Space travel could become a real viable option for most people in the very near future. But, you may ask, what kind of health problems can arise from traveling in outer space? Well, nutrition for one, could be an area of concern in space travel, since most food would consist of re-hydrated food pouches. Fresh foods during space travel are rare, so vitamins are a must to ensure proper health is maintained. Another health concern for a space traveler may be hygiene. While on board a space flight, water is limited. Showering and changing clothes daily may not be an option. Water is precious and even urine is recycled and reused. In addition, a person's mental health will certainly be tested from being in such a small confined area during the journey. Sleeping, as well, takes a little more thought, since falling asleep without being tethered could cause one to be injured or even float away! Lastly, the main health concern would probably be radiation exposure which could lead to cancer or "space brain," a condition that causes brain damage. These areas of health concern would need to be considered before deciding if boarding the next spacecraft is the right choice for your one of a kind vacation in the near future. Happy travels!!

Melatonin historyThe pattern according to which a human being wakes up and remains awake during the day and falls asleep at night is regulated by a hormone known as Melatonin. This hormone was first discovered by a team of researchers that was led by a Yale dermatologist by the name of Dr. Aaron Lerner. While Lerner passed away on the 3rd of February, 2007, however, his discovery was quite groundbreaking in medical science. Initially back in 1958, the Melatonin hormone that was isolated from the pineal gland inside a frog's brain was believed to be a cure for skin pigmentation problems. However, it was later discovered that rather than helping to treat skin pigmentation problems, this hormone had a role in regulating the wake and sleep pattern of human beings. There, Dr. Aaron Lerner and his team of researchers came to conclusion that sleep related problems; especially insomnia could be treated using this hormone. Sleep disorders Almost millions of Americans these days are suffering from sleep disorders include insomnia, narcolepsy, etc. Insomnia, in particular, is not really a disease but is merely a disorder or a symptom that makes an individual sleepless and makes it difficult for them to fall asleep. In fact, people suffering from insomnia are hardly able to get any quality sleep, especially at night, which is most essential for them. Those people who have had a couple of sleepless nights can be certain that they are suffering from insomnia, however, people rarely visit a doctor when suffering from this sleep disorder. There are a variety of reasons that cause insomnia. Anxiety, depression, discomfort, specific medical illnesses, stress, etc. are some of the most common causes of insomnia. Insomnia can last for both short and long periods of time. When it comes to safely treating insomnia, the melatonin hormone can be used for this purpose. Presently there are numerous natural melatonin supplements available in the market that can be used by insomniacs as a remedy for the sleep disorder they are suffering from. It was somewhere during the mid 1990s when this hormone became available in the form of pills. At that time tRAVELERs who frequently suffered from jet lag used supplements containing this hormone. Melatonin benefits These days, after further research claims are being made that many other benefits are also offered by this antioxidant hormone. Research has proven that headaches and migraines, which are among the causes of insomnia, can be effectively relieved by using supplements containing melatonin. It is believed that the certain cancers can also be prevented from further developing with the help of this hormone. As for insomnia, it is a sleep disorder that disrupts the natural sleep and wake pattern of the body. This hormone, therefore, restores that pattern back to normal causing people to feel sleepy at the right time when they actually need sleep. This sleep is being promoted by a natural hormone so these supplements cannot be considered drugs and neither do they cause an individual to feel as if they are drugged. Insomniacs will simply begin feeling naturally sleepy and this is why it is safe to use melatonin supplements to treat insomnia. Give it a try and feel the difference

The mugwort plant is one of several species in the genus Artemisia. In Northern America, this plant is considered to be an invasive weed. The plant is very common and can be found growing on nitrogenous soils, like weedy uncultivated areas such as waste places and roadsides. The mugwort plant is a tall herbaceous perennial plant that grows from one to two meters tall and has a woody root. The leaves, which are between five to twenty centimeters in length, are dark green, pinnate, with dense hairs on the underside. The stem has a red-purplish tinge. The flowers are rather small with many yellow or dark red petals. This plant can be found flowering from July to September. The mugwort plant is native to Europe, Asia, and northern Africa. Sometimes, it is referred to as the felon herb, St John’s plant, chrysanthemum weed, and wild wormwood. The plant’s root has a history of medicinal use. Mugwort was used in the ancient world as a treatment for fatigue and to guard tRAVELERs from evil sprits and wild animals. Roman soldiers are said to have placed mugwort in their sandals to keep their feet energized. One could curb fatigue by chewing mugwort leaves. Sometimes, mugwort is confused with wormwood. Mugwort is popular in witchcraft. It is said to promote lucid dreaming and astral travel. Smoking or eating mugwort before going to sleep is supposed to make dreams much more intense. It also helps the dreamer to remember them upon waking. This herb contains wormwood oil, thujone, flavonoids, triterpenes, and coumarin derivatives. Thujone is toxic. For this reasons, expectant mothers should avoid consuming large amounts of mugwort. Due to toxicity concerns, the plant is recommended less often now. In traditional Chinese medicine, mugwort still has a role in an aged, pulverized, and recompounded form. In this form, it is used to correct breech birth presentation. Additionally, mugwort can cause uterine contractions, so it has been used to induce abortion. The leaves of the mugwort plant have been recommended for colic, diarrhea, constipation, stomach cramps, weak digestion, worm infestation, and persistent vomiting. This herb has also been used to stimulate the secretion of bile and gastric juices. It has also been used as a laxative, liver tonic, and sedative. Mugwort promotes circulation. Additionally, it helps with hysteria, epilepsy, convulsions in children, and menstrual problems. This herb has been used as a tonic to boost energy and strength. It has been used, combined with other ingredients, for neuroses, neurasthenia, depression, hypochondria, irritability, restlessness, insomnia, and anxiety. In summary, the root and leaves of the mugwort plant are used to provide abortifacient and anthelminthic properties. The primary nutrients found in this herb are lipophilic flavonoids and sesquiterpene lactones. Primarily, mugwort is extremely beneficial in treating anxiety, colic, constipation, depression, diarrhea, digestion, epilepsy, hysteria, insomnia, menstrual problems, vomiting, and worms. In order to obtain the best results when supplementing with this, or any herb, it is important to consult your health care provider before beginning any regimen. For more information on the many beneficial effects provided by mugwort, please feel free to consult a representative from your local health food store with questions.

