Electrolytes are minerals found in the human body that break down with sweat and urine. Exercise, stress and certain diets cause the body to lose a lot of it, which leads to many imbalances: cramps, general fatigue, as well as a craving to eat a particular food. The deficient body is simply looking for the minerals it has lost. You can find electrolytes in the diet. The richest foods are leafy green vegetables, legumes or whole grains. It may also be beneficial to add supplements to your diet to replenish your electrolytes.olytes.
