Essential Oils Is Flax Seed
January 30, 2014 05:58 PM
Flax Seed as an Essential Oil
A rich source of recuperating mixes, flax seed has been grown for more than 7000 years. Initially grown in Europe, the plant's tan seeds were customarily used to plan salves for aggravated skin and mending slurries for stoppage. Rich in essential oils, or EFAs, flax seed oil is utilized to anticipate and treat coronary illness and to assuage a mixture of incendiary issue and hormone-related issues, incorporating fruitlessness.
Flax Seed History
A source of filament for cloth fabric since aged times, the slim flax plant likewise brags a long history as a mending herb. Initially grown in Europe, the plant's tan seeds were customarily used to plan salves for aroused skin and mending slurries for clogging. Today, flax seeds (additionally called linseeds) are best known for the helpful oil that is inferred by pressing them. Rich in essential greasy acids, or EFAs, flax seed oil has earned a robust notoriety for treating a reach of afflictions, from coronary illness to lupus.
Benefits of Flax Seed Oil
The essential oils and greasy acids in flaxseed oil are one of its key mending parts. EFAs are especially profitable in light of the fact that the form needs them to capacity fittingly, yet can't produce them on its own. Essential greasy acids work all around the form to secure cell layers, keeping them effective at conceding solid substances while excepting harming ones.
One of the EFAs in flax seed oil, alpha-linolenic harsh corrosive, is reputed to be an omega-3 greasy harsh corrosive. Like the omega-3s found in fish, it seems to diminish the danger of coronary illness and various different illnesses.
Flax Seed Oil is an Amazing Source of Omega 3:
Just 1 teaspoon holds around the range of 2.5 grams, identical to more than double the sum most individuals get past their eating methodologies. Flax seeds additionally hold omega-6 fattening acids as linoleic harsh corrosive; omega-6s are the same solid fats found in vegetable oils.
Flax seed oil just holds these alpha-linolenic harsh corrosive (Omega 3 oils), and not the strand or lignan segments. Along these lines, flax seed oil gives the Omega 3 profits, for example, lipid-bringing down lands, not the purgative or against growth lands.
Entire flax seeds (not the concentrated oil) are a rich source of lignans (phytoestrogens), substances that seem to emphatically influence hormone-related issues. Lignans might likewise be functional in anticipating certain growths and battling particular microscopic organisms, parasites, and infections, incorporating those that cause mouth blisters and shingles.
Facts about whey protein.
January 24, 2014 10:09 AM
Whey protein refers to one of the two significant parts of milk, whey is the fluid parcel of the milk that divides from the curds (the other real part), throughout the process of cheese processing. Whey proteins are made up of fats, sugars, vitamins, and minerals. Because of its tough amino acid acerbic profile and simplicity of withholding, it is ostensibly the most prominent games nourishment supplement.
Whey protein exists in three principle structures:
Isolate, concentrate, and hydrolysate. This article will concentrate on how different is concentrate from isolate. Both structures have whey protein, but whey isolate, which is created out of whey concentrate, goes through further processing which yields an end product with more protein per unit than whey concentrate.
Then again, the whey protein isolation procedure is significantly more exhaustive. It basically differentiates the protein, just about in its sum from the crude whey, bringing about 90-94% pure protein. So in a 50-gram serving of whey protein isolate, move toward getting 45-47 grams of unadulterated protein with the remaining 3-5 grams being maybe 1 gram of crabs and some calcium, potassium and sodium.
You may tend to think that whey protein is spring water because as it is separated, pure and also healthy, yet contains the greater part of the minerals and so forth of regular water. While whey protein disengage is like refined water, as it is water in its purest structure with essentially all different particles evacuated additionally a hydrogen and oxygen atom
The essential distinction between isolate and concentrate
Isolate is the most unmodified type of protein. Whey isolate typically have between 90-94% proteins while whey concentrate has a protein proportion of around 70-85%.
In the event that you are you are not fit for lactose and you have issues with gas then the whey protein isolate is the better decision. Whey protein concentrate is also an astounding source of protein and concentrate has higher BV qualities contrasted with lean red meats, chicken, fish and entire eggs. Isolate whey is more expensive than other forms as Isolate has been filtered more than concentrate some of the important immune-boosting protein components have been removed and some say the protein is degraded more making it less useful to the body.
