Is cutting out coffee the best bet for your health? Not necessarily. Sure, if you drink too much, caffeinated coffee can give you the jitters or interfere with sleep. But you can also reap significant perks from coffee, both caffeinated and decaf. Studies show that drinking coffee regularly may reduce your risk of Parkinson’s disease, colon cancer, diabetes, and even headaches. Scientists also believe that coffee may play a role in improving memory and decreasing the risk of Type 2 diabetes. Multiple studies have shown that coffee drinkers are up to 80 percent less likely to develop Parkinson's disease. In other studies, colon cancer was reduced by about 25 percent in individuals who drank at least 2 cups a day. While more research is needed, most health experts now believe that the health benefits of coffee outweigh the negatives.
