Radishes

These brightly colored vegetables are packed with potassium, folic acid, antioxidants, and sulfur compounds that aid in digestion. Don't forget the leafy green tops, which contain six times the vitamin C and more calcium than the roots. Thinly slice and toss in a fresh green salad or julienne for coleslaw.
