All grains, including other non-gluten containing grains like oats and corn, are bad because they contain gut irritating lectins and mineral binding phytates, but you’ll learn here why gluten-containing grains and wheat especially can not only cause the same problems as other grains, but also cause much more trouble down the road.
Three main constituents are of interest here: gluten, WGA (wheat germ agglutinin) and opioid peptides found in wheat. Gluten is a compound protein that composes about 80% of the protein found in wheat, barley and rye and WGA is a lectin found in wheat that can be particularly damaging. Opioid peptides are psychoactive chemicals and those found in wheat are similar to those found in other well known psychoactive drugs like opium or morphine.
Contrary to what is believed by many, wheat is not to be avoided only by those who suffer Celiac disease, the autoimmune disease caused by a reaction of the immune system against gliadin, a gluten protein. Those with Celiac disease only react more strongly to wheat and gluten than those without the disease, but most people have a reaction in some way or another to wheat consumption, often in insidious ways.