The following sites have more on whey proteins that every consumer should know.
Why Do We Need Essential Fatty Acids (EFA's) And What Source Is Best?
February 15, 2011 05:03 PM
EFA's can boost Your Health
Essential fatty acids are organic compounds that the human body necessitates to support healthy functions of organs and tissues but lack the ability to synthesize. Two fatty acids make up this group: (1) alpha linolenic acid, or ALA, and (2) linoleic acid, LA. Also referred to as EFAs, they are ubiquitous at the cellular level, but known to play an active role in neuronal and vascular tissues as well as in inflammation.
Maintains Cellular Health
One of the most recent advancements in cellular science is the discovery of lipid rafts, which are a part of the bilipid layer of cell membranes specialized for trafficking of cellular molecules, such as proteins and receptors. Also, these lipid rafts have an effect on the viscosity of cell membranes, thereby influencing fluidity that governs membrane-dependent functions of cells such as cellular signaling and phagocytosis, the mechanism by which cells swallow extracellular debris including pathogenic stimuli. Due to its being less stiff and more fluid, essential fatty acids make up cell membranes.
Modulates Neuronal Activities
It has long been postulated that learning and memory is influenced by the availability of intracellular substances known as endocannabinoids in a process called retrograde signaling. Unlike other neurotransmitters, endocannabinoids act on presynaptic cells while produced in postsynaptic cells, and by so doing enhances the signal transmission between nerve cells. Essential fatty acids are converted into endocannabinoids, which are produced on demand, and thus daily intake of EFA is a must. In addition, EFA has for years been in use as a treatment for depression and in the prevention of neurodegenerative diseases.
Regulates Inflammatory Responses
The right amounts of essential fatty acids present inside the human body significantly contribute to the inflammatory responses of the immune system. There are chemical compounds that are produced by the body only in the presence of essential fatty acids, and a number of these compounds are essential to the process of healing and other processes implicated during inflammation. This is the reason why intake of EFA is highly regarded as a therapeutic remedy for reducing inflammatory diseases such as arthritis and autoimmune illnesses.
Promotes Cardiovascular Health
There is high risk of heart attack and related cardiovascular diseases in populations with low levels of essential fatty acids. Especially for individuals who are dependent on drugs that are known to cause oxidative stress in vascular tissues, susceptibility to damages of the blood vessel linings sets the stage for the buildup of macrophages and bad cholesterol in the form of arterial plaques. These plaques contribute to the thinning of the vascular passageways characteristic of atherosclerosis.
There is a reason why alpha linolenic acid and linoleic acid are considered essential fatty acids. They are a vital component of a healthy body with well-functioning organs and tissues. Good thing we have a wide list of food sources rich in EFA, which includes the oils of hemp, soya, canola, and wheat germ. EFA is also abundant in seeds of sunflower, chia, pumpkin, and flax.
EFA's should be an essential part of everyone's diet, have you had your EFA's today?
December 23, 2008 11:44 AM
Although it is important to stress that the fatty acids found in flax are essential, flax also contains substances called lignans. Lignans are special compounds that demonstrate impressive health benefits, as they seem to be responsible for assisting the immune system in many ways, along with helping to prevent some types of cancers.
Because flax contains lignans, it is an even more beneficial to the body when consumed in this form. Flax is one of the most abundant sources of lignans, a type of phytoestrogen that interferes with estrogen metabolism in animals and humans. This property gives lignans the ability to help in the prevention of both fat and hormone-sensitive types of cancer. Lignans also benefit the body by providing antibacterial, antifungal, and antiviral activity that helps the immune system to function optimally.
All of the benefits of flax are still yet to be known, but it has been established that flax is also a good source of fiber. There have been several studies which confirm that flaxseed can be a cholesterol-lowering agent similar to oat bran, fruit pectin, and other food ingredients that contain fiber. Because flax packages both omega-3 fatty acids and soluble fiber together, it presents two ingredients which provide healthy blood lipid patterns. Flaxseed contains beneficial amounts of both soluble and insoluble fiber, giving it potential cancer-fighting ability especially in colon cancer.
