Nutritional recommendations in CKD

It is recommended to reduce protein intake in non-dialysis patients to 0.6-0.8 g/kg body weight, where protein should mainly be of high biological value (animal protein and/or legumes).

Besides this classical low-protein diet, a very-low protein diet (0.3 g protein/kg body weight), supplemented with essential amino acids is a safe and effective treatment for motivated and well monitored patients to postpone the need for RRT as long as possible.

To prevent protein-energy wasting (PEW) monitoring by the nephrologist and a trained dietitian is fundamental to ensure the patient is receiving sufficient energy in their diet.

Phosphorus and sodium restrictions are essential for a good dietary management. In case of hyperpotassemia also dietary potassium needs to be watched.

The updated KDOQI guidelines for CKD care are supposed to be published in 2019.
