Eating the right foods can help you feel better while on peritoneal dialysis. Talk with your dialysis centers dietitian to find a meal plan that works for you. Your dietary needs will depend on your treatment and other factors such as your weight and activity level. Staying healthy with CKD requires watching what is in your diet:
                
- Protein is in foods from animals and plants. Protein provides the building blocks that maintain and repair muscles, organs, and other parts of your body. Peritoneal dialysis can remove proteins from your body, so eat high-quality, protein-rich foods such as meat, fish, and eggs. However, many high-protein foods also contain phosphorous, which can weaken your bones. Talk with your dietitian about ways to get the protein you need without getting too much phosphorous.  - Phosphorus is a mineral that helps your bones stay healthy and your blood vessels and muscles work. Phosphorus is a natural part of foods rich in protein, and food producers often add it to many processed foods. Phosphorus can weaken your bones and make your skin itch if you consume too much. Peritoneal dialysis may not remove enough phosphorus from your body, so you will probably need to limit or avoid high-phosphorus foods such as milk and cheese, dried beans, peas, colas, nuts, and peanut butter. You may also need to take a pill called a phosphate binder that keeps phosphorus in your food from entering your bloodstream.  - Fluid includes water and drinks such as fruit juice and milk and water in foods such as fruits, vegetables, ice cream, gelatin, soup, and ice pops. You need water for your body to function properly; however, too much can cause swelling and make your heart work harder. Over time, having too much fluid in your body can cause high blood pressure and congestive heart failure. Peritoneal dialysis might cause you to have either too much or too little fluid, depending on the strength of the solution you use. Your diet can also influence whether you have too much or too little fluid. Your dietitian will help you determine how much liquid you need to consume each day.  - Sodium is a part of salt. Many canned, packaged, frozen, and fast foods contain sodium. Sodium is also a part of many condiments, seasonings, and meats. Too much sodium makes you thirsty, which makes you drink more liquid. Try to eat fresh foods that are naturally low in sodium, and look for products that say low sodium on the label, especially in canned and frozen foods.  - Potassium is a mineral that helps your nerves and muscles work the right way. Peritoneal dialysis can pull too much potassium from your blood, so you may need to eat more high-potassium foods such as bananas, oranges, potatoes, and tomatoes. However, be careful not to eat too much potassium. Your dietitian will help you choose the right amount.  - Calories are units for measuring the energy provided by foods and drinks. Eating foods with too many calories, such as oily and sugary foods, can make you gain weight. Your body can absorb the dextrose from your dialysis solution, which can increase your calorie intake. You may find you need to take in fewer calories to prevent weight gain. Your dietitian can help you create and follow a diet to stay at a healthy weight.  - Supplements help provide some of the vitamins and minerals that may be missing from your diet. Peritoneal dialysis also removes some vitamins from your body. Your doctor may prescribe a vitamin and mineral supplement that scientists have designed specifically for people with CKD and kidney failure. Never take vitamin and mineral supplements that you can buy over the counter. They may be harmful to you. Talk with your doctor before taking any medicine, including vitamin and mineral supplements, that he or she has not prescribed for you.
