Peanut Butter

Two tablespoons land on the National Kidney Foundation higher list for both potassium and phosphorus — portion is everything.

Frequently asked questions

Because it is concentrated: grinding packs many peanuts into two spoonfuls. Healthy for the general public and high in kidney-relevant minerals are both true at once.
These pages are general education about eating with kidney disease, dialysis or a kidney transplant. They are not medical advice and do not replace your own care plan. Kidney diets are individual: what is right for you depends on your stage, your blood tests, your medicines and your other conditions. Always talk to your care team or renal dietitian before changing what you eat, and never stop or change a medicine because of something you read here.
