Iron. Iron deficiency is the most common micronutrient deficiency in the US, especially among women of childbearing age, and “has been associated with poor child development after birth along with increased risk of miscarriage and premature delivery,” according to Higdon. “Also, if you’re deficient you’ll get really tired-you get less oxygen delivered to your tissues an the baby’s” A supplement should supply 30mg; vegetarians have to pay particular attention to their iron levels. Eating foods rich in vitamin C can make it easier to absorb iron, as can eating such fermented soy goodies as tempeh and miso.
-Calcium. Building baby’s bones requires plenty of calcium; Jones and Hudson recommend getting 1200mg a day. If you are lactose intolerant-that is, you can’t properly digest milk products-they suggest you “try yogurt made with live active cultures, whose bacteria releases lactose-digesting enzymes.” Supplemental calcium is another option, preferably in gluconate or chelate form for better absorption. (Calcium can also help cut the leg cramps caused by the pressure of a growing baby.)
-Vitamin D. It doesn’t matter how much calcium you take if you’re not getting enough of the vitamin D that lets your body utilize calcium properly. “Vitamin D deficiency is increasingly common,” says Higdon, “and the RDIs (Reference Daily Intakes) might not be high enough for people who don’t get sun exposure.” Spending 15 minutes a day in the sun can restore your body’s supplies, but “the farther north you live, the longer that period in the winter you can’t make vitamin D, and it’s actually not in too many foods.” Taking 400 IU daily can make up the shortfall.
Believe it or not, iodine deficiency is a growing concern in the US as people cut back on salt, which is commonly fortified with iodine. Higdon says that most prenatal vitamins contain 150mcg.

Subject: Anti-Aging Nutrients
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.

Nutritional Scorecard

Subject: Nutritional Scorecard
Nutritional Scorecard by Sylvia Whitefeather Energy Times, June 15, 2004
For over 50 years, the federal government has produced Recommended Daily Allowances (RDAs) as guidelines for vitamin and mineral intake. Then, in 1993, the Reference Daily Intakes (RDIs) superseded the RDAs. By applying this new designation, the government's guidelines are now supposed to represent the designated amounts that an average person should consume. With this in mind, and the fact that many experts think you should consume more than some of the RDIs, how does your nutritional scorecard add up? Answering a few nutritional questions can point you in the right direction.
Perfect Protein
Are you trying to lose weight? If you are, the latest thinking on weight loss opines that eating more protein may be the key to keeping your weight down. Two recent studies published in the Annals of Internal Medicine (5/18/04) found that people who ate a low-carbohydrate, high-protein diet lost more weight and had better cholesterol levels than dieters who ate fewer fatty foods. Both studies found that a low-carb diet can improve your triglycerides (blood fats) and boost your HDL, or good, cholesterol.
Eating protein satisfies both tummies and taste buds. Researchers have found that the amount of protein eaten in a meal determines not only how much food you eat but also how satisfied you feel after eating (J Nutr 2004 Apr; 134(4):974S-9S). And when you feel satisfied after eating less food you improve your odds of losing weight.
We need about 50 grams of protein a day to support the body's functions. The best sources of protein are eggs, meat, milk, protein shakes and yogurt.
Classy Carbohydrates
Does your energy level go up and down during the day? To get off the energy rollercoaster, cut down on carbohydrates, and make sure the carbs you do eat are complex.
Carbohydrates have been getting some unflattering press lately. Yes, if you want to lose weight, you may want to go on a strictly low-carb diet. But for those not concerned with weight, carbohydrates are the principle source of energy for the body.
What's more, even if you do restrict carbohydrates, you should still eat a tiny bit of them. Without some carbs in the diet your body cannot regulate protein or fat metabolism. According to Michael and Mary Eades, MD, authors of The 30-Day Low-Carb Diet Solution (Wiley), "Carbohydrates control insulin and insulin controls your metabolic health."
So, make your carbohydrates count. Indulge in complex carbohydrates: whole grains, fruits and vegetables. In those foods, carbs are accompanied by fiber and larger amounts of vitamins and phytonutrients. Other reliable sources of complex carbohydrates are whole wheat bread, brown rice and oatmeal.
