In his book Wheat Belly, William Davis wrote that gluten is a poison that caused a number of diseases, including asthma, arthritis, multiple sclerosis, schizophrenia and many other health issues. This is supported by neurologist David Perlmutter who, in his book Grain Brain: The Surprising Truth About Wheat, Carbs, and Sugar—Your Brain’s Silent Killers, wrote that “[gluten] represents one of the greatest and most under-recognized health threats to humanity.”

Now, one question begs answering: How could gluten, a protein found in grain products which have sustained humanity of thousands of years, suddenly become a culinary and health villain?

There are many theories offered. Some researchers argued that wheat genes have become toxic in that most wheat products available today are a result of genetic research, while our body’s way of processing wheat never evolved. Scientists believe that this is the reason why the number of people with gluten sensitivity and celiac disease is on the rise.
