                                According to the Celiac Disease Foundation, even trace amounts of gluten can trigger a harmful autoimmune response in those with celiac disease, so assuming your ancient grain granola is gluten free is a dangerous misconception. The truth is that while some ancient grains are naturally gluten-free, others are ancient forms of wheat that contain gluten.