Fabulous Fiber
Are you concerned about your heart health? Fiber from beans, oats, legumes, nuts, rice bran, fruits and vegetables helps stabilize blood sugar and reduce cholesterol. Pectins, found in apples, pears, prunes and plums, are a particularly useful form of water-soluble fiber.
Insoluble fiber, in cereals, wheat bran and vegetables, reduces the risk of colon-related problems. In addition to adding fiber to the diet, dried beans and soybeans have been shown to lower cholesterol, improve vascular health and kidney functioning, preserve bone mineral density and reduce menopausal discomforts (AJCN 1999 Sept; 70(3 suppl):464S-74S). Fiber also promotes good bowel health and encourages the growth of beneficial intestinal flora.
You need 25 to 40 grams of fiber daily. If you have cut back on your carbohydrates, be sure to take a reliable fiber supplement.
Fantastic Fats
Do you have problems focusing on mentally challenging tasks? If so, you should eat more fish and get more of the omega-3 fatty acids that fish and flax contain. Higher levels of this type of fat have been linked to better concentration while performing demanding intellectual work (Lipids 2004 Feb; 39(2):117-23).
Fats add flavor to food, making meals taste better. Monounsaturated fats like plain olive oil and canola are liquid at room temperature and are suitable for use in cooking at high temperatures. Researchers have found that a diet high in monounsaturated fat has the ability to decrease LDL (bad) cholesterol (J Nutr 2001; 131:1758-63). Other fats, such as extra virgin olive oil and flaxseed oil, are best used in dishes that don't need cooking, such as salads.
Although the RDI for fat is less than 30% of the total calorie intake, some researchers believe that if you eat healthy fat, eating too much is not a concern. Omega-3 fats are available in supplement form.
Wonderful Water
Do you suffer from dry skin? You may not be drinking enough water. This precious liquid is used by every cell of our bodies and makes up 60% to 75% of our body weight. Water is important for kidney function. Researchers in Italy found that drinking adequate amounts of water can help prevent the formation of kidney stones (Urol Int 2004; 72 Suppl 1:29-33).
Your activity level, environment and diet influence how much water you need daily. Try to drink at least eight cups of fluid a day from noncaffeinated, nonalcoholic sources.
Voluptuous Vitamins
Do you exercise frequently? If you do, you need more antioxidant vitamins like natural vitamin E and vitamin C as well as a healthy supply of carotenoids. A study at the School of Applied Medical Sciences and Sports Studies, University of Ulster, found that exercisers need more antioxidants. Otherwise, their exertion may release an excess number of free radicals (caustic molecules) in their bodies and do damage to the heart arteries and other internal organs.
Vitamins, in general, are defined as micronutrients that are necessary for life. They are necessary for the production of energy, a healthy immune system and hundreds of other functions in the body.
Vitamins aren't the only substances that produce big benefits in small quantities. Phytonutrients are chemicals in plants that have health-promoting properties. These nutrients are getting more and more attention from researchers who are keeping score on our nutritional requirements.
Mineral Crunch
Do your meals contain plenty of calcium? If not, you may need supplements to keep your bones strong and help keep your weight down. One study, presented at the Experimental Biology 2003 meeting in San Diego, found that young women who consumed more calcium had better luck controlling their weight. In this research, it didn't take much calcium to make a difference in waistlines. Consuming just one more serving daily (a cup of milk or a thumb-sized piece of cheese, each of which contain about 300 mg of calcium) made, on average, about a two-pound difference.
In addition, many experts recommend multimineral supplements (along with multivitamins) to promote better health. A recent study of people with immune problems, for instance, found that those kinds of supplements seem to help boost the immune system (AT News 2004 Feb 27; 398:4-5).

Menopause: Disease or Condition?

Menopause: Disease or Condition?
by Mary Ann Mayo & Joseph L. Mayo, MD Energy Times, September 4, 1999
It's front-page news. It's politically correct and socially acceptable. Talking about menopause is in. Suddenly it's cool to have hot flashes. Millions of women turning 50 in the next few years have catapulted the subject of menopause into high-definition prominence.
It's about time. Rarely discussed openly by women (what did your mother ever advise you?), meno-pause until recently was dismissed as "a shutting down experience characterized by hot flashes and the end of periods." Disparaging and depressing words like shrivel, atrophy, mood swings and melancholia peppered the scant scientific menopausal literature.
