[Nutrition in kidney diseases].

Three dietary measures are useful for chronic progressive renal failure. In a hypertensive patient, salt restriction is a prerequisite for antihypertensive therapy. Protein restriction to 0.6 g/kg of body weight per day can slow down progression of renal disease with the exception of polycystic disease of the adult type. Ketosteril can be given for prevention of essential amino acid deficiency. A normalization of serum phosphorus is essential for slowing progression of disease as well as bone metabolism. Therefore, a diet reduced in phosphates, supported by phosphate binders is prescribed.
