Bananas are great for dehydration cramps.
True, but there’s nothing magical about bananas. The potassium in bananas may be key. Potassium, another electrolyte, helps blunt the effects of sodium and, with help from your kidneys, moves it out of your body. Think of sodium and potassium on opposite sides of a seesaw, working to balance each other to achieve proper hydration. Most people get around half the recommended 4,700 milligrams of potassium daily, says Megan Meyer, of the International Food Information Council Foundation. Imbalance can also affect blood pressure and heart contractions.
