Antioxidants
Free radicals are exceedingly difficult substances to conceptualize. They are tiny
reactive molecules most commonly associated within oxygen in biologic systems; hence
the term reactive oxygen species. Free radicals are generated during normal
metabolism - mitochondria produce free radicals as part of their normal process of ATP
synthesis. Humans have two main mechanisms for reducing free radicals - we have
built-in anti-oxidant enzymes that are nutrient-dependent, and we are supposed to
derive anti-oxidants from food, particularly vegetables and fruits. In addition to vitamins
C, E, and beta-carotene, vegetation contains 100s of different types of anti-oxidant
bioflavonoids. The best way to reduce free radical proliferation is to eat fewer calories
and take certain antioxidant supplements.
