Paraphrased from "Chemistry for Changing Times" 12th ed, Hill et al,
Prentice Hall 2010:
Antioxidants inhibit spoilage of food in the presence of oxygen.
They minimize fats and oils turning rancid.
They minimize the destruction of some amino acids and vitamins.
Aging is caused in part by the formation of free radicals. *It* *is*
*thought* that antioxidants *may* retard chemical breakdown in cells.
(end paraphrase)
Vitamins C and E are antioxidants, the others are not. An excess of
vitamin C doesn't appear to be harmful to most people. You just pee
out the excess. However, to the best of my knowledge, no decent
double-blind study shows that megadoses of vitamin C do any good.
Interestingly enough, one proper study involved feeding relatively
large amounts of BHT (a CHEMICAL!!!***) to rats daily. Life spans
were increased by a human equivalent of 20 years. Hmmmm.
An excess of vitamin E can be harmful. Current recommendation is to
get the amount of E you need from foods, and minimize or avoid vitamin
E supplements.
