Soporte nutricional en la insuficiencia renal crónica

In predialysis, low-protein diets can be recommended (grade A evidence), since they delay renal progression and reduce mortality. Likewise, the use of oral supplements and specific enteral nutrition formulas can be recommended. In patients undergoing substitutive treatment, there is insufficient evidence to establish recommendations on dietary protein content, the use of oral supplements or specific enteral nutrition products. Dialysis solutions with amino acids and IDPN cannot be systematically recommended. Further studies providing evidence of the effectiveness of nutritional support in CRS in the long term are required.
