US Pharm. 2011;36(6):8.Boston, MA—According to the Health Professionals Follow-Up Study from researchers at the Harvard School of Public Health, men who regularly drink coffee appear to have a lower risk of developing metastatic or lethal prostate cancer. Men who consumed six or more cups daily had about a 20% lower risk of developing any form of prostate cancer and a 60% lower risk of developing lethal prostate cancer. The reduction in risk was seen whether the men drank regular or decaffeinated coffee and does not appear to be due to caffeine. Coffee contains many beneficial compounds that act as antioxidants, regulate insulin, and reduce inflammation, all of which may influence prostate cancer. In previous studies, coffee consumption has been associated with a lower risk of Parkinson’s disease, type 2 diabetes, and liver cancer.
