Red Wine May Lower Lung Cancer Risk

Dr. Chao analyzed data collected through the California Men's Health Study, which linked clinical data from California's health system with self-reported data from 84,170 men aged 45 to 69 years. Researchers gathered demographics and lifestyle data from surveys computed between 2000 and 2003, and identified 210 cases of lung cancer.

Researchers measured the effect of beer, red wine, white wine, and liquor consumption on the risk of lung cancer. Adjustments were made for age, race/ethnicity, education, income, body mass index, history of chronic obstructive pulmonary disease or emphysema, and smoking history.

Among the study participants, there was on average a 2% lower lung cancer risk associated with each glass of red wine consumed per month. The most considerable risk reduction was among smokers who drank one to two glasses of red wine per day. The researchers reported a 60% reduced lung cancer risk in these men. Researchers cautioned men to stop smoking as the best way to reduce lung cancer risk; noting that even men who drank one to two glasses of red wine per day still face higher lung cancer risk than do non-smokers.

No clear associations with lung cancer were noted for consumption of white wine, beer, or liquor. "Red wine is known to contain high levels of antioxidants. There is a compound called resveratrol that is very rich in red wine because it is derived from the grape skin. This compound has shown significant health benefits in preclinical studies,” Dr. Chao said.

Dr. Chao stressed, however, their findings should not be interpreted as recommending heavy alcohol consumption. His study's findings were the reported in the October 2008 issue of the journal Cancer Epidemiology, Biomarkers, and Prevention.
