What to watch with IgG Unverträglichkeitstest and blood sugar?

IgG food intolerance tests are not supported by mainstream medical guidelines. Organizations like the European Academy of Allergy and Clinical Immunology (EAACI) caution against their use because IgG antibodies to foods are often a normal physiological response and do not reliably indicate intolerance or allergy. Relying on such tests can lead to unnecessary dietary restrictions and nutritional deficiencies. Regarding blood sugar: IgG tests are not designed to assess glycemic control or diabetes risk. If you experience blood sugar fluctuations, it is essential to use validated methods such as fasting glucose, HbA1c, or continuous glucose monitoring (CGM) under medical supervision. There is no robust evidence that IgG-based elimination diets improve blood sugar regulation. For metabolic health, focus on a balanced diet with adequate fiber, regular physical activity, and evidence-based diabetes prevention strategies. Always consult a healthcare professional before making significant dietary changes based on unvalidated tests.
