Potassium is a key mineral that many adults get too little of. You need it to build proteins and muscles. It helps control your heart beat. Too little of it can cause you to become weak and tired. Not a fan of the banana? No problem. You can get also get it from potatoes (with the skins), lima beans, tomatoes, and citrus fruits.
Some health problems can be made worse by eating foods high in potassium. These include kidney disease and certain heart conditions. Talk with your doctor first if you have any health problems or are taking any medications.
