Evidence check: IgG Unverträglichkeitstest in the context of Blutzucker

IgG food intolerance tests are often marketed for blood sugar optimization, but the scientific evidence is weak. Measured IgG antibodies usually reflect normal immune exposure, not true intolerance or allergy. For blood sugar management, established markers like HbA1c, fasting glucose, and postprandial glucose are relevant, not IgG. Studies show no clinically useful link between IgG profiles and glycemic control. Caution: IgG tests can lead to unnecessary dietary restrictions and risk of nutrient deficiencies. If you want to improve blood sugar, focus on evidence-based strategies: high-fiber diet, glycemic index awareness, exercise, and medically supervised medication if needed. An IgG test does not replace proper blood sugar diagnostics.
