What do studies say about Gluten Training?

The concept of 'gluten training' – deliberately and gradually introducing gluten to build tolerance – is occasionally discussed in lay circles but lacks scientific support. Studies on oral tolerance induction exist mainly for food allergies (e.g., peanut), not for gluten. In celiac disease, gluten training is dangerous and can cause intestinal damage. For non-celiac gluten sensitivity (NCGS), no controlled trials show benefit. Evidence is therefore 'unclear'. Consumers should not rely on such approaches; if gluten-related issues are suspected, proper medical diagnosis is essential.
