heart disease

A 2015 study of more than 1.2 million people found that folks who drink 3 to 5 cups of black coffee a day have fewer heart problems than those who drink none. People who drink 5 or more cups don’t have any more problems than anyone else.

Two other studies, meta-analyses that collated data from 11 other research articles, found that drinking 2 to 6 cups a day results in a lower risk of stroke disease. One of those meta-studies included data from more than 500,000 participants.
