Risks and limits of IgG Unverträglichkeit Männer

IgG food intolerance tests (often marketed as 'food sensitivity' tests) lack scientific validation. Major allergy and immunology societies advise against them because IgG antibodies to foods are usually a marker of exposure and tolerance, not intolerance. For men, there are no specific risks, but the tests can lead to unnecessary dietary restrictions, nutritional deficiencies, and anxiety. No robust clinical trials show benefit. Evidence: marketing/unclear. Caveat: Not diagnostic; avoid using for medical decisions. If digestive issues exist, consult a gastroenterologist for evidence-based testing (e.g., lactose hydrogen breath test, celiac serology).
