannabis movement when stars stand up and promote the drug as a legitimate way to help with many ailments and diseases without resorting to other drugs such as steroids,
"Pam, 75, stunned TV viewers last month by smoking cannabis with nuns and getting high on a bong while filming Gone To Pot: An American Road Trip ."

Scientists stunned to learn that gut bacteria seem to have control over your moods and brain function
July 13, 2017 12:14 PM
A team of researchers from the University of California, Los Angeles have found a link between their female subjects' gut bacteria and higher levels of anxiety, irritability, and distress. Subjects whose fecal matter contained the bacteria strain Prevotella displayed an increased number of neural connections linked to emotional, attention, and sensory brain regions. The findings of this study may help explain why individuals with irritable bowel syndrome and functional bowel problems are more prone to developing depression and anxiety.
"This is the first time that behavioral and neurobiological differences associated with microbial composition have been studied in this way."

Animal Study Finds Monounsaturated Fats in Olive Oil May Extend Life
June 10, 2017 12:14 PM
A recent genetic study on metabolic changes has discovered an unexpected finding: accumulation of monounsaturated fats may lengthen one's lifespan. Though the study was conducted among roundworms rather than humans, it is interesting to note since researchers previously thought that decreased caloric intake would increase longevity. Rather, it appears that this particular build-up of fat and calories can be beneficial. The researchers discovered this by blocking certain DNA-modifying proteins to increase lifespan among worms, and then noted that these worms displayed higher levels of monounsaturated fatty acids.
"Prior research shows the type of fat consumed has a much greater influence on health than the quantity, and the recent experiment builds upon what is known on the topic."

Why marijuana became illegal
April 26, 2017 11:59 AM
Marijuana became illegal largely through the efforts of a businessman named William Randolph Hearst. Hearst operated in the paper industry and faced potential competition through the hemp industry. In order to stave off competition, he began campaigning to make marijuana illegal. His campaign involved lies and deceptions and played on primitive emotions such as racism and nationalism. The effort was extended by those in government and the medical industry. The experts who helped pass the anti-marijuana laws used similar tactics and had financial interests in the outcome of the legislation.
"For thousands of years, all good quality paints and varnishes were made from hempseed/linseed oil. After 1937, they were replaced with synthetic petrochemical oils made mainly by DuPont."

Lutein and brain health: Enriched formula leads to selective increases in multiple brain regions
January 31, 2017 12:59 PM
Lutein has been tested in more primates than humans and its link to brain and ocular health is fairly significant. Scientists have noted an increased need in lutein among babies- in utero and also after they are born. Lutein can be added to and consumed in infant formula. Lutein is a strong antioxidant and can be very useful for developing babies.
"All of the brain regions examined – the prefrontal cortex, the occipital cortex, the superior temporal cortex, the striatum, the cerebellum, and the hippocampus – all displayed selective increases in lutein deposition, with the highest amounts in the occipital cortex."
Doctored marijuana gives relief to boy
January 17, 2017 07:59 AM
Many anti-marijuana advocates state that the drug is harmful. There are thousands, if not millions, of people who claim that it can help give relief to those with chronic conditions. It’s easy to state that, but what about a real-life case to back it up? Think about Jackson Leyden, who started having several seizures a day at the age of 8. He has tried almost all seizure therapies out there and nothing worked. Within just a few days of starting THC extract therapy, he had barely any seizures. He went from having 200 a month to about two per month.
"The strain of marijuana that Jackson takes is unusual: It contains high levels of cannabidiol, or CBD, one of the two main molecules in marijuana; the other is tetrahydrocannabinol, or THC. While THC is famously mind-altering, CBD is not."
Orange peel is effective for treating asthma-Expert
December 03, 2016 08:59 AM
The usefulness of oranges has been seriously underplayed. We usually eat the inside of the orange and discard the peel, but this tart covering may be even healthier than the pulp. A community health expert in Nigeria is urging residents to keep the peels from oranges. She says they are abundant in vitamins, minerals, pectins, and fibers that are great for our bodies. The amount of fiber is said to lower weight since it is also low in calories. It is also thought to help with bronchitis and asthma due to its histamine content.
"People dislike orange peel because of its bitter taste but this peel acts as an excellent weight loss aid, as it contains good amount of fibre and is low in calories."
Soy should not be consumed in significant quantities unless it has been fermented or otherwise traditionally processed; industrially processed soy should be avoided
November 01, 2016 09:04 AM
Are dairy products hard for you to tolerate? Have you ever tried using soy products? Do you know of the different things that you should be aware of with Soy? If you said yes to either of the first two questions then you should take a look at this article about how soy should and should not be consumed.
"What many debates over the nature of soy fail to take into account is that soy-based foods are neither healthy nor unhealthy; it all depends on the processing."
Superoxide Dismutase (SOD) and its Protection of the Liver
September 27, 2015 08:37 AM
SOD consists of enzymes that speed up the break-down or partition/dismutation of the superoxide (O2-) radical into its constituent molecular content Oxygen or hydrogen peroxide. Superoxide is harmful to cells and is produced as a by-product of oxygen metabolism; therefore it needs to be controlled or regulated. The resultant Hydrogen peroxide is also harmful but to a less extent, and it is further broken down by other enzymes like catalase, This sums up the crucial role played by Superoxide Dismutases (SOD) as an important antioxidant in almost all living organism exposed to oxygen.
SOD extracted or laboratory manufactured can be used as a medicine orally or taken as an injection. When taken orally it is believed to remove wrinkles, rebuilding tissue, and prolonging life; even though it is not proven that orally administered SOD is absorbed by the body. When injected it functions as a painkiller, treatment of inflammation caused by sports injuries, osteoarthritis, kidney condition known as interstitial cystitis, gout, cancer, lung problems in infants among others.
A critical role played by SOD IS the protection of the Liver; which is one of the most crucial organ in the body for it is engaged in high-level metabolism in its function of detoxifying chemicals, breakdown of drugs and conversion of certain food into necessary nutrients for the body. These processes entail the high use of oxygen needed by the liver cells in the effort to function optimally and thus the production of the harmful Superoxide as a by-product. SOD as an enzyme helps to break down this harmful by-product that is potentially harmful to the liver cells and consequently prevent tissue damage.
SOD also prevents oxidative tissue damage of the liver as the result of strenuous exercise. Exhausting exercise or running causes a significant surge in the activities of glutathione peroxidase (GPX), and xanthine oxidase (XO), and in addition to increased levels of thiobarbituric acid-reactive substances (TBARS) in liver tissue immediately after the activity. Scientific studies have revealed that effective protection of the liver against such oxidative damages requires increased dosage of the antioxidant SOD.
Educative And Informative Details About NADH Supplement And Its Benefits
May 12, 2014 03:34 AM
What is a NADH
Nicotinamide Adenine Dinucleotide (NADH) is an activated form of B vitamin niacinin, which is available naturally in the body, from poultry, meat, fish and in minimal quantities from vegetables and fruits. This substance is also commonly referred to as the most important coenzyme mainly because of the import role of transforming food-based energy into energy, which can be utilized by the body cells. Due to the roles played by NADH, it has been developed into supplements, which have various benefits. NADH role in the body is important since the body cannot utilize the energy inform of whole proteins, carbohydrates and fats which are the main sources of energy.
How NADH works
Instead, when the foods that provide the body with energy are ingested, they are usually broken down into smaller parts after being absorbed and distributed into various cells. One of the things that are derived after these foods being broken down is acetyl, which is a two-carbon molecule. Enzymes are the primary components that break the foods into acetyl. However, enzymes require coenzymes to break these foods properly and extract the energy from acetyl. This makes NADH is an important coenzyme, which extracts energy from reactions between oxygen and acetyl. This coenzyme also helps in transforming tyrosine, which is an amino acid into dopamine, which is a brain chemical.
Benefits of NADH
One of the primary benefits of NADH supplement is that the brain chemical it helps to produce known as dopamine helps in improving various brain functions. Some of these functions which this chemical affects include; concentration, mood, muscle movement, sexual drive and energy. It also helps in athletic performance, slowing aging process, Parkinson's disease, depression and Alzheimer's disease.
This supplement is also helpful on people with chronic fatigue syndrome. This is achieved through helping patients reduce anxiety and reduce heart rate. Consequently, the patient is able to relax and allow the body to function normally. Therefore, NADH supplement is helpful and has many benefits if it is used properly.
Grape Seed Extract
November 13, 2012 07:58 AM
Grape seed extract ( also known as vitis viniferal) is a substance derived or sourced by manufacturers and industries from whole grape seeds. Grape seed extract was discovered in the Ancient Greece and many parts or sections of the grape were commonly used for different medicinal purposes.
Grape seeds have a high concentration of Vitamin E, linoleic acid, Flavonoids and Opcs. Its health benefits. Its said to help protect the body against cancer. Studies done by scientists in laboratories have demonstrated that grape seed can actually help fight and protect against the free Radicals attacks in the body ( Radical attacks are Chemical by products which are known to lead or cause damage to the DNA of the body thus leading to cancer).
Grapeseed extract and Diabetes
According to a 2009 study on 32 type 2 diabetic subjects at high cardiovascular risk, it was seen that extract played a significant therapeutic role or part in decreasing cardiovascular risks.The grape seed extract greatly improved the markers of glycemia and inflammation which showed that the grape seed extract helped in decreasing cardiovascular risks in the type 2 diabetic patients.It is also known to help in eye diseases related to diabetes.
Still in 2009, a study done on patients with a Metabolic syndrome revealed that the extract significantly lowered the chances of having type 2 diabetes and developing a heart disease. It can also help in a type of poor circulation called 'chronic venous insufficiency'. In addition it helps in high cholesterol conditions, it reduces swelling caused in injuries. The primary cause for aging is 'oxidative stress' which is normally caused by free Radical attacks (Mentioned earlier).
To protect against Oxidation the body needs Vitamin E and C, the extract contains a high concentration of Vitamin E which helps curb oxidation. Grape seed extract (as noted earlier) also helps in fighting the free Radicals that cause oxidation thus slowing down the aging process.
The Tremendous Health Benefits Of Omega- 3 Fatty Acids
November 10, 2012 11:53 AM
Omega-3 vs Omega-6
Several sources of information and clinical studies have revealed that the ratio between these two essential fatty acids in our diet have over a period of time played a significant role in making humans prone to certain diseases that the early humans were not afflicted with.
The raging debate in finding the right ratio arises also from the fact that modern foods preferences lean heavily toward the consumption of omega-6 rich foods . This fatty acid has been linked to the pathogenesis of cardiovascular diseases, cancers, inflammatory diseases, immunodeficiency, artherosclerosis, hypertension, blood pressure, arthritis, diabetes and obesity. In the last ten thousand years our genetic structure has remained the same, but with the onset of the Agricultural Revolution radical changes in food habits have created a lopsided diet. The western diet is heavily oversubscribing to the use of the polyunsaturated fatty acids or PUFA, and going low on Essential Fatty Acids or EFA. Living in the industrial societies that we do and in a kind of nutritional environment that we live in, we need to make informed choices about the food we consume is important considering how high- risk western societies are to many kinds of ailments.
Both omega-3 and omega -6 fatty acids are essential for us, but have to be obtained from food as the human body does not have the ability to produce it. Clinical evidence has shown that the Mediterranean diet is more focused on fresh fruits, vegetables, fats from olives, fish, nuts, garlic and whole grains. It has the requisite amounts of healthy fats to combat numerous diseases like coronary condition, rheumatoid arthritis, depression, high cholesterol, schizophrenia, inflammatory bowel disease, asthma, bipolar disorder and colon cancer. Astounding also is the finding that our body possesses a certain enzyme that can be linked in its structure and function to these essential fatty acids. These are called prostaglandins.
Prostaglandins are the end products of a chain reaction that begins with the release of unsaturated fatty acids from the cell membrane. It was first isolated from human semen and has found great use as an enzyme based treatment for menstrual problems, childbirth and many other medical conditions. Its ability to increase blood flow has resulted in its use for inducing abortion in troubled pregnancies. However, its over secretion in the body is related to numerous inflammatory conditions and has been found to increase in the body due to the overbearing presence of 0mega-6 fatty acids.These facts can not be taken lightly for a civilization reeling under the onslaught of devastating ailments. Its time to take heed .
Why Should I be Using a Natural Mouth Wash?
March 18, 2011 04:51 PM
Natural Mouth Wash, Should you Switch?
Natural mouth washes have been around since time immemorial. Earliest accounts point to their use in treatment of gingivitis, but only recently have they played an important role in oral hygiene. The discovery of antiseptic compounds, such as chlorhexidine, has brought mouth washes into mainstream popularity. Their commercial value remains strong although new studies seem to favor the use of natural mouth washes.
Provides Excellent Antiseptic Properties
Salt solution is among the earliest of all natural mouth washes. It is easy to prepare and proven to aid against mouth infections. In Greek and Roman antiquity, physicians recommended a mixture of salt and vinegar, which does kill certain microorganisms in the mouth cavity known to cause dental carries. This has also been used in Ayurvedic and Chinese Medicine in allaying mouth pains and promoting periodontal health.
The ancient text of Jews, the Talmud, records the use of olive oil for gum problems. Today plant-based oils are widely accepted to display excellent antiseptic properties, and there is scientific consensus that most essential oils are potent enough to denature pathogenic microorganisms. Aloe vera, cinnamon, fennel, tea tree, myrrh, and peppermint are becoming increasingly popular as ingredients for natural mouth washes largely owing to their desirable scents in addition to being potent bactericides.
Avoids Bad Effects of Synthetic Compounds
The appeal of natural mouth washes lies in the absence of chemical compounds suspected to be harmful to the oral mucosa and the entire mouth cavity. Parabens are a group of chemicals that are commonplace in the cosmetic industry. Among all chemicals present in mouth washes, they are the most controversial in that studies have associated them to carcinogenic effects and estrogenic properties.
It is a well-established fact that sodium lauryl sulfate, or SLS, a chemical derived from lauryl alcohol and sulfate trioxide, is an irritant whether consumed or topically applied to body surfaces. Moreover, their presence in toothpastes and mouth washes has been linked to higher incidence of aphthous ulcers, or what we refer to as canker sores. Natural mouth washes do not contain SLS, but are known to mimic the antimicrobial properties of SLS to teeth and gums.
Synthetic dyes have long been recognized as irritants to the endothelium that line the mouth, and a few are known carcinogens in animals. Triclosan, an antifungal and antimicrobial agent widely used in many types of disinfectants, is now tied to disturbances in the endocrine system. Natural mouth washes are products that can be replicated at home, with the use of ingredients that are all-natural and at the same time devoid of identified irritants.
Relieves Inflammatory Oral Problems
Natural mouth washes are just as effective as those that contain compounds derived from reactions of organic compounds. In the past few decades synthetic compounds have been commercially touted to be effective against inflammation, but there is also a resurgence of interest in naturally occurring compounds, which are equally helpful in inhibiting inflammatory mediators present in the mouth.
If you are using a commercial mouth wash, changing to a natural mouth wash can free you from consuming chemicals that might cause cancer.
Do the switch today!

Hoodia Gordonii is a South African succulent plant of the family Apocynaceae. They are remarkable similar in appearance to cacti, although they are totally unrelated to them and grow predominantly in the region of Central Namibia in the south west of Africa, up to the southern regions of Angola. They are most commonly found in rocky ground and on the plains.
There are several species of hoodia, some of them grown domestically, and it is Hoodia gordonii that is used as an appetite suppressant in hoodia weight loss pills. Although the plant has historically found use in the treatment of infections and gastric problems, most interest is displayed in its use by the bushmen of the Kalahari Desert to suppress their appetite during long hunting trips when food and water are scarce.
The active ingredient was isolated in 1977, and given the name P57: the product is therefore often referred to as Hoodia P57. It was patented by its discoverers, the CSIR (South African Council for Scientific and Industrial Research) and a license granted to UK company Phytopram, who worked together with Pfizer to isolate the active ingredients and manufacture them synthetically. This was found to be very difficult, if not impossible, since any synthetic form of the extract failed to display any hunger-suppressant properties.
Finally, the rights to the main ingredient were released by Pfizer in 2002, thus indicating that it was of no commercial benefit to them. The main problem they admitted with synthesizing P57 was not only the difficulty in doing so, but also that there were side effects of the extract on the liver caused by other components that could not be removed. No synthetic form of hoodia is therefore available, and only the natural plant is used in current Hoodia 57 preparations.
The rights of the San Bushmen to the plant were recognized by the CSIR in 2002, and not only do they receive a proportion of the profits of marketing hoodia, but also the plant is protected with wild-harvesting licenses provided to only certain individuals and companies. Due to the rising popularity of the hoodia weight loss industry, the plant has been named as an endangered species in the wild.
