Evidence check: INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch in the context of Blutzucker

The 'INFINITY DNA-Test' is marketed as a comprehensive product combining genetic analysis with a 28-day plan and recipe book, specifically in the context of blood sugar. The idea of personalizing diet based on genetic markers is popular, but the scientific evidence for such direct DNA-based dietary recommendations for blood sugar control is weak. While genes like TCF7L2 are associated with type 2 diabetes, the effect sizes of individual variants are small, and translation to individual daily life is not clinically validated. The included 28-day plan and recipe book may promote generally healthy eating principles (e.g., low glycemic index, high fiber), but they are not substantiated by the DNA results specifically. Without controlled trials demonstrating benefit of this specific product over standard dietary advice, it remains primarily a marketing tool. Consumers should have realistic expectations: the test cannot guarantee personalized blood sugar management. Medical supervision is essential for existing metabolic conditions.
