Antioxidants, including nutrients such as vitamin C, vitamin E, beta carotene, and selenium, neutralize free radicals and stop oxidative chain reactions, limiting cellular damage. Evidence that these nutrients work to prevent or reduce the risk of disease is accumulating. More than 100 dietary studies have found that people who eat large amounts of fruits and vegetables with beneficial antioxidants have a reduced risk of cancer and heart disease. Antioxidant nutrients may also be an important key to longevity. An Italian study, published in the Journal of the American Geriatric Society, found that centenarians ate more vegetables and showed less oxidative stress—lower levels of fatty acids and glucose in their blood and lower levels of free radical activity—than younger study participants. Another study, by researchers at the National Institute on Aging, found that older people who took vitamin C and vitamin E supplements were 42 percent less likely to die of any cause during the three-year study period than were those who used neither supplement. But the final word isn't in about antioxidants. Some studies have indicated that antioxidant supplements can actually have a negative effect on the body. The National Cancer Institute halted a major study ahead of schedule because study participants taking beta called phytonutrients. There is little evidence that these plant-derived supplements are better, however. Thousands of plants can be used, and no one knows what the best ones are for individual vitamins. Hormones and Nutritional Supplements Know the Role of Hormone Replacements. Although the search for the mythical fountain of youth ended centuries ago, the search for a magic potion to counteract the aging process and extend life continues today. Hormone supplements ranging from estrogen and testosterone to DHEA and melatonin are among the latest of these magic potions. Contrary to popular claims, though, none of these hormones has been shown to prevent or reverse aging, according to the National Institute on Aging (NIA).Although some hormones, such as estrogen and testosterone, do have proven health benefits and research may ultimately reveal important health benefits from others, the NIA urges consumers to use caution in taking hormone supplements to combat aging. Hormone supplements are powerful chemicals that enter the bloodstream and travel throughout the body. Tiny amounts may have far-reaching effects, and unsupervised use of any hormone supplement, in any amount, can lead to health problems. Three of the "antiaging hormones"—estrogen, testosterone, and human growth hormone—are available only by prescription, but DHEA and melatonin are available over the counter and are unregulated by the Food and Drug Administration. |
