My endocrinolost relayed a similar story to me. His wife can not tolerate gluten in the US but does fine digesting gluten in Europe.

I believe most of the strains of wheat grown in the US are potentially more harmful to our digestive systems than elsewhere.

I've heard the US stains are genetically modified to be more resistant to pesticides and that this resistance comes with other deleterious effects. This last part, is a questionable claim that I have no support for and remain skeptical of.
