This document summarizes current guidelines and evidence regarding salt restriction for patients with chronic kidney disease (CKD). Several studies have found associations between lower sodium intake and reductions in blood pressure, proteinuria, and slower CKD progression. However, the data are mixed and do not clearly support strict sodium restriction. Larger and longer studies are still needed to better understand the effects of sodium intake on renal and cardiovascular outcomes in CKD patients. Overall, moderate sodium restriction may provide benefits but a strict approach is not strongly supported by current evidence.
