Soy Protein is derived from soybeans by water extraction, followed by precipitation, washing, and drying procedures to produce either a soy concentrate (70% protein) or soy isolate (90% protein). Soy protein provides all the essential amino acids needed to fulfill human nutritional requirements for growth, maintenance and physical stress. Soy protein isolate contains high concentrations of naturally occurring isoflavones. Isoflavones are components of soy that have been shown to demonstrate cholesterol lowering properties. According to the FDA, taking 4 servings daily of 6.25 grams of soy protein may reduce cholesterol and the risk of heart disease. It has a lower biological value (BV) than whey, casein and egg proteins. Soy protein is an excellent choice for vegetarians or for those who are lactose intolerant.
