You must eat a lot of chicken too! You cannot be a vegetarian or a vegan and be a celiac! You would die of hunger. Gotta love Chick-fil-A!!!! Their grilled chicken and fruit salad - yum - eat it at least twice a week!(with fries cooked in peanut oil!)
I had my someone accuse my teen daughter of being anorexic (she is a ballerina) because of her size/weight/delay. All of that was because she was an undiagnosed celiac! We had issues with my son (before I knew anything about celiac) - His gastroeneterologist took one look at my daughter and said we needed to test her. He was right! Undiagnosed celiacs are literally starving themselves to death - even if they eat a full meal!!!
Notice we aren't talking about Celiac in infants (which is probably behind "failure to thrive" syndrome) but that which develops later in life. That's the 2.3% of the population who have the genes but simply develop it later. Minor intestinal surgery will trigger it BTW. That includes colonoscopy!
Just about all the chicks you see having problems with anorexia are blonds with blue eyes and small builds ~ very typical of so many Norwegian Sa'ami. It's not that they are throwing up all the time, it's that they have figured out the way to avoid spending all your time on the pot is to NOT EAT. So they train them to eat. I hope they train them to not eat sandwiches too.
Real quick, when on travel try Bob Evans “fried cornmeal mush” with an egg or sausage, and a fruit dish. Ends up costing about what a breakfast with two kinds of wheat and wheat by-products would cost. Tell them to “slice it thick” because you can’t eat wheat, and most places will give you enough to gag on.
