More good news for coffee lovers: two 8-ounce cups of coffee per day may decrease the risk of heart failure by as much as 11 percent, compared to people who do not drink any coffee. 

According to analysis published in the journal Circulation: Heart Failure,  heart problems  share risk factors with several other cardiovascular disease including high blood pressure and type 2 diabetes.  The study, based on the coffee drinking habits of 140,220 patients, found that those who drank coffee had a lower risk of type 2 diabetes in particular.

But the findings also noted a decrease in protection with excessive coffee consumption.  Specifically, those who drank more than four cups of coffee per day did not see the same protective effects.
