Study: 2 Coffees A Day May Reduce Risk Of Heart Failure

Drinking two cups of coffee a day could lower your risk of heart failure, a new study finds.

But the study, by researchers at Boston's Beth Israel Deaconess Medical Center, also warns that drinking more than five cups of coffee a day can increase your heart risk.

The findings challenge current guidelines, which say that coffee consumption could increase the risk of heart failure.

With the findings, however, Elizabeth Mostoksy, a study author, told our Newscast unit that consumers need to pay attention to serving size.

"If you translate it to what a serving size is in a typical American coffee chain, it's quite easy to have two cups per day," she said. "And, in fact, most people may have more than that."
