I recently determined through an elimination diet that I am sensitive to chicken (especially dark meat) and eggs. I started wondering what was in chicken feed and found that many contain wheat, barley and/or rye. So far I haven't found a source that doesn't use a feed like that. I would think that the molecule would be altered in the digestive tract of the chicken. On the other hand, it doesn't get digested in OUR digestive tracts, so maybe? Anyone else have a problem with chicken and eggs? Or has anyone ever heard of this being addressed in research?