It is believed that the active ingredients are steroidal saponins that can fool the body into believing it is full. This theory is based upon the effect on appetite of glucose concentrations in the blood. Your appetite is controlled by the amount of unconverted glucose in your blood, and glycogen in the liver. When you eat carbohydrates, they are digested and converted into glucose which is absorbed into the bloodstream.
Under normal conditions your blood glucose levels increase to a level where a signal from hypothalamus stops you feeling hungry. Insulin is then secreted from the pancreas to prepare your cells to use that glucose in the mitochondria to create energy by means of the Kreb's Cycle, or Citric Acid Cycle as it is also known. This reduces the concentration of glucose in the blood, and once it reaches a certain level the body begins to use its emergency energy supply, glycogen, that is stored in the liver.
A signal then informs the brain that more glucose is needed. You then feel hungry again, and this cycle is repeated several times a day in a normally healthy person. This cycle is controlled by certain hormones in the brain, specifically in the ventromedial center of the hypothalamus, where it is believed that the ATP (adenosine triphosphate) availability controls the release of the hormones involved.
ATP is the molecule of energy, and as the concentration of blood glucose and of glycogen drop, then the amount of ATP produced also drops and this is detected in the hypothalamus, which reacts by releasing ghrelin. Increased leptin increases the feeling of satiety and ghrelin increases the feeling of hunger. Serotonin acts on the brain to increase the effect of leptin in the hypothalamus, and therefore make us feel less hungry, or more satiated.
It is believed that hoodia gordonii, or the Hoodia P57 component of it, fools the brain into believing that your blood glucose or glycogen levels have reached the point at which it should trigger a satiated response, so that you stop eating even though your ATP levels might be low. The steroidal saponins that it contains is believed to be ten thousand times more effective than glucose in stimulated the secretion of serotonin.
Hoodia has also been found to contain a number of glycosides, including pregnane glycosides that some studies have indicated to help control appetite of the subjects tested. Most of these tests have been carried out on animals, although Hoodia weight loss preparations are offered in a form standardized on both steroidal saponins and pregnane glycosides.
Hoodia gordonii is becoming so popular as a weight loss product that its export is being monitored by the South African government. It has become so endangered that, since 2005, only hoodia grown on commercial farms is permitted an export license, and exporters must obtain a license from the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Importers also require a permit from the US department of Agriculture, and a CITES certificate is also needed to re-export the finished product.
Because of this, more hoodia weight loss pills are being sold than there is hoodia gordonii to produce them. It is not uncommon for cacti such as the prickly pear cactus from Mexico, to be used, or for low concentrations of hoodia to be bulked up with fillers. Neither of these is of any use as an appetite suppressant, the former having no active ingredients whatsoever and the latter containing only traces.
If you are purchasing hoodia, therefore, be aware of this. Request sight of the CITES certificate and USDA permit, and also the analysis results by an authorized laboratory to confirm that the product is what it purports to be. Otherwise, there is some evidence that Hoodia gordonii can help you reduce weight, although to date there are only four recognized analytical laboratories registered to analyze the active content of hoodia weight loss products.
Finally, check for the analysis certificates. All Hoodia weight loss products should be analyzed by each of three methods: Microscopy, High Performance Thin Layer Chromatography (HPTLC) and High Performance Liquid Chromatography (HPLC) - all there are needed. The four authorized laboratories are: the University of Mississippi, Chromadex labs in Irvine California, Alkemist Pharmaceuticals and Advanced Laboratories, Smithfield, NC.
No others will do, so if your Hoodia weight loss preparation has not been analyzed using the three methods by one of these laboratories, don't buy it, even if it can show the CITES and USDA documentation.
Horny Goat Weed
December 06, 2008 10:05 AM
Horny Goat weed, correctly named Epimedium, or Yin Yang Huo in Chinese, is one of over 60 herbaceous plants of the Berberdaceae family. It grows naturally in Southern China, and also in Korea, Southeast Asia and some parts of Europe. Other names given to include Fairy Wings and Bishop's Hat.
Horny goat weed has been viewed as a natural alternative to Viagra, and many species of Epimedium are said to possess aphrodisiac properties, and is said to have got its name from a Chinese goat herder who notice that his goats became more 'frisky' with the lady goats after eating the plant. In fact studies have indicated to increase vitality, particularly the libido and male sexual vitality, although it also possesses some other health benefits in its effect on dementia and osteoporosis.
The term 'horny' is used in the colloquial sense, and has nothing to do with the shape of the plant, the flowers of which are star-shaped. In fact the Chinese name for it means 'licentious goat weed', making the English translation quite clear.
The main ingredient in horney goat weed is icariin, a flavonoid glycoside that acts as a PDE5 inhibitor. Others include the similarly named, but totally different chemical, icaritin, and also many other that will be discussed later. It is icariin on which we shall focus for the time being. Since this is central to its effect on erectile dysfunction, some time will be spent on explaining what PDE5 inhibitors do.
cGMP (Cyclic guanosine monophosphate) is a chemical that relaxes smooth muscle tissue, including the vascular smooth muscles in blood vessels. This can lead to the dilation, or increase in size, of blood vessels and increased blood flow. The corpus cavernosum of the penis is a spongy area that runs the full length of the penis, and contains many blood vessels that can be dilated through the action of cGMP and allow the increased blood flow to create an erection.
PDE5 (phosphodiesterase type 5) is an enzyme that can degrade cGMP and prevent the relaxation of these blood vessels, and so prevent them from dilating. A PDE5 inhibitor, such as icariin, prevents the PDE5 from degrading cGMP, and so allow a normal erection. Sidenafil, commonly known as Viagra, is a similar PDE5 inhibitor and works in the same way as icariin. Hence, the effect of Viagra is not to create an unnatural erection, but in fact to allow the cGMP to do its natural work by preventing the phosphodiesterase from stopping it doing so.
This is just one of the effects of horny goat weed: it is a more natural PDE5 inhibitor than Viagra is. It is also more specific than Sidenfil, and does not interfere with any of the other phosphodiesterases that are essential for other purposes. However, its effects do not stop there, because icariin possesses other properties, and is also only one of the many components of epimedium that can increase vitality.
Among these are a number of flavonoids in addition to icariin, sterols and the isoquinoline alkaloid magnaflorine, that possesses antioxidant properties and reduces LDL cholesterol. The exact mechanism by which horny goat weed works to increase sexual desire is unknown, but it is believed that it inhibits the enzyme acetylcholinetsrase (AChE). Cholinergic synapses are the spaces between brain cells that allow electrical impulses to be transmitted, and are an essential component of neuromuscular system response to stimulation.
AChE can stop these from working properly, and prevent neurotransmitters from effectively allowing sexual arousal. Horny goat weed can inhibit the activity of this enzyme and allow the neurotransmitters such as serotonin, dopamine and norepinephrine to do their proper job in allowing sexual arousal to occur. This, again, is a natural and not a chemical solution. It has also been found to reduce cortisol levels that cause stress which also reduces sexual desire.
The effect of Epimedium on smooth muscles can also aid those suffering from pulmonary hypertension, in which the small blood vessels in the lungs become too narrow to be effective in allowing the transfer between oxygen and carbon dioxide. PDE5 inhibitors can help these blood vessels to relax and so be more easily dilated in the same way as those in the corpus cavernosum. Once dilated, they are able to carry more blood to and from the lungs and allow the reoxygenation process to continue smoothly.
Research has also discovered the possibility of horny goat weed possessing monoamine-oxidase inhibition properties. Monoamine oxidase enzymes can deaminate hormones such as dopamine, and can significantly reduce the production of testosterone. The inhibitor prevents this happening, and leads to elevated levels of dopamine, and also of serotonin and noradrenaline. Dopamine encourages the pituitary gland to release luteinizing hormone that in turn promotes the production of testosterone by the testes.
Another property of horny goat weed is that it can protect against the toxin beta-Amyloid, a protein that damages DNA in the brain, causing the death of brain cells and the accumulation of dead cells in your brain. This in turn leads to dementia and potentially Alzheimer's disease. The use of Horny goat weed is being studied closely in relation to this property. The active ingredient here is icaritin (not to be confused with icariin)
Epimedium also has implications in the treatment of the cartilage and bone damage that occurs with arthritis and osteoporosis. It is possible that this is connected with the antioxidant and anti-inflammatory properties of magnaflorine, and icariin has been found to have bone-healing properties. It is known that damaged cartilage treated with horney goat weed displayed signs of growth and regeneration when compared to a placebo.
However, the most popular use of horny goat weed is in its effect on the libido and erectile dysfunction. The effect on the libido and sexual desire works equally well for men and women, and it is a preferred natural remedy to synthetic equivalents such as Viagra, Levitra and Cialis. The added benefits of the natural product render epimedium the preferred and safest solution for many people.
Green Tea Extract
October 23, 2008 01:43 PM
Green tea is a form of tea made from the leaves of the Carmellia Sinensis, a shrub that is native to China and has spread to other areas of Asia including Japan and the Middle East. Drinking it is believed to impart many health benefits, including the prevention of obesity, heart disease and some forms of cancer and it has been used in traditional Chinese medicine for over 400 years.
Tea is known to have been consumed in China for around 5,000 years, and used, not only in Chinese medicine, but also in that of Japan, Thailand and India for a number of ailments including regulating blood sugar, treating wounds and digestive problems. The drinking of green tea to benefit the heart and other vital organs is described in the Kissa Yojoki (Book of Tea), written in 1191 by Eisai, a Japanese Zen priest.
This two-part book talks about the various medicinal benefits of green tea, such as preventing fatigue, curing beriberi, quenching thirst, clearing the thoughts, maintaining health of the urinary tract and improving digestive problems. It also explains how to grow tea and how to prepare and use the leaves. The methods of treatment of various ailments and medical conditions are described in the second part of the book.
The active ingredients in green tea are catechins, polyphenols with strong anti-oxidant properties. Antioxidants are important components of your diet due to their effect on free radicals. These are small molecules, generally oxygenated, such the superoxide cation and hydrogen peroxide that are generated during normal metabolic processes and also ingested in pollutants such as traffic and factory fumes and insecticides. Free radicals are also formed by the effect of the ultra-violet component of sunlight on your skin and other tissues.
The effect of free radicals on your body can be devastating, and they not only destroy cell membranes but also oxidize such molecules as the low density lipids (LDL) that carry cholesterol around your bloodstream. This allows the LDLs to be absorbed by the white blood cells and then deposited as fatty plaques in the walls of your arteries. The end result is a thickening and hardening of the arteries that leads to a condition known as atherosclerosis, where the blood supply to the brain and heart muscle is restricted, which can in turn lead to strokes and heart disease.
Their effect on your cells is to cause cancer and premature aging, among others, and free radicals are also believed to play a part in conditions such as Alzheimer’s and Parkinson’s disease and also inflammatory diseases such as arthritis and diabetes. They can also cause damage to your DNA.
It is essential, therefore, that these free radicals are destroyed as quickly as they are generated, and that is what antioxidants do. You might be more familiar with the antioxidants Vitamins A, C and E, and phytochemicals such as flavonoids and carotenoids, but there are many substances available to you that are even more powerful such as the polyphenols found in green tea.
Epigallocatechin gallate (EGCG) is the most powerful of these with antioxidant properties at least twenty five times that of Vitamin E, and 100 times that of Vitamin C. EGCG comprises around 10-50% of the total catechin content of the tea and studies indicate that it likely helps to protect against DNA damage by free radicals, to protect against oxidation of LDL, provide protection against the damage of ultra-violet radiation and to protect you from the free radicals that are generated by smoking tobacco and general airborne pollution.
There are suggestions that the bioavailability of EGCG can be increased by consuming black pepper when drinking green tea, possibly due to the presence of piperine in the pepper. The piperine appears to retard the intestinal glucuronidation of EGCG and so allow more of it to be absorbed as opposed to excreted. So if you are using green tea for health reasons, spice up your food with a small amount of black pepper - that's all it needs. You don't have to smother your food in it! It should be stressed that these tests were carried out on animals, although the biochemistry involved is much the same.
The oxidation of fat by your metabolism to provide energy is a very important factor in weight control. If the contribution of the fats you ingest to the energy generated by your metabolism is low, then the fats can go on to be deposited in your body. This is not only unsightly, in that it can basically make you look 'fat', but is also dangerous to your health. Fat deposits around your midriff and round the major organs of your body can be extremely damaging and a severe risk to your health.
It has been shown by a recent study in the UK (Birmingham University) that those taking green tree extract displayed a 17% increase in fat oxidation over those given a placebo. Not only that, but the ratio of fat oxidation to the overall energy expenditure showed a similar differential between the study and the control group. This provides evidence of green tea extract being able to control your weight by burning fat, and also to improve the tolerance to glucose and sensitivity to insulin of healthy people.
Many other health claims have been made for green tea extract, although many of these have little, if any, scientific basis. Among these are the claims that it can treat multiple sclerosis and be used to treat cancer, although claims that it can prevent the destruction of cell membranes due to its oxidative effect are supported by the biochemistry, if not the medical proof. There are cases where theoretical biochemistry can explain many of the applications of ancient remedies without needing modern day studies to support it.
Some of the research supporting the green tea theories include:
1. In 2006, a study was announced that had followed over 40,500 Japanese men and women, aged between 40 and 79, that had no history of coronary heart disease, stroke or cancer starting in 1994. It was found that those who drank at least 5 cups of tea per day had a 16% lower risk of dying from any cause and a 26% less risk of dying from cardiovascular disease than those that drank less than one cup of tea each day. Since cardiovascular disease and cancer are the major causes of death world-wide, these are significant results.
2. Again in 2006, it was reported in the American Journal of Clinical Nutrition that studies indicated that a higher consumption of green tea was associated with a reduction in human mental impairment when compared to the average.
3. Yale University School of Medicine reported later that year that, in spite of smoking more than their western counterparts, Asians suffered lower rates of cancer and heart disease, and put that down to them drinking over 4 pints of green tea daily. It was the polyphenol content of green tea and its antioxidant effect that was proposed for this result, known commonly as the 'Asian paradox'. A specific reason given for this was the antioxidant effect preventing the oxidation of LDL cholesterol, and its subsequent deposition in the artery walls.
4. Another component of green tea is the amino acid L-Theanine that promotes relaxation, and it is believed that this could help to fight stress by inhibiting the excitation of cortical neurons.
There is a lot more evidence for the health benefits of green tea, and once again it appears that the ancients have been proved correct. Perhaps we should pay more attention to ancient remedies, although without the proper evidence much of it is ignored - for the time being at least. Green tea, however, has generally been accepted due to the research and studies carried out on ECGC (Epigallocatechin gallate) and in additional to the traditional form, is also available as a dietary supplement.

DHA is a fatty acid that is essential for many body processes and structures. Fatty acids are the building blocks that create lipids, which are important nutrients that make up 25 to 45 percent of total body energy for most of those who are living in industrialized countries. The majority of dietary fatty acids are made from dairy products, meat, margarine, and vegetable oils.
Lipids are important because they store and transport energy from one part of the body to another and they also insulate and mechanically protect certain parts of the body. Any fat that is eaten is converted by the body into fatty acids, where it is then burned for energy, stored, or synthesized into other acids which are called prostaglandins. Some fatty acids are also vital structural components of cell membranes. DHA is part of a special class of highly concentrated, long-chained, polyunsaturated fatty acids called omega-3 fatty acids. Omega-3 fatty acids are looked at as one of the most fundamental molecules in the structure and activity of the membranes of all cells. They have a huge influence on the production of cellular regulatory compounds which are known as eicosanoids. They also are highly specialized in their function in neurological tissues, especially the retina of the eye. It is also very likely that omega-3s have specific and beneficial effects on the heart muscle, while they also influence the production of substances that control immune responses.
Fatty acids are short-chained, medium-chained, or long chained. Short-chain fatty acids are water-soluble and absorbed directly from the intestine into the bloodstream. They are generally used for immediate energy and can be found most abundantly in dairy products. Long-chained fatty acids are more emphasized when it comes to health concerns as they are stored in cell membranes and have a huge affect on membrane protein function. Their behavior in tissue membrane is what makes them greatly influential in health.
Besides the length of the chain, fatty acids are also described by their saturation. Saturation means how many hydrogen atoms the fatty acid carries. Fatty acids that carry as many hydrogen atoms as they can are called saturated fatty acids, while those that lose a pair of hydrogen atoms become unsaturated. This loss of hydrogen atoms creates a double bond between the two carbon atoms on either side of the missing hydrogen atoms. Those fatty acids that have one double bond are called monounsaturated fatty acids, while those with two or more double bonds are called polyunsaturated fatty acids. Most omega-3 fatty acids are highly unsaturated and have five or more double bonds.
