A good diet for someone with kidney failure is one that limits foods that are high in protein, phosphorus, sodium and potassium as well as the daily amount of fluid intake to avoid fluid retention. Such a diet decreases waste produced by the body, leading to the kidneys functioning better, states the National Institutes of Health's MedlinePlus.
A typical diet for someone with kidney failure includes some fats and carbohydrates, such as bread or cream of wheat, as well as vegetables like green beans, cucumbers, raw carrots, apples, pears and cranberries, according to Drugs.com. However, the diet must be low in protein, sodium and the different minerals cited above overall.
This special diet is necessary for either kidney failure or chronic kidney disease. Kidney failure occurs when the kidneys do not function properly and patients need either dialysis or a kidney transplant, notes the American Kidney Fund.
