Is soy sauce a good source for soy protein?
Although soy sauce is a product of the soybean (fermented soy) and tends to liven up many of our favorite dishes, it contains only 1 to 2 grams of soy protein per tablespoon and is high in sodium. If it’s soy protein you’re looking for, good sources include soy burgers, soymilk, and isolated soy protein powders.
