Drinking 5 Cups of Coffee a Day Could Reduce Heart Risk

A new American Heart Association scientific statement indicates that consuming up to 400 milligrams of caffeine, roughly three to five cups of plain coffee daily, is safe for most adults. This habit may be linked to lower risks of cardiovascular disease. However, benefits depend on preparation; coffee and tea are more favorable than energy drinks. Added sugars, creams, or sweeteners may cancel these advantages, as noted by cardiologist Gregory Marcus from the University of California, San Francisco.
