I do not believe this woman's child (in the article) had a severe reaction to anything she ate at MickeyD's. I don't know of anybody that does (though I also don't know all the people in the world). I think she found a hungry lawyer, with a penchant for frivolity. If John Edwards can channel a little dead girl, then anything like this is definitely possible!
As for more answers, my link is to the Celiac Disease Foundation... They actually have facts!
"To my limited knowledge, yes. From personal experience with my daughter, she has no problems eating anything, these days. She did without stuff until around age 5-6, then we slowly introduced her to a variety of foods (all, under the supervision of her pediatrician). According to the specialists, this is lifelong, but not proven so, in our lives."
Just curious, did your pediatrician follow the reintroduction of gluten with antibody tests or a biopsy? Did he ever test for the genetic markers?
We saw a lawyer once who claimed to have outgrown celiac disease. She then went on a head-spinning list of gastro-intestinal maladies that she was taking medication for.
We also have relatives who literally will go to the grave in pain rather than give up that piece of bread.
