Better renal outcomes, as well as lower blood pressure and albuminuria levels have been shown in two RCTs and a small observational study among adults, non-dialyzed CKD patients on sodium restricted diets (alone or in combination with other behavioral intervention and protein restriction), compared with those who do not reduce sodium intakes. The prescribed sodium-restricted diets in the RCTs were targeted to sodium levels of 1,150mg to 1,840mg (MDRD study) and 1,955mg (a small RCT) per day. Weak observational data also support dietary protein and salt restriction to stabilize renal function in kidney transplant patients.
