Vit. E & cancer prevention - more studies needed
Health Letter, report the health benefits and the safety of vitamin
Numerous university health publications, including the Harvard Health Letter, report the health benefits and the safety of vitamin E. The Harvard publication recently reviewed developments on Vitamin E and reported: "Having vitamin E in your blood is like having a cop on the beat. It is an antioxidant, rounding up the by-products of normal metabolism called 'free radicals,' reactive molecules that damage DNA and cell membranes and encourage plaque build-up in the arteries. "Several large studies that followed participants over several years have suggested that vitamin E supplements protect against heart disease. Because of its antioxidant properties, it has also been promoted as an anticancer agent." According to the Harvard Health Letter, vitamin E "may also help keep your brain healthy," citing a study finding that Vitamin E in supplement form slowed the progression of Alzheimer's disease in people in the middle stages of the condition. The publication noted conflicting studies regarding vitamin E supplementation, however, said that "anticancer findings have been less convincing than the cardiovascular studies." However, recently the National Cancer Institute announced that it will test whether taking vitamin E and the mineral selenium together or separately might "be an effective way to prevent prostate cancer."
