Edamame is a soy product, and according to Authority Nutrition, it must be cooked before it can be eaten safely because raw soy is poisonous.
Edamame is relatively easy to cook. Once cooked, edamame is eaten hot or cold. Many people cook edamame and store it in the refrigerator for a quick, healthy snack. Healthy Eating notes that the pods containing the edamame are not edible and should be discarded before consumption. Fresh edamame is green in color and should not be consumed if it is yellow or brown. Fresh edamame is best used within three days of the purchase date.
