I do not have celiac but had multiple grain allergies. I had an allergy test done and it came back with wheat, coffee, and teff as a high allergy and barley, rye, spelt, polish wheat, oats, buckwheat, amaranth and tapioca as a mild allergy. I just found out a month ago that I had egg, sugar, artificial sweeteners, coffee, chocolate, caffeine and nut allergies...
