Interesting thought Bartfull,
I have had similar thoughts. It does seem like things just don't add up too much of the time. But then I meet some Celiacs that seem totally fine on a just gluten free diet. They aren't careful about anything else, but some of us are much more careful and still having trouble.
It's so confusing! Research is constantly changing, I wonder how much of what we think we know will be totally different in a few years?
Keep hanging in there.