What a difference a few years and a very vocal, informed and assertive group of Baby Boomers make. Staggered by the burgeoning numbers of newly confrontational women who will not accept a scribbled prescription and a pat on the head as adequate treatment, health practitioners and researchers have been challenged to unravel, explain and deal with the challenges of menopause.
Not An Overnight Sensation
Menopause, researchers have discovered, is no simple, clear cut event in a woman's life. The "change of life" does not occur overnight. A woman's body may begin the transition toward menopause in her early 40s, even though her last period typically occurs around age 51. This evolutionary time before the final egg is released is called the perimenopause. Erratic monthly hormone levels produce unexpected and sometimes annoying sensations.
Even as their bodies adjust to lower levels of estrogen, progesterone and testosterone, some women don't experience typical signs of menopause until after the final period. A fortunate one-third have few or no discomforts.
Hormonal Events
According to What Your Doctor May Not Tell You About Premenopause (Warner Books) by John R. Lee, MD, Jesse Hanley, MD, and Virginia Hopkins, "The steroid hormones are intimately related to each other, each one being made from another or turned back into another depending on the needs of the body...But the hormones themselves are just part of the picture. It takes very specific combinations of vitamins, minerals and enzymes to cause the transformation of one hormone into another and then help the cell carry out the hormone's message. If you are deficient in one of the important hormone-transforming substances such as vitamin B6 or magnesium, for example, that too can throw your hormones out of balance. Thyroid and insulin problems, toxins, bad food and environmental factors, medication and liver function affect nutrient and hormone balance."
The most important reproductive hormones include:
Estrogen: the female hormone produced by the ovaries from puberty through menopause to regulate the menstrual cycle and prepare the uterus for pregnancy. Manufacture drops significantly during menopause. Estradiol is a chemically active and efficient form of estrogen that binds to many tissues including the uterus, breasts, ovaries, brain and heart through specific estrogen receptors that allow it to enter those cells, stimulating many chemical reactions. Estriol and estrone are additional forms of estrogen.
Progesterone: also produced by the ovaries, it causes tissues to grow and thicken, particularly during pregnancy, when it protects and nurtures the fetus. Secretion ceases during menopause.
Testosterone: Women produce about one-twentieth of what men do, but require it to support sex drive. About half of all women quit secreting testosterone during menopause.
Estrogen's Wide Reach
Since estrogen alone influences more than 400 actions on the body, chiefly stimulating cell growth, the effects of its fluctuations can be far-reaching and extremely varied: hot (and cold) flashes, erratic periods, dry skin (including the vaginal area), unpredictable moods, fuzzy thinking, forgetfulness, fatigue, low libido, insomnia and joint and muscle pain.
Young women may experience premature menopause, which can occur gradually, as a matter of course, or abruptly with hysterectomy (even when the ovaries remain) or as a result of chemotherapy. Under such conditions symptoms can be severe.
In the 1940s doctors reasoned that if most discomforts were caused by diminishing estrogen (its interactive role with progesterone and testosterone were underestimated), replacing it would provide relief. When unchecked estrogen use resulted in high rates of uterine cancer, physicians quickly began adding progesterone to their estrogen regimens and the problem appeared solved.
For the average woman, however, hormone replacement therapy (HRT) became suspect and controversial, especially when a link appeared between extended use of HRT (from five to 10 years) and an increase in breast and endometrial cancers (Journal of Clinical Pharmacology 37, 1997). The result: Women have drawn a line in the sand between themselves and their doctors.
Resolving The Impasse
Since hormone replacement reduces the risk of major maladies like heart disease, osteoporosis, Alzheimer's, colon cancer and diabetes that would otherwise significantly rise as reproductive hormone levels decrease, most doctors recommend hormone replacement shortly before or as soon as periods stop. Hormone replacement also alleviates the discomforts of menopause.
But only half of all women fill their HRT prescriptions and, of those who do, half quit within a year. Some are simply indifferent to their heightened medical risks. Some are indeed aware but remain unconvinced of the safety of HRT. Others complain of side effects such as bloating, headaches or drowsiness.
