More is better when it comes to drinking coffee to ward off the risk of deadly prostate cancer, according to a major US study released Tuesday by researchers at the Harvard School of Public Health.
Men who drank six or more cups per day had a 60 percent lower risk of developing the most lethal type of prostate cancer and a 20 percent lower risk of forming any type of prostate cancer compared to men who did not drink coffee, it said.
Even just one to three cups per day was linked to a 30 percent lower risk of developing lethal prostate cancer.
"Few studies have specifically studied the association of coffee intake and the risk of lethal prostate cancer, the form of the disease that is the most critical to prevent," said Harvard associate professor and senior author Lorelei Mucci.
"Our study is the largest to date to examine whether coffee could lower the risk of lethal prostate cancer," she said.
The effects were the same whether the coffee was caffeinated or decaffeinated, leading researchers to believe the lower risk could be linked to the antioxidant and anti-inflammatory benefits of coffee.
