Wheat Germ Agglutinin (WGA) is a powerful lectin in wheat and is not to be confused with gluten, or any other similar wheat protein (there are an immense number of proteins in wheat, due to the fact it is hexaploid, containing 3 pairs of chromosomes, with over 23,000 known proteins already cataloged). It is unique and is part sugar/part protein, which is why it is classified as a glycoprotein. WGA has been demonstrated to bind to the insulin receptors in our body, both activating the insulin pathway and signaling the cell to store energy as adipose (fat) tissue AND blocking the action of insulin by blocking its binding site, resulting in insulin resistance and a resultant elevation in blood sugar (type 2).
