Maintain blood pressure
Bananas are famous for their potassium-a mineral that helps control our blood pressure. But while a banana has nine percent of your daily needs, a baked regular potato has twice as much-20 percent-and a sweet one has 12 percent. But watch how you cook them: Cubing potatoes before boiling can reduce potassium by 75 percent. The best way to maintain it? Bake with the skin on.
