<<Disclaimer: Verify this information before applying it to your situation.>> Perhaps this is a question I ought to put to a doctor, but there is one thing I just don't understand about "strict adherence" to the GF diet. We do not purposefully allow the celiac in our family to eat any gluten. We read labels, but we rely a lot on published lists of GF foods. So,l I cannot say I am certain that our celiac is not ingesting any gluten at all. However, she demonstrates no symptoms. I see many postings on this list which indicate that even with very infrequent, minimal gluten ingestion "the damage is being done" to the villi. What I don't understand is this: If the gut can heal after months (in our case) or years of gluten ingestion preceding diagnosis, why doesn't the gut heal after an accidental gluten ingestion? I can understand that if the gut is taking gluten "hits" of more than minimal amounts day after day, there would be a problem, but that is not what I'm talking about here. My question goes more to this kind of scenario: we are gluten free for weeks, then one day I make a casserole that has one teaspoon of a spice that has some cross-contamination in it, and the celiac eats one cup of the casserole. Please, no lectures. I understand the consequences of indiscriminate gluten ingestion. Perhaps what I really don't understand is the process of how the gut heals. Does anyone know of any literature on the subject that a lay person can read and understand?l