Women's resistance to wholesale HRT has challenged researchers to provide more secure protection from the diseases to which they become vulnerable during menopause, as well as its discomforts. If the conventional medical practitioners do not hear exactly what modern women want, the complementary medicine community does. Turning to centuries-old botanicals, they have validated and compounded them with new technology. Their effectiveness depends on various factors including the synergistic interaction of several herbs, specific preparation, the correct plant part and dosage, harvesting and manufacturing techniques.
Research demonstrates that plant hormones (phytoestrogens) protect against stronger potentially carcinogenic forms of estrogen while safely providing a hormone effect. Other herbs act more like tonics, zipping up the body's overall function.
Help From Herbs
Clinical trials and scientific processing techniques have resulted in plant-based supplements like soy and other botanicals that replicate the form and function of a woman's own estrogen.
The complementary community also can take credit for pushing the conventional medical community to look beyond estrogen to progesterone in postmenopausal health.
Natural soy or Mexican yam derived progesterone is formulated by pharmacologists in creams or gels that prevent estrogen-induced overgrowth of the uterine lining (a factor in uterine cancer), protect against heart disease and osteoporosis and reduce hot flashes (Fertility and Sterility 69, 1998: 96-101).
A quarter of the women who take the popularly prescribed synthetic progesterone report increased tension, fatigue and anxiety; natural versions have fewer side effects.
These "quasi-medicines," as Tori Hudson, a leading naturopathic doctor and professor at the National College of Naturopathic Medicine, Portland, Oregon, calls them, are considered "stronger than a botanical but weaker than a medicine." (Hudson is author of Gynecology and Naturopathic Medicine: A Treatment Manual.)
According to Hudson, the amount of estrogen and progesterone in these supplements is much less than medical hormone replacement but equally efficacious in relieving menopausal problems and protecting the heart and bones.
According to a study led by Harry K. Genant, PhD, of the University of California, San Francisco, "low-dose" plant estrogen derived from soy and yam, supplemented with calcium, prevents bone loss without such side effects as increased vaginal bleeding and endometrial hypoplasia, abnormal uterine cell growth that could be a precursor to endometrial cancer (Archives of Internal Medicine 157, 1997: 2609-2615).
These herbal products, including natural progesterone and estrogen in the form of the weaker estriol or estrone, may block the effect of the stronger and potentially DNA-damaging estradiol.
Soy in its myriad dietary and supplemental forms provides a rich source of isoflavones and phytosterols, both known to supply a mild estrogenic effect that can stimulate repair of the vaginal walls (Journal of the National Cancer Institute 83, 1991: 541-46).
To enhance vaginal moisture, try the herb cimicifuga racemosa, the extract of black cohosh that, in capsule form, builds up vaginal mucosa (Therapeuticum 1, 1987: 23-31). Traditional Chinese herbal formulas containing roots of rehmannia and dong quai have long been reputed to promote vaginal moisture.
Clinical research in Germany also confirms the usefulness of black cohosh in preventing hot flashes and sweating, as well as relieving nervousness, achiness and depressed moods caused by suppressed hormone levels. It works on the hypothalamus (the body's thermostat, appetite and blood pressure monitor), pituitary gland and estrogen receptors. Green tea is steeped with polyphenols, mainly flavonoids, that exert a massive antioxidant influence against allergens, viruses and carcinogens. The risks of estrogen-related cancers such as breast cancer are particularly lowered by these flavonoids, as these substances head directly to the breast's estrogen receptors. About three cups a day exert an impressive anti-inflammatory, antiallergenic, antiviral and anticarcinogenic effect.
Other phytoestrogen-rich botanicals, according to Susun Weed's Menopausal Years: The Wise Woman Way (Ash Tree Publishing), include motherwort and lactobacillus acidophilus to combat vaginal dryness; hops and nettles for sleep disturbances; witch hazel and shepherd's purse for heavy bleeding; motherwort and chasteberry for mood swings; dandelion and red clover for hot flashes.
Our Need For Supplements
Adding micronutrients at midlife to correct and counter a lifetime of poor diet and other habits is a step toward preventing the further development of the degenerative diseases to which we become vulnerable. At the very minimum, you should take:
a multivitamin/mineral supplement vitamin E calcium
Your multivitamin/mineral should contain vitamins A, B complex, C, D, E, calcium, magnesium, potassium, copper and zinc. Look for a wide variety of antioxidants that safeguard you from free radical damage, believed to promote heart disease and cancer, as well as contribute to the aging process.
