Kidney Diet Tips

Eating Well on Peritoneal Dialysis (PD)

The dialysis diet is intended to help reduce fluid and waste buildup in your body to help you feel better. But sometimes it can be complicated to keep track of all the limitations. The peritoneal dialysis (PD) diet is less restrictive than a hemodialysis diet, as dialysis treatments are more frequent. (Read Comparing Kidney Diets: Peritoneal Dialysis vs. Hemodialysis to learn more.)

To help incorporate the foods you love into your PD diet, talk with your dietitian and keep the following guidelines in mind.


Your protein needs are higher on PD because some protein is removed during treatments.

  • Include a high-protein food with every meal and snack.
  • Protein-rich foods include meat, poultry, fish and eggs.
  • Plant-based protein sources include lentils and tofu, to name a few. Download the free Plant-based Eating cookbook from


Similar to the hemodialysis diet, phosphorus needs are low.


Your potassium needs may vary on PD. Too much or too little can cause heart and muscle problems.

Quite often, the PD diet is liberal with potassium as potassium is removed through frequent treatments.

  • Potassium is found in fruits, vegetables, dairy products, nuts and seeds.
  • Browse the recipes on for ways to incorporate more fruits and vegetables into your diet. You can also download the free Veggie Lovers cookbook.


Eating too much salt (sodium) may lead to high blood pressure, swelling and difficulty breathing. Both PD and hemodialysis diets limit sodium intake.

  • Salt is found in fast food, convenience foods, canned foods, salty snacks and sauces.
  • Use herb and spices instead of salt to flavor foods. Here are some great recipes from
