Controlling Diabetes with Nutritional Supplements Perhaps no other disease is as closely linked to nutrition as diabetes. Not only doe nutrition play a role in its development, nutrition is also one of the disease’s most powerful treatments. Because of this strong and critical connection to nutrition, researchers have carefully studied the use of nutritional supplements in the treatment of the disease. They found that many vitamins, such as vitamin C and the B vitamins, minerals such as chromium, as well as herbs like Gymnema sylvestre, can safely, effectively, and naturally lower blood sugars and help prevent diabetic complications. What is even more important, however, is that these vitamins, minerals, and herbs can be combined together in a scientifically validated diabetic formula to work synergistically. That means their combined effectiveness is even more powerful. Like a group of good friends, these vitamins, minerals, and herbs do their best work when they are all together. In this issue of Ask the Doctor, we will talk about powerful vitamins, minerals, and herbs combined in a scientifically validated formula that people with diabetes can use every day. But before we get into the specific formula, we need to first talk about diabetes. Q. What exactly is diabetes? A. When we eat, the process of digestion breaks down our food into nutrients. Most of the food we eat is broken down into sugar (also called glucose). The sugar enters the bloodstream for delivery throughout the body and is then called blood sugar. Insulin, a hormone that helps metabolize blood sugar, is made in the pancreas-a long, Skinny gland located behind the stomach. Insulin takes blood sugar from the bloodstream and delivers it into the cells that make up the various organs in our body, such as our heart, lungs, and kidneys. The sugar provides energy to the cells to keep our hearts beating, our lungs breathing, and our kidneys excreting. Type 1 diabetes, sometimes called insulin-dependent or juvenile diabetes, most often starts in childhood. In this type of diabetes, the pancreas no longer makes insulin. The sugar stays in the blood instead of going into the cells where it is needed. Because of this, all people with Type 1 diabetes have to take at least one shot of insulin every day just to stay alive. Type 2 diabetes most often starts in adults and is also the most common kind. About 90 to 95 percent of all people with diabetes have Type 2. In Type 2 diabetes, the pancreas is usually producing enough insulin. However, the body does not use it effectively. The condition known as “insulin resistance” occurs when the cells do not respond to (resist) insulin’s attempt to enter with glucose. The pancreas responds by producing more and more insulin. When the cells do not respond, high levels of glucose build up in the blood, leading to Type 2 diabetes. Almost everyone with Type 2 diabetes also is insulin resistant. Because the insulin is left unused, the pancreas thinks it isn’t needed and may eventually stop making it. People with Type 2 diabetes often need to take prescription drugs to lower blood sugar levels if dietary and lifestyle changes are not enough to control the problem. In both types of diabetes, the sugar stays in the bloodstream instead of going into the cells where it is needed and belongs. When blood sugar builds up in the blood, it causes two problems. First, the cells become starved for energy. And, over a period of time, high blood sugar levels can damage the blood vessels, nerves, eyes, and kidneys. Q. What causes diabetes? A. While scientists aren’t exactly sure why Type 1 diabetes happens, they do know the immune system is involved. A healthy immune system protects us from diseases caused by infections, such as colds or the flu, as well as diseases that start in our own cells, such as cancer. For some reasons, in certain people, the immune system becomes confused and begins attacking and destroying the cells in the pancreas that makes insulin. Scientists aren’t exactly sure why Type 2 diabetes happens either; however, they have identified that it occurs most often in certain individuals. About 80 percent of people with type 2 diabetes are overweight, have high blood pressure, and have high cholesterol levels in their blood. Q. What are the symptoms of diabetes? A. Type 1 diabetes develops very quickly. The classic signs of diabetes include: -Frequent urination, because the body is trying to get rid of the excess sugar in the blood -Intense thirst, because the body needs to replace the fluid lost through the urine -Increased hunger, because the cells need nutrients -Weight loss, because without insulin, the body begins to starve The onset of Type 2 diabetes is often very gradual and may develop without any symptoms at all. Sadly, the diagnosis most often is made only after a complication of the disease happens. Q. What are the complications of diabetes? A. The complications of diabetes happen in both types of the disease. All diabetic complications are caused by chronically high blood sugars. The longer your blood sugar levels are elevated, the greater your chances are of having complications. Circulation problems High blood sugar damages blood vessels. When high levels of sugar are continuously in the blood, the blood vessels become thicker and less flexible, causing poor circulation. Poor circulation can impair healing, especially on the feet and lower legs. High blood sugar also causes higher levels of fat in the bloodstream. The fat clogs and narrows the blood vessels. Partial blockages deprive the