Soybean

What Is Soybean?

Soybean (Glycine max) is the seed of a legume plant native to East Asia, harvested after ripening and drying. It is one of the highest-protein foods among plant-based sources; it is therefore also called a "complete protein" source, because it contains all the essential amino acids the body needs.

Its dried beans can be soaked and boiled for direct consumption, and it is also the raw material for many processed products such as tofu, soy milk, soy sauce, miso, and tempeh.

Nutritional Values of Soybean

100 g of boiled soybean contains approximately 173 kcal, 16.6 g plant-based protein and 9.9 g carbohydrate. It is also a notable source of minerals such as iron, folate, and calcium compared to other legumes.

What Are the Benefits of Soybean?

With its high and balanced protein content, soybean is preferred as part of a balanced diet, especially by those seeking a plant-based protein source. Studies examining the relationship between its isoflavones and hormone balance are ongoing; these findings have not yet turned into a definitive health recommendation.
