Antioxidants bind to and neutralize ('scavenge') free radicals, thereby transforming them into non-toxic compounds and blocking their genotoxic and carcinogenic effects.  This class of agents includes the vitamins C and E, the carotenoids, and selenium.  Organic antioxidants are found in high concentrations in fruits, seeds and vegetables. (NCI04)"}]
