  • High-Potassium Diet

    What Is Potassium?

    Potassium is a mineral found in many different foods, including whole grains, fruits, vegetables, milk, dried beans, and peas. Potassium helps maintain normal blood pressure and also helps muscles, including the heart, to contract properly.

    Why Follow a High-Potassium Diet?

    When combined with a low-sodium diet, a diet high in potassium may help lower high blood pressure . This can help lower the risk of stroke and other complications of high blood pressure. If you have kidney problems, you should not follow a high-potassium diet. Talk to your doctor before changing your diet.