Date:
August 23, 2008 11:59 AM
Acidophilus is correctly named Lactobacillus acidophilus, and is one species of Lacobacillus used commercially in the preparation of certain types of yoghurt. The name refers to the fact it is found in milk (lacto), is rod-like in shape like many bacteria (bacillus) and it likes acidic conditions (acidophilus). It not only likes them, but creates them. In fact, acidophilus thrives at a pH of 4-5 or less, and occurs naturally in the gastrointestinal tract of humans and animals, and also the mouth and vagina. It ferments milk to lactic acid, and dies in the presence of sunlight, excessive moisture and at high temperatures. Some, but not all, strains are probiotic, or ‘friendly’ bacteria that aid digestion and help to protect against harmful bacteria and their toxic emissions. The fermentation of nutrients by friendly bacteria produce acids, such as the lactic acid previously referred to, hydrogen peroxide and other substances hostile to harmful organisms, and also reduces the population of harmful bacteria by competing for their food. There are additional health benefits that shall be discussed later, but first some comments about the stability of acidophilus to heat. The growth rate of acidophilus reaches an optimum at around 36-37F (2.2C), and it tends to die off at temperatures much above this over a period of time. It also tends to be sensitive to oxygen and moisture, and if exposed to heat, moisture and oxygen, a supplement will lose its potency over time. This is true of all such supplements, and after purchase must be quickly refrigerated. It is possible, however, to purchase stabilized forms of acidophilus that die off slower than normal. This extra resistance is built in during the manufacturing process, and many forms of acidophilus claim to be stable. Although there will never be a truly stable form of the probiotic, these stabilized versions do last longer than those not claimed to be so. During manufacture, the bacteria are first concentrated by removing the excess liquid by means of sedimentation, ultra-filtration, reverse osmosis and centrifuging. A substance is then added to protect the bacteria from the shock of freezing and the acidophilus freeze dried. A stabilizer is then added to maintain its properties between freezing and consumption. It has also been found that bacteria grown at higher pH levels last longer than those at lower pH. The packaging is also important, and since the bacteria are sensitive to oxygen, nitrogen flushing the bottles will improve the stability of the product. Glass bottles are less porous than plastic, and so is the preferred packaging material for maximum stability and life. Another factor is refrigeration. If you keep the bottle in the fridge it was last a lot longer than at room temperature, but take care not to freeze it since acidophilus does not freeze well. If it is not refrigerated then it will quickly lose its potency. The form in which you take the supplement is immaterial regarding the potency: at least initially. However, through time the powder will become less potent quicker, because it will adsorb oxygen and moisture. Otherwise the form in which it used is immaterial. So, yes, acidophilus can be stabilized, but only for a while, and if allowed to warm up to room temperature in the presence of oxygen will quickly degrade, although this takes more than just a day or two. Many health benefits are claimed for Lactobacillus acidophilus, although your daily consumption to achieve these should be at least 2 billion CFU, and preferably 5 billion. You can also fortify the bacteria with a prebiotic of fructooligosaccharides (FOS). These provide nutrition for the acidophilus and accelerate its growth. One thing to be careful of is assuming that yoghurt contains acidophilus. It does not contain sufficient to be of benefit to you. Commercial yoghurt acidifies over time and kills off the bacteria, so commercial yoghurt sitting on a supermarket shelf has very little beneficial bacterial content. Natural yoghurt is better, and certainly contains beneficial bacteria, but not enough to make a significant difference. A supplement is therefore needed if you are to keep your intestinal tract sufficiently healthy. If you cannot take dairy products, acidophilus is available in non-dairy form. The major health benefits they impart are: 1. Digestive Problems. Acidophilus can control many types of digestive disorder, particularly tRAVELER’s diarrhea. In fact if you are traveling to countries where drinking water might be a problem, also take some acidophilus and this will tend to prevent you from becoming ill. Even if you drink bottled water, there are still washed salads, beverages made with local water and showers and the like whereby you could ingest some dodgy water. 2. Constipation Acidophilus, especially when supported by FOS, helps both to hydrate the feces, and improve their transport through the colon, an also to improve the general health and well-being of your entire intestinal system. 3. Yeast Infections (Candidiasis) Acidophilus possess antifungal properties that kill off yeasts, particularly Candida albicans found in the vagina. This is due to the lactic acid produced by the bacteria, and there is evidence that gastrointestinal yeasts are affected in the same way by the oral probiotic. Furthermore, when bacteria and yeasts are killed off by medication, including friendly bacteria, the sites they occupied on the intestinal walls become free and acidophilus should be present to take these up and prevent any more yeast or bacterial infections. That is one reason why probiotics should be taken immediately after a course of antibiotic treatment. 4. Immune System Support Lactobacillus acidophilus is believed to modify the balance of microbes in the intestine so as to lead to an enhanced production of antibodies, and white blood cells with increased phagocytic activity. The bacteria also appear to have some reducing properties, which can also give support to the immune system through the resultant antioxidant properties. However, by far the most important property of probiotics are their properties in acidifying the intestinal tract, and so rendering them less attractive to harmful pathogens, and in producing hydrogen peroxide which has a similar effect. They also produce natural antibiotics, and there is now doubt that a supplement of acidophilus will provide you with several health benefits and also make you feel fitter and more alert.

