Risks and limits of IgG Unverträglichkeit Frauen

IgG food intolerance tests are often marketed to women as a way to identify 'hidden' food sensitivities. However, the scientific evidence is weak: IgG antibodies indicate prior exposure to food proteins, not intolerance or allergy. True food allergies are IgE-mediated. Studies show that IgG-guided elimination diets rarely improve symptoms and may lead to unnecessary dietary restrictions. For women, risks include nutritional deficiencies during pregnancy, lactation, or menopause, as well as increased anxiety around eating. The tests lack standardization and reproducibility. Major medical organizations (e.g., EAACI, DGAKI) advise against using IgG tests for diagnosing food intolerance. A more evidence-based approach is to keep a symptom diary and, if needed, undergo a medically supervised elimination diet followed by a double-blind placebo-controlled food challenge. In summary, IgG tests are not reliable and can cause more harm than good, especially for women with higher nutritional demands.
