I know you asked Shauna this, but I thought I'd put my 2 cents in. I ask all those questions and go to farmer's markets too, but to begin with you can try something simpler and see if you get any improvement.
what is the super super gluten free diet or where can i find it?
Eat only produce and meat. With produce watch out for things grown on straw like strawberries and mushrooms. Watch for things coated like apples and citrus. Wash and peel everything. With meat watch out for chicken, and get meat in the big packages that come directly from the meat processing facility, not cut up in the store. With seafood, don't get farmed, and make sure that they change gloves and get it directly from the package. Avoid soy, dairy, grains, beans, coffee, spices, chocolate and anything processed at all, even salt.
You can try this for a couple of weeks and if it works. Then you are probably a super sensitive celiac. You can start adding things. Add one per week and keep track of your symptoms. You can start asking all those questions at the farmer's markets.
