Celiac Disease is essentially an auto-immune disorder that is triggered by eating foods containing gluten, which is in wheat, rye and barley products. While there are blood tests to detect the disease, the true confirmation of the diagnosis requires doing a biopsy of several sites in the small bowel. If the villi in the small bowel show damage, the diagnosis is confirmed.
The only treatment for Celiac Disease is to avoid gluten in the diet. While it’s obvious that those with Celiac Disease need to avoid almost all bread products, newly-diagnosed patients are also taught to recognize the “hidden” gluten in many commercially prepared foods. Even restaurant or home-cooked meals that are (presumably) prepared fresh from gluten-free products are considered suspect if they are prepared in a kitchen that also contains gluten products due to the risk of cross-contamination: a cooking utensil could carry gluten molecules from a food containing gluten to an otherwise gluten-free food.
To avoid that risk, many of those with Celiac Disease are extremely cautious about eating in restaurants or kitchens not their own and will often prepare and take their own food when dining with friends or family. This is reasonable, given that the prevailing teaching is that products with “more than 20 parts per million (ppm) of gluten” will cause damage to their small intestine. Is Any Amount of Gluten Safe for Those with Celiac Disease?
