In a study led by the Harvard School of Public Health involving almost 48,000 men over a 22 year period it was determined that coffee (decaffeinated or not) significantly protected against lethal prostate cancer. (Men who drank 6 cups per day had a 60% lower chance of developing it while fewer cups per day were associated with a proportionately greater risk.)
Per the article:
"The researchers chose to study coffee because it contains many beneficial compounds that act as antioxidants, reduce inflammation, and regulate insulin, all of which may influence prostate cancer. Coffee has been associated in prior studies with a lower risk of Parkinson's disease, type 2 diabetes, gallstone disease, and liver cancer or cirrhosis."
The findings have been published in the May 17, 2011 edition of the Journal of the National Cancer Institute.
