Washington: Two forms of vitamin E – gamma and delta-tocopherols – found in soybean, canola and corn oils as well as nuts do prevent colon, lung, breast and prostate cancers, according to a new study.The question of whether vitamin E prevents or promotes cancer has been widely debated in scientific journals and in the news media.“There are studies suggesting that vitamin E actually increases the risk of cancer and decreases bone density,” said Chung S. Yang, director of the Center for Cancer Prevention Research, at Rutgers Ernest Mario School of Pharmacy and the Cancer Institute of New Jersey.“Our message is that the vitamin E form of gamma-tocopherols, the most abundant form of vitamin E in the American diet, and delta-tocopherols, also found in vegetable oils, are beneficial in preventing cancers while the form of vitamin E, alpha- tocopherol, the most commonly used in vitamin E supplements, has no such benefit.”Yang and colleagues, Nanjoo Suh and Ah-Ng Tony Kong discussed animal studies done at Rutgers as well as human epidemiological studies that have examined the connection between vitamin E and cancer.Yang said Rutgers scientists conducting animal studies for colon, lung, breast and prostate cancer found that the forms of vitamin E in vegetable oils, gamma and delta-tocopherols, prevent cancer formation and growth in animal models.
