My daughter is celiac...it is a European ancestry disorder and in Italy they actually test for it at birth. While I think glyphosate can adversely affect it, if you read "Wheat Belly", you will see the argument for the genetic engineering of wheat over many years being a major cause. The issue isn't bleeding in the gut...the issue is that the villa in the small intestine lie flat, due to the allergic reaction to gluten in Barley, Rye, Oats and Wheat. This in turn causes a malabsorption syndrome which is extremely hard to overcome, although digestive enzymes do help. Many celiacs are able to eat the ancient grains such as Einkorn, because they have not been genetically modified. Truly the only way to treat celiac successfully is to not eat any of the grains mentioned.