Also on the list: mixed carotenoids such as lycopene, alpha carotene and vitamin C; and folic acid to help regulate cell division and support the health of gums, red blood cells, the gastrointestinal tract and the immune system.
Studies indicate a deficiency of folic acid (folate) in 30% of coronary heart disease, blood vessel disease and strokes; lack of folate is thought to be a serious risk factor for heart disease (OB.GYN News, July 15, 1997, page 28).
Extra vitamin E is believed to protect against breast cancer and bolster immune strength in people 65 and older (Journal of the American Medical Association 277, 1997: 1380-86). It helps relieve vaginal dryness, breast cysts and thyroid problems and, more recently, hit the headlines as an aid in reducing the effects of Alzheimer's and heart disease. It is suspected to reduce the thickening of the carotid arterial walls and may prevent the oxidation of LDL (bad) cholesterol, which contributes to the formation of plaque in arteries.
Selenium also has been identified as an assistant in halting cancer (JAMA 276, 1996: 1957-63).
The Omegas To The Rescue
Essential fatty acids found in cold water fish, flaxseed, primrose and borage oils and many nuts and seeds are essential for the body's production of prostaglandin, biochemicals which regulate hormone synthesis, and numerous physiological responses including muscle contraction, vascular dilation and the shedding of the uterine lining. They influence hormonal balance, reduce dryness and relieve hot flashes.
In addition, the lignans in whole flaxseed behave like estrogen and act aggressively against breast cancer, according to rat and human studies at the University of Toronto (Nutr Cancer 26, 1996: 159-65).
Research has demonstrated that these omega-3 and omega-6 fatty acids can reverse the cancer-causing effects of radiation and other carcinogens (Journal of the National Cancer Institute 74, 1985: 1145-50). Deficiencies may cause swelling, increased blood clotting, breast pain, hot flashes, uterine and menstrual cramps and constipation. Fatigue, lack of endurance dry skin and hair and frequent colds may signal EFA shortage. Plus, fatty fish oils, along with vitamin D and lactose, help absorption of calcium, so vital for maintaining bone mass.
In addition, studies show that the natural substance Coenzyme A may help menopausal women reduce cholesterol and increase fat utilization (Med Hyp 1995; 44, 403, 405). Some researchers belive Coenzyme A plays a major role in helping women deal with stress while strengthening immunity.
Still Suffering?
Can't shake those menopausal woes? Menopause imposters may be imposing on you: The risk of thyroid disease, unrelenting stress, PMS, adrenal burnout, poor gastrointestinal health and hypoglycemia all increase at midlife. Menopause is a handy hook on which to hang every misery, ache and pain but it may only mimic the distress of other ailments. For this reason every midlife woman should have a good medical exam with appropriate tests to determine her baseline state of health. Only with proper analysis can you and your health practitioner hit on an accurate diagnosis and satisfying course of therapy.
And if menopause is truly the issue, you have plenty of company. No woman escapes it. No woman dies from it. It is not a disease but a reminder that one-third of life remains to be lived. Menopausal Baby Boomers can anticipate tapping into creative energy apart from procreation. If not new careers, new interests await. An altered internal balance empowers a menopausal woman to direct, perhaps for the first time, her experience of life. She has come of age-yet again. Gone is the confusion, uncertainty, or dictates of a hormone driven life: This time wisdom and experience direct her. There is no need to yearn for youth or cower at the conventional covenant of old age. Menopause is the clarion call to reframe, reevaluate and reclaim.

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. 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 living longer. 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.

Drinks Everywhere
by John Olan Energy Times, January 7, 2002
Water keeps you alive. About 50% to 70% of your cells are made of water. So when you talk about drinks, you're talking about water plus... But, oh, what a plus!
While water is crucial for survival, those pluses can add a waterfall of desirable ingredients to your diet, health and beverage indulgence. Even though water is the basic ingredient when you need a drink, healthy drinking has come to mean much more than H2O. The drink scene has bubbled up to include a new universe of usual and unusual liquids. When your thirst bursts upon the scene, you now have a tremendous choice of ways to quench.
