What is the effect of traditional salt substitutes in renal diets?

Traditional salt substitutes often contain potassium chloride as the main ingredient. For patients with chronic kidney disease (CKD), managing potassium levels is crucial because the kidneys may not effectively excrete excess potassium, leading to hyperkalemia, a potentially dangerous condition. Since potassium chloride can significantly increase potassium intake, it poses a risk to these patients, making the use of such salt substitutes inappropriate in many renal diets.

In renal nutrition, the focus is on maintaining a balance of electrolytes, and confining potassium intake is vital for ensuring the safety and well-being of individuals with CKD. Therefore, the presence of potassium chloride in many conventional salt substitutes and the subsequent risks associated with them directly supports the correctness of this choice regarding their effects in renal diets.
