When is Gluten Training actually useful?

The term 'gluten training' is not a medically established concept. It usually refers to the deliberate reintroduction of gluten after a gluten-free diet, often in the context of a gluten challenge for celiac disease diagnosis. This should only be done under medical supervision, as it can trigger severe immune reactions in celiac patients. For individuals without celiac disease or wheat sensitivity, there is no proven need for gluten training. The idea of 'training' the body to tolerate gluten through gradual exposure lacks scientific support. Some commercial programs promote such approaches, but no randomized controlled trials exist. If celiac disease is suspected, a standardized gluten challenge under a doctor's guidance is appropriate. Without a medical indication, gluten training is not recommended and may cause harm. Evidence: practice-based, no robust studies.