When selecting a healthy diet, it is important to consider your sources of essential fatty acids. Essential fatty acids are fragile and easily damaged by air, high temperatures, and food processing, so you are unlikely to get all of the EFAs that you need, even if you are careful to use vegetable oils for cooking. Most of the oil that we consume today has been heavily processed, which damages essential fatty acids. When choosing flax oil, you’ll want to take into account the same considerations, looking for oil that has not been damaged by processing and is packaged to block all light from contact with the oil.
Not all flax oils are the same, with there being a great deal of variation in quality and purity as a result in differences of how the oil is expressed. Most flaxseed oils are mechanically pressed out through an expeller, in which great amounts of heat and pressure can be generated. The higher the temperature, the better the yield of oil, but the lower the quality of oil. Many manufactures willingly sacrifice quality for quantity. The best way to measure the quality of oil is by taste, with the degree of bitterness being a close approximation of the level of lipid peroxides. The best source of high quality flaxseed oil can be found in health food stores where inventory turnover is highest.
Some good guidelines to go by in selecting a good flaxseed oil include: making sure the flaxseed oil is derived from 100% certified organic flaxseed; making sure the oil is as fresh as possible and not past the expiration date; making sure that the oil is expeller-pressed or cold pressed; using flaxseed oil that is high in lignans to gain the most benefit.
EFA's - Essential Fatty Acids
September 15, 2008 09:42 AM
Many recent studies have found that EFAs may be extremely helpful for many chronic, stubborn conditions. Their continuously growing range of applications includes overcoming diseases such as alcoholism, breast cancer, and cardiovascular disease; strengthening the immune system; helping eliminate yeast infection; reducing symptoms of premenstrual syndrome; minimizing inflammation of rheumatoid arthritis; and assisting in the proper management of weight.
Alcohol dependence is an extremely serious condition that often results in decreased life expectancy, suicide, degeneration of the brain and liver, osteoporosis, and many other conditions. For each person, the rate at which alcohol is metabolized in the body is different, as a lot of it has to do with the person's nutritional status, the concentration and activity of liver enzymes, and the rate at which alcohol is consumed.
Alcoholics tend not to eat because the calories from alcohol, although nutrient-poor, diminish the appetite, causing many alcoholics to become extremely malnourished. An overall nutritional program should be employed to those people who are dependant on alcohol, which should include vitamins A, C, and B, complex, along with zinc, magnesium, selenium, amino acids, milk thistle, acidophilus, antioxidants, L-carnitine, and essential fatty acids. EFAs, especially those that are high in GLA, keep blood lipid levels from going out of control.
The body's immune system has a vital role in protecting us against cancer, as it recognizes and annihilates any abnormal cells before they have the chance to multiply and do damage. When the immune system is overwhelmed or not functioning properly, abnormal cells will reproduce without having anything to stop them. Because of the rapidly growing tumors which have a huge appetite for nutrition to keep them going, cancer patients often become malnourished and lose weight. A diet that is rich in cruciferous vegetables, fiber, antioxidants, vitamins A, C, and E, minerals, and essential fatty acids can help prevent breast cancer. Research shows that EFAs, especially GLA, have anti-tumor properties.
All of the cells in the body have a dependence on nutrients that are transported through the circulatory network. When blood vessels become clogged with fats and cholesterol, nutrition distribution is hindered and blood flow can be stopped in some areas, causing the heart to die. Exercise is a good for increasing circulation and keeping the blood from getting stuck. A diet that is high fruits, vegetables, natural fiber, and low in saturated fats, meats, and homogenized dairy products is also a good idea. Additionally, antioxidants, hawthorn berry, ginkgo biloba, vitamin E, Co Q-10, L-carnitine, calcium, magnesium, potassium, and EFAs will also be of benefit to the cardiovascular system.
Essential fatty acids have been shown to stop the growth of yeast organisms in the body. They do so by helping the oxygen to flow to cells. Since yeast is anaerobic, it cannot thrive in the presence of oxygen. Yeast overgrowth can cause a variety of symptoms that are often diagnosed as another condition, ranging from joint swelling to memory loss.
PMS is a collection of symptoms that occurs one to two weeks before menstruation, affects about one-third of women who are younger than forty. It is caused by hormone imbalances, which result in anxiety, irritability, and mental sluggishness. Research has found that women with PMS usually eat more refined carbohydrates, dairy products, and sodium, and less iron and other minerals than those women who do not experience this condition. Vitamin B complex, beta carotene, vitamin E, magnesium, milk thistle, acidophilus, and essential fatty acids are very helpful for PMS. Essential fatty acids, especially GLA, are helpful in balancing the body's hormone levels.
