Abstract: Oxygen radicals and other types of reactive oxygen molecules can be shown experimentally to disrupt many functions in living cells. The best characterized mechanism is DNA damage caused by reactive oxygen species from endogenous sources. Antioxidant defenses normally protect against such damage, and reduced levels of antitoxidants are associated with incresed cancer risk. The importance of supplemental antioxidant vitimins and minerals depends on the individual diet and other lifestyle factors.
