Myths vs facts: IgG and Blutzucker

The claim that IgG tests can reveal blood sugar issues or explain them through food intolerances is not supported by science. IgG antibodies to foods are a normal immune response and do not indicate intolerance or allergy. Major allergy societies like EAACI explicitly advise against using such tests. Blood sugar regulation is primarily driven by carbohydrate intake, insulin sensitivity, and lifestyle factors – not by IgG reactions. An IgG test provides no actionable information for blood sugar management and may lead to unnecessary dietary restrictions or false reassurance. To improve blood sugar control, rely on evidence-based approaches: glycemic index, fiber intake, physical activity, and professional guidance. MyBody-X DNA tests also lack validated links to IgG or blood sugar. Be skeptical of marketing that connects IgG with metabolic health.
