Gluten is one of the most complex proteins consumed by man. It is a very large molecule relative to other food molecules and for that reason is difficult for the human digestive system to break down. Problems begin when it reaches the small intestine. In sensitive individuals Gluten actually tears holes in the lining of the gut, creating Leaky Gut Syndrome. This allows foreign particles (whatever is in the gut, including bacteria) into the bloodstream. Of course that sets the body's immune system on 'high alert' - resulting in your symptoms.
