soy protein benefits
Soy Protein: When, Where, Why, and How-The soybean was introduced to the US in the 1880s, and before then was, and still is, a staple of the Asian diet.
Soy is comprised of 30 % carbohydrate (15 % of this is fibre), 38 % protein, 18 % oil (85 % of this unsaturated), and 14 % moisture. Soy contains all nine essential amino-acids, in the perfect ratio for health and well-being.
Used together in an exercise whey, regimen and soy proteins complement each other well. Whey protein, as mentioned, is high in branched chain amino acids, used as an important energy source by the body during exercise, while soy protein has high amounts of the amino acids arginine and glutamine.
Soy’s other nutritional functions include providing a respectable amount of potassium, zinc, iron, vitamin-E, phosphorous as well as the full B-complex.
