Research has shown that people whose diet is rich in potassium (vegetarians for example) are less likely than others to develop high blood pressure.
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.
Such fruits include: apples, avocado, bananas, grapes, guava, pineapple, watermelon, pears, mangoes, oranges, and papaya.
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.
