Can IgG Unverträglichkeitstest help with longevity?

An IgG food intolerance test detects antibodies that often reflect normal dietary exposure rather than true intolerance or allergy. Scientific evidence supporting its use for improving longevity is very weak. Longevity is influenced by factors like caloric restriction, Mediterranean diet, exercise, and stress management—not by avoiding IgG-positive foods. Unnecessary dietary restrictions can lead to nutrient deficiencies and social isolation, which may harm health. MyBody-X offers allergy tests (IgE) but does not include IgG tests in its longevity portfolio. From an evidence-based perspective, this test is not recommended for longevity goals. Those seeking to optimize their diet for healthy aging should rely on proven strategies and consult a physician if food intolerances are suspected.
