But how does coffee affect overall health? Apparently it doesn't affect overall health at all, according to a study in the "American Journal Of Clinical Nutrition".
Researchers looked at over 40,000 German adults over nine years. Those who drank more than four cups of coffee a day had the same health issues as those who did not drink coffee. The conclusion, if you are a person in good health you're at no greater risk of developing a chronic disease than a person who does not drink coffee.
