What should I know about IgG Unverträglichkeit Ernährung?

IgG food intolerance tests are scientifically controversial. Unlike IgE-mediated allergies (immediate type), elevated IgG levels often reflect normal immune exposure—meaning the body has encountered a food, not necessarily an intolerance. Many commercial providers market IgG tests for digestive issues, fatigue, or skin problems, but the evidence is weak: studies show high false-positive rates and no reliable correlation with symptoms. Medical societies such as the European Academy of Allergy and Clinical Immunology (EAACI) advise against IgG-based elimination diets. A more evidence-based approach for suspected food intolerances involves a symptom diary followed by a controlled elimination and rechallenge diet under medical supervision. MyBody-X tests are not diagnostic; results should not be the sole basis for dietary changes. Caveat: IgG testing is not a substitute for medical evaluation of true allergies or chronic conditions.
