Can IgG help with Darmgesundheit?

The short answer: No, IgG food sensitivity tests are not a scientifically validated tool for improving gut health. IgG antibodies simply indicate prior exposure to a food protein – a normal immune response, not a sign of intolerance or gut dysfunction. Major allergy and immunology organizations (e.g., EAACI, AAAAI) explicitly advise against using IgG tests for diagnosing food sensitivities or guiding elimination diets. Gut health is better assessed through microbiome analysis, markers of inflammation (calprotectin), intestinal permeability (zonulin), and clinical evaluation. While MyBody-X offers IgG-based food tests, the evidence for their relevance to gut health is weak and largely marketing-driven. For genuine gut health improvement, focus on a fiber-rich diet, fermented foods, stress management, and medical guidance – not IgG results.