Reducing symptoms of disease like arthritis or PMS is important to all those who suffer from them. EFA's can help reduce the symptoms of these diseases. American diets are low in EFA's and one should consume them either in the foods they eat or supplement form to help the body strengthen its self and fight off disease.
Flax Seed Oil
August 07, 2008 01:53 PM
Flax seed naturally contains a variety of different categories of essential fatty acids, which includes alpha linoleic acid, linoleic acid, and omega-9 oleic acid. A lot of flax seed’s benefits are a function of its content of alpha linoleic acid, which is converted in the body to a longer chain of omega-3 EPA. Research has proven that supplementation with flax seed oil can help to increase the EPA concentrations in many tissues of the body. One of the main areas of research has been inflammation.
Many factors contribute to inflammatory reactions, including omega-6 linoleic acid, which can be converted into pro-inflammatory substances. Flax alpha linoleic acid can convert into EPA, which has the ability to convert into a prostaglandin that has anti-inflammatory properties. In inflammatory states, alpha linoleic acid and EPA compete with linoleic acid for enzymatic metabolism, resulting in a decreased production of pro-inflammatory substances. Many studies have found that the use of flax seed oil in domestic food preparation can reduce the production of inflammatory cytokines.
These studies have also shown the ability of omega-3 rich fish oils to inhibit inflammatory mechanisms in the autoimmune disease lupus nephritis, which lead to the investigation into flax having any abilities in this area. One trial found that 30g/d of flax seed was optimal for improving kidney function, decreasing inflammation, and reducing atherosclerotic development. Flax also contains antioxidants, which may be helpful to those who have SLE.
Research has also been conducted to investigate the hormonal modulating effects of ingesting lignans, which are antioxidant and phyto-estrogenic compounds that are found in flax seed. Clinical evidence indicates that phytoestrogens have an anti-cancer effect on the breast. Experimental studies in animals and humans have also demonstrated flax’s anti-cancer effects, with a 1998 review indicating that the consumption of flax may be used as a secondary prevention method against breast cancer. Flax seed has also been shown to promote prostate health, as it plays a key role in the treatment of an enlarged prostate.
The cardiovascular system is also another area of research focus for flax seed. One study showed that three months of flax seed supplementation resulted in LDL cholesterol levels dropping significantly, while HDL cholesterol did not change. Other research has shown serum lipid level reduction, but a large amount of flax seed was required to be consumed to get the same lipid-lowering effects as fish oils. Flax lignans also possess anti-platelet activating factor activity and antioxidant activity. Animal research has shown that flax seed reduced the development of aortic atherosclerosis’ by 46 percent and suppressed oxygen-free radicals.
The research concluded that dietary flax seed supplementation could prevent hypercholesterolemia-related heart attack and strokes. Lastly, the elasticity of arteries is an important factor of circulatory function, which decreases as the cardiovascular risk increases. Research has proven that obese people consuming a diet high in ALA from flax seed oil experience a marked rise in arterial elasticity, which reflects a rapid improvement in the arterial circulation.
Although flax seed offers many potential benefits, ingesting the right form of supplemental flax is crucial to gaining these benefits. Flax oil supplements are a good source of EFAs, but they do not provide great amounts of lignans. On the other hand, whole or ground flax seed is effective, but is not especially palatable. The best option of flax seed is the liquid in capsule form, as it delivers both EFAs and lignans. The nutritional value and certain beneficial results can be gained by consuming about 3,000 mg daily.

Acai, one of the latest, hot new health food discoveries from the Amazon rainforest boasts some impressive credentials as a source of omega-6 and omega-9 fatty acids, vitamins A, C and E and more than 50 other antioxidants, especially anthocyanin—the powerhouse pigment found in red wine and blueberries.
Proponents of acai, which is actually the purplish fruit of Euterpe oleracea, a short palm found in abundance in Brazil, claim this superfood promotes healthy cholesterol, supports the immune system and protects the heart. With the publication of a new study in the Journal of Agricultural and Food Chemistry, they might be able to add “fights cancer” to that list as well.
