I have celiac disease and a wheat allergy, which presented at the age of 3 comorbidly.

If I ingest gliadin, my immune cells take the gliadin, run a nice little check on it, and then raise holy hell and destroy my gut villae.

If I come into contact with wheat, I get a histamine response. Even a bag of (organic, locally produced) wheat flour opened in the same room as me used to be enough to make my airways close up.
