Daily supplementation with vitamin E may reduce the risk of chronic obstructive pulmonary disease (COPD) by about 10 per cent in women over 45.
The potential beneficial effects were observed in both smokers and non-smokers.
COPD can cause coughing taht produces large amounts of mucus (a slimy
substance), wheezing, shortness of breath, chest tightness, and other
sympthoms, with cigarette somiking the leading cause.
According to the US National Institutes of Health, COPD is a major cause
of disability, and it is the fourth leading cause of death in the US,
with over 12 million people currently diagnosed with the disease.
The oxidant/antioxidant balance in lung tissue is hypothesized to
contribute to chronic obstructiv pulmonary disease (COPD) risk, said the
researchers, and they noted that observational studies consistently
report high antioxidant status associated with lower risk of COPD and
asthma.
The researchers analyzed data from the WHS, a randomized double-blind
placebo-controlled trial that ended in 2004. Women received either
vitamin E supplements at a dose of 600 IU every other day plus aspirin
at a dose of 100 mg every other day, or placebo.
Over the course of 10 years of study, the researchers documents 760 new
cases of chronic lung disease in the recipients of vitamin E compared
with 846 cases in the recipients of the placebo.
This was equivalente to a 10 per cent decrease in the risk of developing
chronic lung disease, said the researchers, and this was not affected
by the smoking status of the individuals.
