What to watch with IgG Unverträglichkeitstest and longevity?

IgG food sensitivity tests are controversial and not recommended by major medical organizations for diagnosing food intolerances or allergies. IgG antibodies are produced in response to many foods as a normal immune reaction, so positive results often have no clinical relevance. Regarding longevity, there is no credible evidence that avoiding foods based on IgG test results extends lifespan or improves long-term health. Instead, focus on proven longevity strategies: a balanced diet rich in plants, regular physical activity, maintaining a healthy weight, and avoiding smoking. Be cautious of commercial tests that may lead to unnecessary dietary restrictions without benefit.
