Well, if we’re talking heart health here, the American Heart Association (AHA) shared updated advice recently. For better heart health, stick to fewer than five cups of coffee a dayThe AHA said in a statement that up to 400mg of caffeine, or five 240ml (eight-ounce) cups of coffee, a day, “is generally safe for most adults and appears to be linked to a lower risk of several cardiovascular conditions, including heart failure, heart disease and stroke in some individuals”. Drinking unsweetened black coffee has been linked to a lower risk of type 2 diabetes, heart disease, stroke, heart failure and some irregular heart rhythms. Caffeine doesn’t seem to be the only factor at play here, either: decaf coffee is still linked to better health outcomes than no coffee at all.
