In their landmark study in 1981, Doll and Peto estimated that 35% of cancer deaths in the United States could be attributed to dietary factors (1). One of the mechanisms they proposed for this association was "deactivation, or prevention of formation, of short-lived intracellular species" by antioxidants in the diet. At that time, the National Cancer Institute had also begun its focus on cancer prevention (2) and had funded large-scale randomized clinical trials to test antioxidant vitamins and minerals in cancer prevention (311). Among the antioxidant vitamins of great interest, both among scientists and the general public, was vitamin E. The results of these vitamin E trials (35,911), however, have generally been disappointing because they have indicated that intake of this vitamin provides little protection against cancer overall in well-nourished populations.
