Half a cup of shelled edamame has the same amount of iron as a 4 oz chicken breast, 10% of the RDA. It also has 10% of the RDA of Vitamins C and A, both age-fighting antioxidants. For 120 measly calories, you get 11 grams protein, 13 grams carb, 9 grams fiber and only 2.5 grams of fat. So it is a wonderful whole food way to eat lean.
To cook: Put edamame pods into a steamer for about 3-5 minutes with a touch of salt! Serve.
