10 Low Electrolyte Foods for People with Chronic Kidney Disease

Electrolytes are essential nutrients necessary for maintaining a proper balance of hydration and pH in the body. (1) However, for those diagnosed with chronic kidney disease, limiting some or all electrolytes may be necessary. (2)

Electrolytes for the body include sodium (NA), potassium (K), calcium (CA), magnesium (MG), Phosphorus (P), and Chloride (CL). (1) Sodium and chloride constitute table salt and therefore are widely found in modern diets.

Foods low in electrolytes include refined oils, honey, certain boiled and drained vegetables, low mineral water, certain fruits, and for protein: egg whites. (3) Below are 10 foods low in electrolytes, for more, see the article of low potassium foods, and low phosphorus foods.
