In a study conducted last month at Cornell University, daily supplementation of vitamin E was found to reduce the risk of chronic obstructive pulmonary disease (COPD) in women over 45 years of age. Data was analyzed from almost 40,000 women who participated in the Women’s Health Study and it was determined that smokers and non-smokers could reduce their risk of COPD by about 10%.
In the study, appearing in the journal Thorax, women received either 600 IU of vitamin E every other day plus aspirin at a dose of 100 mg every other day, or placebo. Over a period of 10 years, the researchers recorded 760 new cases of COPD in the study participants who took vitamin E compared with 846 cases in the control group.
Chronic obstructive pulmonary disease is a progressive disease that obstructs airflow making it difficult to breath. It can cause shortness of breath, coughing and wheezing. Smoking is the biggest cause of COPD, but long-term contact with other lung irritants, like dust, air pollution, or chemical fumes, may also be contributing factors.
