Potassium Content of Foods

En Español (Spanish Version)

What Is Potassium?

HCA image for avocado articlePotassium 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 Low-potassium Diet?

Your doctor may recommend following a low-potassium diet if you have kidney problems or are taking certain medications. If you have kidney problems, excess potassium can build up to dangerous levels in your blood. This can lead to muscle weakness or irregular heartbeats.

Why Follow a High-potassium Diet?

When combined with a low-sodium diet, a diet high in potassium can help lower high blood pressure. This can help lower the risk of stroke and other complications of high blood pressure. However, anyone with kidney problems should not follow a high-potassium diet without first checking with their doctor.
