Sažetak
Free radicals are highly reactive molecules which have been linked to both heart disease and cancer.A number of factors, including alchocol, stress and enviromental pollutans can increase the generation of free radicals, the most toxic being the hydroxyl radicals, the superoxide radical, the singlet oxygen radical, and the hydrogen peroxide radical.No single antioxidant compaund can neutralise them all.Antioxidants are a group of compounds that act as free radicals scavengers, donating electrons and neutralising free radicals, preventing their damage to other cells.They convert free radicals to harmless waste products that get eliminated from body before they can do damage ; some may even repair previous damage.the human body produces its own antioxidants, mostly from vitamins and minerals in the diet.but as you grow older, the cumulative effect of free radicals damage from numerous sources, such as ozone, cigarette smoke, drugs, Xrays, and pesticides, can overwhelm your natural defences.some of the best nutritional antioxidants are vitamins C, E, beta carotene, lipoic acid, coenzyme Q10, proanthocyanidins, seleniumand flavonoids.Each substance has a different job to do, so it is important to have a diet rich in all of them.And, since the long-term effects of taking antioxidant sulements are still unknown and their benefits are still not proven clinically, a healthy diet is the safest, surest way.