Date:
November 03, 2006 12:16 PM
Pycnogenol (pronounced pic-nojen-all) is a natural plant extract originating from the bark of the maritime pine that grows along the coast of southwest France. Pycnogenol® consists of particularly bioactive flavonoid species and its purity is in strict accordance with the United States Pharmacopoeia. Pycnogenol® was initially developed 35 years ago in Europe. During the past years it evolved as one of the most thoroughly researched nutritional supplements, with over 200 studies published in peer-reviewed journals. Seventy of these studies were clinical with in total more than 4,000 patients. Pycnogenol® taken in dosages from 25mg to 300mg is well tolerated and Pycnogenol® was attributed “generally recognized as safe” (GRAS) by the FDA. Pycnogenol® supports healthy capillaries The “Career” of Pycnogenol® began in Europe, where it was first used to maintain vein and capillary health. Pycnogenol® has been shown to strengthen blood vessel walls, with 15 clinical trials showing fast relief from ankle and foot discomfort. A recent study with 200 passengers on long-haul flights showed that Pycnogenol® taken before departure and again during the flight supports foot comfort and healthy circulation. TRAVELERs typically comment that with Pycnogenol® it is much easier to put shoes on again upon arrival. Clinicians in Germany discovered that Pycnogenol® also supports healthy capillaries in the eyes. Retinal capillaries may be affected by imbalanced blood sugar levels. In a multi-center field study with 1169 subjects Pycnogenol® supported healthy capillaries in the retina and improved visual acuity to some extent. Pycnogenol® benefits the cardiovascular system More detailed investigation of the interaction of Pycnogenol® with blood vessel walls at the University of Florida, Tampa led to an amazing discovery. Pycnogenol® stimulates an enzyme in blood vessel walls that is responsible for generating the most important vascular mediator, known as “nitric oxide” (NO). NO triggers relaxation of the arteries and supports clear blood flow. Hence, NO is the body’s mediator for maintaining healthy blood pressure levels and circulation. NO plays such an important function for cardiovascular health that Dr. Louis Ignarro (UCLA) and his co-workers received the Nobel Prize for this discovery in 1987. A number of factors, including aging, can interfere with the body’s efficient production of NO. Supplementation with Pycnogenol® for four weeks was shown to restore NO production and improve blood supply to the fingertips of elderly people in a Japanese study. Microscopic evaluation of blood vessel diameter at the root of fingernails showed an increased diameter of capillaries allowing better blood perfusion. Specific sensors applied to the legs showed increased oxygen and decreased carbon dioxide presence. Better blood, nutrient and oxygen supply with Pycnogenol® benefits everybody. Italian researchers were able to show that regular intake of Pycnogenol® helps defy muscle cramps and minor pain in athletes. The relaxation of arteries has a favorable effect on blood pressure. In two clinical studies Pycnogenol® taken for at least eight weeks was found to significantly support normal blood pressure. Pycnogenol® stimulated NO generation directly translates into clear blood flow. This was first demonstrated at the University of Arizona, Tucson in smokers. Pycnogenol® dose-dependently, starting at a single dose of 25mg, countered the typical effects of cigarette smoking on the blood. Also, Italian vascular specialists found that Pycnogenol® supported the circulation of individuals on flights between New York and London. Pycnogenol® supports healthy blood sugar levels Pycnogenol® can support normal glucose levels when taken as part of a healthy diet and lifestyle plan. A clinical investigation has confirmed the significant glucose-lowering effect of Pycnogenol®. It was noted that Pycnogenol® did not affect insulin levels. Pycnogenol® appears to facilitate previously insulin-resistant cells to uptake sugar from the blood stream by yet unknown mechanisms. Pycnogenol® limits cellular irritation Two clinical studies carried out in Germany this year with student volunteers demonstrated that Pycnogenol® has a potent effect in preventing cellular irritation. Pycnogenol® inhibits a molecular “main-switch” in immune cells that triggers the onset of cellular irritation in any part of the body. Moreover, Pycnogenol® was found to inhibit so-called COX enzymes, which are involved with minor pain-sensation related to cellular irritation. Pycnogenol® sooths menstrual pain Japanese gynecologists discovered in 1999 that regular supplementation with Pycnogenol® soothes the normal discomfort of menstrual pain, particularly during cramping. Another clinical investigation of 47 women in year 2004 confirmed the effect of Pycnogenol® in addressing menstrual pain. This year a double-blind, placebo-controlled, multi-center field study with 116 women again confirmed these results. Pycnogenol® is not suitable for on-demand relief during menstruation. The studies show that Pycnogenol® reached highest efficacy when taken regularly for months. Pycnogenol® helps to support respiratory health Challenges to normal respiratory function may result from incidents the immune system perceives as harmful. Pycnogenol® offers valuable help in supporting respiration due to its immune-modulating effect and its ability to limit cellular irritation. A study at the University of Arizona found that Pycnogenol® supports clear breathing and lowers mediators of cellular irritation in the blood stream. More recently, a placebo-controlled clinical study at the University of California, Loma Linda described how Pycnogenol® supported healthy respiration in 60 children aged 6-18 years. Pycnogenol® needs to be taken continuously for prolonged periods of time for maximum benefit to the respiratory system. Pycnogenol® is investigated in clinical trials all over the world. New findings are posted on the website www.pycnogenol.com. Frank Schonlau Ph.D. is a biochemist who has spent nine years in medical research at the University Clinic of Munster Germany. His area of expertise covers vascular disorders, inflammation and dermatology. He has published more than 20 studies and review articles in the medical literature. Since entering the dietary field in 1999 he was involved in numerous studies on Pycnogenol® and communication of new health discoveries.

