(12-06-08) Vitamin E Linked to Lung Cancer

Taking high doses of vitamin E supplements can actually increase the risk of lung cancer.
A study of 77,000 people found consuming 400 milligrams of vitamin E per day increased cancer risk by 28 percent. Smokers were at particular risk.
An expert writing in the American Journal of Respiratory and Critical Care Medicine said that people should get their vitamins from fruit and vegetables rather than supplements.
Vitamin E is known to be an antioxidant that protects cells from molecules called free radicals. But in high doses, it may also act as a pro-oxidant, causing oxidation and damage to cells.