The study, conducted at the University of Florida, tested the effect of pure acai juice-stripped of any lipids (EFAs) and cellulose material on HL-60 human leukemia cells in vitro. Researchers also evaluated five other extracts or “fractions” of the fruit, which contained different mixtures of antioxidants, for their effect on leukemia cells. They found that the extracts "reduce cell proliferation from 56% to 86%, most likely by damaging the cells enough to cause them to self-destruct."

Omega-3’s Fight Postpartum depression
January 23, 2006 02:42 PM
Omega-3’s Fight Postpartum depression
Tucson, AZ—Marine-sourced omega-3 essential fatty acids (N-3 EFAs) combat postpartum depression (PPD), according to a study published online in acta Psychiatrica Scandinavia (www.blackwell-synergy.com).
In the eight-week trial, test subjects were randomized to receive 0.5 g/d (n-6), 1.4 g/d (N-3) or 2.8 g/d (n-7) n-3 EFAs (as EPAX omega-3 oil provided by Epax AS, Previously a division of Pronova Biocare AS [www.provona.com]). All groups had reductions in mean scores on Edinburgh Postnatal and Hamilton Rating depression scales (51.5 percent and 48.8 percent, respectively); changes from baseline were significant within each group and when combining groups. The researchers concluded results of the study support further study of n-3 fatty acids as a treatment for PPD.
“Omega-3 fatty acids were assessed in a double-blind dose-ranging trial,” said Marlene Freeman, M.D., director of the Women’s Mental Health Program and assistant professor of Psychiatry, Obstetrics & Gynecology, and Nutritional Sciences at the University of Arizona College of Medicine. “A combination of omega-3 EPA and DHA fatty acids provided by EPAX AS was utilized. Among all three doses, patients with postpartum depression improved substantially during the trial. Scores on depression measures decreased by approximately 50 percent and differences were statistically significant.”
Sources of Essential Fatty Acids
June 25, 2005 08:38 PM
Sources of Essential Fatty Acids
Essential fatty acids are found in both plant and animal sources, although primarily in plants. The EFA family is composed of two main forms, Omega-3 and Omega-6. The following explains exactly what these forms are.
OMEGA-3: The most common forms of Omega-3 are eicosapentaenioic acid (EPA), docosahexaenoic acid (DHA) and alpha-linolenic acid, which comes from plants and helps create EPA and DHA. Omega-3 is usually derived from fish oils. Dr. Roger Illingworth, associate professor of medicine and biochemistry at Oregon Health Sciences University, explains that Omega-3 fatty acids are “long-chained metabolic products from linolenic acid. . . When animals consume and metabolize plants rich in linolenic acid, they produce Omega-3.” EPA and DHA are liquid and remain that way, even at room temperature. It is said that they protect fish by providing a body fat that stays fluid even in cold temperatures. OMEGA-6: The most common form of Omega-6 is is gammalinolenic acid (GLA). GLA is known to provide the following benefits, among many others:
Omega-6 is usually found in plant sources. The oils of coldwater fish such as salmon, bluefish, herring, tuna, mackerel and similar fish are known as Omega-3 fatty acids. The freshpressed oils of many raw seeds and nuts contain Omega-6 fatty acids. The most popular sources of Omega-3 and Omega-6 include:
BLACK CURRANT SEED OIL: This oil is rich in linoleic acid (44%) and provides almost twice as much gamma-linolenic acid as evening primrose oil. Black currant seed oil also is an excellent source of an Omega-3 precursor known as stearidonic acid. BORAGE OIL: This oil comes from Borago officinalis, a plant with blue flowers. It is widely recommended in Europe to strengthen the adrenal glands, alleviate symptoms of premenstrual syndrome and relieve inflammation. Besides possibly helping with heart and joint function, it may also assist the growth of nails and hair. Borage oil is also an excellent source of GLA. In The Complete Medicinal Herbal, herbalist Penelope Ody asserts that it is “helpful in some cases of menstrual irregularity, for irritable bowel syndrome, or as emergency first aid for hangovers.” SALMON OIL: This oil is high in Omega-3 essential fatty acids. These types of EFAs are known to thin the blood, prevent clotting, regulate cholesterol production and strengthen cell walls, making them less susceptible to viral and bacterial invasion. Salmon oil has a natural ability to help the body relieve inflammation. In the ground-breaking book The Omega-3 Breakthrough: The Revolutionary, Medically Proven Fish Oil Diet, professor Roger Illingworth writes that Linolenic acid is a fatty acid with 18 carbons and 3 double bonds.
