17 Foods High in Electrolytes
Electrolytes are essential nutrients necessary for maintaining a proper balance of hydration and pH in the body. A deficiency or imbalance of any electrolyte can disrupt electrical signaling in the muscles leading to muscle cramps, fatigue, irregular heartbeat, and numbness.
Key electrolytes for the body include sodium (NA), potassium (K), calcium (CA), magnesium (MG), Phosphorus (P), and Chloride (CL). 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. We will rank foods by the total daily value (%DV) they provide for each of these nutrients. In order to avoid bias, we will only rank foods without added sodium, with the exception of pickles.
Foods high in electrolytes include yogurt, milk, cheese, soymilk, seafood, and green leafy vegetables. Below are 17 foods high in electrolytes, for more, see the list of less common foods rich in electrolytes.
