Can IgG Unverträglichkeitstest help with Darmgesundheit?

IgG food intolerance tests are often marketed as a tool to improve gut health, but the scientific evidence is weak. IgG antibodies indicate immune exposure to foods, which can occur in healthy individuals without any intolerance or gut issue. They are not validated as markers for gut health or intestinal inflammation. Clinical studies have not shown consistent benefits of IgG-guided elimination diets for gut symptoms or microbiome composition. These tests are not diagnostic and should not replace medical evaluation (e.g., by a gastroenterologist). Gut health is complex, involving diet, microbiome, stress, and medications. Relying solely on an IgG test may lead to unnecessary dietary restrictions without real improvement. For persistent digestive issues, a doctor’s assessment is essential. Evidence: marketing – most claims come from commercial labs, not robust peer-reviewed research.
