The belief that dialysis patients require a much higher intake of protein than the average person is widely held among nephrologists and a recent editorial review on the care of patients undergoing hemodialysis advised a protein intake of at least 1.5 g/kg/day in this population. In theory, the requirements for daily protein intake of dialysis patients should be the same as normals plus whatever extra obligatory nitrogen losses are imposed by the dialytic process. Since the average loss of protein and/or amino acids is about 8 g/day in peritoneal dialysis and 8 g per session in hemodialysis patients, the daily intake of protein in dialysis patients needs to be increased only by this small magnitude.
