Antioxidants- (Good Guys) Free Radicals (Bad Guys)
Antioxidants are those enzymes, amino acids, supplements, vitamins, and minerals that protect our bodies from free radicals, uncontrolled oxidations that damage cells and weaken the immune system. The body generates free radicals daily simply by burning fuel for energy. They are a necessary but unwanted by-product. Various environmental and physical stress-from air pollution, smoking, drinking alcohol, and disease to charcoal-broiled food, old age, and vigorous exercise-generate extra free radicals.
