Vitamin E & Heart disease
Preliminary research has led to a widely held belief that vitamin E may help prevent or delay coronary heart disease . Researchers have reported that oxidative changes to LDL-cholesterol (sometimes called "bad" cholesterol) promote blockages (atherosclerosis) in coronary arteries that may lead to heart attacks. Vitamin E may help prevent or delay coronary heart disease by limiting the oxidation of LDL-cholesterol . Vitamin E also may help prevent the formation of blood clots, which could lead to a heart attack.
Vitamin E and cancer
Antioxidants such as vitamin E are believed to help protect cell membranes against the damaging effects of free radicals, which may contribute to the development of chronic diseases such as cancer . Vitamin E also may block the formation of nitrosamines, which are carcinogens formed in the stomach from nitrites consumed in the diet. It also may protect against the development of cancers by enhancing immune function .
Some evidence associates higher intake of vitamin E with a decreased incidence of prostate cancer and breast cancer .
A study of women in Iowa provides evidence that an increased dietary intake of vitamin E may decrease the risk of colon cancer, especially in women under 65 years of age .
The American Cancer society recently released the results of a long-term study that evaluated the effect of regular use of vitamin C and vitamin E supplements on bladder cancer mortality in almost 1,000,000 adults in the U.S. The study, conducted between the years 1982 to 1998, found that subjects who regularly consumed a vitamin E supplement for longer than 10 years had a reduced risk of death from bladder cancer.
Vitamin E and cataracts
Cataracts are abnormal growths in the lens of the eye. These growths cloud vision. They also increase the risk of disability and blindness in aging adults. Antioxidants are being studied to determine whether they can help prevent or delay cataract growth. Observational studies have found that lens clarity, which is used to diagnose cataracts, was better in regular users of vitamin E supplements and in persons with higher blood levels of vitamin E
