Low-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 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 confusion, irregular heartbeats , or a heart attack .
