Low Potassium Diet

Potassium is a mineral found in many foods. Potassium balance is necessary to help maintain a regular heartbeat and proper muscle function. In certain conditions potassium levels in the body may be too high.

How do I keep my potassium level low?

You can reduce your potassium intake by avoiding or limiting foods high in potassium and by selecting foods with lower potassium content. Most foods contain potassium, so it is also important to control portion sizes.

Use the following guide for meal planning:

____ servings a day of high potassium content foods (250 to 500mg per serving)
