Potatoes

While potatoes are low in calories — just 110 in a medium potato — they’re high in nutritional value. One potato provides you with 45% of your daily recommended Vitamin C, 620 mg of potassium and 2g of fiber. Free of sodium, cholesterol and fat, potatoes help you maintain a healthy circulatory and digestive system, boost your energy levels with 26 grams of carbohydrates and are loaded with antioxidants that help you repair damaged tissues and recover from exercise.
