I'm in the US and have experienced gluten problems.
It's nowhere near as bad as it was, I can eat wheat with no problem, but can't eat a lot for a long time.
But, imported Italian pasta doesn't give me a problem.
I've noticed even now with US wheat I can get constipated, but not with the Italian pasta.
I've heard so many things, like US wheat has 4x the gluten, or is sprayed with RoundUp after harvesting to dry it out, so who knows, but there does seem to be something different.
