I'm on vacation and can't find gluten free food. Does a little gluten (bread, cake) destroy my gluten free diet? If so for how long? I'm back home in 2 weeks and will resume my gluten free diet. What are the consequences of occasional lapses into gluten foods? My TPO (latest 273, was 120) and TG (latest 475, was 500) antibodies results had been increasing which caused me to start a gluten free diet. Am getting blood tested again in 2 weeks.
