- Hemodialysis      - Limit how much liquid and water you drink. Fluid can build up in your body between hemodialysis sessions. Also, many foods contain water. The extra fluid in your body can cause swelling and high blood pressure. Extra fluid in your body makes your heart work harder.
                
-      - Limit sodium, or salt. Watch out for sodium in frozen foods and prepared meals. You can also find sodium in canned foods, hot dogs, and fast food. Sodium makes you thirsty, which makes you drink more water and other liquids than you should.    - Read more in the National Kidney Disease Education Program (NKDEP) fact sheet Sodium.    - Limit potassium. Potassium is found in many fruits and vegetables such as potatoes, tomatoes, oranges, and bananas. Too much potassium can make your heart beat unevenly. Hemodialysis does not remove potassium from your body well.    - Read more in the NKDEP fact sheet Potassium.    - Eat protein-rich foods such as meat, fish, and eggs. Hemodialysis removes protein from your body.    - Read more in the NKDEP fact sheet Protein.    - Limit phosphorus. Phosphorus helps your bones, blood vessels, and muscles work.    - However, too much phosphorus can make your bones weak. Limiting phosphorus can be hard. Foods that contain phosphorus, such as meat and milk, also contain protein that you need. You should be careful to eat enough protein, yet not so much that you get too much phosphorus. You can avoid other foods that contain phosphorus, such as cola, tea, beans, and nuts.    - Read more in the NKDEP fact sheet Phosphorus.    - Find healthy ways to add calories to your diet. Calories are found in all foods and give your body energy. Many people on hemodialysis do not have a good appetite and do not get enough calories. Vegetable oils are good sources of calories. Vegetable oils include olive oil, canola oil, and safflower oil. Use them on breads, rice, and noodles. Hard candy, sugar, honey, jam, and jelly provide calories and energy. However, if you have diabetes, speak with your doctor or dietitian before eating extra sweets.    - More information about nutrition for people who are on hemodialysis is provided in the NIDDK health topic, Eat Right to Feel Right on Hemodialysis.    - Peritoneal dialysis      - Drink as much water and other liquids as you need. If you are holding too much fluid or too little fluid, your doctor needs to know.    - Limit sodium to control your thirst and help prevent heart problems. You can use spices other than salt to flavor your food.
