Coffee
According to researchers in The Netherlands, people who drank more than two, but no more than four, cups of coffee a day for 13 years had about a 20 percent lower risk of heart disease than people who drank more or less coffee or no coffee at all. Moderation is the key to coffee's heart-health benefits—the caffeine is a stimulant which can cause a temporary increase in blood pressure, and in excess, can lead to irregular heart beat.
