Can IgG Unverträglichkeitstest help with Langlebigkeit?

No, an IgG intolerance test is not helpful for longevity and may even be harmful. IgG-based food tests are often marketed as 'intolerance tests' but are not scientifically validated for diagnosing true allergies or intolerances. Elevated IgG levels typically reflect normal immune exposure to frequently eaten foods – they are not a sign of disease. The evidence is clear: professional societies like the European Academy of Allergy and Clinical Immunology (EAACI) advise against such tests. For longevity, relevant factors include a balanced diet, exercise, sleep, and stress management – not avoiding IgG-positive foods. Unnecessary dietary restrictions based on these tests can lead to nutrient deficiencies, harming long-term health. If you suspect a real intolerance or allergy, consult a doctor or allergist and use validated methods like skin prick tests or double-blind placebo-controlled food challenges. An IgG test provides no actionable information for an anti-aging or longevity strategy.