Date:
December 21, 2005 11:04 AM
“To the dull mind, nature is leaden. To the illumined mind, the whole world burns and sparkles with light.” Ralph Waldo Emerson From the moment we rise to the moment we rest, our brain is in a decision-making frenzy. When we’re thirsty, our brain tells us that we need water. When we’re hungry, it reminds us that we have a refrigerator full of food. When we’re tired, it lets us know that we need to sleep, and so on. But despite the thousands of decisions we make everyday, our brain still hasn’t figured out a way to let us know what it needs to func¬tion. Though ironic, this raises a very serious issue. The human brain, like every other organ in the body, demands nutrition - period. Unfortunately, it leaves that up to us to figure out. Thanks to notable advance¬ments in research, we’re finally learning which nutri¬ents are most important for optimal brain function. Phosphatidyl Serine (PS) is a perfect example. This naturally occurring phospholipid has been the subject of numerous studies regarding its ability to boost cognitive function and delay (or potentially reverse) memory deterioration, and suggests that PS may be able to increase the effectiveness of neural transmissions. Interestingly, PS accounts for roughly 15% of the brain’s phospholipid supply. This is enor¬mous because phospholipids play a significant role in the billions of neurotransmissions that take place every second. Yes, billions. Brain cells are constantly communicating with one another, and send astonishing amounts of impulses throughout the nervous system. This is accomplished via neurotransmitters - chemical messengers that send and receive impulses over the synapses of the brain and throughout the body. Mentally, we’re function¬ing at our best when these cells are well nourished. We can think more clearly, recall memories with ease and operate with greater efficiency. However, a de¬ficiency in neural-nutrients can prevent these mind messengers from functioning as they should. For¬tunately, PS has the ability to cross the blood-brain barrier to deliver critical nutrients and remove mind-slowing waste. Consider this. The brain functions in the same man¬ner that a major airport does around the holidays. There are millions of actions taking place. Impulses departing, nutrients arriving, endless communication, the occasional problem and more reactions than any¬one could possibly count. There’s confusion, delay and emotion, not to mention the endless series of transmissions that take place every second. Imagine PS as that ultra-motivated employee who shows up to work everyday anxious to expedite everything in sight. It helps neural tRAVELERs get to and from their respec¬tive gates, ensures that they have everything they need, simplifies processes that could result in breakdown, and clears isles that are cluttered with junk. Simply stated, PS is the brain’s overachieving go-getter. PS can help us think more clearly. It’s 3:06 in the afternoon and you’re scrambling to get to a meeting that you’re already late for. That fluster could be the result of poor neurotransmission caused by a deficiency in essential nutrients like PS. Moreover, these innocent brain-bursts can exhaust our PS reserves, leaving us somewhere hovering be¬tween frantic and sluggish. Every impulse, thought, action, reaction, movement, emotion and desire is the end result of neurotransmitters in action. PS is a major supporter of these actions. Therefore, as we increase the amount of PS in our system, we gain the ability to think and act with greater ease. PS can reduce the adverse impacts of stress on our body and mind. What do we do when we’re down in the dumps? While plopping down on the sofa with a snack might be an easy solution, it comes with a price. Not only does stress interfere with mood, but it can also inspire inactivity, over-eating and sluggishness. This is due largely in part to cortisol - a catabolic hormone released by the adrenal glands in response to emotional stress. Studies done to determine the effectiveness of PS on cortisol suppression have shown that it works by suppressing the hormones that produce cortisol. As a result, supplementing with PS may be able to help reduce the amount of stress related hormones that ultimately leave us singing the blues. PS can expedite post workout recovery time. Endurance athletes who carefully monitor their body’s response levels are increasingly turning to PS. Immediately following strenuous activity, the body responds by releasing adrenocorticotropin (ACTH) – a hormone that discourages testosterone and encourages cortisol. By limiting ACTH pro¬duction, PS reduces the amount of muscle tissue breakdown that occurs during exercise. A common misconception is that muscles grow during exercise - wrong. In fact, muscles are torn down during ex¬ercise and grow in-between workouts – hence the term recovery. During recovery, PS helps prevent the activity of growth-inhibiting hormones. This helps athletes recover faster so their gains are realized more quickly. In short, Phosphatidyl Serine appears to be a completely safe and beneficial dietary supple¬ment that can offer a wide range of physical and mental health benefits. NOW® Phosphatidyl Serine is derived from soy leci¬thin, and includes Choline and Inositol – two metabolites that work synergistically to help in¬crease circulation and cognitive response.

