Calcium is also beneficial. Fortunately, potassium and calcium are abundantly present in a large variety of foods. Fruits, vegetables, beans, fish, fowl and lean meats are full of potassium.
Calcium is a little more restricted. Foods rich in calcium usually also contain large amounts of sodium and fat, which can increase blood pressure.
However, moderate amounts of milk are recommended, as well as yogurt, almonds, bananas, grapes, broccoli, potatoes, beans, tofu and sardines.
