Answer

No added salt (NAS) and restriction of salty snacks is recommended. The allowance of salt depends on the presence of edema, hypertension, and administration of sodium-containing medications. Salt intake should be kept to less than 2400 mg/d.

If the child is hypertensive and edematous, further restriction of salt and fluid is emphasized. However, exceptions include diseases in which sodium is lost in the urine (salt-losing nephropathies).

Once these children progress to dialysis or opt for kidney transplantation, a dietician should be consulted again, because the dietary requirements change.
