4. Bananas
You’ve likely heard the recommendation when a leg or foot muscle cramps up that you should eat a banana. Well, that’s because bananas are a simple snack with loads of potassium which is the arbiter of nerve and muscle function. 1 medium banana offers over 400 mg of potassium, over 10% of your recommended daily value, as well as appreciable amounts of Vitamin C (17%) and dietary fiber (12%). A word to the wise, chomping on a serving of dried banana chips gets you less than half the potassium a fresh banana offers you, and typically contains much more fat from the frying process.
