What food can be taken by renal failure patients?

Many: These patients can still eat any foods, but they just need to decrease the amount of potassium and phosphorous containing foods. Just as a diabetic can eat any sweets, they need to limit it. Renal failure patients need to limit total fluids, potassium and phosphorous. If on dialysis, protein is usually encouraged, but if pre-dialysis, high protein intake may not be a good idea.