Date:
June 18, 2005 09:07 AM
Anti-Aging Nutrients by Edward C. Wallace, DC, ND Energy Times, February 3, 2000 What's the big deal about trying to live longer? As you grow older (and the American population grows older alongside you) you may want to postpone the inevitable. Few wish to hasten "the journey from which no tRAVELER returns." But as we approach that final bon voyage, chances are we desire clear sailing-aging without disability and with a peaceful, easy feeling. How Do We Age? Science has long puzzled about what causes the wrinkles, pains and deterioration of aging. In the search for causes, two basic theories have won over the most proponents: The first holds that cells are programmed with biological clocks that predetermine how many times they can reproduce before becoming non-functional. This theory has been largely formulated by the researcher Leonard Hayflick, MD. The second basic theory, introduced by Denham Harman, MD, PhD, in the mid 1950s, holds that cells eventually break down due to attack by caustic molecules called free radicals that cause oxidative stress. Programmed Cell Theory In the early '60s, Dr. Hayflick observed that human fibroblasts (cells from connective tissue) in the laboratory refused to divide more than about 50 times. Dr. Hayflick also found that even if he froze the fibroblasts after 20 divisions, they would remember that they only had 30 divisions left after thawing. Fifty cell divisions have been called the "Hayflick limit." Based on this research, scientists theorize that cells maintain a genetic clock that winds down as old age ensues. Many researchers believe the hypothalamus gland is the force behind our aging clocks, signaling the pituitary gland to release hormones that cause aging. Free Radical/Oxidative Stress Theory The other popular theory of aging pictures the human body as a cellular battlefield where attackers called free radicals damage our cells and tissues, making them age. In this scenario, a process called oxidation is the chief aging villain. On a microscopic level, oxidation generally entails molecules or atoms losing electrons. (Gaining electrons is called reduction.) The molecules or atoms that take these electrons are oxidizing agents. Free radicals are substances that can exist with missing electrons, making them readily able to donate or accept electrons and damage structures in cells. As such, they are highly reactive, binding with and destroying important cellular compounds. Most of the free radicals in your body are made during metabolic processes. More are added from the food you eat and environmental pollution. Most of these free radicals contain oxygen molecules. As each cell makes energy in little structures called mitochondria, free radicals result. These oxidant by-products can damage DNA, proteins and lipids (fats). Consequently, toxic by-products of lipid peroxidation may cause cancer, inhibit enzyme activity and produce mutations in genetic material that make you age faster. DNA Repair Theory Free radical damage to DNA can cause cells to mutate or die. Your body makes enzymes that can repair this damage and slow aging. But, over time, the amount of damage overwhelms the body's ability to fix things. As cells grow older, their ability to patch up DNA diminishes and the rate of damage proceeds faster than repair. The result: We age and eventually die. What Can We Do? The free radical theory of aging suggests that taking antioxidants (compounds known to prevent free radical damage) in our food or as supplements may slow aging. In the publication Age (18 [51] 1995: 62), it was reported that "aging appears to be caused by free radicals initiated by the mitochondria at an increasing rate with age. Superoxide and hydrogen peroxide radicals formed by the mitochondria during normal metabolism are major risk factors for disease and death after about the age of 28 in developed countries. Antioxidants from the diet lower the production of free radicals without impairing essential reactions to maintain body function." Antioxidant Protection Common dietary antioxidants include: vitamins E and C, carotenes, sulphur containing amino acids, co-enzyme Q10 and flavonoids (a group of plant compounds or pigments responsible for the color in fruits and flowers). In addition, melatonin, DHEA and the amino acid compound glutathione may also prove of benefit. Glutathione along with the enzyme glutathione peroxidase are an essential part of free radical "quenching." (Quenching means changing free radicals into benign substances no longer capable of harm.) Deficiencies may suggest a decreased capacity to maintain detoxification and metabolic reactions in which glutathione plays a role, resulting in increased free radical stress and/or lipid peroxidation. Drinking too many alcoholic beverages can result in glutathione deficiency. In a study in which 39 healthy men and 130 healthy women between the ages of 20 and 94 were evaluated for glutathione levels, the older subjects had significantly decreased levels (especially in the 60 to 79-year-old group). The authors felt that physical health and longevity were closely related to glutathione levels (Jrnl Lab & Clin Sci 120(5), Nov. 1992: 720-725). Poor nutrition and/or deficiencies in essential micronutrients and many prescription medications may contribute significantly to detoxification capacity in an aged individual. All of these circumstances are common in the elderly. Eating a poor diet that contains too many processed foods without many fruits and vegetables can compromise your body's ability to detoxify pollutants, toxins and other harmful compounds. That can set off metabolic processes capable of fomenting large increases in free radical stress that can accelerate aging. Unfortunately, even in a country as prosperous as our own, nutrient deficiencies are frequent, especially in older citizens. Nutrition Deficiencies A study that looked at what elderly people consumed compared their reported intake with the 1989 Recommended Dietary Amount (RDA) and 1980 RDA: One of four people consumed only two-thirds of the RDA for calories and 60% consumed less than two-thirds of the RDA for vitamin D. As for other nutrients, 50% were found to have inadequate zinc levels (less than two-thirds of the RDA), 31% lacked calcium, 27% were short of vitamin B6, 25% didn't get enough magnesium, 7% missed out on folate and 6% ate less than two-thirds of the requirement for vitamin C (Nutrition Reviews (II), September 1995: S9-S15). When researchers examine what everyone in the U.S. eats, they find that only 9% of Americans consume the recommended five servings of fruits and/or vegetables per day (Proceedings of the National Academy of Sciences, Sept 1993). A diet high in fruits and vegetables is naturally high in antioxidant compounds and is believed to help you live longer. Unfortunately, if you buy your produce in the supermarket, those fruits and vegetables may also be rich in pesticide and herbicide residues (Consumer Reports, March 1999). Obviously, organic produce lacks these residues. But, in any case, research continues to indicate that a diet low in meats and animal fat and high in vegetables