Vitamin E keeps lungs healthy

Doctors use a general term, chronic obstructive pulmonary disease (COPD), to describe conditions that persistently obstruct airways, such as emphysema and bronchitis.

In one study, 39,876 women, aged at least 45, took 600 IU of vitamin E (which is equivalent to about 896 IU) or a placebo. After 10 years of follow up, compared to placebo, women who had taken vitamin E were 10 percent less likely to develop COPD. Researchers believe that, as lung disease develops, damage occurs to sensitive tissues through inflammation and free radical activity and that vitamin E may protect the lung against such damage.
