Common mistakes around IgG Unverträglichkeit Training

Common mistakes around IgG intolerance training: 1) Confusing IgG with IgE – IgG reflects food exposure, not allergy. 2) Assuming positive IgG results mandate elimination – many healthy individuals have IgG to foods they eat. 3) Using tests to diagnose 'leaky gut' without robust evidence. 4) Leading to overly restrictive diets, risking nutrient deficiencies and disordered eating. 5) Lack of test standardization and reproducibility. 6) Overlooking that IgG may have a protective role. Current guidelines do not support routine IgG testing for food intolerance. Evidence-based approach: focus on symptom tracking and medically supervised elimination diets. Evidence: mixed (mechanistic plausibility, marketing, weak observational data).
