Lay opinion vs evidence: Gluten Training

The concept of 'gluten training' – deliberately and gradually increasing gluten intake to build tolerance – is a lay opinion not supported by robust evidence. Gluten-related disorders include celiac disease (autoimmune), wheat allergy (IgE-mediated), and non-celiac gluten sensitivity (NCGS). For celiac disease, strict lifelong gluten avoidance is the only proven therapy; any 'training' risks intestinal damage and long-term complications. For NCGS, symptoms are subjective and often overlap with irritable bowel syndrome; no validated desensitization protocol exists. While oral immunotherapy exists for some food allergies (e.g., peanuts), gluten is not a standard target due to its unique immunogenicity. Claims that microbiome modulation or gradual exposure can 'train' the immune system to tolerate gluten are speculative. Without proper medical diagnosis (celiac serology, endoscopy), self-experimentation is potentially harmful. Evidence: unclear – no high-quality trials support gluten training. Consumer DNA or microbiome tests cannot guide such interventions.
