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?
Foods High and Low in Potassium
Food With High Potassium
The high-potassium foods on the table contain more than 200 milligrams (mg) of potassium per serving. This is considered to be high in potassium. In general, you should avoid these foods if you need to limit how much potassium you eat. However, you may be able to work with a dietitian to add small portions of your favorite foods.
Food With Low Potassium
The foods in the right-hand column are considered to be low in potassium. Eating these foods can help keep your potassium level normal. Remember, though, that eating more than one serving of any of these foods can make it a high-potassium food.
