AHA: Coffee Safe, Energy Drinks Risky for Heart

The American Heart Association says most healthy adults can safely drink up to 5 cups of black coffee a day.

This amount might even lower the risk of heart problems.

But energy drinks are different—they have much more caffeine and can be bad for your heart.

Coffee has good stuff in it that helps your blood vessels and reduces swelling.

However, adding lots of sugar or cream can make coffee less healthy.

Some people might feel their heart race or have trouble sleeping after drinking coffee, so it's important to know how your body reacts.

The best way to have coffee is filtered, like with paper filters, because it has less of a substance that can raise bad cholesterol.
