Vitamin E protects against tobacco smoke.

Vitamin E Protects Against Tobacco Smoke

LA GRANGE, ILLINOIS: New evidence suggests that increasing vitamin E intake may help persons exposed to cigarette smoke reduce their susceptibility to lung damage.

That should be good news for smokers, many of whom are at high risk for development of lung cancer or emphysema, and also for passive nonsmokers who breathe the smoke of others' cigarettes.

Cigarette smoke is a source of free radicals, highly reactive particles that have been shown to cause damage to the cells of the lungs. Lung tissue is particularly susceptible to free radical damage because lung structures are very thin and delicate. Free radical damage has been linked directly to the development of lung cancer, emphysema, and chronic bronchitis.

Vitamin E is a natural antioxidant that acts by trapping and neutralizing free radicals whose primary targets are the fatty portion of lung cells.

Because smokers are under a "high and sustained free radical stress" and are considered to be at increased risk for the development of free radical diseases such as heart disease and cancer, a substance such as vitamin E is heralded with enthusiasm, according to Dr. Garry Duthie of the Rowett Research Institute of Aberdeen, Scotland. He recently reported on a study that affirmed the vitamin's efficacy in providing defense against oxidant injury.
