ReviewLight and shadows of dietary protein restriction in elderly with Chronic Kidney Disease

Approximately 45% of the elderly population suffers from chronic kidney disease (CKD). The onset and the course of CKD can be ameliorated to a significant degree by several interventions, such as lowering blood pressure and serum lipid levels and achieving optimal glucose control in diabetes. In elderly patients with more advanced CKD, additional treatment may be needed. In these patients, a low-protein diet (LPD) regimen may delay the need for dialysis therapy. However, in the elderly, feasibility and compliance to LPD could be difficult and its effects are uncertain. In this contribution, we discuss the usefulness and the barriers of LPD regimen in the elderly.