heart of some necessary nutrients. A complete blockage can result in a heart attack, heart pain (called angina), or stroke. Nerve damage Nerve damage makes it hard for your nerves to send messages to the brain and other parts of the body. It may cause you to lose feeling in parts of your body or have a painful pins-and-needles-like feeling. While nerve damage most often affects the feet and legs, it can also affect other parts of the body. Eye problems Diabetes can damage and weaken the small blood vessels in the retina, the part of the eye that is sensitive to light and helps you see. When the blood vessels are weak, they can leak fluid, which causes swelling in the eye. The swelling blurs your vision. If the eye damage gets worse, your eye attempts to fix this damage by making new blood vessels over the retina. But because these blood vessels are fragile, they can break open easily and bleed into the eye. Scar tissue can then form. This may cause the retina to break away from the back of the eye, which can lead to visual impairment-even blindness. Kidney damage Diabetes can also damage the blood vessels in the kidney so it can’t filter out the body’s waste. High blood pressure is also associated with kidney damage. If you have diabetes and high blood pressure, it is important to keep them both under control as much as possible. The longer blood sugar levels are left uncontrolled, the greater the amount of kidney damage that can occur. If the kidney damage isn’t stopped, some individuals may progress to needing kidney transplants or dialysis machines. All of these complications, however, can almost always be prevented. Q. How can the complications of diabetes be prevented? A. Vitamins, minerals, and herbal supplements can provide powerful tools for preventing serious complications and keeping people with diabetes healthy. The best nutritional supplement contains powerful vitamins, minerals, and herbs in a synergistic formula that can effectively lower blood sugars and provide the specialized nutrients people with diabetes need. Q. Which vitamins, minerals, and herbs should be included in a nutritional supplement for people with diabetes? A. The vitamins, minerals, and herbs in a diabetic formula should work synergistically and be clinically demonstrated to help prevent the known complications of diabetes. To get the best results, it is very important that the right ingredients are in the diabetic formula you buy. Q. How often should I take a diabetic formula supplement? A. Read the label of the diabetic formula you are considering buying. Most quality products need to be taken twice a day. Keep in mind that you will still need to take a high quality multivitamin in addition to the diabetic formula supplement. A diabetic formula is complementary. That means that it is designed to be and addition to your multivitamin routine, not a replacement. Q. Could the diabetic formula lower my blood sugar level too much? A. In general, too low blood sugar levels should not be a problem. A high quality diabetic formula containing synergistic vitamins, minerals and herbs, most often lowers blood sugars to normal levels. However, these vitamins, minerals, and herbs will not excessively lower blood sugar levels that are already normal. Q. Do I need to continue monitoring my blood sugar when taking a diabetic formula supplement? A. Diabetes is a disease that requires active participation from you. You need to be aware of your problem and be in control of it as much as possible. If you use a home glucose monitor to check your blood sugars, you may feel more comfortable by checking your levels more frequently when you first take a diabetic formula supplement. You should always follow the recommendation of your doctor or a licensed health care practitioner regarding how often you should check your blood sugar levels. According to the American Diabetes Association (ADA) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) (as well as most licensed health care practitioners), a good blood sugar range for most people with diabetes (before a meal) is from about 70 to 150. An ideal range is 70-120. Taking a nutritional supplement formulated especially for diabetics that contain vitamins, minerals, and herbs that work synergistically in a scientifically valid formula will help you keep your blood sugars right where the Q. Can’t I just take the diabetic formula supplement and not worry about my diet? A. Unfortunately, you cannot. Successful diabetes management means doing lost of positive things. First, you need to see your licensed health care practitioner often. You need to choose foods wisely and stay active to have a positive influence on your blood sugar levels and your health. And, taking a diabetic formula supplement every day can really help. However, the diabetic formula supplement is meant to be an addition to your healthy diet, not a substitute. Conclusion Having diabetes might make you feel overwhelmed. Restrictions on what you may and may not eat might make you feel deprived and unfairly burdened. The possibility of disease complications may make you feel anxious and scared-even angry. It is only natural to ask “Why me?” Taking control of your diabetes, instead of letting it control you, can help with these feelings. Eating wisely and exercising every day are two important ways to improve your health. And, taking a nutritional supplement formulated specifically for people with diabetes every day can give you the critical control you need to direct your health for years to come. Many healthy years to come.

