Antioxidants block dangerous oxidation

One way to protect healthy tissue from the ravages of oxidation caused by active oxygen is to provide free electrons to active oxygen radicals, thus neutralizing their high oxidation potential and preventing them from reacting with healthy tissue.

Research on the link between diet and cancer is far from complete, but some evidence indicates that what we eat may affect our susceptibility to cancer. Some foods seem to help defend against cancer, others appear to promote it.

Much of the damage caused by carcinogenic substances in food may come about because of an oxidation reaction in the cell. In this process, an oddball oxygen molecule may damage the genetic code of the cell. Some researchers believe that substances that prevent oxidation -- called ANTIOXIDANTS -- can block the damage. This leads naturally to the theory that the intake of natural antioxidants could be an important aspect of the body's defense against cancer. Substances that some believe inhibit cancer include vitamin C, vitamin E, beta-carotene, selenium, and gluthione (an amino acid). These substances are reducing agents. They supply electrons to free radicals and block the interaction of the free radical with normal tissue.
