Wheat has a specific protein called gliadin. When this protein is digested in the intestines, it releases exorphin, an opioid peptide. These peptides then bond with opiate receptors in the brain creating an addiction to wheat. It is an appetite stimulant and increases the amount of wheat you eat. Wheat also has a highly digestible carbohydrate unique to wheat in the form of amylopectin A. This carbohydrate increases the blood. The increase in blood sugar due to wheat causes the pancreas to release additional insulin; this insulin pushes the sugar into the cells, thus increasing abdominal fat dramatically. After 90 to 120 minutes, the glucose/insulin levels drop quickly and create immediate hunger.
