Bananas are the richest natural source of potassium, which helps reduce blood pressure, a major factor for strokes. So eat two bananas a day. Have one for breakfast and one as a mid-afternoon snack. This way if you are someone who doesn’t usually have breakfast you’ll find out how easy it is to do so. The mid-afternoon snack banana will help you overcome that end-of-the-day sluggish feeling. And you’ll be helping to keep your blood pressure healthy without any effort.