EPA and alpha-linolenic acid are most commonly found in plant sources. DHA and EPA are made in phytoplankton, which is consumed by fish, mollusks, and crustaceans. The above reason is why these two essential fatty acids are found mainly in the aquatic food chain. LNA and EPA cannot substitute for DHA in all metabolic functions, even though DHA and EPA are more able to cover for each other in certain metabolic functions. It has been found that LNA is less effective than EPA which is less effective than DHA in enriching tissues, meaning that food sources such as vegetables and seed oils are not as good of sources than sea foods or other foods that are enriched with DHA and EPA. DHA in itself provides most of the health benefits displayed in research, to take essential oils that contain no DHA would limit the health benefits discussed above and from other sources. Have you had your DHA today?
How Important Is It To Have Proper Digestion
July 09, 2008 11:46 AM
The part played by food in the health of your body is to furnish it with the nutrients needed for the biochemistry that keeps you alive. The digestive process breaks the food that you eat down into a form that can be absorbed by your bloodstream, and from there to your liver which is your body’s chemical plant. That is where most of the biochemical reactions of your body take place, such as the manufacture of bile needed to break down fats during digestion.
Most people do not take this into account when eating, and in today’s hectic world nourishment is the last thing on their minds, yet the one aspect of their lives that can provide them with the energy to carry on as they do. They eat to get rid of the feeling of hunger, and any old thing will do: a burger or a pizza, but rarely an orange or some cheese on wholegrain bread.
Poor eating habits lead to poor digestion, which in turn leads to poor extraction of the nutrients from what we do eat, and therefore malnutrition. Yes, malnutrition! It is possible to suffer from that even though you fill your belly every day. It’s not the filling that matters, it’s what does the filling and how well it is digested. Proper digestion is very important to every living creature on this planet. The first step in ensuring that have a proper digestion function is to assess the quality of the food that you eat:
a) What nutrients does your food contain, and
b) Have you sufficient of the proper enzymes needed to break it down so that these nutrients can be extracted?
Nourishing meals are just as easy to find and eat as junk foods, and it is just as easy to a breakfast containing a high protein and fat content as it is to eat a chocolate biscuit. A hard boiled egg with whole meal toast and yoghurt isn’t difficult to prepare for breakfast, and some tuna, or cheese and whole meal crackers make a nutritious lunch. These foods are easier to digest than the greasy high-fat foods that most people eat at lunchtime.
Proper digestion requires relaxation, and eating when stressed or in a hurry creates the wrong pH conditions in your stomach, with hydrochloric acid production being suppressed and the production enzymes by the liver inhibited. Enzymes are essential to your health, and are types of protein that enable most biochemical reactions to take place. Without the proper production of enzymes, your food will pass through your body largely unchanged, and this indigestion can not only give you stomach pains but also weaken you because the nutritional value of your food is not being realized.
You should take the time to eat, and not try to eat on the job: that is why so many high fliers end up with ulcers. Take time to chew, and mix your food with saliva which itself contains the enzymes amylase and lysozyme. Amylase breaks down starch into sugars, while lysozyme inhibits the growth of oral bacteria. The digestive system therefore begins in the mouth when you chew your food. The breakdown of food into smaller particles also produces more surface area from which the nutrients can be absorbed.
Enzymes are very important to proper digestion, and your diet should include enzyme-rich food such as tropical fruits (pineapple and bananas), honey, and many vegetables. Yoghurt and lacto-fermented foods are also rich in enzymes, and many cooked foods also contain enzymes. An enzyme supplement can also be taken to top-up what you eat, and make up for any enzyme deficiency in your diet. Processed foods are fairly empty of good nutritional value, particularly enzymes, which is why so many people are so overweight: their food is a nutritional desert and their body keeps craving for food that leads to eating binges.
For your food to be properly digested your stomach acid has to be at a certain pH. If you drink too much liquid when eating then the acid will be diluted, and you will not properly digest your food. A glass of water is fine but two or three pints of beer, or a gallon of fruit juice, will dilute the hydrochloric acid concentration in your stomach, and it will not be able to break down your food. Consequently, your digestive system loses much of the nutritional content of what you eat. Restrict heavy drinking of liquid to about two hours before and two hours after eating each meal for maximum efficiency. Many people find that they have to take not only vitamin and mineral supplements to replace those which are lost through inefficient digestion, but also other supplements such as enzymes and extra proteins.
When food is processed or cooked, the process destroys enzymes. Since the body stores only a limited supply of enzymes, eating well cooked or highly processed foods continuously, places great strains on the enzyme reserves, and ultimately the metabolic enzyme reserves have to be used in order to digest your food. This diverts them from their proper purpose, and many of the functions of your body are disrupted.
For example, your lose energy and your immune systems begins to weaken, making you feel tired and more susceptible to illness and disease. You should therefore try to eat foods rich in enzymes, or use an enzyme supplement. Natural raw foods are an excellent addition to your diet, and salads and fruit should be regular components of your meals. Obviously you must eat some cooked foods, but that does not mean that you should avoid eating fresh raw fruits and vegetables altogether. That is a recipe for a dietary disaster.
Enzymes are extremely important components of your digestive system, as is dietary fiber. In fact if you eat a diet containing dietary fiber, some raw fruit and vegetables, and protein, either cooked or uncooked, you will be giving your digestive system a boost. If you are unable to maintain that, then enzyme supplementation, together with general multi-vitamin and mineral supplement daily, should help you to maintain a healthy digestive system. However, fiber is essential since without it you will become constipated, especially if you consume a lot of pulpy foods that mainly consist of water.
It is extremely important that you have proper digestion of the food that you eat, and that your body makes the best use of the nutrients that it contains. To achieve this, you have to maintain the correct pH of stomach acid, and eat foods with the nutritional content required by the human body. This means not overcooking a balanced diet containing protein, fiber, enzymes and other nutrients such as vitamins, minerals and phytochemicals (plant-based chemicals).
L-Carnitine For Health And Wellness
April 16, 2008 03:25 PM
Research continues to mount evidence that l-carnitine can help boost energy and quality of life. Carnitine comes from the Latin word for flesh: caro or carnis. L-carnitine was discovered and isolated from meat in the early 1900s. At that time, scientists thought that l-carnitine played a role in muscle function; this was many years before technology would advance so that this theory could be proved. Today, we know that this amino acid is found mostly in tissue of the body that requires lots of energy such as the heart, skeletal muscles, and liver.
L-carnitine is considered a non-essential amino acid since the body manufactures it from l-methionine and l-lysine. Depending on one’s diet, the body manufactures most of, not all, the l-carnitine it needs every day. There are circumstances where a rare genetic disease can cause the body to not manufacture its own l-carnitine resulting in a deficiency which can cause secondary diseases such as cirrhosis of the liver, chronic renal failure, diabetes, heart failure or Alzheimer’s disease. Some medications can cause a deficiency as well, check with your doctor about prescriptions.
The primary energy source for the body is long-chain fatty acids. L-carnitine plays an essential role in energy production process. This amino acid transports long-chain fatty acids into the mitochondria, where it is used to produce energy for each cell in the body. l-carnitine then removes the “acyl” group by products out of the mitochondria as they accumulate. Both the transporting in and out of the cells mitochondria is vital for continued muscle function to occur.
Researchers suggest that the limiting factor in high intensity exercise is from the availability of l-carnitine in the muscle tissue. Studies conducted with this amino acid suggest that athletes experience improved performance when supplementing with l-carnitine by reducing post exercise lactate acid levels and improving recovery from exercise stress.
Some research suggests that l-carnitine can help chronic fatigue individuals by shuttling long-chain fatty acids into the mitochondria where the body manufactures energy. The bulk of this research was done on chronic fatigue patients who consumed 2 grams per day of l-carnitine. Additional research was performed on individuals over 100 years of age and the results were these individuals experiences increase physical endurance and improved cognitive activity.
L-carnitine can help cardiovascular conditions including angina, congestive heart failure, and peripheral artery disease. Recent studies showed male fertility improvement when l-carnitine was consumed on a regular basis. Men participating had better sperm motility which increases the changes of one reaching an egg and improving the odds of fertilization.
Research also demonstrated that 1 gram of this amino acid daily over three months can help one reduce weight by improving fat metabolism. This holds consistent with the findings that l-carnitine transports long-chain fatty acids (fat) into cellular mitochondria so it can be burned as energy. With a good diet and exercise plan, reports suggest that even more weight loss can be achieved.
Safety is of particular concern when adding extra supplements to one’s diet such as l-carnitine. Good news, l-carnitine is very safe at 1 – 3 grams each day, even higher doses are safe with no side effects. With the mounting evidence on the benefits of l-carnitine consumption, what is stopping you from adding l-carnitine today to your supplement diet to improve health and wellness?
Fight Osteoporosis With Minerals To Build Bones And Improve Quality Of Life
April 02, 2008 11:06 AM
Bone consists predominantly of collagen and calcium phosphate. The collagen provides the connective framework for bone that is hardened by the calcium phosphate, and without healthy bones, your quality of life would be significantly reduced due to bone breakage. That is why it is essential to supplement this framework with the vitamins and minerals needed to maintain a good bone density at those periods in your life when bone density is liable to deteriorate.
This begins to happen between the ages of 30 and 35 and in women and accelerates during the menopause, when your ovaries stop producing the hormone estrogen that is necessary for the maintenance of healthy bones. Through time, your bone mass drops creating first a condition known as osteopenia, or reduced bone mass, and then osteoporosis, when your bones become brittle, porous and very prone to fractures.
Before we look at what can be done to reduce your chances of developing osteoporosis, lets have a close look at how bone develop so that it will be easier to understand the remedial action that can be taken.
Calcium is the most common mineral in the body, and the vast majority is in the bones and teeth. Phosphorus is also essential for healthy bones because as stated earlier, the bone consists of collagen that is hardened by calcium phosphate. The two main uses of phosphorus are in bone structure and animal metabolism, since phosphates are also essential for the vast majority of the energy-production chemical reactions within your body.
Calcium has other functions within the body other than bone, however, including exchange of fluids within and between cells, the maintenance of your heartbeat and in blood clotting. Vitamin D is necessary to help calcium be absorbed from your diet, through the membranes of the duodenum. More calcium is absorbed there than in the small intestine, and the calcium is also most available to the body when it is in a water-soluble form.
In fact, the reason that stones form in your kidney for example, is that the calcium is rendered insoluble through the formation of calcium oxalate from the oxalic acid in foods such as rhubarb and soy. High fat diets can also slow down the absorption of calcium.
Estrogen plays a significant part in bone physiology, and is an important factor in the maintenance of bone density in women. Bone is living tissue, and is constantly being absorbed and remodeled throughout life. The part played by estrogen is to maintain a proper balance between the osteoclasts, the cells that reabsorb bone tissue, and osteoblasts, the cells that form new bone tissue.
When estrogen is deficient, this balance is lost and rather than bone formation and resorption occurring constantly, they take place in spurts so that first an area of new bone will be formed, then resorption will occur some weeks later, resulting in a structure where there are cavities between areas of bone. With time, these cavities will increase and weaken the integrity of the bone structure.
However, that is not the whole story. The effect of estrogen is to limit the active period of osteoclasts so that the areas of bone resorbed into the body are relatively small so that the removed bone cavity can easily fill up with new bone by the osteoblasts, which are invigorated by estrogen. When estrogen is deficient, not only is the activity of the bone-forming osteoblasts reduced, but the bone-absorbing osteoclasts activity is not regulated, and they form deeper holes in the bone structure than the osteoblasts are able to fill.
The net result is bone loss, with more bone being reabsorbed than is being formed. The end result of all this is spongy bone tissue with many tiny hole and also with larger areas of missing bone. Eventually this passes a critical point and the bone fractures during normal use. A simple jump from one step to another can fracture a bone at its weakest point, such as at the hip joint where the neck of bone is thinner.
Not everybody is at the same risk, and there are certain risk factors that you should be aware of, each of which could increase the chances of you developing weak bones. The condition particular affects white or Asian women, and those who have a small frame. If you smoke and drink an excessive amount of alcohol, you will also be more prone to osteoporosis, although exercise can help you to avoid it. An inadequate intake of calcium and vitamin D will also contribute, and magnesium is an essential part of strong bone development.
The U.S. Department of Agriculture has carried out surveys that indicate American women to be taking only 50% of the calcium recommended to maintain a healthy bone density. However, it is not only dietary calcium that is needed for the formation of bone, but also magnesium and boron, and vitamin D also helps with the absorption of calcium in the gut.
If you are on steroids then they can render you more prone to brittle bone disease. Unfortunately the symptoms of osteoporosis do not become evident until there has been a significant amount of bone loss, which is why post menopausal women, and those over 65, should have a bone density scan (DXA test). It is important to understand that osteoporosis is not a disease as such: you cannot ‘catch’ it, but it develops as the result of a gradual reduction in the minerals that maintain the density of your bone structure.
Your diet is important in helping you prevent bone loss and osteoporosis later in life, and your lifestyle is also important. Reducing your daily alcohol intake will certainly help, and cigarette smoking further retards the activity of the bone-creating cells. Calcium and vitamin D supplements will help, but do not restrict yourself only to these.
If you want to maintain proper bone density through and beyond the menopause stage of life, you should take a balanced supplement that contains a combination of vitamins and minerals needed to maintain a healthy balance between natural bone loss and regeneration. There is more to it that only calcium and vitamin D, and a balanced supplement takes this out of your hands. You can rest in the knowledge that you are doing the best for your body and its bone density.
Omega-3 Relieves Depression in Some Individuals
November 02, 2007 03:27 PM
Omega-3 oils contain fatty acids that are known as essential fatty acids because they cannot be manufactured in your body but have to be taken in your diet. They provide many benefits to your body, and are also believed to relieve depression in some individuals. First, however, an overview of the more conventional benefits of omega-3 oils.
Obtainable in your diet from oily fish such as mackerel, herring, salmon and the like, omega-3 fatty acids play an important part in your normal growth and development, and are also crucial to normal brain function. They can reduce inflammation and protect you from heart disease and some cancers. Studies have shown the fatty acids to be particularly concentrated in the brain and to be important for cognitive processes and memory.
The effects of omega 3 fish oils on the brain are well documented, and they are known to be effective treatments in some cases of bipolar and schizophrenia. It is believed that they could also be used as a treatment in other disorders such as attention deficit disorder and dyslexia, but there is as yet no evidence that this is the case.
Omega-3 fatty acids reduce the so-called ‘bad’ low density lipoprotein (LDL) cholesterol levels and increase the high density lipoproteins (HDL) that take the cholesterol back to the liver for destruction. The end result is a reduction in the cholesterol content of the blood that can be deposited on the artery walls and promote atherosclerosis. Diets high in omega-3 fatty acids appear to lower blood pressure in those suffering from hypertension, and so reduce their chances of heart attacks and strokes.
Omega 3 oils are also natural inflammatories, and help prevent conditions involving inflammation such as arthritis, asthma and menstrual cramps. They appear to help the immune system to fight these conditions and reduce the inflammation and its causes.
They are also important in the formation of prostaglandins that are responsible for the regulation of important functions such as blood pressure, blood clotting and immune response. They are hormone-like substances and also control the synthesis in the body of other hormones. If the balance of fatty acids in the diet is not right, then the subsequent imbalance in prostaglandin and hormone production can lead to disease.
It is in its effect on depression and mood, however, that has surprised many in the medical, profession. Ethyl-eicosapentaenoate, known as ethyl EPA, is a constituent of omega-3 fish oil and many studies have demonstrated that this substance helps cases of depression and related disorders. However, are people justified in turning to ethyl EPA to help them be cured of this condition?
In one study involving 20 people, six out of ten people given the supplement displayed significantly reduced symptoms of depression after four weeks. The effects were noticed as early as two weeks and many of the depression symptoms, such as worthlessness and insomnia, had improved after three weeks. This conformed with the results of many other studies that have been carried out world wide. In Scotland, a number of patients were studied who had failed to respond to traditional antidepressant drugs. Of the seventy patients involved in the trial, all of the patients who were treated with EPA displayed significant improvements in all the symptoms of their depression after four weeks whereas those with the placebo showed no improvement.
Of the two main components of omega-3 fish oil, EPA and docosahexaenoic acid (DHA), only the EPA has this property, and the EPA works best alone when the DHA has been extracted. Studies and tests have indicated that the DHA appears to be important for the brain’s structure, but the EPA for its function, hence the reason for the ineffectiveness of the former in relieving depression which is a function of the brain rather connected to its structure. In fact, depressed people have been found to be deficient in EPA in comparison to those not suffering from the condition. The original idea for this originated with the late Dr. Horribin who was pioneer in researching the effects of lipids on the biochemistry of the brain as far back as the 1970s. Since then the world-wide research has confirmed his theory. However, the reason why this theory works in practice is not yet understood. It has been established that a diet rich in trans fats can unfavorably affect the hormones in the brain that stabilize mood, possibly due to the fats slowing down the system of messaging within the brain. This kind of effect can cause depression.
