High-Potassium Diet

What Is Potassium?

Potassium is a mineral found in many foods, such as whole grains, fruits, veggies, milk, dried beans, and peas. It helps keep your blood pressure normal and also helps muscles like the heart contract the right way.

Why Should I Follow This Diet?

This diet may help lower high blood pressure, especially in people who are also on a low-sodium diet. This can help lower the risk of stroke and other problems from high blood pressure. People with kidney problems should not follow this diet. Talk to your doctor before you make any changes.