protects against antioxidant damage. Longevity Diets A six-year study of 182 people over age 70 in rural Greek villages found that those following their traditional diet of olive oil, whole grain breads, fresh fruits and vegetables and wine were less likely to die during the study than those who consumed more red meat and saturated fat. The most important foods in lowering the risk of early death included fruits, vegetables, legumes (peas and beans), nuts, dairy products and cereals (BMJ 311, 1995: 1457-1460). Another article in Epidemiology highlights the evidence that eating a vegetarian diet increases your chances of living longer. Included in this survey is a recent country-wide study of diet and health in China, showing that the traditional near vegetarian diet of 10% to 15% of calories coming from dietary fat reduced the chances of heart disease, diabetes and many types of cancers (Epidemiology 3[5], 1992: 389-391). Staying Alive Staying skinny and limiting what you eat may also increase longevity. Scientific studies have previously shown that being overweight can theoretically curtail your life, increasing the risk of heart disease, diabetes and other life-shortening conditions. Animal studies have also shown that restricting food can slow diseases associated with aging. Researchers believe that cutting calories helps your immune system stay younger by reducing the formation of substances that are called proinflammatory cytokines. Specifically reducing your intake of fatty foods may decrease your chance of coming down with autoimmune diseases. Researchers think omega-6 fatty acid vegetable oils (like corn oil) may increase free radical formation and decrease levels of antioxidant enzyme messenger RNA in addition to other effects (Nutrition Reviews 53[4], 1995: S72-S79). Another study found that cutting calories lowers the levels of oxidative stress and damage, retards age-associated changes and extends maximum life span in mammals (Science 273, July 5, 1996: 59-63). In yet another study, it was shown that caloric restriction early in the life of lab animals increased their life span by a whopping 40% (Australian Family Physician 23[7], July 1994: 1297-1305). Today's modern higher-fat, low-fiber diet with substantial sugar consumption represents everything the longevity researchers say you shouldn't eat. Longevity and Exercise Exercise may slow aging. When researchers looked at the exercise habits of 17,000 men, average age of 46, they found that those who took part in vigorous activity lived longer. Exercise can improve both cardiac and metabolic functions within the body, while also decreasing heart disease risk. Even modest exercise has been shown to improve cholesterol and blood sugar levels (JAMA 273[15], April 19, 1995: 1179-1184). In a study of how exercise affects your chances of living longer, 9,773 men underwent preventive medicine examinations on two different occasions. When the researchers looked at who lived longest, they found the highest death rate was in men who were unfit during both physical exams. The Treadmill of Life The lowest death rate was in the men who worked out and were in good shape. The researchers concluded that for each minute increase in how long a man could keep treading on a treadmill (between the first and second exam) there was a corresponding 7.9% decrease in the risk of dying (JAMA 273 [14], April 12, 1995: 1093-1098). Since exercise can increase oxygen consumption up to 10 times, boosting the rate of production of free radicals, researchers believe that older individuals need more antioxidant nutrients to protect them. In a paper published in Aging Clinical and Experimental Research (1997), researchers stated that if you regularly exercise in your golden years, you should take more antioxidant vitamins to compensate for this risk. Longevity Supplementation Melatonin is not often thought of as an antioxidant, but, instead, as a sleep aid. Melatonin, however, is an effective and efficient free radical scavenger and may help stave off the effects of aging. Melatonin protects against what are called hydroxyl free radicals. Research shows that older people's lack of melatonin may make them more susceptible to oxidative stress. In one study, researchers felt that new therapies aimed at stimulating melatonin synthesis may eventually lead to therapies for the prevention of diseases related to premature aging (Aging and Clinical Experimental Research 7[5], 1995: 338-339). Melatonin was shown to provide antioxidant protection in several ways. Toning Down Enzymes Melatonin can ease the effects of enzymes that generate free radicals, enhance the production of glutathione peroxidase (an antioxidant) and defuse the caustic action of free radicals that contain hydroxyls. In several studies, DHEA supplementation has been shown to potentially revive immune function in older adults (Exp. Opin. Invest. Drugs 4[2], 1995: 147-154). In a study of 138 persons older than 85 years compared to 64 persons 20 to 40 years of age, scientists found that the younger people had four times as much DHEA in their bodies. The researchers believe that our bodies make less and less DHEA as we get older. The authors of this study raise the possibility that declining DHEA may be partly to blame for our biological clocks running down (New York Academy of Sciences 1994: 543-552). Vitamins E & C A growing body of research also supports the benefits of taking vitamins E and C to hold off the effects of getting old. Researchers writing in Free Radicals and Aging (1992: 411-418) point out that as you get older your body is home to more and more free radical reactions that may lead to degenerative diseases like heart disease and arthritis. Research has found that in older people with exercise-induced oxidative stress, taking vitamin E every day may significantly fight off free radicals. (To investigate this effect, scientists measured waste products in urine that result from free radical reactions.) Their conclusion: Dietary antioxidants such as vitamin E may be beneficial. Chronological Age Vs.Biological Age Vitamin C also looks to scientists like a good anti-aging bet. Research in the Journal of Advancement in Medicine, (7[1], Spring 1994: 31-41) showed that folks consuming larger amounts of vitamin C were less likely to experience clinical problems at all ages. Those taking in less than 100 mg of vitamin C per day also suffered the most problems. In this research, individuals over 50 years of age who daily consumed the largest amount of vitamin C were as healthy or healthier than the 40 year olds who were taking the least amount of vitamin C. Similar Relationship A similar relationship appears to exist for vitamin E and serum cholesterol levels. In a study of 360 physicians and their spouses, researchers found that people in their 50s who consumed more vitamin E had lower cholesterol than those in their 30s who were taking less. And the longevity beat goes on: In a study evaluating environmental tobacco smoke and oxidative stress, researchers divided 103 people into three groups. Researchers blew smoke at 37 of these folks without protection while 30 of them got to breathe