Common mistakes around Gluten Training

Common mistakes around 'Gluten Training' (attempts to train gluten tolerance) include over-reliance on IgG food tests and confusion between celiac disease and non-celiac gluten sensitivity (NCGS). The KombiCheck allergy+intolerance test measures validated IgE for immediate-type allergies but combines it with unvalidated IgG antibodies against foods. IgG to gluten is a normal immune response to dietary exposure and does not indicate intolerance. Acting on such IgG results can lead to unnecessary dietary restrictions, nutrient deficiencies, and misdiagnosis. Another mistake: starting a gluten-free diet before ruling out celiac disease – this invalidates serology and biopsy. There is no evidence that gradual gluten exposure 'trains' tolerance in celiac disease; strict lifelong avoidance is required. For NCGS, no validated biomarkers exist; diagnosis relies on exclusion and controlled challenge. Evidence is mixed: celiac diagnostics are strong, IgG testing is not. Consumers should use certified labs and seek medical guidance.
