Don’t feel bad about those days you drink a little too much coffee: A 2016 study published in the Journal of Neurology, Neurosurgery, and Psychiatry found drinking a high consumption—we’re talking more than four a day—can help reduce your risk of multiple sclerosis, a disease that causes the immune system to attack the protective covering of the nerves in the brain, spine, and eyes. And not just a little—by 31 percent.
Malignant melanomas are the most dangerous and potentially life-threatening form of skin cancer and one of the most common cancer types in the United States. Studies have found that there is potentially as much as a 20 percent lower risk when a person drinks a minimum of four cups of coffee daily. The type of coffee matters here, as the study showed that decaffeinated coffee was not as effective. Studies on non-melanoma cancer and coffee have shown that people were 17 percent less likely to develop the most common form of skin cancer, basal cell carcinoma, if they drank three or more cups of coffee daily.
