hey meg -
i don't believe in lines when it comes to health issues - actually, i'm not good with rules or lines in most areas of my life
i prefer to call it gluten issue spectrum - allergy, sensitivity, intolerance, or somewhere in between - testing doesn't always give the answers you seek because it tries to follow a certain set of rules - i think the best and most effective way is an elimination protocol - not always easy, but imo, way more beneficial -
the only rule that i have is strict adherence - don't even bother if you can't do it 100% !
try giving up all grains and products with any amount of gluten for a week - if you see a difference, then you're on your way to getting better - if no change, then go another week - if after 2 weeks you still see no change whatsoever, then it's likely you have no problem - then it's on to another suspect -
