10 Foods High in Electrolytes

Electrolytes are essential nutrients necessary for maintaining a proper balance of hydration and pH in the body. (1)

Key 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.

For the purpose of this article, we will list foods high in sodium, potassium, calcium, magnesium, and phosphorus. In order to avoid bias, we will only rank foods without added sodium, with the exception of pickles.

Foods high in electrolytes include milk, yogurt, soymilk, squash, cheese, green leafy vegetables, pickles, coconut water, and celery. (2)
