Swiss chard is a vegetable that is in the same family as the common beet, however while the root of the beet is commonly eaten, it's the leaves of the Swiss chard that are consumed. Recent nutritional analysis has shown that Swiss chard is second only to spinach on the world's healthiest vegetable list. Packed with anthocyanins and fiber it's one of the most antioxidant rich foods as demonstrated in the vivid colors of the leaves.
