Drinking coffee (not decaf) may lower your risk of developing skin cancer (non melanoma). Actually the more caffeinated coffee you drink a day the lower your risk. Obviously the ingredient that we are talking about is caffeine. Both in coffee and tea. Caffeine kills precancerous and ultraviolet-damaged skin cells by blocking a protein that they need to divide and multiply.
Ladies, not a reason to start drinking coffee but if you do what great news!
