Which Type of Soy Is Richest in Protein?

Soy is a complete protein, containing the whole range of amino acids (the building blocks of protein) necessary for the body to produce protein. The quality of soy protein is rated as high as milk protein and egg, and higher than beef protein. As with all plant foods, soy has no cholesterol. Among the richest sources of soy protein are tofu, edamame and dry roasted soy nuts. Soybeans are often fermented to produce tempeh and miso, two particularly flavorful soy choices. Soy nuts are also transformed into “soy dairy” products including milk, yogurt and cheese.
