Men who drink abnormally large amounts of coffee everday are at lower risk of prostate cancer and much lower risk of lethal prostate cancer, according to a new study by researchers at Harvard University.
Men who consumed six or more cups per day had a lower adjusted relative risk for overall prostate cancer compared with nondrinkers. The association was stronger for lethal prostate cancer. The average level of daily coffee consumption is slightly less than two cups, according to the study.
Kathryn Wilson, a professor of epidemiology at Harvard’s School of Public Health, was the lead author of the study, “Coffee Consumption and Prostate Cancer Risk,” which appears in the most recent issue of the Journal of the National Cancer Institute published by Oxford University Press. Ironically, the potential health benefits associated with heavey coffee consumption appear to be related to non-caffeine components of coffee.
