Potassium Content of Foods

HCA image for avocado article 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.

Reasons to 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.

Reasons to 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, you should not follow a high-potassium diet without first checking with your doctor.
