A dialysis patient should avoid foods that are high in sodium, potassium and phosphorus, including bananas, cheese, chocolate, ice cream, peanut butter and dried beans, states DaVita. Other foods to avoid include oranges, nectarines, star fruit, potatoes and tomatoes, according to the National Kidney Foundation.
A high-protein diet is recommended for dialysis patients to keep blood protein levels normal and maintain optimal health, notes the National Kidney Foundation. Eating 8 to 10 ounces of protein-rich food each day, such as meat, poultry, fresh pork or eggs, is recommended. A 3-ounce serving of protein is generally the size of a deck of cards. While nuts, seeds, peas and lentils are good sources of protein, dialysis patients should avoid them because they are high in potassium and phosphorus.
Dialysis diets typically do not limit grain, bread and cereal consumption, notes the National Kidney Foundation. Avoiding foods that are labeled whole wheat or high fiber is advised because they have a higher phosphorus content. Because most dairy foods contain high amounts of phosphorus, it is best to limit intake to 1 ounce of cheese or 1/2 cup of milk or yogurt daily. Good fruit and vegetable choices for a dialysis diet include apples, grapes, broccoli, lettuce and peppers.