Soy Drinks
The soy revolution in American nutrition has convincingly attacked the drink world. No matter what your age, nutritional requirements or taste preferences, it seems as though someone, somewhere, has designed a soy drink with you in mind. The most convincing health benefit of soy and soy drinks is its boost to heart health. Since 1999, the Food and Drug Administration has allowed soy drinks (and other soy products) to list soy's heart benefits. In so doing, the FDA reviewed 27 studies that demonstrated soy protein could help lower total cholesterol and LDL, the so-called bad cholesterol that can significantly raise heart disease risk. To be allowed the heart disease benefit on their labels, drinks, or other foods, must contain at least 6.25 grams of soy protein per serving, contain less than 3 grams of fat, less than a gram of saturated fat, less than 20 mg of cholesterol and not much salt. According to the FDA, if you consume four daily servings of soy, you can drop your LDL by up to 10%. That's great for heart health: each 1% reduction in total cholesterol can mean about a 2% drop in your risk of heart disease. The key research the FDA looked at included a two month study at Wake Forest University Baptist Medical Center that showed soy can help reduce your total cholesterol and LDL cholesterol without lowering your HDL. HDL, the so-called "good" cholesterol, protects heart health and keeps your heart disease risk down (Arch Int Med, 9/27/99). Meanwhile, another study published in the New England Journal of Medicine (8/3/95) found that soy produces "significant reductions" in cholesterol, LDL and triglycerides, blood fats that can otherwise put your cardiovascular sysem at risk. Isoflavones, natural chemicals found in soy, are phytoestrogens, a weak form of estrogen that is believed by many researchers to produce health benefits. Some studies show that by producing what's called a "weak estrogenic effect," these chemicals may prevent the body's own estrogen from initiating cancer. While studies exist supporting these effects, this claim for cancer prevention is still controversial. A study of Asian women who moved to the United States found that the more soy they ate, the less their risk of breast cancer (Second Intl Symp on Soy and Tr Chron Dis 9/15/96). In any case, soy protein provides complete protein: all the amino acids, or protein building blocks, that the body needs to form its own proteins are found in soy. All of this good soy news has sent sales of soy drinks and other soy foods soaring. While sales of soy foods reached a little more $850 million in 1992, by next year they are expected to climb to well over $3.7 billion. Multivitamin Water For vitamin takers on the run, water is now available fortified with a wide collection of micronutrients. The key benefit: possible health enhancement by supplying vitamins your diet may omit. As Walter Willet, MD, points out in Eat, Drink and Be Healthy (Simon & Schuster), "research is pointing ever more strongly to the fact that several ingredients in a standard multivitamin.... are essential players in preventing heart disease, cancer, osteoporosis and other chronic disease... It's the best nutritional bang for your buck." In a Russian study, a group of children, aged four to 14, with gastrointestinal diseases were fed multivitamin-infused drinks and beta carotene. The children experienced vast improvements, leading researchers to suggest fortifying the diets of folks suffering from gastrointestinal diseases with vitamin-containing drinks.
Green with Health
Everyone from mom to the US surgeon general tells you to eat dark green vegetables every day. The truth is, many of us just don't do it. Spirulina, wheat grass, barley grass and chlorella are often referred to as "green foods." Spirulina, a popular food supplement in Japan, is a vitamin and mineral powerhouse available in the US in powder and ready-to-drink shakes. Rich in protein, spirulina contains chlorophyll, carotenoids, minerals, gamma-linolenic acid (GLA) and unique pigments called phycobilins (PDR For Nutritional Supplements, Medical Economics). It's these same healthful pigments that give spirulina its blue/green color. In studies, spirulina has been shown to possess antiviral, antioxidant, anti-allergic and immune-boosting properties (Free Rad Biol Med. 2000; 28:1051-1055; Biochem Pharmacol 1998; 55:1071-1076; Inflamm Res 1998; 47:36-41; Spirulina platensis 1996; 59:83-87). Evidence exists that spirulina may favorably affect immune functions, inhibit some allergic reactions and lower cholesterol. Blended into shakes and drinks, spirulina can add a healthful boost to your day. Now, when Aunt May asks if you've had your green vegetables, just lift your glass, look her in the eye, tell her yes and mean it.

