Probably also caused by other aspects of American wheat (many "sensitive" people notice they can eat bread in Europe just fine), such as higher glyphosate content, fortification with nasty stuff like vitamin A, possibly others.
I remember reading something about it on BBC, how over processed American Wheat ( or food in general ) leads to those symptoms and they can eat European products and bread just fine.
