The recommended diet for chronic kidney disease usually suggests reducing a patient's sodium, potassium and protein intake, states the Mayo Clinic. However, dietitians customize patients' diets depending on the condition of their kidneys, overall health and other considerations.
For patients who don't need dialysis, many dietitians recommend a low protein diet that limits daily protein consumption to 1 gram of protein per kilogram of body weight, notes MedlinePlus. Patients who start dialysis need to increase their protein levels. A dietitian may recommend eating a high protein diet, which includes 8 to 10 ounces of high protein foods to minimize the loss of muscle mass. Anemia is also common during the advanced stages of kidney disease, so a dietitian may recommend iron pills or other dietary changes.
A chronic kidney disease diet may limit dairy consumption. Poor kidney function can cause elevated phosphorous levels, which can lead to low calcium levels, reports MedlinePlus. Despite their high levels of calcium, some dairy products, including milk, yogurt and cheese, are high in phosphorous and therefore restricted.
Patients may also need to limit their consumption of oranges, dried fruit, bananas, potatoes, tomatoes and other foods high in potassium. Fruits and vegetables with low potassium, like apples, cherries and broccoli, are better choices, according to MedlinePlus.
People with advanced chronic kidney disease should limit their fluid intake, especially if they are on dialysis. Avoiding foods that have a high liquid content, such as grapes, celery and melons, is also important, states MedlinePlus.
