According to the study by Harvard School of Public Health, drinking more than six cups of coffee daily can reduce the risk of getting prostate cancer significantly.

From 48,000 men and 12 years study, researchers discovered that those in this category had a 60% less chance of developing lethal prostate cancer compared with non-drinkers when they drank six cups of coffee every day. Drinking decaf and regular coffee had a similar effect in reducing the chance of getting lethal prostate cancer.

The study reported that the antioxidants and anti-inflammatory compounds inside the coffee influence the body's insulin levels and sex hormone levels. And these two factors are linked with prostate cancer. It is widely known to experts that that insulin plays an important role in the developing of many other cancers as well.

Other studies have revealed that coffee can reduce the risk of Parkinson's disease, type 2 diabetes, gallstones, and liver cancer.

Prostate cancer is the most prevalent form of cancer diagnosed in men living in United States. It is also the second leading cause of death caused by cancer in men and it affects 1 in 6 men. 

The study was published in the Journal of the National Cancer Institute
