Just like sodium, potassium must stay balanced in your body. If your kidneys are not working well, potassium levels in your blood can rise. High potassium levels affect your heart rhythm, so your diet for managing kidney disease may include a potassium limit. Your doctor or registered dietitian nutritionist will let you know if you need to avoid foods high in potassium, and your RDN can explain how to stay within your limit.

Potassium is found in many fruits and vegetables, beans, nuts and dairy foods.