This is likely due to the slowing down of the messages passing between the synapses. Brain cells communicate by means of chemicals that cross the synapses, or small gaps between the individual cells. They are not directly connected like normal electrical circuits. It has been theorized that the EPA speeds up the passage of these messages between neurotransmitters and neuroreceptors. Other theories have also been promoted, such as that the EPA has properties of its own that cure depression by another route altogether.
A possible clue could be in the findings of one study on a man aged 21 years old whose brain was scanned before and after EPA treatment. The result showed in increase in the mass of brain cells after the treatment. This was contrary to the belief that brain cells could neither be generated nor grown once a person reaches maturity.
An individual suffering depression who would like to treat themselves with EPA would have to buy a lot of oily fish since high doses are needed for this level of therapy. However, it is found in high concentrations in a few supplements available on the market, and when choosing you must use the highest grade of EPA you can get, with as low a DHA content as you can find.
There is little doubt now; however, that the EPA content of omega-3 relieves depression in some individuals, although more work is needed to prove without doubt that it is effective with all forms of depression.
Breast Cancer and Natural Supplements

Breast Cancer and Nutritional Supplements
There is probably nothing more frightening for a woman than the discovery of a lump in her breast. Cancer and all its consequences quickly come to mind. This quick association may materialize, in part, because no woman is immune. Most have a friend, a sister, a mother, or a coworker who has been diagnosed with the disease. And they know how difficult dealing with this disease can be. Fortunately, 80% of all breast lumps are not cancerous. Most are cysts or a benign clump of tissue.
Over her lifetime, a woman’s breasts undergo many, many changes. From before puberty and on, breast tissue is continually evolving. Breasts often feel different before menstrual cycle, returning to normal a few days after. Pregnancy certainly causes changes in a woman’s breasts, as does breastfeeding. And as women age, breast tissue becomes less dense.
Because of these continual changes, breast tissue especially requires adequate nutrition. While everyone benefits from a healthy diet, there are additional nutrients from which women can specifically benefit.
In this issue of Ask the Doctor, we will discuss breast cancer and the vast amount of research that has explored the role nutrition plays in this serious and still deadly disease. Specifically, we will discuss how two B vitamins, calcium D-glucarate, broccoli extract, green tea, maitake mushrooms, and iodine can all help prevent breast cancer.
Q. How can these nutrients prevent breast cancer?
A. Scientists learn a lot about disease from simply observing what is happening around them. One observation that has been recognized for many years is that certain cultures have very low incidence of breast cancer. Women n
Moms (and dads) have also learned a lot about diseases simply by observing what is happening in their families. They have notices that certain vegetables play a large role in the prevention of all types of diseases, including cancer. And, accordingly, they have been urging their offspring to eat their vegetables for several generations.
Building on these observations, scientists have designed and carried out many studies to determine what it is about these nutrients that can prevent breast cancer. What they have discovered, so far, follows. Let’s start with the B vitamins.
Deficiencies of this vitamin can result in a serious type of anemia. Nerve damage can also occur if B12 levels are too low. Researchers are now investigating whether breast cancer may, in part, be caused by a B12 deficiency as well.
Another study, this one taking place in a laboratory setting, discovered that vitamin B12, applied directly against experimental breast cancer cells, actually stopped the cancer cells from growing. The researchers conducting the experiment believe that giving vitamin B12 to women with breast cancer as part of a chemotherapy regime, might help keep the cancer in check.
Low folic acid intake is linked to the development of all cancers. This is because folic acid is crucial to the making and continual repair of DNA, the molecule that carries our genetic code. A recent study discovered that high intakes of folic acid might actually reduce the risk of breast cancer. The researchers looked at the diets of over 2600 women. During interviews with the researchers, the women reported what they usually ate. Once the data was collected, the results showed that women, who ate lots of foods that contained folic acid, had much lower rates of breast cancer.
There is no clear-cut, single cause of breast cancer. Many factors are required for the disease to appear. One such factor is estrogen. A recent study showed that women who developed breast cancer tended to have higher levels of estrogen circulating in their bodies than women without breast cancer. This means that women who got their periods before age eleven or entered menopause after age fifty-five have a higher risk of breast cancer. This also supports the theory that the number of menstrual cycles a woman has affects her risk for breast cancer.
Another factor is drinking alcohol. Because alcohol raises estrogen levels, if a woman consumes even moderate amounts of alcohol her risk of breast cancer also is increased. The link between alcohol and breast cancer may even be stronger than other dietary links. However, an important study has discovered that folic acid may uncouple this link.
A very large study of over 34,000 women recently studied the effect of folic acid on the risk of breast cancer. This project was part of the Nurses’ Health Study, an ongoing, long-term study that looks at nutrition’s role in the development of disease. The women in the folic acid and breast cancer study were followed for 12 years. The participants completed detailed food questionnaires that provided the researchers with important data.
The women were divided into four groups:
<![if !supportLists]>1. <![endif]>Women with low folic acid levels and drink alcohol
<![if !supportLists]>2. <![endif]>Women with high folic acid levels and rink alcohol
<![if !supportLists]>3. <![endif]>Women with low folic acid levels and don’t drink alcohol
<![if !supportLists]>4. <![endif]>Women with high folic acid levels and don’t drink alcohol
Within these four groups the women were further divided into subgroups according to the amount of alcohol they consumed each day and their specific folic acid intake.
The researchers found that women who consumed the lowest amounts of folic acid and drank at least one alcoholic beverage a day had the highest rate of breast cancer. In contrast, women who had high intakes of folic acid and also drank at least one alcoholic beverage a day, had the same rate of breast cancer as the women with high folic acid intakes who did not drink. In other words, women who had high levels of folic acid in their diet erased their alcohol-related increase in breast cancer risk.
It seems estrogen can be both friend and foe. While women need the hormone to soften skin, thicken hair, and fill out hips and breasts, estrogen can also nourish breast tumors, helping them grow bigger, stronger, and more deadly. Thanks, in part, to good nutrition, American women get their periods early and go through menopause alter in life. Women today also have fewer pregnancies; families with one or two children are quite common.
All of these factors increase the time women’s bodies are exposed to estrogen. As we discussed before, longer exposure means increased opportunities for estrogen to cause trouble. It is also a troubling fact of modern life that we are continuously exposed to cancer-causing chemicals and toxins. These toxins come in part from contaminants in the food we eat and pollutants in the air we breathe.
The body does have a system that eliminates some of the excess estrogen and toxic chemicals before they can cause harm. In the liver, they are bound or attached to a chemical called glucuronic acid. The bound toxin or estrogen is then excreted in bile and eventually eliminated as a waste product in the stool.
However, an enzyme called beta-glucuronidase can break this bond between estrogen and glucuronic acid. When this happens, the hormone or toxin is released from its bone, capable of causing harm once more. Increased beta-glucuronidase activity is associated with an increased risk for various cancers, particularly hormone-dependant cancers like breast cancer.
Fortunately, scientists have discovered that a natural substance found in foods calcium D-glucarate (CDG) can stop the activity of beta-glucuonidase. CDG keeps the harmful estrogen bound to glucuronidase. While CDG is found in fruits and vegetables, the amounts may not be sufficient to maintain effective levels to stop beta-glucuronidase.
CDG has been shown in experimental studies to significantly stop beast cancer growth. And several human trials are currently underway with CDG to determine its capability to decrease the breast cancer risk in women at high risk for the disease.
There are some very interesting connections between breast tissue and thyroid tissue. Iodine is an essential trace element present in a hormone of the thyroid gland and is involved in several metabolic functions. One iodine function is the protection of breast tissue from cancerous cells.
In a laboratory study, researchers exposed breast cancer cells and breast tissue without any cancer to a type of seaweed that contains high levels of iodine. The seaweed killed all of the cancerous cells, yet did not harm the normal breast cells. Japanese women frequently eat this type of seaweed and have very low rates of breast cancer. The study’s researchers believe one reason for this low incidence of breast cancer may be the iodine in the seaweed.
And, for some as yet unknown reasons, women who have thyroid cancer are at higher risk of developing breast cancer. While they are unsure why this happens, researchers are continuing to study this link, and support of healthy thyroid function remains an important consideration.
For quite some time, scientists have observed that cruciferous vegetables, such as broccoli, cabbage, and cauliflower, significantly reduce the risk of disease, including cancer. It seems a phytochemical in broccoli sulforaphane, is one of the chemicals responsible for this beneficial activity. Sulforaphane increases certain enzymes in the body called phase 2 enzymes that deactivate cancer-causing chemicals.
Breast cancer cells exposed to sulforaphane in several lab experiments showed that the compound inhibited the growth of the cancer cells up to 80 percent. Researchers are in the process of setting up clinical trials to study sulforaphane’s effect in women who have breast cancer.
There is a tall amount of research, including finding from the Nurses’ Health Study, that suggest green tea beverage consumption is associated with a lower incidence of breast cancer. In fact, researchers have long noted the low rates of breast cancer in
The active compound in green tea responsible for breast cancer inhibition is epigallocatechin-3 gallate or EGCG. When breast cancer cells are exposed to EGCG in lab experiments, the cells stop growing, lose their ability to replicate, and die.
In a recent study, researchers discovered that drinking green tea prevented the recurrence of breast cancer in women who have previously been diagnosed and treated for the disease. This study involved over 1100 Japanese women. The women who drank green tea every day had very low rates of their breast cancer returning.
For thousands of years, maitake mushrooms have been linked to good health in those who eat them. Called “dancing mushrooms” (possibly due to their wavy, rippling appearance or possibly due to the little dance of joy mushroom hunters perform when they find them in the woods), maitakes contain an important compound called D-fraction.
Not only does the D-fraction in maitake mushrooms stop the growth of cancerous tumors, it also alerts and stimulates immune cells (including macrophages and natural killer cells) to fight the disease. Maitake also inhibits some of the mechanism that promotes metastasis, or spread, of cancer cells in the lymph and bloodstream.
Because of this success, maitake is now being used in clinical trials of women with breast cancer. One study reported significant improvement of symptoms, including reduction of the tumor. The maitake was given to breast cancer patients in addition to standard chemotherapy.
Q. Should these nutrients be used in place of traditional treatment for breast cancer?
A. Absolutely not. None of these nutrients can cure breast cancer. However, they can be a part of a validated plan of treatment. If you have breast cancer, talk to your health care practitioner about these nutrients. Remember, nutritional supplements are just that: supplements to food, medication, and treatment. They are intended to enhance and prevent, not replace.
Despite apprehension in performing self-breast exams, women are very proactive in their health. Yearly mammograms and pap tests have been an important part of their lives for many years, and newer and more accurate diagnoses are emerging. The prevention of health problems in themselves and their families has always been a high priority for women. And for women, nutrition has played an important part of health problem prevention.
Nutritionally speaking, what benefits your breasts benefit your whole body. However, as we have learned, there are specific links between nutrition and developing breast cancer that seem to be fairly strong.
Making a few changes may reduce the risk of developing the disease. The nutrients listed here, vitamin B12, folic acid, calcium d-glucarate, iodine, broccoli, green tea, and maitake mushrooms can be an important part of a woman’s preventative health regimen.
Best Sugar Balance Svetol (green coffee extract)
May 05, 2006 06:30 PM
Best Sugar Balance featuring Svetol® Svetol® is an extract of green coffee obtained by the use of a traditional patented extraction process from the beans of the species Coffea canephora robusta Pierre. This species is particularly rich in the constituent known as chlorogenic acid. Svetol® green coffee extract contains less than 2% caffeine. The extract is standardized to contain between 45-50% chlorogenic acids.
In vitro (test tube) and in vivo research suggests that chlorogenic acids present in coffee may have the ability to regulate blood sugar concentrations after meals by acting on the intestinal absorption of glucose and improving the body's glucose tolerance. Clinical evidence also suggests that Svetol® green coffee extract may help to maintain a healthy blood sugar level when used as a part of the diet.*
Maintains healthy blood sugar levels when used as a part of the diet*
Chlorogenic acid is the major polyphenol compound found in Svetol® green coffee bean extract. In vitro and animal studies have been conducted to determine the potential actions of this polyphenol. Studies report that chlorogenic acid and related compounds have significant antioxidant potential and are responsible for the high reported antioxidant benefit of green coffee. Several studies suggest that consumption of coffee in the diet is one factor that is correlated to the maintenance of healthy neural function and healthy aging. Coffee has also been shown in vitro to suppress the production of various free radicals. The chlorogenic acid content of coffee has been determined to be a major factor in the free radical quenching properties of coffee. A study was conducted to assess the activity of coffee extracts against the production of hydroxyl radicals in an in vitro system. It was found that coffee extracts possessed significant suppressive activity against hydroxyl radicals. Of the compounds assumed to be responsible for this effect, the researchers concluded that the chlorogenic acids played a major role with some contributions from other compounds found in the extract. This compound may also strongly contribute to any potential neuroprotective effects seen with coffee consumption.1
Two further studies highlight a possible mechanism by which chlorogenic acid mediates its antioxidant activity. In one study, the FRAP (Ferric Reducing Antioxidant Power) assay was used to measure and compare the iron-reducing capacity of chlorogenic acid and caffeine. It was shown that the chlorogenic acid content of the samples tested was highly correlated with iron-reducing activity in this assay. Moreover, lighter roasted coffee samples (closer in nature to green coffee) had the highest iron-reducing activity. Caffeine did not influence the iron-reducing activity of the coffee samples.2 Iron compounds are known to mediate the production of radicals and often serve as catalysts for their production in the body. A second study shows that chlorogenic acid can bind to and Chelate certain iron compounds, preventing them from catalyzing radical-producing reactions. In this way, chlorogenic acid acts as a powerful antioxidant.3
Chlorogenic acid and related compounds have a dual effect on the production and suppression of free radicals. In the case of the hydroxyl radical, studies outlined previously suggest that chlorogenic acid suppresses the production of the radical due to its ability to chelate iron compounds, while other studies suggest that chlorogenic acid has direct scavenging effects on the hydroxyl radical.4 Dietary intake of this potent polyphenol may confer multiple benefits to human health.
Several studies further suggest that chlorogenic acid in coffee can have a beneficial effect on blood sugar levels when consumed as a part of the diet. A recent study assessed the effects of coffee and tea consumption on glucose tolerance in middle-aged Japanese men. In this study, the relationship between daily intakes of green tea or coffee and glucose tolerance status was measured by the oral glucose tolerance test (OGTT). More than 3,400 men participated in the study in which fasting glucose was measured before and 2 hours after administration of an oral glucose load. A self-administered questionnaire was used to establish daily levels of dietary coffee and green tea consumption over the past year. The results showed that those individuals who consumed the highest levels of coffee per day had lower fasting glucose levels (by 1.5%) and lower post-test glucose concentrations (4.3% lower) than those who did not consume coffee Chlorogenic acid and related compounds have a dual effect on the production and suppression of free radicals. In the case of the hydroxyl radical, studies outlined previously suggest that chlorogenic acid suppresses the production of the radical due to its ability to chelate iron compounds, while other studies suggest that chlorogenic acid has direct scavenging effects on the hydroxyl radical.4 Dietary intake of this potent polyphenol may confer multiple benefits to human health.

In this study, green tea consumption was not associated with any benefits on glucose concentrations.5
It is likely that the chlorogenic acid found in coffee plays a role in supporting healthy glucose metabolism, whereas the role of caffeine is not clear, with some reports suggesting an adverse effect on sugar metabolism.
A second study further confirms an effect of chlorogenic acid at inhibiting the absorption of glucose from the diet. This effect occurs in the small intestine. In this study, nine healthy fasted volunteers consumed 25 grams of glucose in 400 ml of water (the control group), caffeinated coffee, or decaffeinated coffee. Frequent blood samples were taken over the next 3 hours. It was found that glucose and insulin concentrations were higher 30 minutes after the consumption of caffeinated coffee than with either decaffeinated coffee or control (water).While caffeine has specific biological effects on raising glucose levels and impacting insulin profiles, chlorogenic acid was shown to have an antagonistic effect on glucose transport. Previous studies have also shown that chlorogenic acid significantly delays glucose uptake from the small intestine.6
RESEARCH ON SVETOL®
Svetol® is a unique extract of Coffea canephora robusta green coffee beans containing between 45 and 50% chlorogenic acids with less than 2% total caffeine concentration. As outlined above, many studies highlight the potential benefits of coffee compounds, including chlorogenic acid, for providing protection against free radicals and promoting healthy glucose metabolism. A number of other potential benefits have been discovered for these compounds. Svetol® has also been the subject of preliminary clinical studies that have shown exciting results.