Subject: GlucosaMend™ Tissue/Joint Repair Complex
GlucosaMend
More than 40 million Americans experience joint discomfort. But exciting new research proves you can do something about it. Our health and well-being is inextricably linked to lifestyle choices: the right combination of exercise, weight training and supplementation can strengthen muscles and joint tissues to minimize stress and degradation. Targeted nutrition to the multiple body systems related to joint and connective tissue can help maintain flexibility and joint comfort. GLUCOSAMEND supports the musculoskeletal system with structural building blocks and tissue production cofactors, as well as aiding the body’s mechanisms for soothing relief and antioxidant defense.
Bio-Aligned Formula™ GLUCOSAMEND is uniquely effective because it is a Bio-Aligned Formula. Source Naturals evaluates the underlying causes of system imbalances. Then we design formulas that provide targeted nutrition to bring your interrelated body systems back into balance.
Musculoskeletal System—Structural Building Blocks
Certain building blocks of joints and connective tissue can help maintain joint integrity and comfort. Glucosamine is a major constituent of glycosaminoglycans, which in turn form proteoglycans, molecules that hold and bind the water that lubricates joints, disperses stress and nourishes joint tissue. The amino acids proline and lysine are structural components of collagen and elastin, which give strength to connective tissue. GLUCOSAMEND contains glucosamine sulfate, N-acetyl glucosamine, proline and lysine.
Musculoskeletal System—Tissue Production Cofactors
Some micronutrients are necessary as cofactors in the production of connective tissue. For example, vitamin C and copper help form hydroxyproline and hydroxylysine, main constituents of collagen. A unique property of grape seed extract is its ability to form a bond between broken collagen fibers, helping to repair them and restore flexibility and strength to connective tissues and joints. GLUCOSAMEND provides vitamin C, zinc, manganese, copper, and grape seed extract to address these cofactors.
Soothing Relief Mechanisms
Some herbs and nutrients have the capacity to support the body’s natural mechanisms for increasing comfort. Boswellia, for example, is an herb with soothing properties, while vitamin B-6 helps to stabilize collagen and elastin. Additional herbs and nutrients, acting in conjunction with antioxidant protectors, support tissue comfort and health. GLUCOSAMEND contains Boswellia serrata, quercetin, copper, and vitamin B-6.
Antioxidant Defense
The health and integrity of joints and tissues—specifically of cell membranes— is supported by botanicals and nutrients that support the body’s natural antioxidant response. When tissues become damaged, the body mounts a repair process that ultimately generates free radicals. These free radicals can also break down healthy cells and tissues in the process, hence the need for antioxidants to neutralize and break the cycle. GLUCOSAMEND provides grape seed extract, vitamin C, zinc, selenium, copper, quercetin to neutralize free radicals.
Lifestyle Tips for Healthy Joints: A Strategy for WellnessSM
Healthy lifestyle habits should be part of your individual strategy for joint wellness. Source Naturals believes in a holistic approach to living. Not only can supplements bring balances to your individual body systems but certain lifestyle choices can also bio-align your health. Exercise Regularly: Regular physical activity helps lubricate cartilage, strengthens muscles around joints, and promotes weight control. An exercise program geared to joint health includes stretching, mild weight training, and low-impact aerobics. Watch Your Weight: Population-based studies, including the well-known Framingham study, have consistently shown a link between obesity and challenges to joint health. Excess weight causes pressure on joints, and can speed the rate at which cartilage wears down. Eat Healthy: To support healthy joints, increase your intake of omega-3 fatty acids from salmon, sardines, flax seeds or flax oil, avoid excess protein intake, and replace animal with plant proteins when possible. You should also eat lots of organically grown fruits and vegetables, limit saturated fat and eliminate hydrogenated oils. Rest and Relaxation: Regularly scheduled rest gives your body time to recover and rebuild, allowing you to make the most of your exercise program. It’s important to know when to slow down. Supplementation: Source Naturals offers a range of products that can supplement your strategy for joint wellness. These include the pineapple enzyme BROMELAIN; SAME, a natural compound formed from the amino acid methionine, which has been found to support joint comfort and mobility; and CHONDROITIN to promote water retention and elasticity in cartilage and inhibit enzymes that break down cartilage.