tobacco smoke but took antioxidant supplementation. Another 36 of them merely had to read magazines from doctors' offices. The results: After 60 days of supplementation the antioxidant folks had a 62% reduction in evidence of oxidative damage to their DNA. Cholesterol levels dropped and so did antioxidant enzyme activities. The researchers concluded that taking antioxidants provided a modicum of protection against environmental poisons. The range of antioxidant nutrients used in this study included: beta-carotene, vitamin C, vitamin E, zinc and selenium as well as copper (Cancer Epidemiol Biomarkers Prev 7, November 1998: 981-988). Carotenoids When you mention carotene or carotenoids, most people think of the beta carotene that makes carrots orange. But more than 600 carotenoids are present in colorful vegetables and many of these misunderstood substances are more potent antioxidants than beta-carotene. Carotenoids have been shown to destroy oxygen free radicals in lipids (fats), help protect our cells from the sun's ultra violet radiation and enhance our natural immune response (J. Nutr 119[1], Jan. 1989: 112-115). Some evidence seems to show that how much carotenoids you (and other mammals) have in your cells may be the predominant factor in determining life span (Proc Natl Acad Sci 82 [4], 1985: 798-802). Therefore, a diet rich in carotenoids (leafy green vegetables, carrots, yams, sweet potatoes, squash, citrus fruits and tomatoes) along with supplementation seems to be just what the fountain of youth ordered. Flavonoids Flavonoids, a group of antioxidant plant pigments, seem to be able to protect specific organs. For instance, the flavonoids in milk thistle (Silybum marianum) have been used for ages for liver problems. Bilberry has been found protective for the eye and hawthorn for the heart and circulatory system. Numerous studies have shown the many beneficial effects of flavonoids with perhaps the best known being the ability of anthocyanidins in wine and grape seed extract to help protect your blood vessels and capillaries from oxidative damage (Phytotherapy 42, 1986: 11-14; Am J Clin Nutr 61, 1995: 549-54). Flavonoids are found in vegetables and such fruits as blackberries, blueberries, cherries and grapes. A diet rich in these foods helps ensure an adequate intake of these important nutrient compounds. Amino Acid Health Methionine and cysteine are sulphur containing amino acids (protein building blocks), both of which are essential in maintaining levels of glutathione, a substance that plays a major role in quelling free radicals. Studies have found that as we age, the level of these important amino acids in our bodies decreases. (NEJM 312 [1], 1985: 159-68). As it has been shown that adding cysteine to the diet of test animals can increase their life expectancy considerably, researchers believe these amino acids can help us live longer too. Attitude & Behavior Get more sleep! A recent study showed that men who habitually napped were less likely to have a heart attack. The men in this research who regularly napped for at least 30 minutes per day had about a 30% reduction in heart problems while those who napped for a full hour had a 50% reduction compared to non nappers. Naps of longer duration did not seem to increase the benefit. In the same research, investigators also found that spending time with a pet or merely contemplating nature could also improve cardiac health. Sensuality, optimism and altruism also appeared to have health benefits (Family Practice News, December 15, 1998: 14-15). In another study, this one in American Psychologist, researchers from the University of California found that people who are self-indulgent, pampered and achieve by running roughshod over the competition are less likely to outlive their healthy peers. Being egocentric, impulsive, undependable and tough-minded were predictors of poor physical health and a shorter life. So loosen up and be nice to your fellow humans! (U.C. Davis Magazine, Fall 1995: 14). Longevity at Last While no one has suggested that taking supplements, eating vegetables or exercising can, as of yet, extend the human life span past the generally recognized limit of about 120 years, researchers believe they can improve your odds of longer life. And by staying healthier, your old age will be more enjoyable, too.

Nutrients for Longevity by Edward C. Wallace, ND, DC Energy Times, September 1, 1999 What's the big deal about trying to live longer? As you grow older (and the American population grows older alongside you) you may want to postpone the inevitable. Few wish to hasten "the journey from which no tRAVELER returns." But as we approach that final bon voyage, chances are we desire clear sailing-aging without disability and with a peaceful easy feeling. How Do We Age Science has long puzzled about what causes the wrinkles, pains and deterioration of aging. In the search for causes, two basic theories have won over the most proponents: The first holds that cells are programmed with biological clocks that predetermine how many times they can reproduce before becoming non-functional. This theory has been largely formulated by the researcher Leonard Hayflick, MD. The second basic theory, introduced by Denham Harman, MD, PhD, in the mid 1950s, holds that cells eventually break down due to attack by caustic molecules called free radicals that cause oxidative stress. Programmed Cell Theory In the early '60s, Dr. Hayflick observed that human fibroblasts (cells from connective tissue) in the laboratory refused to divide more than about 50 times. Dr. Hayflick also found that even if he froze the fibroblasts after 20 divisions, they would remember that they only had 30 divisions left after thawing. Fifty cell divisions have been called the "Hayflick limit." Based on this research, scientists theorize that cells maintain a genetic clock that winds down as old age ensues. Many researchers believe the hypothalamus gland is the force behind our aging clocks, signaling the pituitary gland to release hormones that cause aging. Free Radical/Oxidative Stress Theory The other popular theory of aging pictures the human body as a cellular battlefield where attackers called free radicals damage our cells and tissues, making them age. In this scenario, a process called oxidation is the chief aging villain. On a microscopic level, oxidation generally entails molecules or atoms losing electrons. (Gaining electrons is called reduction.) The molecules or atoms that take these electrons are oxidizing agents. Free radicals are substances that can exist with missing electrons, making them readily able to donate or accept electrons and damage structures in cells. As such, they are highly reactive, binding with and destroying important cellular compounds. Most of the free radicals in your body are made during metabolic processes. More are added from the food you eat and environmental pollution. Most of these free radicals contain oxygen molecules. As each cell makes energy in little structures called mitochondria, free radicals result. These oxidant by-products can damage DNA, proteins and lipids (fats). Consequently, toxic by-products of lipid