It is manufactured exclusively by plants. When animals consume and metabolize plants rich in linolenic acid, they produce Omega- 3. Plankton, a minute form of marine life, is part plant and part animal. Its plant component manufactures linolenic acid. Fish eat the plankton, and the linolenic acid breaks down in their bodies in two types of Omega-3 fatty acids: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) . . . The liquidity of EPA and DHA serves a vital function in fish, who require body fat that remains fluid even in very cold water. Fish oils, besides containing Omega-3 fatty acids, have shown to benefit those suffering from migraine headaches, arthritis, and high cholesterol levels.
FLAX: Flax is a plant said to date back as far as 5000 B.C. It has been used since approximately 5000 B.C., making it one of the oldest cultivated crops. It is exported from several countries, including Argentina, Canada, India, Russia and the United States. The flowers are usually blue, although they are sometimes white or pink. The mucilaginous seed is, of course, called flaxseed. The oil primarily provides Omega-3/linolenic acid, and provides an average of 57 percent Omega-3, 16 percent Omega-6, and 18 percent of the non-essential Omega-9. Flaxseed oil is said to contain rich amounts of beta carotene (about 4,300 IU per tablespoon) and vitamin E (about 15 IU per tablespoon). In the October 1995 issue of Let’s Live, the history and uses of flax were highlighted by herbalist Carla Cassata. She writes, . . . It’s no wonder the Cherokee Indians highly valued the flax plant. They mixed flaxseed oil with either goat or moose milk, honey and cooked pumpkin to nourish pregnant and nursing mothers, providing them with the needed nutrients for creating strong and healthy children. It was also given to people who had skin diseases, arthritis, malnutrition as well as men wishing to increase virility. They believed flax captured energies from the sun that could then be released and used in the body’s metabolic process.
This belief has merit. Flaxseed oil, rich in electrons, strongly attracts photons from sunlight. To be effective, EFAs must be combined with protein at the same meal. This flaxseed oil/protein/ sunlight combination releases energy and enhances the body’s electrical system. Also, this combination, along with vitamin E, can be beneficial for infertile couples and women suffering from premenstrual syndrome . . . Flaxseed oil, having an anti-inflammatory effect on the body, can benefit the 40 million Americans suffering from osteoarthritis and rheumatoid arthritis. To achieve optimum results, however, substances that activate the sympathetic nervous system—like refined sugar, soda, coffee, fluoride— must be eliminated. Stress must also be reduced, because it too, activates the sympathetic nervous system, promoting inflammation.
EVENING PRIMROSE: This flower is indigenous to North America, although the oil is particularly popular throughout Europe for therapeutic purposes. It is also known as night wil - low and evening star. It is an excellent source of both linolenic and linoleic acids. Both of these nutrients must be obtained from the diet, as the body cannot synthesize them. The seeds contain gamma linolenic acid. This polyunsaturated EFA helps with the production of energy and is a structural component of the brain, bone marrow, muscles and cell membranes. Evening primrose oil has also benefited those with multiple sclerosis, PMS, hyperactivity and obesity. It is estimated that it takes about 5,000 seeds to produce the oil for one 500 mg capsule.
Benefits and Functions of Essential Fatty Acids
June 25, 2005 08:29 PM
Benefits and Functions of Essential Fatty Acids
The body takes combinations of different triglycerides and makes fats from them to help in various processes. The basic building blocks of any fats are the fatty acids. Fatty acids are either essential or nonessential. A fatty acid is considered essential if 1) the body is unable to synthesize it and 2) the only way it can be obtained is through the diet. In addition, it is considered essential if a deficiency will cause a disease. As far back as 1930 researchers discovered that if an animal did not get essential fatty acids in the diet, it could cause symptoms such as poor reproduction, lowered immunity, rough, dry skin, and slow growth, among others. There are basically three essential fatty acids. They are linoleic acid, linolenic acid, and arachidonic acid. Linoleic acid is the most vital. Linolenic and arachidonic acids can be converted from linoleic acid, but linoleic acid must be obtained from the diet. Most people are unaware of the many vital functions of essential fatty acids. The list includes:
Cholesterol is synthesized throughout the body. It is manufactured by cells, glands, the small intestine and the liver. Cholesterol is constructed from dietary by-products of proteins, sugars and fats. If the diet contains excessive fats, especially the saturated types, the body will convert them into cholesterol. People who eat high sugar or fat diets may therefore experience elevated cholesterol levels.