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.

June 14, 2005 12:09 PM
Building the Burn by Marjorie Flakowitz Energy Times, June 11, 2004 When was the last time you exercised? During the past decade, the number of obese Americans has jumped by 50%. A big factor in this increase: lack of physical activity. Today, technological society seems to make everyday life effortless: car windows retreat at the push of a button, remote controls keep couch potatoes from budging off the cushions and video games have replaced non-cyber ball playing. Americans don't move around and burn off the calories they eat. Instead, our sedentary ways are causing big stomach bulges and a big bulge in health problems linked to being overweight. Want to lose those pounds? Consuming the right nutrients and pounding the pavement are a great start. Number of Large Americans Grows Larger Fifty-five out of every 100 Americans are now overweight. And the numbers continue to surge. To take yourself out of these alarming statistics, plan a consistent exercise program. If the thought of sweating during strenuous workouts at the gym scares you, relax. You don't have to do that much. According to a long list of research, a few half-hour walks a week can put you on the road to weight loss. For instance, researchers at Duke found that walking a total of only 12 miles a week can help you control your weight even if you're not dieting (Archives of Internal Medicine 1/12/04). Of course dieting and taking the right supplements will help you lose weight a little faster, but walking burns off the pounds. In the study at Duke, scientists gathered about 180 overweight, sedentary people and assigned them to one of four groups. The first group had to jog about 20 miles a week. The second group jogged 12 miles a week. The third group walked 12 miles, and the last group didn't do a thing. " We found that the two low-exercise groups lost both weight and fat, while those in the more intensive group lost more of each in a 'dose-response' manner," says Cris Slentz, PhD, one of the researchers. " Simply put, the more you exercise, the more you benefit. Just as importantly, the control group of participants who performed no exercise gained weight over the period of the trial." Everybody who was exercising lost weight; their stomachs and hips shrank. The folks who did nothing didn't just stay at the same weight; their weight went up. Dr. Slentz adds, "From the perspective of prevention, it appears that the 30 minutes per day will keep most people from gaining the additional weight associated with inactivity. Given the increase in obesity in the US, it would seem likely that many in our society may have fallen below this minimal level of physical activity required to maintain body weight." Enzyme Help Of course, limiting the carbohydrates you consume and eating more protein at the same time as you exercise can help you lose weight more effectively. To help your body utilize protein more fully to fuel your exercise, many experts recommend taking enzyme supplements. One of the most valuable enzyme combinations in this process is Aminogen(r), an all-natural, patented plant enzyme that assists the digestive tract in liberating the amino acids that are the building blocks of dietary protein. By helping separate these amino acids, absorption is boosted through the walls of the small intestines and your metabolism is better able to take up proteins and use them. Add Chromium to Exercise The mineral chromium is another supplement found helpful in aiding weight loss. An eight-week study at the University of Texas, Austin, compared weight loss among obese women who exercised and took chromium with the number of pounds that were lost by women performing the same amount of exercise without taking supplements (Medicine & Science in Sports & Exercise 1997; 29:992-8). The result: women taking chromium lost a significantly greater amount. How does chromium work? A study at the University of Vermont found that chromium may help muscles take blood sugar (glucose) out of the blood more effectively by improving what's called insulin sensitivity (18th International Diabetes Federation Congress, Paris, 8/03). Sensitizing Insulin Insulin is released by the pancreas to help cells take in glucose. By exercising and keeping your weight down, and becoming more insulin sensitive, you potentially reduce your chances of getting diabetes. The cells quickly respond to insulin and blood sugar stabilizes. On the other hand, when insulin sensitivity drops significantly, the body may suffer what's called insulin