Can Coffee and Exercise Help Prevent Prostate Cancer Mortality?
According to two recent studies conducted by researchers from the Harvard School of Public Health, men with prostate cancer may want to consider drinking an extra cup of coffee and increasing their exercise.
The findings of the two studies were presented on December 7, 2009 at the American Association for Cancer Research Conference in Houston.
The first study looked at coffee intake and prostate cancer risk. It began in 1986 and included nearly 50,000 men. Over a 20 year follow-up from 1986-2006, nearly 5,000 cases of prostate cancer were diagnosed.
The researchers found that drinking six or more cups of coffee a day was related to a 19% decrease in overall cancer risk and a 41% decrease in the aggressive form of prostate cancer.
The caffeine in coffee had nothing to do with the results because decaffeinated coffee was just as effective.
Instead, the researchers think it has to do with insulin and glucose metabolism. They cited previous studies that have linked coffee to reductions in diabetes risk.
The second study looked at exercise, and builds on an already large amount of scientific evidence linking exercise with prostate cancer prevention.
The exercise study ran from 1986-2008 and included 2,686 participants with prostate cancer. The researchers found that men who exercised for just half an hour per week had a 35% lower risk of death from any cause and a 22% reduction in risk of death from prostate cancer.
Furthermore, the researchers found that men who participated 5 or more hours of vigorous activity per week had a 56% reduction in prostate-specific mortality.
Over half a million men are diagnosed with prostate cancer every year and over 200,000 deaths result from the disease yearly.
Eating a low fat diet, consuming more foods high in antioxidants (especially green tea) and consuming more omega-3 fatty acids are other great ways to lower your prostate cancer risk.