Prostaglandins are found in almost all body cells, and act as catalysts for many physiological processes. They help prevent abnormal blood clotting and nerve inflammation. Prostaglandins also help promote blood circulation by dilating the blood vessels and improve immune system function. The most beneficial type of prostaglandin is called PGE-1. PGE-1 balances cholesterol and blood pressure levels, and stimulates the body’s production of T-lymphocytes which strengthen the immune capabilities. Each cell keeps tiny amounts of EFAs and produces prostaglandins from them as they are needed. The name prostaglandins was coined because these substances were originally found in high amounts in the prostate gland. To date, there have been discovered at least thirty-six different prostaglandins with a wide range of roles in the body.
Essential Fatty Acids - The “Good” Fats
June 25, 2005 08:24 PM
All About Fats
Some people shy away from anything that has the word “fatty” associated with it. They instantly think it will cause them to gain unnecessary weight. However, there are “good fats” and “bad fats,” and the beneficial ones can actually help decrease the desire to eat the harmful ones. Fats are important for health. Also known as lipids, they help balance the body’s chemistry and provide padding as protection for vital organs. Fats provide a source of energy for body processes, and they help with the transportation and absorption of fat-soluble vitamins such as A, D, E, and K. They are also a source of the vital nutrients known as essential fatty acids. Categories of fats include the following:
SATURATED FATS: All fats are composed of carbon, hydrogen, and oxygen molecules. The carbon atoms of fatty acids hold together in a chain-like fashion. These carbon atoms can attach hydrogen to them. When each place that can hold a hydrogen atom is filled and there is not room for even one more, they are described as saturated. The longer the chain, the harder the fat will be and thus, the higher its melting point. These types of long-chain fatty acids are found in “hard fats,” such as those in red meat, butter, cheese, sour cream and palm kernel and coconut oils. When a person’s diet is high in saturated fats, these fats tend to clump together in the body and form deposits, along with protein and cholesterol. They then lodge in the cells, organs and blood vessels. This can lead to many health problems, including obesity, heart disease, and breast and colon cancers.
UNSATURATED FATS: Unsaturated fats are called such because there are at least two adjacent carbon atoms on a chain which are not attached to hydrogen atoms. When at least two pairs of carbon atoms are empty it is known as a monounsaturated fatty acid. When two or more sets are empty, then it is referred to as a polyunsaturated fatty acid. A good rule of thumb is that the more saturated the fat, the more easily it will stay hard at room temperature.
ESSENTIAL FATTY ACIDS: Essential fatty acids (EFAs) are vital nutritional components that our bodies need for many functions. They are found in the seeds of plants and in the oils of cold-water fish. Essential fatty acids—sometimes referred to as vitamin F— cannot be made by the body; they must be sup-plied in the diet. However, at this time, the government has not officially established a Recommended Daily Intake (RDI). Many factors, including stress, allergies, disease, and a diet high in fried foods, can increase the body’s nutritional need for essential fatty acids.
MECHANISMS OF CHITOSAN FAT- BINDING
June 25, 2005 08:02 PM
MECHANISMS OF CHITOSAN FAT- BINDING
The exact way(s) that Chitosan prevents fat absorbtion is not fully understood but a number of experimental observations support two basic mechanisms. The first mechanism involves the attraction of opposite charges which can be compared to the attraction of opposite magnetic poles. The second entrapment mechanism can be compared to the effect of a net. In the first mechanism the positive charges on chitosan attract the negatively charged fatty acids and bile acids binding them to the indigestible chitosan fiber. This mechanism can explain why chitosan reduces LDL cholesterol levels.
Our bodies make bile acids in the liver using the cholesterol from LDL. When chitosan binds bile acids it increases the rate of LDL loss thus improving the LDL to HDL ratio. If enough bile acids are bound, the fats are not solublized, which prevents their digestion and absorption. The second mechanism (figure 2) describes a netting effect of chitosan fiber.
