A study led by Dr. Chaofu Ke suggests that moderate coffee or tea consumption may lower the risk of cardiometabolic multimorbidity. Drinking three cups daily could reduce this risk by 48.1%, while 200-300 mg of caffeine may lower it by 40.

The caffeine in your coffee or tea might not just be a daily vice — it could be reducing your risk for heart disease, according to new research.

Drinking three cups of coffee a day -- or about 200 to 300 milligrams of caffeine -- lowered the risk of health problems linked to the heart or metabolism, researchers found.
