What are the potential benefits and harms of using potassium-containing salt substitutes in CKD patients?
Clinical trials of potassium-containing salt substitutes systematically exclude patients with CKD, so benefits and harms of potassium-containing salt substitutes in CKD are not available. Potassium-containing salt substitutes differ from foods rich in potassium, as such foods may have other health benefits, thus extrapolating data from potassium intake in the diet may not be informative to potassium-containing salt substitutes.
