NEW YORK - A large study suggests vitamin E may help prevent death from cancer and heart disease in middle-aged men who smoke, contradicting the findings of some previous studies on the subject.
In a study of 29,092 Finnish men in their 50s and 60s who were smokers, those with the highest concentrations of vitamin E in their blood at the study’s outset were the least likely to die during the follow-up period, which lasted up to 19 years, Dr. Margaret E. Wright of the National Cancer Institute in Bethesda, Md. and colleagues report.
There are a number of mechanisms by which vitamin E, also known as alpha tocopherol, might promote health, Wright and her team note in the current issue of the American Journal of Clinical Nutrition. For example, vitamin E is a powerful antioxidant, while it also boosts immune system function and prevents tumor blood vessel growth.
