Coffee

Caffeine intake and basal cell skin cancer:

Caffeine may reduce the risk of developing skin cancer, specifically basal cell carcinoma (BCC), according to a study of 112,897 participants (72,921 female nurses and 39,976 male health professionals). When participants were ranked according to caffeine consumption, with the highest consumption at the top and the lowest at the bottom, they found for women, the top 20% of caffeine consumers had an 18% lower risk of BCC than the bottom 20%. For men, the risk was lowered by 13%. The researchers also found that drinking 3 cups of caffeinated coffee was linked to a 21% lower risk of developing BCC in women and a 10% lower risk in men, compared to drinking less than 1 cup per month. And caffeine from other dietary sources (tea, cola, and chocolate) also had a similar effect: the higher the intake, the lower the risk of BCC. (4)
