Gluten is the compound protein found in abundance in wheat, barley and rye and known to contain lectins and phytates. Lectins are those that irritate your gut and phytates on the other hand causes minerals to bind together.
More than 80 percent of us get inflammation in our digestive system caused by gluten. Some even develop resistance to antibodies due to gluten. Inflammation in the digestive tract could cause premature death and oxidation of intestinal cells. This allows leakages in the gut and opens the door for bacteria and other toxins to get into the blood stream. Together they can cause digestive issues for many. Several studies show antibodies against gluten could lead to damage the heart tissue in many and some find a connection between gluten and cancer. The problematic protein in the gluten is known as gliadin and it is similar to a tissue found in thyroid and pancreas. Any antibodies to fight these could lead to autoimmune disease such as type 1 diabetes.
WGA (wheat germ agglutinin) is one other protein found in gluten and it is known to disrupt mucus membrane causing bacterial overgrowth. GERD and ulcers are being influenced by WGA and contribute to irritation in the digestive tract.
