Is coffee actually good for you?

Scientists found genetic evidence that higher blood caffeine levels reduce body weight and diabetes risk. What does it mean for coffee addicts?

High levels of caffeine in your blood may help lower your amount of body fat and even your risk of type 2 diabetes, according to new research.

However, the study does not recommend any particular amount of coffee a person should drink to stay healthy - and more is not necessarily better, as the fat or sugar contained in caffeinated drinks might offset the benefits.

Previous research has suggested that drinking three to five cups of coffee - containing an average of 70-150 mg of caffeine - each day was associated with a lower risk of type 2 diabetes and cardiovascular disease.
