About this food

Understanding this nutrition reference

Soybeans are protein-rich legumes with a firm texture and nutty flavor. They are the basis of many soy foods, including tofu, soy milk, and tempeh, and are also eaten whole after soaking and cooking, or as edamame when young.

Nutritionally, dry soybeans are concentrated in protein, fat, and fiber. Per 100 g they provide about 446 kcal, 36.5 g of protein, 30.2 g of carbohydrates, and 19.9 g of fat, with 9.3 g of dietary fiber, 2 mg of sodium, and 277 mg of calcium.

Cooked soybeans absorb water and become much lower in calories per 100 g than the dry seeds. For accurate tracking, weigh soybeans dry or cooked as prepared, and use the serving sizes below.
