Evidence check: NutriCare | INFINITY DNA-Test in the context of blood sugar

The NutriCare | INFINITY DNA-Test is marketed as a comprehensive nutrition and health analysis, but in the context of blood sugar, the evidence is weak. The provided knowledge contexts contain no specific markers or studies supporting reliable prediction of blood glucose levels or glycemic response to foods via DNA tests. Current research (GWAS) shows that individual genetic variants (e.g., in TCF7L2, GCKR, SLC30A8) have only small effects on fasting glucose or HbA1c and are insufficient for personalized dietary recommendations. Direct-to-consumer tests often overstate clinical relevance. This test cannot diagnose metabolic disorders like diabetes or replace standard care. Blood sugar is primarily influenced by diet, exercise, sleep, and stress. Without access to the specific marker panel, the test's predictive value remains unclear. I advise skepticism toward marketing claims and recommend relying on established blood glucose measurements (e.g., fasting glucose, HbA1c) and medical guidance.
