Until recently, physicians often advised patients to cut down on coffee to improve health. Recent research, however, showed that coffee has many health benefits. It contains essential minerals and antioxidants, which promotes metabolic health, and is high in caffeine, which boosts energy levels.
A Harvard University study showed that regular coffee drinkers had a 60 percent lower risk of prostate cancer, particularly the risk of the aggressive form of the disease. The study followed 50,000 men for 20 years. Other studies found no link between coffee drinking and prostate cancer, so we need more research to test the validity of the study.
