Questions people ask about IgG Unverträglichkeit Senioren

IgG food intolerance tests are widely marketed but lack robust scientific validation. IgG antibodies indicate immune exposure—meaning the body has encountered a food—not necessarily intolerance or allergy. In seniors, age-related immune changes can further complicate interpretation. Systematic reviews show no reliable diagnostic accuracy for IgG-based food intolerance testing. False positives may lead to unnecessary dietary restrictions, increasing the risk of malnutrition in older adults. Clinically, established methods like symptom diaries, elimination diets, or breath tests are preferred. MyBody-X does not offer IgG tests; its DNA-based analyses assess genetic predispositions, not active intolerances, and also require cautious interpretation. For seniors, any dietary change should be supervised by a healthcare professional to avoid nutrient deficiencies. The evidence for IgG testing remains weak and is considered a marketing-driven practice rather than evidence-based medicine.
