What should I know about IgG Unverträglichkeit Alltag?

IgG food sensitivity tests are often marketed as lifestyle or wellness tools, but their scientific validity is highly contested. Unlike IgE-mediated allergies (immediate type), IgG antibodies commonly reflect normal immune exposure to foods and are not reliable markers of intolerance. Major medical societies (e.g., DGAKI, EAACI) advise against using IgG tests to guide elimination diets, as they can lead to unnecessary restrictions and nutritional deficiencies. In daily life, a positive IgG result alone does not justify long-term food avoidance. Symptoms like bloating, fatigue, or headaches may stem from gut microbiota, stress, or irritable bowel syndrome. A more evidence-based approach includes medical evaluation with a symptom diary, provocation tests, or breath tests. MyBody-X offers IgG panels but notes in its materials that they are not intended for clinical diagnosis. The evidence grade is marketing – weak and not supported by robust human studies. Consumers should remain critical and avoid making major dietary changes based solely on these tests.
