Consuming foods that are rich in minerals, such as potassium and sodium, helps replenish electrolytes, says About.com. Electrolytes are found in ions of potassium and sodium as well as calcium, magnesium and chloride.
Eating a balanced diet of fresh fruits, vegetables, legumes and nuts assists in maintaining electrolyte balance. Many of these foods contain natural sources of potassium, sodium and chloride, states About.com. A half ounce of salted peanuts contains the same amount of sodium as most 8-ounce sports drinks as well as 90 milligrams of potassium. The average sports drink contains only 30 milligrams of potassium per 8 ounces. A cup of tea more than doubles that with 88 milligrams of potassium.
Other foods that provide ample servings of potassium are yogurt, broccoli, avocados and bananas, says About.com. An individual can also make a custom electrolyte drink at home. Two tablespoons of lemon juice have almost the same amount of potassium as an 8-ounce serving of the typical sports drink. Mixing 2 tablespoons of lemon juice with 8 ounces of non-carbonated water and adding a small pinch of salt and flavoring or sweetener for taste makes a personal sports drink. Recommended sweeteners are Crystal Light Drink Mix and sugar free syrups, such as Da Vinci or Torino.
