Revealing studies confirm that low levels of dietary intake of potassium, magnesium, and calcium are associated with high blood pressure. When your intake of potassium is low, bringing the level up to normal may lower your blood pressure.Taking extra potassium supplements is not usually necessary unless you take a medication that causes low potassium. Many foods such as cantaloupe, orange juice, bananas and potatoes contain natural potassium and can be added to your daily diet. But watch out! Don't increase your potassium unless you check with your doctor to be sure it is safe for you. Higher than normal levels of potassium in the blood can be dangerous.
Increases in calcium intake in some people may lower their blood pressure.It is a good idea to be sure you take the recommended daily allowance for calcium which is about 1000-1200 mg for adults. But don't increase your calcium intake to higher levels than recommended without your doctor's advice. Some natural dietary ways to increase calcium include adding low-fat milk, yogurt, low-fat cheese, baked beans, sardines with bones, salmon, greens, broccoli, calcium-fortified foods and drinks, and watercress.