In a pilot study, the effect of Svetol® on sugar concentrations after meals was evaluated in 15 individuals. In the same trial, the longer-term effects of Svetol® on weight management were also evaluated. Blood sugar concentrations were measured on two separate occasions. Patients were administered an oral glucose tolerance test (OGTT) in which they consumed a standard amount of sugar and had their blood sugar levels measured 1 hour after sugar intake. The first measurement was made on day 1 prior to taking Svetol® and the second OGTT was performed on day 2, after beginning the Svetol® regimen in which one tablet (200 mg per tablet) was administered 3 times during the day. Patients were fasted for at least 8 hours prior to the testing. The results showed that Svetol® was able to reduce blood sugar concentrations in 60% of the subjects. The mean reduction of blood sugar concentration in these individuals was 50%. The treatment was continued following the same regimen for 6 weeks to assess the impact of Svetol® on weight. The average weight loss of the participants was 1.5 kg (3.3 lbs) over the treatment period. 7
Based on the studies mentioned above and other related research on the ingredients in Svetol®, scientists have proposed two mechanisms of action whereby Svetol® may influence the metabolism and processing of glucose. The first mechanism seems to be an inhibitory action on glucose absorption from the diet. Svetol® may affect the uptake of glucose in the small intestine by modulating factors needed for sugar absorption.
The second mechanism relates to possible effects of Svetol® in the liver's ability to produce glucose. Chlorogenic acids have been shown in vitro and in animal studies to modulate the effects of certain enzymes in the liver that catalyze the production of glucose. By having this dual effect on sugar absorption and sugar production, Svetol® is an effective product for maintaining healthy blood sugar levels when used as a part of the diet.*
Svetol® is a natural food extract from green coffee beans containing a standardized amount of chlorogenic acid. Studies have shown that chlorogenic acid (up to 500 mg/kg/day) given to pregnant rats from the 5th through 12th day of gestation caused no maternal or fetal mortality and no adverse effects on the nervous system. Chlorogenic acids have also been shown to be non-mutagenic in tests on bacteria such as the Ames test. The LD50 of chlorogenic acids has been determined to be higher than 2500 mg/kg body weight. Svetol® is also extremely low in caffeine, with less than 2% caffeine contained in the extract, and is not expected to have any of caffeine's stimulant effects. Svetol® is extremely safe with no adverse effects having been reported while taking Svetol® at the recommended dosage.7

July 15, 2005 09:16 AM
A recent study (August, 1996) exploring the effect of Hypericum perforatum on depression re vealed some fairly stunning results. The British Medical Jo u rn a l published the results of one major studies, which consisted of twenty - three randomized trials, including a total of 1757 outpatients with mainly mild or moderately seve re depressive disorders. Testing was conducted with single preparations and combinations of extracts of the plant, and with placebo and anther drug treatment. As just mentioned, the results were very promising. In all aspects of the study, Hypericum extracts were shown to be “significantly superior” to placebo and similarly effective as standard antidepressants. There were nearly twice the number, percentage-wise, of dropouts due to side effects from the standard drugs than those taking the Hypericum extracts. Side effects occurred in eighty-four patients using standard antidepressants, while only fifty patients taking the Hypericum extracts experienced side effects. And the scores on the Hamilton depression scale, which measures severity of one’s depression, showed those taking Hypericum treatments scored slightly higher than those taking the standard antidepressant and significantly higher than those taking the placebo. 9 This study provides some firm ground for St. John’s wort to stand on in the treatment of depression, both in sheer numbers and its quality of treatment.
Another contemporary study, carried out in 1995 by Witte, et. al, showed the Linde study to be accurate in its findings. This particular study, carried out as a multicenter, placebo-controlled double-blind trial, used a highly concentrated Hypericum preparation to treat ninety-seven outpatients. The course of the illness was assessed with the Hamilton Depression Scale, the von Zerssen Depressivity Scale and the Clinical Global Impression Scale. The authors of the study noted this in their abstract:
Treatment resulted in an appreciable improvement in the symptoms of depression, and the seventy percent response rate (n=43) corresponded to that of chemical antidepressants. The preparation also showed an anxiolytic effect. The substance [hypericum] was extremely well tolerated, and no side effects were reported by any of the patients.10 Again, this study’s findings correlate that of the Linde and other studies in that treatment with Hypericum is at least as effective as standard synthetic antidepressants without producing near the number of side effects.
The Nursing Times also reported on recent findings dealing with Hypericum’s effect on depression. Stating that psychiatric medications are notorious for their undesirable side effects, and that the need for safer antidepressants is widely acknowledged, the blurb refers to a double-blind study, done by G. Harrer and H. Sommer (published in Phytomedicine, 1994 (1): 3-8), using St. John’s wort on 105 patients experiencing mild to moderate depression. They were aged twenty to sixty-four and had diagnoses of “neurotic depression or temporary depressive mood.” Patients were divided into two groups and monitored over four weeks, with one group receiving 300 mg of Hypericum extract three times daily and the other group receiving a placebo. All patients received psychiatric evaluations before the start of the study and after two and four weeks of treatment.11
The results of the study support the findings of other recent studies dealing with Hypericum and depression: 67 percent of the Hypericum group had responded positively to the treatment without any adverse side effects, whereas only 28 percent of the placebo group displayed any improvement. Harrer and Sommer state that the patients treated were experiencing strictly mild forms of depression; combining this with the study’s results and the results of other studies suggest that Hypericum treatment can be a very effective treatment for mild to moderate depression without severe side effects. The authors themselves even recommended that Hypericum should be considered as a remedy of choice. 12
These and other studies point to the strong possibility of using St. John’s wort, and specifically hypericin, on a wide scale to treat various forms of depression. Linde’s study suggests that St. John’s wort may have its most valuable asset in that of few or no side effects, something many sufferers of depression are very concerned about. The authors do note, however, that more research is necessary, especially in determining the severity and nature of depression, length of treatment, treatment dosage, preparation of Hypericum extracts, and occurrence of long-term side effects. Nevertheless, the results of this study and others are extremely promising for the millions of those who suffer from depression.
Pain - Post Op and Relaxation
July 13, 2005 09:24 AM
Relaxation, Music Reduce Post-Op Pain. New research has found that relaxation and music, separately or together, significantly reduce patients' pain following major abdominal surgery. The study, published in the May issue of the journal Pain, found that these methods reduce pain more than pain medication alone. Led by Marion Good, PhD, RN, of Frances Payne Bolton School of Nursing, Case Western Reserve University, Cleveland, Ohio, the study is supported by the National Institute of Nursing Research (NINR), at the National Institutes of Health. "This is important news for the millions of Americans who undergo surgery and experience postoperative pain each year," said Dr. Patricia A. Grady, director of the NINR.
"Better pain management can reduce hospital stays and speed recovery, ultimately improving patients' quality of life." Dr. Good and her research team studied three groups of patients undergoing abdominal surgery. In addition to the usual pain medication, one group used a jaw relaxation technique, another group listened to music, and a third group received a combination of relaxation and music.
Findings revealed that, after surgery, the three treatment groups had significantly less pain than the control group, which received only pain medication. "Both medication and self-care methods which involve patient participation are needed for relief," said Dr. Good.
"These relaxation and music self-care methods provide more complete relief without the undesired side effects of some pain medications." The findings have important implications for the 23 million people who undergo surgery and experience postoperative pain annually in the United States. Pain can hamper recovery by heightening the body's response to the stress of surgery and increasing tissue breakdown, coagulation and fluid retention. Pain also interferes with appetite and sleep and can lead to complications that prolong hospitalization.
Dr. Good and her research staff worked with 500 patients aged 18-70, who were undergoing gynecological, gastrointestinal, exploratory or urinary surgery. Prior to surgery, those in the music, relaxation or combination groups practiced the techniques. The relaxation technique consisted of letting the lower jaw drop slightly, softening the lips, resting the tongue in the bottom of the mouth, and breathing slowly and rhythmically with a three-rhythm pattern of inhale, exhale and rest. Patients in the music group chose one of five kinds of soothing music--harp, piano, synthesizer, orchestral or slow jazz.
On the first and second days after surgery, all patients received morphine or Demerol for pain relief by pressing a button connected to their intravenous patient controlled analgesia pumps. The groups receiving the additional intervention used earphones to listen to music and relaxation tapes during walking and rest, while the control group did not. The research team measured the patients' pain before and after 15 minutes of bed rest and four times during walking to see if the sensation and distress of pain changed.
Dr. Good found that during these two days postsurgery the three treatment groups had significantly less pain than the control group during both walking and rest. "Patients can take more control of their postoperative pain using these self-care methods," says Dr. Good. "Nurses and physicians preparing patients for surgery and caring for them afterwards should encourage patients to use relaxation and music to enhance the effectiveness of pain medication and hasten recovery."
Dr. Good's findings have implications for future research into the effectiveness of self-care methods on other types of pain, including chronic pain, cancer pain, and pain of the critically ill.
Vitamin D Lack Linked to Hip Fracture. Vitamin D deficiency in post-menopausal women is associated with increased risk of hip fracture, according to investigators at Brigham and Women's Hospital in Boston, Mass. In a group of women with osteoporosis hospitalized for hip fracture, 50 percent were found to have a previously undetected vitamin D deficiency. In the control group, women who had not suffered a hip fracture but who were hospitalized for an elective hip replacement, only a very small percentage had vitamin D deficiency, although one-fourth of those women also had osteoporosis. These findings were reported in the April 28, 1999, issue of the Journal of the American Medical Association.
The study, conducted by Meryl S. LeBoff, MD; Lynn Kohlmeier, MD; Shelley Hurwitz, PhD; Jennifer Franklin, BA; John Wright, MD; and Julie Glowacki, PhD; of the Endocrine Hypertension Division, Department of Internal Medicine, and Department of Orthopedic Surgery, Brigham and Women's Hospital, Boston, was supported by grants from the National Institute on Aging (NIA) and the National Center for Research Resources (NCRR. These investigators studied women admitted to either Brigham and Women's Hospital or the New England Baptist Hospital, both in Boston, between January 1995 and June 1998.
A group of 98 postmenopausal women who normally reside in their own homes were chosen for the study. Women with bone deterioration from other causes were excluded from the study.
There were 30 women with hip fractures caused by osteoporosis and 68 hospitalized for elective joint replacement. Of these 68, 17 women also had osteoporosis as determined by the World Health Organization bone density criteria. All the participants answered questions regarding their lifestyle, reproductive history, calcium in their diet, and physical activity.
Bone mineral density of the spine, hip, and total body were measured by dual X-ray absorptiometry (DXA) technique, as was body composition. Blood chemistry and urinary calcium levels were analyzed. The two groups of women with osteoporosis did not differ significantly in either time since menopause or bone density in the spine or hip. They did, however, differ in total bone density.
The women admitted for a hip fracture had fewer hours of exercise than the control group. Fifty percent of the women with hip fractures were deficient in vitamin D, 36.7 percent had elevated parathyroid hormone (PTH) levels (a hormone which can stimulate loss of calcium from bone), and 81.8 percent had calcium in their urine, suggesting inappropriate calcium loss. Blood levels of calcium were lower in the women with hip fractures than in either elective group.
These researchers propose that vitamin D supplementation at the time of fracture may speed up recovery and reduce risk of fracture in the future. Current Dietary Reference Intake Guidelines contain a daily recommendation of 400 IU of vitamin D for people aged 51 through 70 and 600 IU for those over age 70.
"We know that a calcium-rich diet and regular weight-bearing exercise can help prevent osteoporosis. This new research suggests that an adequate intake of vitamin D, which the body uses to help absorb calcium, may help women to reduce their risk of hip fracture, even when osteoporosis is present," observed Dr. Evan C. Hadley, NIA Associate Director for geriatrics research.
"Osteoporosis leads to more than 300,000 hip fractures each year, causing pain, frequent disability, and costly hospitalizations or long-term care. "Prevention of such fractures would greatly improve the quality of life for many older women and men, as well as significantly reduce medical costs." The bones in the body often undergo rebuilding. Some cells, osteoclasts, dissolve older parts of the bones. Then, bone-building cells known as osteoblasts create new bone using calcium and phosphorus.
As people age, if osteoporosis develops, more bone is dissolved than is rebuilt, and the bones weaken and become prone to fracture. Also in many older persons, levels of vitamin D in the blood are low because they eat less or spend less time in the sun, which stimulates the body's own production of vitamin D.
Experts do not understand fully the causes of osteoporosis. However, they do know that lack of estrogen which accompanies menopause, diets low in calcium, and lack of exercise contribute to the problem. Eighty percent of older Americans who face the possibility of pain and debilitation from an osteoporosis-related fracture are women. One out of every two women and one in eight men over the age of 50 will have such a fracture sometime in the future. These fractures usually occur in the hip, wrist, and spine.
Sleep Apnea, Diabetes Link Found. Adults who suffer from obstructive sleep apnea are three times more likely to also have diabetes and more likely to suffer a stroke in the future, according to a new UCLA School of Dentistry/Department of Veterans Affairs study published today in the Journal of Oral and Maxillofacial Surgery. Sleep apnea, a serious condition marked by loud snoring, irregular breathing and interrupted oxygen intake, affects an estimated nine million Americans. The culprit? Carrying too many extra pounds.
"The blame falls squarely on excess weight gain," said Dr. Arthur H. Friedlander, associate professor of oral and maxillofacial surgery at the UCLA School of Dentistry and associate chief of staff at the Veterans Affairs Medical Center in Los Angeles. Surplus weight interferes with insulin's ability to propel sugars from digested food across the cell membrane, robbing the cells of needed carbohydrates. Diabetes results when glucose builds up in the bloodstream and can't be utilized by the body. Being overweight can also lead to obstructive sleep apnea, according to Friedlander.
"When people gain too much weight, fatty deposits build up along the throat and line the breathing passages," he explained. "The muscles in this region slacken during sleep, forcing the airway to narrow and often close altogether." Reclining on one's back magnifies the situation. "When an overweight person lies down and goes to sleep," Friedlander said, "gravity shoves the fat in the neck backwards. This blocks the airway and can bring breathing to a halt."
Friedlander tested the blood sugar of 54 randomly selected male veterans whom doctors had previously diagnosed with obstructive sleep apnea. He discovered that 17 of the 54 patients, or 31 percent, unknowingly suffered from adult-onset diabetes. Using the same sample, Friedlander also took panoramic X-rays of the men's necks and jaws. The X-rays indicated that 12 of the 54 patients, or 22 percent, revealed calcified plaques in the carotid artery leading to the brain.
These plaques block blood flow, significantly increasing patients' risk for stroke. Seven of the 12, or 58 percent, were also diagnosed with diabetes. In dramatic comparison, the 17 patients diagnosed with diabetes showed nearly twice the incidence of blockage. Seven of the 17 men, or 41 percent, had carotid plaques. Only five of the 54 patients who displayed plaques did not have also diabetes. If he conducted this study today, Friedlander notes, he would likely find a higher number of diabetic patients. After he completed the study in 1997, the American Diabetes Association lowered its definition for diabetes from 140 to 126 milligrams of sugar per deciliter of blood.
"This is the first time that science has uncovered a link between sleep apnea and diabetes," said Friedlander. "The data suggest that someone afflicted with both diabetes and sleep apnea is more likely to suffer a stroke in the future." "Persons going to the doctor for a sleep-apnea exam should request that their blood be screened for diabetes, especially if they are overweight," he cautioned. More than half of the individuals who develop diabetes as adults will need to modify their diet and take daily insulin in order to control the disease, he added.
Stress, Surgery May Increase CA Tumors. Stress and surgery may increase the growth of cancerous tumors by suppressing natural killer cell activity, says a Johns Hopkins researcher.
Malignancies and viral infections are in part controlled by the immune system's natural killer (NK) cells, a sub-population of white blood cells that seek out and kill certain tumor and virally infected cells. In a study using animal models, natural killer cell activity was suppressed by physical stress or surgery, resulting in a significant increase in tumor development.
These findings suggest that protective measures should be considered to prevent metastasis for patients undergoing surgery to remove a cancerous tumor, according to Gayle Page, D.N.Sc., R.N., associate professor and Independence Foundation chair at the Johns Hopkins School of Nursing. "Human studies have already found a connection between the level of NK activity and susceptibility to several different types of cancer," says Page, an author of the study.
"We sought to determine the importance of stress-induced suppression of NK activity and thus learn the effects of stress and surgery on tumor development. "Many patients undergo surgery to remove cancerous tumors that have the potential to spread. If our findings in rats can be generalized to such clinical settings, then these circumstances could increase tumor growth during or shortly after surgery." The research was conducted at Ohio State University College of Nursing and the Department of Psychology at UCLA, where Page held previous positions, and at Tel Aviv University.
Results of the study are published in the March issue of the International Journal of Cancer. In laboratory studies, Page and her colleagues subjected rats to either abdominal surgery or physical stress, and then inoculated them with cancer cells. In the rats that had undergone surgery, the researchers observed a 200 to 500 percent increase in the incidence of lung tumor cells, an early indicator of metastasis, compared with rats that had not received surgery.
