Up to five daily cups of coffee are safe for the heart, new review says

Coffee is the most popular way of consuming caffeine across the world, and while it has been associated with multiple health benefits, there is an ongoing question surrounding how much is actually safe to drink. Now, the American Heart Association has put a figure on it: consuming up to 400 mg of caffeine per day, around five cups, is generally safe for most adults and it may be linked to better heart health. “The equivalent of up to five cups of caffeinated coffee per day without added sugars or fillers is safe and does not increase cardiovascular risk,” said Gregory M. Marcus, co-author of the paper and professor of medicine at the University of California, San Francisco.
