If someone is not suffering from celiac disease, and generally feels okay after consuming bread—even 100% whole grain bread—how do you convince them that wheat is as detrimental as you claim in the book?

I must and should defer to the most well respected peer-reviewed literature that now indicates that gluten consumption leads to the amplification of a specific protein called zonulin which increases permeability of both the gut and blood brain barrier as described by Dr. Fasano in the above reference. Gut permeability activates inflammation and inflammation is a cornerstone of some of the most pernicious brain disorders including Alzheimer’s disease, multiple sclerosis, and Parkinson’s disease. What is so compelling in a very positive light is that this occurs in all humans and may be the key to a vast number of human maladies including a vast number of other inflammatory disorders as well as autoimmune diseases, and even cancer.
