Edamame: Nutrition Facts and Health Benefits

Edamame are young, immature soybeans (Glycine max) harvested and eaten while still green, before the beans have hardened into the yellow dried soybeans used to make tofu, soy milk, and miso. The name comes from Japanese, meaning roughly "stem beans," reflecting the traditional way of eating them directly from the pod. Though most strongly associated with Japanese cuisine, edamame are consumed across East Asia and have become widely popular as a snack and ingredient globally, driven in part by their impressive nutritional profile.

Nutritional Value of Edamame

Edamame are one of the most nutritionally complete plant foods available. They provide approximately 121 kcal and 5.2 g of dietary fibre per 100 g of shelled beans. Their most notable characteristic is their protein content — around 11–12 g per 100 g — and uniquely for a plant food, this protein is complete, containing all nine essential amino acids in meaningful quantities. Edamame are a rich source of vitamin K, folate, manganese, phosphorus, thiamine (B1), iron, magnesium, copper, and zinc. They also contain isoflavones — plant oestrogens that have been extensively studied for potential health effects — including genistein and daidzein.

Health Benefits of Edamame

The complete protein profile of edamame makes them one of the most valuable protein sources for plant-based diets. Folate is essential for DNA synthesis and cell division, and is particularly important during pregnancy. Vitamin K supports bone metabolism and normal blood clotting. Iron in edamame supports red blood cell formation, and absorption is enhanced when eaten alongside vitamin C-rich foods. The isoflavones in soy have been studied for effects on bone density, cardiovascular health, and menopausal symptoms, with research suggesting modest benefits. Edamame's fibre and protein content promote satiety.

How to Select and Store Edamame

Fresh edamame pods should be bright green, firm, and slightly fuzzy. Frozen edamame — whether in the pod or shelled — are equally nutritious and widely available, making them the most practical option for most people. Cook directly from frozen. Refrigerate fresh edamame and consume within a few days. Shelled cooked edamame can be refrigerated for up to four days or frozen for several months.

How to Use Edamame

Edamame in the pod is traditionally boiled or steamed in salted water for four to five minutes and eaten by pulling the beans from the pod with the teeth. Shelled edamame can be added to salads, grain bowls, stir-fries, pasta dishes, soups, and dips. Edamame hummus, made by blending shelled beans with lemon, garlic, and olive oil, is a protein-rich alternative to chickpea hummus.
