Coffee actually prevents colon cancer. It's after all, a bean. There are healthful benefits from coffee..One can always drink de-caf and still get the benefits of it. Studies showed that coffee drinkers have a 70% less risk of colon cancer than tea drinkers. My co worker told me the other day that he has colon cancer. I asked him,"Do you drink coffee?" I wanted to see if the study was true..He said "No! I only drink green tea".
