You might be accustomed to cutting off and trashing the greens that come on top of your beets, but you really should be eating them, because FitSugar says beet greens are incredibly nutritious. One cup contains no fat and just 39 calories, plus you'll get 220 percent of your daily allowance of vitamin A and 60 percent of your vitamin C.

FitSugar says these greens cook and taste a lot like Swiss chard, and they recommend you blanch them in water for few minutes, drain and then prepare with a little olive oil, salt and garlic.
