conv: Any time I order food_comma_ I count on the cook and server to make sure it's handled and cooked appropriately. When I go out to a restaurant_comma_ I order gluten free food items.  I have to trust that the cook and server take my request seriously.  If not_comma_ my food could be "gluten free" but cross contaminated with foods that aren't and still make me ill. What kind of illness occurs if food is cross contaminated? I'm so sorry this happens to you. If it's mild_comma_ just stomach pains for a few days.  If I were to say_comma_ eat a bun that was supposed to be gluten free and it was full gluten_comma_ my joints also inflame.  So you see it can affect more than just my stomach! You suffer from it more severely than most people I know_comma_ this can be devastating to people.  Inflammation is the devil.  I'm just glad I found out how to manage it to improve my quality of life.