The experiment also showed that stress increased lung tumor incidence and significantly increased the mortality in the animals inoculated with cancer cells. "Our results show that, under specific circumstances, resistance to tumor development is compromised by physical stress and surgical intervention," says Page.
"Because surgical procedures are life-saving and cannot be withheld, protective measures should be considered that will prevent suppression of the natural killer cell activity and additional tumor development. "Researchers do not yet know how to prevent surgery-induced immune suppression, but early animal studies have shown increased use of analgesia reduces the risk."
The study was funded by the National Institutes of Health, and the Chief Scientist of the Israeli Ministry of Health. Lead author was Shamgar Ben-Eliyahu, Ph.D., and other authors were Raz Yirmiya, Ph.D., and Guy Shakhar.
GREEN TEA EXTRACT - For Antioxidant Support
June 29, 2005 01:16 PM
For centuries the art of drinking and serving tea has played a major cultural role in many Asian countries. Americans are now discovering this healthful brew. Studies have shown that green tea is a powerful antioxidant that supports cardiovascular health and promotes dental health and glucose metabolism. The polyphenols are the most beneficial components in green tea, especially the catechin EGCG. Source Naturals offers two convenient ways to get the benefits of green tea: a highly concentrated, 100 mg GREEN TEA EXTRACT or the higher potency 500 mg GREEN TEA EXTRACT. Both extracts are standardized for polyphenols, particularly EGCG.
The Tale of Tea
Green, black and oolong teas are all processed from the young leaves of Camellia sinensis, a white-flowered evergreen that originated in southeastern Asia. Monks brought it to Japan and from there it spread around the world. The three basic types of tea are classified by processing method. Black tea is made by fermenting and roasting the leaves, giving it a dark color and rich taste. Oolong is partially fermented. Green tea is lightly steamed so it retains the chlorophyll of the leaf and its green color, along with high concentrations of polyphenol compounds.
The Science of Green Tea
All teas contain polyphenols, which are chemical compounds that act as antioxidants. In green tea the main polyphenols are the catechins, including gallocatechin (GC), epigallocatechin (EGC), epicatechin (EC), and epigallocatechin gallate (EGCG). Studies have shown that these catechins are the beneficial, health-promoting components of green tea, especially EGCG, a proven powerful antioxidant.
Catechins have significant antioxidant power and may prove to be heart healthy agents in combating lipid peroxidation within the cell membranes that line arterial walls. Antioxidants neutralize destructive free radicals and support cardiovascular health by preventing the oxidation of cholesterol. Oxidized cholesterol is an unstable molecule that damages the integrity of arteries. Research shows that EGCG is a much more potent antioxidant than vitamin C or vitamin E. The catechins in green tea have been shown to fight foreign organisms and help prevent the plaque buildup that leads to poor dental health. Research shows that green tea also promotes healthy glucose levels in the blood stream by enhancing the action of insulin.

CLA and Cows
June 22, 2005 09:52 PM
CLA and Cows
Nutritional developments like that of CLA couldn’t come at a better time. America is a nation obsessed with weight, but successes in battling weight seem harder and harder to come by. Is there a nutritional reason for this? Have we been barking up the wrong tree in recent years, starving ourselves for fear of gluttony rather than looking at broader nutritional reasons for fat accumulation? For example, Dr. Cook says that modern nutritional dogma is that fat is bad. “I’m not sure the dogma’s right. We need to get down to very specific fatty acids.”51 One of the most exciting developments coming from CLA research is that modern animal-raising techniques may be partially responsible for those of us who eat meat getting fat around the middle, even though our consumption of meat may have declined or, at least, stayed about the same in recent years.
CLA has been declining in our diet. This one nutrient’s lack may mean many of us are gaining fat, despite eating less overall fat.52
This desire to simply eliminate fats without looking at the broader nutritional picture has its roots deep in our culture. The desire to starve ourselves to lose weight goes back centuries. We have often thought weight gain came solely from lacking self-control when, often, nothing could be further from the truth.
Take for example the experiences of conscientious objectors during World War II. These men who chose, for religious reasons, not to fight in the war, contributed in other ways. One group at the University of Minnesota underwent forced starvation to help scientists learn ways to help concentration camp victims recover after liberation.
Science learned many useful things, but one thing stands out. The objectors grew more hungry as they recovered and ended up weighing five percent more after they recovered than before the experiment began. (The same can be said for refugees and concentration camp victims, who also weighed more, on average after their ordeals than before.)53 This idea of dieting being the full answer to weight loss still persists, often tragically. Many have died of anorexia, obsessed with self-image. Others have died directly from ill-conceived meal replacement programs.54 In the 1980s, Americans spent $15 billion on diet soft drinks alone,55 but consumers weighed more on average when the decade was over than when it began. You’d think all of this energy and dieting spent on the effort would have helped people lose weight. (Thankfully, many people have succeeded in losing weight and keeping it off. According to Dr. Pariza, this may well be the most significant part of CLA, not so much in losing the weight, but in helping people keep it off.56)
To drive the point home further, consider your parents. They ate a diet that was likely higher in fat than yours. They never saw “lite” versions of snacks in the store. Yet they, in general, weighed less than we do. Why? Surely exercise may have had something to do with it, but, no one has the complete answer. It seems likely that nutrition too played a role. CLA itself may hold part of the reason. As we have seen, CLA nutrition means less fat and more protein in our bodies. Recent research is showing that the amount of CLA in cows has dropped substantially since the times of our parents. In 1963, scientists found that CLA was as much as 2.81 percent of milkfat. The amount of CLA in the milk products varied with the seasons. At some times during the year, cows ate grass. At other times, they ate feed. However, in 1992, Pariza and his colleagues did a large food survey and found that this variation in CLA is no longer occurring. Furthermore, the amount of CLA in dairy products rarely gets above 1 percent of the milkfat. 57
In another research paper in 1994, scientists noticed that Australian cows have as much as three or four time the amount of CLA in the meat from similar American animals. Why? These differences probably “reflect different feeding conditions.” 58
Today, farmers use more efficient feeding methods that rely less heavily on natural grasses. This means less CLA in the meat we eat, and less CLA can mean a higher percentage of fat on our bodies. Consider too that skim milk contains virtually no CLA with its no fat content. This lack of CLA may actually hinder some people’s efforts to lose weight.
The lesson here seems to be that gluttony guilt would be better focused on balanced living. Healthy lifestyles coupled with the right supplementation can make a difference. CLA, though no magic bullet, adds to this lifestyle and could be the key that finally opens many weight (and fat) management doors. It could help many people keep the weight off.
Botanical Arsenal - Plants can help our bodies fight off cancer's deadly ...
June 13, 2005 10:31 AM
Botanical Arsenal by Fred Thomas Energy Times, May 3, 1999
The complexities surrounding the various types of cancer stem from the variety of ways in which these diseases can wreak their havoc. Luckily, the equally complex world of plants contains novel compounds that can help our bodies fight off cancer's deadly progress.
Research into these botanical compounds is mushrooming. An example: The mighty maitake, a fungus with flair, alternately known as the king (it can grow as large as a basketball, worth its weight in silver to the ancient Japanese); the prince; the Hen of the Woods (it sticks out of from trees when it grows in the wild); and the dancing mushroom to those who leaped for joy when they found one growing in its native northeastern Japan.
Researchers today dub it with a new moniker: Herbal Heavyweight.
Mushroom with Potential
The maitake, with such other medicinal mushrooms as shiitake and reishi, historically has been eaten to promote general well-being and vitality. In the modern lab, however, scientists focus on the potent immune enhancing powers of maitake, which spotlight its cancer fighting potential.
Twenty years ago, maitake, Grifola frondosa, was an obscure, largely unavailable mushroom. A series of significant Japanese studies then catapulted it into prominence-and popularity.
Hiroaki Nanba, PhD, of the department of immunology at Kobe Women's College of Pharmacy on Kobe, Japan, and a leading international researcher on maitake, conducted the preliminary tests on the mushroom, demonstrating that it stimulates immune function and inhibits tumor growth.
In 1986, Dr. Nanba fed powdered maitake to mice injected with tumor cells; 86.3% displayed inhibited tumor growth.
Dr. Nanba and his colleagues went on to run additional mouse tests, finally reporting that this potent mushroom "directly activates various effector cells (macrophages, natural killer cells, killer T-cells, etc.) to attack tumor cells."
From then, maitake mushrooms were headed to fame as cancer ninjas.
Stoking The Immune Engine
Like other mushrooms, maitake is rich in complex polysaccharides, immunomodulators that successive tests after Dr. Nanba's have shown to be effective in cancer and AIDS treatment.
The polysaccharides in maitake have a unique structure, rendering them some of the most powerful to be studied (Chem Pharm Bull 1987:35:1162-8).
What makes maitake a particularly hot property is beta-D-glucan, its primary polysaccharide. Studies show that the body absorbs it readily, at which point it effectively stimulates interleukin-1, natural killer cells and macrophages, anti-tumor warriors that battle solid cancers (Chemotherapy 1990;38:790-6; also International Conference on AIDS, Amsterdam, 1992).
Effective And Safe
In addition to lab tests, trials on people have shown that maitake may offer powerful therapy against liver and stomach cancer (studies in China), breast and colon cancer (US research) and Kaposi's Sarcoma, the virulent cancer attacking AIDS sufferers.
Importantly, studies show that no side effects or interactions accompany maitake's efficacy.
Maitake fortunately has won the interest and enthusiasm of the scientific community. Currently, researchers at the Cancer Treatment Centers of America, headed by Denis Miller, MD, are completing an exhaustive test of the anticancer and immunostimulatory actions of maitake on folks with advanced colorectal cancer. These investigators hypothesize that the polysaccharide beta-glucans derived from the fruitbody of maitake fight tumors and boost immune function. "Though it cannot be said that maitake ...[is] the cancer cure," said Dr. Nanba in his closing remarks at the Adjuvant Nutrition in Cancer Treatment Symposium in Tampa, Florida, in October 1995, "one can safely say that they do maintain the quality of life of patients and improve the immune system, resulting in the possible remission of cancer cells with no side effects."
More Bodily Benefits
Maitake maven Dr. Nanba also has tested-with strongly positive results-the effect of maitake on blood glucose, insulin and triglycerides in mice, whose levels of all three substances declined when they were fed the mushroom (H. Nanba working paper, Anti-Diabetic Activity by Maitake Mushroom, 1994).
With colleagues, Dr. Nanba showed that maitake lowered blood pressure in hypertensive rats (Chem. Phann. Bu//36:1000-1006,1988). Other studies suggest it may accelerate weight loss.
This admirable adaptogen (meaning it helps the body adapt to stress and normalize its functions) is water soluble and may be eaten in food or taken as a supplement. Vitamin C is believed to intensify maitake's beta-glucans and enhance their absorption.
It's not just what you eat that may help protect against cancer, but what you drink as well. Research from China and Japan, where tea is the everyday drink and rates of several cancers like breast and prostate are lower, may persuade you to turn over a new leaf in your own beverage choice. One of the first studies to spark interest in tea came from Shanghai (Journal of the National Cancer Institute, June 1, 1994), where people who drank two to three cups a day were found to have about a 60% reduction in the risk of cancer of the esophagus. The reason: tea leaves contain compounds called polyphenols, potent antioxidants.
In fact, in tests at the University of Kansas, three of these, known as catechins, far outshone the common antioxidant vitamins C and E. Clinical trials are just starting, but early results are encouraging. A team of Chinese scientists reported that in a third of people with precancerous mouth sores who drank three cups of a mixture of green and black tea the lesions shrank significantly.
Researchers at the Saitama Cancer Center in Japan found that green tea seems to improve the prognosis of breast cancer. They followed a group of women with early-stage tumors for seven years. Those who drank more than five cups of green tea a day were only half as likely to suffer a recurrence as patients who consumed fewer than four cups a day.
And at the University of Indiana, toxicologist James Klaunig found that the lungs of cigarette smokers who drank the equivalent of six cups of tea a day suffered 40 to 50 percent less damage from the toxins in smoke, potentially lowering their risk of lung cancer and other pulmonary problems. Simultaneously, research from Purdue University suggests tea's cancer-discouraging powers go beyond being an antioxidant. Scientists Dorothy and D. James Morre showed that a tea catechin dubbed EGCG inhibits a growth-promoting enzyme on the surface of many cancer cells-happily without affecting normal cells. And researchers at the Ohio State University College of Medicine found that EGCG counteracted another enzyme, urokinase, that helps cancer cells spread. To top it off, Mayo Clinic scientists recently showed that EGCG prompted prostate cancer cells to commit suicide (Cancer Letters, Aug. 14, 1998).
So far, most tea research has focused on green tea, and investigators agree it's more potent than the black tea most Americans favor. But because both kinds come from the same plant, Camellia sinensis (it's the processing that makes the difference as black tea is fermented, green tea isn't) both contain cancer-fighting polyphenols, just in different quantities. As long as the tea you drink (even decaffeinated) is fresh brewed, it's likely to provide some benefit; powdered and prepared teas probably don't. And adding milk may dilute the effect.
Astragalus Against Tumors
Astragalus, an herb commonly used in Asia to boost stamina, has impressed western doctors for its potential for helping people cope with chemotherapy. As John Diamon, MD, W. Lee Cowden, MD and Burton Goldberg point out in the Definitive Guide to Cancer (Future Medicine), "Astragalus appears to protect the liver against the harmful toxic effects of chemotherapy and may be effective in treating terminally ill liver cancer patients." (They cite a study in the Jrnl of Ethnopharmacology 1990, 30:145-149.) In addition, they point out, research in Japan supports using a ginseng-astragalus combination to improve the function of natural killer (NK) cells which can boost immunity (Japanese Jrnl of Allergy, 37:2, 1998, 107-114).
Other studies confirm astragalus' potential in fighting off cancer. Research at the General Hospital of PLA, Beijing, showed that flavonoids (pigments) in astragalus could help protect cell membranes from oxidative damage caused by ultraviolet exposure (Chung Kuo Chung Yao Tsa Chih, 21(12):746-8; 1996 Dec).
A study of laboratory animals at Cunma University in Maebashi, Japan, found that Astragalus could help preserve immune function against the harmful side effects of chemotherapy (Chung Kuo Chung Hsi I Chieh Ho Tsa Chih, 15(2):101-3, 1995 Feb).
Like a flame attracting moths, garlic bulbs have irresistibly drawn the attention of medical researchers. A study at Aarhus University, Denmark, found that skin cells in laboratory dishes treated with garlic supplements lived longer, healthier lives than untreated cells (Jrnl Ethnopharm, 1994. 43:125-133).
Meanwhile, a long list of research demonstrates that garlic's phytochemicals may fight tumors and reduce the carcinogenicity of the pollutants and chemicals that assault us daily. A study in China reported in the American Journal of Chinese Medicine showed that garlic helped slow tumors in lab animals (1983, 11:69-73). Another study in the Journal of Nutrition found that compounds in garlic could "suppress the growth of human colon tumor cells" (126, 1355-1361).
Added to those benefits, Robert A. Nagourney, MD, reports in the Journal of Medicinal Food (1:1, 1998, 13-28), garlic may "modify the carcinogenicity of foodstuffs." In other words, studies show that garlic can make chemicals in foods like pork less likely to cause your cells to become cancerous. (Ind J Physiol Pharmacol, 39:347-353).
DNA, the stuff that genes are made of, face constant threats from free radicals, caustic molecules that can alter cellular structure and possibly cause genetic mutations that lead to cancer. But research into what are called oligomeric proanthocyanidins (OPC), flavonoids (pigments) derived from fruits vegetables, grape seed extract and the bark of maritime pine trees shows that OPC may be able to shield DNA from injury.
In particular, studies of a grape seed extract called Activin have demonstrated this substance can help liver cell DNA escape a destructive process called peroxidation (FASEB, 11:3, 2/28/97).
In these experiments, Activin demonstrated the ability to inhibit the growth of tumor cells as well as slow the replication enzymes of HIV viruses. This protective ability proved to be more potent than that of vitamin C, beta carotene and vitamin E.
What does the future promise to reveal? Scientists believe that many unexamined plants probably contain undiscovered phytochemicals that hold great potential for helping us fight the cancer epidemic.
Certainly, if the next few years produce as many results as the past decade, the next millennium will witness a long line of cancer-prevention discoveries. Before long, you should be able to take advantage of these potent substances.
As you gulp your garlic, tip your tea cup, mull your maitake, acquire Activin and await your astragalus, you may meditate on what may soon be added to our growing anti-cancer arsenal. Undoubtedly, scientists with a botanical bent will be uncovering more coveted anti-cancer secrets before too long.
Garlic for the Ages - eat garlic because it's good for your heart...
