Know Which Foods Are High in Potassium

Potassium is an important mineral that helps you keep a regular heartbeat as well as proper muscle and nerve function. Having kidney disease can make it harder for your body to maintain a healthy potassium level of 3.5-5.0 mEq/L if you’re living with CKD or 3.5-5.5 mEq/L if you have ESRD. If lab results show that your potassium level is too high, you'll need to limit high potassium foods and concentrate on a low potassium diet. If your potassium is too low, your dietitian may have you add 1-2 servings or more of foods high in potassium to your daily diet. It’s important to understand and manage your potassium level so you can feel your best and be your healthiest.

TALK TO YOUR DIETITIAN

Review your potassium lab results and discuss whether you should ADD or LIMIT high potassium foods.
