Soy Protein Isolate

Soy protein isolate is a powder that has been separated from the other components of the soybean, making it very high in protein and almost carbohydrate and fat-free.

Soy protein isolate has been around since 1936 when it was first used mainly to make industrial material. It was over 20 years later before it became food-grade and sold in many different products such as breads, breakfast cereals and soups.

Health benefits

Soy protein isolate is considered to be a complete protein as it contains all 9 of the essential amino acids, which our body cannot make and we must consume through the diet.  The digestibility of soy isolate is very high, even when compared to the whole soy bean and to soy flour.

Soy protein contains phytoestrogens, which bind to the oestrogen receptors in the body to help balance the levels of this hormone.  There is a lot of research on phytoestrogens and many studies show promising health benefits including the possible reduced risk of some cancers, osteoporosis and heart disease. Consuming soy protein is also linked to lower blood cholesterol and lower LDL (bad) cholesterol.
