Ageing
Many people live well into their 80s and beyond. As the body ages, various systems slow down, and the risk of disease increases. You cannot halt the progress of time, but you can forestall some of the negative effects of ageing with a healthy lifestyle and well chosen supplements. What It Is.Put simply, ageing is the process of growing old. Every part of the body is affected. Among other changes, hair turns grey, skin wrinkles, joints and muscles lose flexibility, bones become weak, memory declines, eyesight diminishes and immunity is impaired. What Causes it?The process of cell division and replacement that continues throughout life slows down with advancing age, and a progressive deterioration of all body systems begins. Though some decline is normal and inevitable, many researchers believe that unstable oxygen molecules called free radicals accelerate the process, making some people old before their time. A certain amount of damage is unavoidable because free radicals are produced during the normal course of cell activity, but it may be possible to slow down ageing by avoiding outside factors that foster free-radical formation - e.g. cigarette smoke, pollution, excessive alcohol, and radiation from X-rays or the sun and by enhancing the body's own antioxidant defences. Manufactured by the cells and obtained through diet, antioxidants are powerful weapons that can disarm free radicals. How Can Supplements Help?Some supplements should be used daily by everyone concerned about the effects of ageing. Vitamin C and vitamin E are antioxidants that fight free radicals. Vitamin C and flavoniods work within the cells' watery interiors. Vitamin E protect the fatty membranes that surround cells; in addition, it improves immune function in older people and reduces the risk of some age-related conditions, including heart disease, some forms of cancer and, possibly, Alzheimer's disease. Green tea extract - which has long been prized for its longevity-promoting properties, and grape seed extract (100mg twice a day) are other antioxidants that may be more potent than Vitamin C and E. Folic acid, a B vitamin, maintains red blood cells and promotes the healthy functioning of nerves. Moreover, it protects the heart by helping the body process homocyteine, and amino acid-like compound that may raise the risk of heart disease.
Folic acid is assisted by vitamin B12 which fosters healthy brain function. Vitamin B12 supplements are useful for older people because many of them lose the ability to absorb the vitamins from food, and low B12 levels can cause nerve damage and dementia. It is probably best to take B vitamins in the for of an 'A to Z' multivitamin and mineral formulation; these have been shown to improve the immune function and reduce infection rates in the elderly, who need more of a wide range of nutrients. The amino acid-like substance carnitine contributes to a healthy heart because it helps transport oxygen to the cells and produces energy. To protect against osteoporosis, nutritionist recommend supplementation with calcium, magnesium and vitamin D because adequate doses of these are not supplied by multivitamins and mineral formulations. The herb ginkgo biloba enhances blood flow, and may therefore improve such age-related conditions as dizziness, impotence and memory loss. What Else Can You Do?