In this model the Chitosan wraps around fat droplets and prevents their being attacked and digested by lipid enzymes. Fats unprotected by Chitosan are digested and absorbed. The “netting” mechanism has been seen to operate in vivo. 108
Substances that Enhance the Action of Chitosan
Fibers can be likened to a tangled-up chain. Fibers must “unravel” in order for them to be of maximum benefit to us. “Unraveling” is especially critical for chitosan because each link has a hook on which to attach lipids. Chitosan can absorb an average of 4 to 5 times its weight in lipids. Reports of numbers above and below this range have also been reported and may well reflect the rate or extent of unraveling that had taken place. Fiber formulations can be prepared that unravel rapidly and swell quickly. These highly effective formulations are called superabsorbants. When certain substances are added to chitosan, its remarkable fat-binding ability can be significantly enhanced.
D-Ascorbic acid (erythorbic acid) and L-ascorbic acid are C-vitamins which enhance chitosan’s ability to bind lipids. Combining chitosan with ascorbic acid results in even less fat absorption and greater fecal fat losses.77,108 In one study the addition of ascorbic acid to a chitosan enriched diet increased fecal fat losses by 87 percent and decreased fat absorption by over 50 percent.77
Cholesterol oxides cause lesions in artery walls which predispose blood vessels to collect plaque. These dietary cholesterol oxides profoundly influence the initiation of heart disease.Free radicals can also contribute to the formation of cholesterol oxides which are even more likely to damage the heart. Cholesterol oxides have been found in deep-fried foods, powdered eggs, processed meats and in human blood itself. Consequently, taking antioxidants like ascorbic acid is vital to protect against the cellular damage this type of free radical causes.112
In feeding experiments with animals, adding citric acid to a chitosan enriched diet resulted in a decreased feed consumption.77 The most likely explanation for this effect is that the citric acid may be enhancing the swelling action of chitosan leading to a sense of fullness, producing satiety and appetite suppression.
Indoles are remarkable phytochemicals which have the ability to selectively activate certain Mixed Function Oxidases (MFOs).113 These MFO’s help balance estrogen metabolism and prepare dietary toxins for elimination before they are absorbed. The presence of fiber in the intestines provides a bulk agent to carry the metabolized toxins out of the body. Chelat ed Minerals The very best approach to weight loss is to nutritionally augment food choices with nutrient supplementation. Certain biochemical compounds are essential to promoting vigor during the process of thermogenesis. Chelated minerals act to bolster, support and protect the organ systems of the body.114,115
For example, when fat is burned, heat and energy are released. If a lack of certain minerals exists, energy levels will drop. Minerals help to transport needed nutrients to depleted areas of the body, thereby stemming off the fatigue we so often experience after eating a fatty meal. Even more importantly, free radicals are released whenever fat is consumed and burned and the presence of chelated minerals helps to expedite the removal of these metabolites and facilitate the availability of fuel for energy.
Essential Fatty Acids
Prostaglandins control and balance many body functions. The dietary building blocks for making prostaglandins are the essential fatty acids (EFAs). The role of prostaglandins in weight loss has been extensively discussed in a recent review.116 EFAs exert profound lipid-lowering effects.They reduce the synthesis of triglycerides and very low density lipoproteins (bad cholesterol) in the liver. EFA supplementation coupled with a low-cholesterol, low-saturated fat in diet produces a complementary effect in lowering serum lipid levels.117 Garcinia Cambogia ( Hydroxy Cit ric Acid) Garcinia Cambogia contains hydroxycitric acid (HCA). This form of citric acid inhibits the liver’s ability to make fats out of carbohydrates.118
Carbohydrates are converted to glycogen stores, not fat stores, giving the body a better energy reserve and an increase in stamina.119 Ephedra And Thermogenisis Thermogenesis means “creating heat.” This is one of the ways our bodies have of burning off excess calories and maintaining a constant weight.120 This is an area of weight management research that is being intensely studied. When we repeatedly yo-yo diet or abuse ourselves by eating too much, our thermogenic ability may be reduced. Numerous animal and human studies have confirmed the benefits of ephedra and methylxanthines in inducing weight loss and restoring thermogenic responsiveness.43,44,121
