Coffee May Cut Prostate Cancer Risk in Half


A recent study conducted in Italy—a country with a strong coffee-drinking culture—suggests that men who drink more than three cups a day have a lower risk for developing prostate cancer than those who don’t drink coffee. Overall, coffee and prostate cancer research has been divided and studies have produced mixed results.

For this study, researchers analyzed data from 6,989 men over the age of 50. As part of the study, the men reported their daily intake of Italian-style coffee. After about 4 years of follow-up, 100 new cases of prostate cancer were diagnosed in the study participants. According to researchers, men who drank at least three cups of coffee every day had a 53 percent lower risk of developing prostate cancer.

To learn more about the effects of coffee on prostate cancer, the researchers then combined extracts of caffeinated and decaffeinated coffee with prostate cancer cells in the laboratory. They discovered caffeinated coffee extract reduces the cancer cells’ ability to grow, divide, and spread—metastasize. Decaffeinated coffee extracts did not produce the same effect.
