"Slice it up and add it to cereal or oatmeal," Giovinazzo suggests. "It will add natural sweetness, so you may not need additional sugar."

Thanks to a healthy dose of potassium, an electrolyte that helps lower blood pressure naturally, bananas are a particularly good choice for people with hypertension.