June 13, 2005 09:58 AM
Garlic for the Ages by Phyllis D. Light, RH Energy Times, January 1 , 2004
If you eat garlic because it's good for your heart, you swallow a plant renowned through human history: Garlic was eaten by Roman soldiers for courage; Egyptian slaves ate it to build strength; Christians, Moslems and Hindus include it in their sacred books. Others have used it as an aphrodisiac, a vampire deterrent and a magical charm.
Garlic has a long history as a culinary and medicinal herb that people either love or hate. Its pungent aroma and warming flavor captivates or repels, but its wealth of natural chemicals does great things for your heart.
Garlic (Allium sativum), a member of the onion family, is native to Siberia but, in modern times, has become a treasured naturalized citizen grown all over the world. Garlic's use in folk medicine dates back about 7,000 years, making it one of the oldest known medicinal foods or herbs.
In modern times, garlic is generally used as a condiment lending a unique, pungent flavor to dishes, but in medieval times, garlic was cooked and eaten as a vegetable in its own right. Today you can revel in a wealth of garlic choices, consuming garlic raw, cooked in various recipes, as a dried concentrated powder, as a fresh liquid extract or as aged garlic powder.
Each little clove of garlic is a powerhouse of good-for-you natural compounds, vitamins and minerals. The biologically active constituents of garlic include allyl sulfur compounds as well as the minerals germanium and selenium.
When you chop up raw garlic and allowed it to stand for about 10 minutes or more, the herb's fragments release an enzyme that converts its compounds from allyl sulfur to another natural chemical called allicin.
Although some allicin is found in garlic before it is cut apart, the yield multiplies considerably when the garlic clove is chopped or pressed and exposed to water (Garlic Conference, Newport Beach, 11/15/98; Penn State).
Many researchers believe that the more allicin produced, the better the health benefits. (Although this is still being debated among the garlic cognoscenti.)
But garlic's benefits don't end meekly on the kitchen counter with its allicin content rising.
Cooked garlic and aged garlic contain other helpful chemicals called diallyl sulphides. Consequently, in any form, garlic produces beneficial health effects.
Fortunately, since raw garlic juice or oil can often irritate the stomach lining, especially in people with sensitive stomachs and delicate digestive systems, garlic supplements and cooked garlic are both helpful for heart health.
Aged Garlic Extract
Aging garlic significantly reduces its irritating compounds and makes it easier on the stomach.
In the aged form, all of garlic's healthy sulfur-containing compounds are converted to water- soluble compounds that retain garlic's natural health benefits. In addition, the pungent odor of the garlic is greatly reduced, an outcome many people desire.
When a group of researchers at Brown University studied the effects of aged garlic extract on people's cholesterol levels, they found that after six months, cholesterol dropped about 6% (Am J Clin Nutr 1996; 64:866-70).
In another study from Brown, researchers found that aged garlic extract reduced platelet adhesion, a sticky blood problem that can cause vessel blockages (New Drug Clin 45(3):456-66). When platelets are less sticky, they are less likely to form blood clots that can cause heart attacks.
Garlic and Heart Disease
A growing body of research shows that a clove of garlic a day can significantly reduce your risk of heart disease.
A four-year study of 280 people who took dried garlic powder three times a day found a striking reduction in the types of arterial plaque blockages that threaten the blood supply to your heart. Interestingly, in this particular study, women displayed a greater reduction in plaque than men (Atherosclerosis 2000; 150:437-8).
Another study found that garlic may also keep important blood vessels more supple and less likely to spasm. Arterial spasms have been linked to heart attacks and other cardiovascular problems in women.
As you age, the aorta, one of the main arteries that carries blood, may harden, reducing blood flow from the heart and placing damaging stress on a number of other bodily organs. In research at Ohio State University, people who took garlic supplements had 15% less aortic stiffness than people who avoided garlic (Circulation).
In this study, scientists found that the older people enjoyed the greatest cardiovascular benefits from daily garlic use.
Researchers believe this extra benefit is linked to the fact that as you age, the endothelial tissue in the linings of the aorta and other blood vessels become less responsive to the need to dilate (expand). As a result, when more blood flow is required, and the heart pumps faster, these vessels take more of a beating from the friction of blood passing through them.
That restriction in dilation has two damaging consequences: In one instance, vessel walls can be injured. In response to these injuries, cholesterol collects on artery walls, plaque forms and the blood supply to the heart muscle can be restricted, leading to a heart attack. In other cases, arteries can restrict blood flow to the heart simply because of the inability to expand sufficiently.
The Ohio State researchers found that arteries in folks aged 70 to 80 benefited the most from taking garlic. But those in their 60s also benefited significantly.
Garlic's natural antioxidant properties can also help protect the heart from damage after surgery (BMC Pharmacology 9/02).
In a study performed on lab animals, researchers found that oxidative stress, a source of cell damage that takes place after surgery, dropped when the animals ate a diet that included garlic.
Oxidative stress can seriously reduce cardiac function, limit the amount of blood the heart can pump and cause permanent damage to the heart muscle.
Garlic Against Blood Clots
Under normal circumstances, blood clots serve a useful purpose: Cut yourself and a blood clot stops the bleeding. Without this clotting ability, you might bleed to death. But if your blood is too prone to clotting, these clumps can cut off blood supply to your heart and other organs, endangering your life.
In a study of apparently healthy individuals whose relatives had already suffered from heart disease, researchers found that their blood formed thick, tangled blood clots, increasing their risk of heart problems (Circulation rapid access 9/23/02). These blood clots are made of a substance called fibrin, a protein in the plasma that can form elastic threads that cut off blood flow.
While these researchers recommended aspirin as an anti-clotting measure for people at risk of heart disease, garlic can also help break up fibrin and possibly lower your chance of heart problems (Pharmatherapy 5(2): 83).
The fibrin that forms clots is produced by blood cells called platelets. Other scientists who have looked into garlic's benefits believe that one of its natural chemicals called ajoene may keep platelets from producing excessive fibrin and gumming up the flow of blood through arteries.
If you've rarely indulged in garlic, you may need a period of adjustment in growing accustomed to its unique taste and aroma. But its heart benefits confirm the long-ago observation by Pliny, an ancient Roman naturalist, that "garlic has powerful properties."
Thanks for the Memory
June 11, 2005 03:49 PM
Thanks for the Memory by Estelle Sobel , February 6, 2002
Thanks for the Memory By Estelle Sobel
"I feel like every day, I lose my memory more and more. It started when I couldn't find my car keys, sometimes I forget directions. My mother has Alzheimer's so I'm concerned," says Jerry Solowitz, a 63 year old man.
Ellen Lerner, 37, sometimes worries that she can't keep track of everything in her job as a public relations executive. "I feel like stress can get to me easily, and I worry because I forget simple things like where I put a file."
Should these people be concerned?
"Yes," says Lynda Toth, Ph.D., co-author with Pavel Yutsis, M.D., of Why Can't I Remember? Reversing Memory Loss (Avery, 1999).
Jerry should start a specific program with a health practitioner who specializes in memory loss, due to lots of unsuspected new causes for memory dysfunction. Ellen needs to make lifestyle changes, as stress can definitely lead to memory loss.
"Cortisol, which is one of the stress hormones, can be harmful because it keeps calcium in the memory pathway too long and destroys the neurons, which is very damaging to the brain," notes Toth.
Why Does Memory Fail?
Memory fails for several reasons, says Augustine DiGiovanna, M.D., author of Human Aging: Biological Perspectives, (McGraw-Hill 2000), and Professor of Biology at Salisbury State University in Salisbury, MD.
Normal Aging: Much of diminished memory as we age is due to reduced blood flow to the brain from atherosclerosis, which is hardening and narrowing of the arteries. Decreased blood flow causes neurons to shrink and function less effectively.
Also, as we age we lose neurons and neuron connections that can lead to memory loss. So the way people think, how much they remember, and the mental activities they do determine how many brain cells survive through the years.
Finally, as people live longer, the chance is greater that the body's immune system and other defense mechanisms won't be able to protect against certain diseases that affect the brain and memory (Parkinson's, strokes, Alzheimers, atherosclerosis).
A Starving Brain: The brain is not getting fed the nutrients it needs (vitamins, minerals, amino acids, glucose). Without the right "food" the brain's energy levels become lowered and stop powering the memory cells. Then, free radicals can do more dirty work and continue to rust memory cells.
Drink And Sink: Alcohol passes through the blood-brain barrier and slows down the processing of information between memory neurons. Memory loss increases over time, as memory tissues shrink.
Sad Stories: Depression can imbalance the neurotransmitters and electrical charges of neurons.
Tense and Tight: High blood pressure can constrict and narrow blood vessels, limiting blood and oxygen flow to the brain.
One way to boost brain power is to take the right supplements.
Ginkgo biloba: The powerful medicinal herb ginkgo biloba increases blood flow and circulation to the head by dilating blood vessels in the brain, allowing more oxygenated blood to get to the neurons. It also protects against free radical damage.
Research: Ginkgo biloba extract displayed a significant effect on helping the mental abilities of people 50-59 years old (Phytotherapy Research 13, 1999: 408-415).
Pregnenolone: This powerful hormone regulates the balance between excitation and inhibition in the nervous system and helps enhance memory and brain function, possibly by repairing a fatty substance that is part of the myelin sheath that surrounds nerve cells. Research: A St. Louis University School of Medicine study on mice showed that pregnenolone enhanced memory and helped mice to navigate mazes better.
Huperzine A: This herbal supplement is derived from club moss found in China; in purified form it inhibits the enzyme that breaks down acetylcholine, a neurotransmitter produced in the brain that you need for memory.
Research: Studies conducted by Alan Mazurek, M.D., found that huperzine A in purified form improves memory, enhances focus and concentration and has been used to improve memory loss in Alzheimer's patients (Alt. Ther. in Health Med. 5 , March 1999: 97-98).
Another study in The Journal of Neuroscience Research showed that huperzine A is a potent inhibitor of cholinesterase, which penetrates the brain and produces a dose-dependent increase of the neurotransmitters acetylcholine, norepinephrine and dopamine in rat cortex (41, 1995: 828-835).
Phosphatidylserine (PS): This substance, which occurs naturally in nerve cell membranes, helps keep fatty substances soluble and cell membranes fluid and helps reduce levels of cortisone which are damaging to tissues.
Research: Phosphatidylserine encourages a sense of calm by raising the levels of alpha brain waves and increasing the production of acetylcholine (Neuropsychobiology 24, 1990-1991: 42-48).
Vitamin E: This potent antioxidant attaches to bad cholesterol and helps prevent free radical damage to cells.
Research: Age-related processes like memory function and problem solving can be affected by free radical damage. Several studies show that vitamin E might slow the effects of Parkinson's disease and Alzheimer's disease (JAMA 282, August 18, 1999: 621). Acetyl-l-carnitine: Increases cognitive performance because it rejuvenates cellular membranes of mitochondria, the storehouses of energy contained in every living cell.
Alpha-Lipoic Acid: Preserves memory tissue by increasing glutathione levels, which protect fat stores in neurons from being damaged.
Nine Ways to Remember
Dr. Lynda Toth suggests the following ways to make the most of what you've now got.
1) Power Up Your Smile. Remove dental fillings and replace them with porcelain or ceramic ones. The mercury in metal fillings may be harmful (some believe) and can affect the brain and nervous system, inflaming memory tissue and preventing the entry of nutrients into the cells.
2) Don't Be a Tin Man/Woman Avoid exposure to aluminum. Don't use aluminum pots to cook in. Aluminum accumulates in memory tissue, damaging cells. In fact, autopsies of Alzheimers patients show they have unusually huge amounts of aluminum in the brain. But no one knows where this aluminum comes from.
3) Eat Right. Eat organic and pesticide-free foods. Pesticides get into the cells and can damage DNA.
4) A Matter of Taste. Avoid foods with artificial coloring, monosodium glutamate (MSG, often called "natural flavors" or "natural seasoning"). Also avoid processed foods with taste enhancers called exito toxins such as l-cysteine and aspartic acid.
5) In the Raw. Make sure that your diet consists of enzyme-rich 50% raw foods (fruits and vegetables) to feed the brain. Eat less animal fats.
* Drink green juices to support levels of the brain's clean-up enzymes.
*Eat lots of fiber, which helps remove toxins from the body. Pick up psyllium fiber.
*Limit intake of processed sugar, caffeine and alcohol to lessen the load on the liver and pancreas.
6) Cut Bait. Watch the fish that you eat. Lots of ocean and inland-caught fish are contaminated with mercury. Go for deep, cold water fish such as cod. Avoid shark and swordfish.
7). Oil Up. Supplement your diet with omega-3 fatty acids, such as cod liver oil or flaxseed oil. These fats lubricate memory cells.
8) Work That Body. Stay fit and exercise. Exercise helps oxygenate the body, reduces cholesterol, and builds and energizes new memory cells which reduces wear and tear on the brain function.
9) Do Mind Games. Read, listen to music. Tune into different radio stations than the ones you normally listen to. Do crossword puzzles and a wide selection of word games which can stretch your brain and give it a tough workout.
Student of Life
You need to keep learning your whole life to keep your brain and memory in tip top shape. The brain is adaptable, and you are always building new neurons, says Dr. Toth, which means that there is no limit to how long it can develop. Anything that stimulates the brain will help it to grow. That's why as you get older it's even more important to take classes, start a new hobby, travel. In fact, the challenge of learning and doing new things (without stopping in a fit of frustration) causes your brain to grow, says Dr. Mazurek.
The Good News
As people get older, their brains may actually improve and repair themselves through a complicated process that is designed to eliminate faulty neurons that are prone to making mistakes. At the same time, brain activity goes on that results in the development of new and improved connections with neighboring neurons.
Research also shows that memory improves if you train people to have faith in themselves. (The brain helps those who help themselves.) Apparently, a confident perspective can encourage the brain to actually improve to the point where its new-found abilities may increase to the point where it fulfills expectations.
So keep your chin up and stay away from the artery-clogging saturated fat that can cut off the brain's blood supply. It's all in the attitude, says Dr. DiGiovanna. And, of course, the key to a long and happy life with your brain is also on the end of your fork and in that bottle of supplements.

Lutein 6mg, 20mg, help stop macular degeneration ...
June 02, 2005 01:39 PM
One of the more surprising discoveries of modern nutritional science is that the very pigments which give brilliant color to our fruits and vegetables are powerful nutrients which can protect us from the rigors of time and environment. Lutein is one of the most recent discoveries in this field. In our diets, it’s found most abundantly in dark green leafy vegetables such as spinach, collards and kale. Like beta-carotene, lutein is a powerful antioxidant which studies show can contribute to the protection of cells. But the most promising application of lutein may be its beneficial influence on the eyes, particularly in regard to macular degeneration. Source Naturals LUTEIN is a concentrated source of this important natural nutrient.
Like the beta-carotene that makes carrots orange and the lycopene that makes tomatoes red, lutein is a carotenoid. It is the pigment that makes corn yellow, and gives marigolds their brilliant golden color. One of the most interesting aspects of the way carotenoids interact with the human body – beyond their broad spectrum antioxidant activity – is their tendency to be “organ specific.” Different carotenoids have an affinity for different organs in the body. In the case of lutein, it is found concentrated in the structure of our eyes.
Vision and Macular Health
The process of vision involves light being focused through the lens and onto the retina, the paper-thin tissue lining the back of the eyeball. The central portion of the retina, called the macula, receives the most light. Its millions of cells produce the sharp vision needed to read and see objects clearly. With age, tiny blood vessels grow over this area, causing a gradual distortion and loss of vision. This degeneration of the macular region of the retina is the leading cause of irreversible visual impairment in the USA today. It affects almost 20% of people past the age of 65. Research has shown that these people have lower than normal amounts of macular pigment, which suggests the protective role played by these pigments. In fact, the latest research suggests that low levels of macular pigment is a cause, rather than a result, of macular deterioration.
Lutein – The Eyes Have It
Lutein and another carotenoid called zeaxanthin are the most dominant pigments in the macular region of the retina. (Source Naturals LUTEIN contains 5-7% zeaxanthin.) Their antioxidant properties help maintain the integrity of the blood vessels that supply the macular region of the retina: providing protection from photo-oxidation, the result of light striking the fatty acids in the retina. It seems that lutein is particularly active against the blue part of the spectrum, which can be the most damaging to our eyes. One study using lutein supplements resulted in a 15% increase in macular pigment levels after 72 days. In another study, people who consumed the equivalent of 6 mg of lutein per day were 40% less likely to experience macular problems. Another study using sets of identical twins demonstrated that macular lutein concentrations were related to dietary lutein. After consumption, lutein is found in significant quantities in blood serum, suggesting high bioavailability.
