Gluten today is not the gluten from our ancient ancestors. It's common sense that we live in a different world and the environment and sciences have changed. Humans have done a lot of "stuff" to this place. The entire food supply, soil, animal grazing (or lack thereof), insects are dying, weather adjustments and science monsters who created GMOs (Monsanto) have altered the entire planet.