resistance, a pre-diabetic condition that complicates and slows the removal of sugar from the blood. The Vermont researchers found that chromium increases the activity of a protein called Akt phosphorylation. This is a natural substance made by the body that makes cells more sensitive to insulin and speeds the movement of blood sugar into cells, where it can be burned for energy. So, in combination with exercise, which also helps the body become more responsive to insulin, chromium may help keep blood sugar under control. As Sandra Woodruff points out in her book Secrets of Good Carb, Low Carb Living (Avery/Penguin), "[P]hysical activity boosts the body's ability to process carbohydrate and helps reduce insulin resistance....Exercise acts much like an insulin-sensitizing drug to make the body's cells more responsive to insulin, which enables them to remove sugar from the blood more efficiently." The results of exercise and getting sufficient chromium can help support weight loss and healthy blood sugar levels. The Vermont research team found that the exercising chromium takers boosted their insulin sensitivity by almost 9%. Building a Lean Body A prime benefit of exercising while you lose weight is that physical activity builds muscle tissue. Muscle tissue, even at rest, burns more calories than fat cells, so having extra muscle means you can eat more and still maintain or lose weight. An aid in this process is Coleus forskohlii root, Benth., a plant that originated in India. Research shows that forskohlii furthers molecular energy processes within cells that support the development of lean body tissue (muscle) and the enzymatic reactions that break down fat. In a study of about two dozen women who took forskohlii extract, researchers found that taking this supplement was associated with feeling more energetic and less hungry (Experimental Biology meeting, 2002). According to Vladimir Badmaev, PhD, who has studied forskohlii, this herb's help in supporting lean body tissue is crucial to maintaining a healthy weight. " In highly overweight individuals, fat tissue can constitute up to 70% of body weight. The remaining proportion of body composition corresponds to the lean body mass. Lean body mass is composed of muscle, vital organs, bone, connective and other non-fatty tissues in the body," says Dr. Badmaev. " The body's metabolic rate is in direct proportion to the amount of lean body mass. Therefore, safely maintaining or increasing lean body mass is an important consideration for any weight-loss strategy." The Skinny on Calcium Calcium, long known for its ability to strengthen bones, is now turning out to play a key role in weight maintenance as well. In one study, obese mice who were put on calorie-restricted diets lost body fat when fed extra calcium (Experimental Biology meeting 2000). Both supplemental calcium and low-fat dairy proved effective. What's more, low-fat dairy's ability to burn fat and provoke fat loss have been confirmed in additional research (Obesity Research 4/04; 12:582-90). Fat cells contain calcium, and scientists believe that the more of this mineral a fat cell contains, the more fat will be burned off. This action is especially important when you cut back on calories, since that often gives your body the idea that it's starving, leading your metabolism to slow and making weight loss extremely difficult. A Complete Program To lose weight efficiently, stay in top shape and retain your feelings of energy, you also have to make sure you get enough of the vitamins and minerals necessary for good health. For those eating a high-protein diet who are limiting their fruits and vegetables, taking a supplement that incorporates nutrients from fruits and vegetables can help restore your feelings of well-being and help maintain your motivation for dieting and losing weight. (Supplements are available that deliver these nutrients without carbohydrates.) In addition, supplements of what are called ketogenic amino acids-the natural substances that form protein's building blocks-can also help fuel your weight-loss program. These special nutrients can be efficiently used for the body's energy needs, a process that helps you lose weight. And don't forget to keep moving! Soon you may have the kind of results researchers produced at the University of Pittsburgh when they studied women who exercised 40 minutes, five times a week (Journal of the American Medical Association 9/10/03). Those women lost 25 pounds in six months. Your results may be just as good or better!

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.