Our Connection with Plants
In this era of biochemistry, we’re rediscovering our vital connection with plant life. Although research into phytonutrients is relatively new, many plant compounds are being found in significant concentrations in the human body. Their presence in our blood serum, organs, and mothers’ milk suggests they play an important role in our body chemistry, and perhaps explains why we’ve appreciated them as foods throughout history. Like many carotenoids, lutein has evolved as an integral part of human biochemistry, with many benefits to our well-being. Since mammals cannot synthesize it, lutein must be obtained from the diet. Source Naturals LUTEIN is extracted from specially grown marigold flowers high in Lutein, and purified by an exclusive patented process. So the next time you bathe your eyes in a golden bouquet of marigolds, remember their beauty really is in the eye of the beholder.

It's in the BloodNatural alternatives abound for managing cholesterol levels, backed by a growing body of research ©VR By Paul Bubny
The National Cholesterol Education Program (NCEP) last July lowered the threshold for considering the use of statin drugs—a move which some say was motivated more by profits than scientific evidence. For example, the Center for Science in the Public Interest pointed out that eight of the nine authors behind the new recommendations had financial ties to statin manufacturers, which stand to reap billions of dollars more from a category that grossed $14 billion in the U.S. last year. And though the Food and Drug Administration (FDA) in January decided against authorizing over-the-counter (OTC) sales of statin drugs, drug companies would still like to see this happen.
“The medical establishment’s pushing of these drugs to becoming the number one category of prescribed drugs in the world has led them to keep lowering the total cholesterol number that triggers the drug recommendation,” said Neil E. Levin, C.C.N., D.A.N.L.A., nutrition educator, product formulator, and “Truth Advocate” for NOW Foods (Bloomingdale, IL), which produces a number of supplements for addressing cholesterol. “This is despite the lack of evidence that total cholesterol means much as regards cardiovascular risks.
“Other tests are much more important in terms of predicting risks, including CRP (C-reactive protein), the balance of different cholesterol fractions, and homocysteine,” he continued. “Add adult-onset diabetes to the risk factors for cardiovascular disease (CVD).”
At the same time, the allegation that enormous sales potential lay behind the lower threshold for prescribing statin drugs illustrates how widespread the problem of hypercholesterolemia (elevated total cholesterol) is. More than 100 million Americans have elevated cholesterol (total cholesterol values of 200 mg/dl and higher), and of these, more than a third have high cholesterol (levels of 240 mg/dl and higher), according to the American Heart Association. Those numbers have unfavorable implications for the incidence of CVD, as high cholesterol is considered a risk factor for coronary heart disease and stroke.
While statin drugs haven’t garnered the same degree of negative publicity that COX-2 inhibitors have suffered lately, safety concerns have arisen nonetheless. For one thing, these drugs lower the liver’s production of coenzyme Q10 (coQ10) along with its production of cholesterol. “CoQ10 is related to energy production and immune functions, is an antioxidant, and [is] an important cardiovascular nutrient,” Levin said. “It is not good to lower one’s coQ10 levels by half!”
Moreover, said Levin, statins increase the tendency of muscle tissues to break down. “Combined with inactivity or certain drugs, this can stimulate muscle wasting,” he said. “Muscle is where a good deal of calories are burned, so a loss of muscle could affect mobility and energy production, potentially adding to obesity problems. These muscle changes occurred in patients and persisted for years after treatment was discontinued, as shown by muscle biopsies, even if no obvious muscle problems were observed by the patients.”
And the last word on the subject may not have been spoken. Predicted Dr. Frank King, Jr. president of King Bio Natural Medicine (Asheville, NC), “Once the appropriate studies are finished, these drugs, along with hypertensives, will hit the fan bigger than the COX-2 inhibitors.”
Also looking toward the future, Levin said that of the 20 million Americans who will be “targeted” for statin drug prescriptions under the new NCEP guidelines, “Some of these will want to try natural methods first. Others will rebel at the side effects of the drugs and experiment with alternative products.”
King and Levin both saw opportunity for natural products in the fallout from drug safety concerns, with King projecting that sales of his company’s cholesterol-related homeopathic remedies will double in 2005. “The reports of deaths from drugs will always overshadow the trumped-up studies and news reports blasting dietary supplements,” said Levin. “Vioxx knocked vitamin E off the media’s radar screens pretty rapidly, though we still see ignorant reporters citing that [Johns Hopkins] vitamin E analysis as if it were true. But the comparable safety of supplements means that open-minded people will want to at least try natural therapies before signing in to a lifetime of drug therapies. Meanwhile, the studies on natural products will continue to build our credibility.”
Those studies keep coming in, with at least four major findings published in the past few months, plus a heart-health claim on walnuts authorized by FDA. They join a raft of earlier findings that link natural products—branded and otherwise—to healthy cholesterol levels.
"Blur of Products"
With so many natural alternatives to cholesterol drugs available, it can be hard to keep track. “As with any other category, the blur of products as they cascade over several shelves means that the retailer needs to have a good sense of what works and what they want to recommend to their customers,” Levin said. “Really, each person needs a protocol that would include antioxidants, fiber, vitamins, herbs, and oils. The pre-mixed cholesterol support formulas are a good starting place.”
To help retailers get a sense of “what works,” here is an alphabetical discussion of several nutrients that have demonstrated benefits in serum cholesterol levels. They include the following:
Barley may help lower cholesterol, according to a report in the American Journal of Clinical Nutrition (2004, vol.80, no.5: 1185-1193). Twenty-five adults with mild hypercholesterolemia consumed a controlled diet low in total fat, saturated fat, and cholesterol for 19 weeks. They then added whole-grain products containing barley to their diets that contained low (0 g), medium (3 g), or high (6 g) amount of beta-glucan per day for five weeks. Total cholesterol was reduced by 4 percent 9 percent, and 10 percent, respectively. The diet with the highest amount of beta-glucan led to a decrease in LDL cholesterol of 17 percent.
Chromium. There’s evidence, Levin said, that chromium in doses of 500 mg a day may decrease levels of low-density lipoprotein (LDL, the so-called “bad” cholesterol) and total cholesterol while raising levels of high-density lipoprotein (HDL, or “good” cholesterol). At the annual meeting of the American College of Nutrition last October, a poster presentation on the safety of Benicia, CA-based InterHealth Nutraceuticals’ ChromeMate niacin-bound chromium won first prize; among other things, the presentation cited chromium’s role in maintaining healthy blood lipid levels.
Fatty Acids. The latest in a long line of studies demonstrating the benefits of fatty acids in heart health is a study published in The International Journal of Clinical Pharmacology and Therapeutics in December 2004. It showed that docosahexaenoic acid (DHA), an omega-3 fatty acid, can restore normal blood vessel function in children with inherited high cholesterol. The study, which used Martek DHA produced from microalgae, concluded that restoration of normal blood vessel function has the “potential for preventing the progression of early coronary heart disease in high-risk children.”
“The evidence continues to accumulate on the cardiovascular benefits of DHA for people of all ages,” said Henry “Pete” Linsert, Jr., chairman and CEO of Martek Biosciences, an ingredient supplier based in Columbia, MD. “This study clearly indicates that DHA played an important role in healthy blood vessel function in the children in this study.”
On the Omega-Research.com Website maintained by fish oil manufacturer Nordic Naturals (Watsonville, CA) can be found summaries of several earlier studies linking omega-3 fatty acids to maintaining healthy blood lipid levels, as well as related benefits such as elasticity of the arteries. In a 2003 study published in the American Journal of Clinical Nutrition, it was found that women receiving a mixture of 4 g eicosapentaenoic acid (EPA) and DHA along with 2 g of gamma-linolenic acid (GLA) had lower levels of LDL cholesterol after 28 days compared to those who received either the EPA/DHA supplements without DHA, EPA/DHA with a smaller dose of GLA, or GLA alone.
Flax is another source of omega-3s, and Arkopharma/Health From The Sun (Bedford, MA) offers FiProFLAX in a variety of forms. Marketing director Hugues P. Mas said the flax is “QAI [Quality Assurance International] certified organic and guaranteed GMO [genetically modified organism]-free.” On its Website, the company offers a cholesterol quiz geared to consumers, discussing the importance of omega-3s as well as other nutrients.
Garlic. Adding to an already considerable body of research demonstrating that garlic can lower total cholesterol, LDL cholesterol, and triglycerides while increasing HDL cholesterol, researchers at UCLA in 2003 reported that Kyolic aged garlic extract reduced or inhibited plaque formation in the arteries of 19 cardiac patients taking statin drugs.
Lead researcher Matthew Budoff, Ph.D. commented at the time that the study “suggests that aged garlic extract may be a useful and beneficial dietary addition for the people who have high cardiovascular risk or who have undergone heart surgery.” Budoff has since presented several trade show seminars sponsored by Los Angeles-based Wakunaga of America, the makers of Kyolic.
Guggul. In use for centuries as a component of Ayurvedic medicine, guggul—a gummy resin tapped from the Commiphora mukul tree, which is native to India—has been studied since the early 1960s for its hypolidemic (blood-lipid lowering) properties. Sabinsa Corp. (Piscataway, NJ), an ingredient supplier which produces a standardized extract under the brand name Gugulipid, says the studies on guggul indicate that its hypolipidemic activity can be attributed to more than one mechanism of action.
Among the possible mechanisms are: inhibition of cholesterol biosynthesis, enhancing the rate of excretion of cholesterol, promoting rapid degradation of cholesterol, thyroid stimulation, alteration of biogenic amines, and “high affinity binding and anion exchange.”
Homeopathy. “Homeopathy activates the body’s own control system to work properly,” said King. “This is the safest and most curative approach to take.
“Forcing the body into biochemical change even naturally doesn’t actually have the curative action of homeopathy,” King continued. “Homeopathy can even correct the genetic predispositions to disease we may have inherited from as deep as a thousand years into our family chain.” King Bio makes Artery/Cholesterol/BP, a homeopathic formula intended to help tone heart muscles and blood vessels.
Low glycemic index foods. In a study published in the February issue of the American Journal of Clinical Nutrition, researchers found that high glycemic load is negatively correlated to serum levels of HDL cholesterol. Assessing the relationship between blood levels of lipids and diet in a test population of 32 healthy males and females ages 11 to 25, the researchers found that glycemic load accounted for 21.1 percent of the variation in HDL cholesterol. They concluded that glycemic load appears to be an important independent predictor of HDL cholesterol in youth and noted that dietary restrictions without attention to glycemic load could unfavorably influence blood lipids.
Medicinal Mushrooms. Although its product SX-Fraction is intended primarily to address high blood sugar, Maitake Products, Inc. (MPI, Ridgefield Park, NJ) found in a clinical study that LDL cholesterol in diabetic patients declined modestly (from 142 mg/dl to 133 mg/dl) over a two-month period. Those taking SX-Fraction also lost about 7 lbs. in the same time period.
“The more impressive lowering of cholesterol, however, comes from the dietary fiber that is found in all medicinal mushrooms,” said Ellen Shnidman, manager of scientific affairs at MPI. She cited animal studies which documented the cholesterol-lowering properties of four different mushrooms: maitake, shiitake, agaricus, and enokitake.
For example, a study reported in the September 1996 issue of Alternative Therapies showed “a 44 percent reduction in total cholesterol in rats consuming maitake mushroom in their diet,” said Shnidman. “This cholesterol reduction is accompanied by weight loss, relative to rats eating a similar high-choelsterol diet without mushrooms. Apparently, cholesterol is excreted by the rats in sufficient quantity to aid in weight loss.”
Oat bran. A 2004 consumer study conducted by the Natural Marketing Institute (NMI, Harleysville, PA) for Nurture, Inc. (Devon, PA), which produces the ingredient OatVantage, found that 63 percent of consumers managing their cholesterol levels prefer oat-based ingredients.
Oat bran is the subject of a health claim authorized by FDA in 1999, and NMI research found that 69 percent of respondents preferred the FDA-permitted health claim, “Helps Lower Cholesterol,” over the model structure-function claim, “Helps Maintain Healthy Cholesterol Levels.” “This is significant for food, beverage, and dietary supplement manufacturers who want to increase sales by using a more consumer-desired claim on the product label,” said Griff Parker, Nurture CEO.
Plant sterols. Also the subject of an FDA-approved claim for heart health, plant sterols (structurally similar to cholesterol in humans) can block the absorption of cholesterol, according to a number of studies. In an “Ask the Doctor” publication (available online at www.atdonline.org), Decker Weiss, N.M.D. noted that sterols enter the same receptor sites that cholesterol enters on its way to the bloodstream. “The cholesterol, being blocked from absorption, remains in our intestines where it is eventually excreted,” Weiss wrote. General Mills has just introduced Yoplait Healthy Heart, a yogurt high in plant sterols.
Policosanol. A mixture of fatty alcohols derived from sugar cane or beeswax, policosanol has been favorably compared in clinical studies to several types of prescription drugs for managing cholesterol. On its own, policosanol was found in a 1999 study to reduce LDL cholesterol while raising levels of HDL cholesterol.
Probiotics. “Several studies have indicated that consumption of certain cultured dairy products resulted in reduction of serum cholesterol, as well as triglycerides,” wrote Dr. S.K. Dash, president of probiotic manufacturer UAS Laboratories (Eden Prairie, MN), in his Consumer Guide to Probiotics. Among other studies, Dash cited two controlled clinical studies from the VA Medical Center at the University of Kentucky.
“In the first study, fermented milk containing [Lactobacillus] acidophilus was accompanied by a 2.4 percent reduction of serum cholesterol concentration,” he wrote. “In the second study, a different L. acidophilus strain reduced serum cholesterol concentration by 3.2 percent. Since every 1 percent reduction in serum cholesterol concentration is associated with an estimated 2 to 3 percent reduction in risk for coronary heart disease [CHD], regular intake of fermented milk containing an appropriate strain of L. acidophilus has the potential of reducing risk for [CHD] by 6 to 10 percent.”
Dash said his company’s DDS Probiotics contain DDS-1 L. acidophilus, “which has been researched and demonstrated to show cholesterol-lowering effect.”
Psyllium. “Internal cleansing is very important” in maintaining healthy cholesterol levels, “especially if you do it with a lot of fiber,” said Sunil Kohli, vice president of Chino, CA-based Health Plus, Inc. The cholesterol-managing ability of fiber in general and psyllium in particular is “very well-established,” he said.
However, Kohli said, “It will probably do you no good if it’s random. It should be done on a regular basis, and it should be supervised. Consulting the doctor or pharmacist is important.”
Soy. The protein in soy “has evidence of lowering total cholesterol and LDL cholesterol, based on reviews of studies using over 20 g of soy protein per day,” said Levin. “Soy isoflavones are considered only partly responsible for this effect.”
Sytrinol. A patented proprietary formula derived from natural citrus and palm fruit extracts and containing citrus polymethoxylated flavones and palm tocotrienols, Sytrinol has been shown in clinical trials to improve total cholesterol, LDL cholesterol, and triglycerides by up to 30 percent, 27 percent, and 33 percent, respectively. Having just wrapped up Phase III of a long-term trial of Sytrinol, Chicago-based SourceOne Global Partners, which owns the exclusive worldwide license for intellectual property associated with the ingredient, is commencing a study that combines Sytrinol with plant sterols.
Tocotrienols. On its Website discussing the science and benefits of tocotrienols (www.tocotrienol.org), ingredient supplier Carotech Inc. (Edison, NJ) identifies several benefits for blood lipid levels. Tocotrienols, according to the Website, have been shown to “inhibit cholesterol production in the liver, thereby lowering total blood cholesterol;” “[suppress] hepatic HMG-CoA reductase activity [and result in] the lowering of LDL cholesterol levels;” and “inhibit cholesterogenesis by suppressing HMG-CoA reductase.”
There are also nutrients that are emerging as potential weapons in the fight against cholesterol. Levin cited rice bran oil, resveratrol, pantethine, l-carnitine, and niacin as showing promise.
With all of this, Levin said, it’s important for retailers to remember that “they are not allowed to discuss diseases and remedies unless there is an approved FDA health claim allowed on the label, as with soy protein and plant sterols. What is allowed are structure-function claims such as ‘cholesterol support,’ ‘promoting normal, healthy circulation,’ ‘homocysteine regulators,’ etc.”
Supplementation is only one tool for managing cholesterol levels, manufacturers pointed out. “Besides nutrition, lifestyle is a key to controlling cholesterol,” Levin said. “Eating a variety of antioxidant-rich foods will prevent the liver from churning out cholesterol as a ‘cheap’ antioxidant. The body uses oxidized cholesterol to patch leaky and damaged blood vessels, so the ability to build healthy collagen is a must, using nutrients like vitamin C, Pycnogenol, rutin, hyaluronic acid, and MSM.
“Don’t forget exercise and stress reduction,” he added. “Stress results in high cortisol levels—usually accompanied by poor blood lipid levels—and a lack of good sleep to produce unhealthy people.” VR
