Protein is needed to provide
the body with amino acids, and is a major component in muscle, hair,
nails, and skin. However, not all proteins are created equal. The soy
protein is known as a complete protein, which means that it contains
all of the essential amino acids. It is also known to contain very
little fat, cholesterol, or lactose. For vegetarians and those who are
lactose intolerant, soy protein is a good option to get a non-animal
protein in the diet. In addition to the usual benefits of a good
protein, soy proteins contain saponins, phytosterols and isoflavones.
These various components have been demonstrated to have a range of
positive health effects, from lowering cholesterol levels to improving
the immune system.
