[Chronic renal failure: what diet?].
A low protein diet has been traditionally advocated in patients with chronic renal failure (CRF), in order to slow its progression. However, CRF is often associated with malnutrition, aggravating its prognosis, especially in elderly patients. In severe CRF, the spontaneous reduction of appetite coupled with additional restrictions regarding sodium, potassium and phophates may further impact on nutrition status. The potential benefit of a low protein diet is therefore questionable. We only recommend a moderately restricted protein diet (0,8 g/kg/day) in selected patients with no sign of malnutrition. This strategy, if applied, must be supported by a multidisciplinary approach involving a nephrologist and a specialised dietician. Additional dietary restrictions are not justified, except in particular situations.