peroxidation may cause cancer, inhibit enzyme activity and produce mutations in genetic material that make you age faster. DNA Repair Theory Free radical damage to DNA can cause cells to mutate or die. Your body makes enzymes that can repair this damage and slow aging. But, over time, the amount of damage overwhelms the body's ability to fix things. As cells grow older, their ability to patch up DNA diminishes and the rate of damage proceeds faster than repair. The result: We age and eventually die. What Can We Do The free radical theory of aging suggests that taking antioxidants (compounds known to prevent free radical damage) in our food or as supplements may slow aging. In the publication Age (18 [51] 1995: 62), it was reported that "aging appears to be caused by free radicals initiated by the mitochondria at an increasing rate with age. Superoxide and hydrogen peroxide radicals formed by the mitochondria during normal metabolism are major risk factors for disease and death after about the age of 28 in developed countries. Antioxidants from the diet lower the production of free radicals without impairing essential reactions to maintain body function." Antioxidant Protection Common dietary antioxidants include: vitamins E and C, carotenes, sulphur containing amino acids, co-enzyme Q10 and flavonoids (a group of plant compounds or pigments responsible for the color in fruits and flowers). In addition, melatonin, DHEA and the amino acid compound glutathione may also prove of benefit. Glutathione along with the enzyme glutathione peroxidase are an essential part of free radical "quenching." (Quenching means changing free radicals into benign substances no longer capable of harm.) Deficiencies may suggest a decreased capacity to maintain detoxification and metabolic reactions in which glutathione plays a role, resulting in increased free radical stress and/or lipid peroxidation. Drinking too many alcoholic beverages can result in glutathione deficiency. In a study in which 39 healthy men and 130 healthy women between the ages of 20 and 94 were evaluated for glutathione levels, the older subjects had significantly decreased levels (especially in the 60 to 79-year-old group). The authors felt that physical health and longevity were closely related to glutathione levels (Jrnl Lab & Clin Sci 120(5), Nov. 1992: 720-725). Poor nutrition and/or deficiencies in essential micronutrients and many prescription medications may contribute significantly to detoxification capacity in an aged individual. All of these circumstances are common in the elderly. Eating a poor diet that contains too many processed foods without many fruits and vegetables can compromise your body's ability to detoxify pollutants, toxins and other harmful compounds. That can set off metabolic processes capable of fomenting large increases in free radical stress that can accelerate aging. Unfortunately, even in a country as prosperous as our own, nutrient deficiencies are frequent, especially in older citizens. Nutrition Deficiencies A study that looked at what elderly people consumed compared their reported intake with the 1989 Recommended Dietary Amount (RDA) and 1980 RDA: One of four people consumed only two-thirds of the RDA for calories and 60% consumed less than two-thirds of the RDA for vitamin D. As for other nutrients, 50% were found to have inadequate zinc levels (less than two-thirds of the RDA), 31% lacked calcium, 27% were short of vitamin B6, 25% didn't get enough magnesium, 7% missed out on folate and 6% ate less than two-thirds of the requirement for vitamin C (Nutrition Reviews (II), September 1995: S9-S15). When researchers examine what everyone in the U.S. eats, they find that only 9% of Americans consume the recommended five servings of fruits and/or vegetables per day (Proceedings of the National Academy of Sciences, Sept 1993). A diet high in fruits and vegetables is naturally high in antioxidant compounds and is believed to help you live longer. Unfortunately, if you buy your produce in the supermarket, those fruits and vegetables may also be rich in pesticide and herbicide residues (Consumer Reports, March 1999). Obviously, organic produce lacks these residues. But, in any case, research continues to indicate that a diet low in meats and animal fat and high in vegetables protects against antioxidant damage. Longevity Diets A six-year study of 182 people over age 70 in rural Greek villages found that those following their traditional diet of olive oil, whole grain breads, fresh fruits and vegetables and wine were less likely to die during the study than those who consumed more red meat and saturated fat. The most important foods in lowering the risk of early death included fruits, vegetables, legumes (peas and beans), nuts, dairy products and cereals (BMJ 311, 1995: 1457-1460) Another article in Epidemiology highlights the evidence that eating a vegetarian diet increases your chances of living longer. Included in this survey is a recent country-wide study of diet and health in China, showing that the traditional near vegetarian diet of 10% to 15% of calories coming from dietary fat reduced the chances of heart disease, diabetes and many types of cancers. (Epidemiology 3[5], 1992: 389-391). Staying Alive Staying skinny and limiting what you eat may also increase longevity. Scientific studies have previously shown that being overweight can theoretically curtail your life, increasing the risk of heart disease, diabetes and other life-shortening conditions. Animal studies have also shown that restricting food can slow diseases associated with aging. Researchers believe that cutting calories helps your immune system stay younger by reducing the formation of substances that are called proinflammatory cytokines. Specifically reducing your intake of fatty foods may decrease your chance of coming down with autoimmune diseases. Researchers think omega-6 fatty acid vegetable oils (like corn oil) may increase free radical formation and decrease levels of antioxidant enzyme messenger RNA in addition to other effects. (Nutrition Reviews 53[4], 1995: S72-S79). Another study found that cutting calories lowers the levels of oxidative stress and damage, retards age-associated changes and extends maximum life span in mammals (Science 273, July 5, 1996: 59-63). In yet another study, it was shown that caloric restriction early in the life of lab animals increased their life span by a whopping 40% (Australian Family Physician 23[7], July 1994: 1297-1305). Today's modern higher-fat, low-fiber diet with substantial sugar consumption represents everything the longevity researchers say you shouldn't eat. Longevity and Exercise: Exercise may slow aging.

An added benefit: By staying healthier, your old age won't only be longer, it will be more enjoyable, too. And, who knows, if you hang around long enough, taking your nutrients and getting a comfortable amount of consistent exercise, while meditating and refusing to succumb to stress, that magic bullet that will keep you alive for centuries may be discovered. Some day a new antioxidant or other substance may finally prove to provide the elusive fountain of youth. Stay tuned.
