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

The INFINITY DNA-Test including a 28-day plan and recipe book is marketed for gut health. However, the scientific evidence for such a combined approach is weak. DNA tests can identify certain genetic variants related to food intolerances or metabolic pathways (e.g., lactose intolerance, FTO), but their predictive power for individual gut health is limited. The gut microbiome is more strongly influenced by diet, environment, and lifestyle than by genetics. A 28-day plan with a recipe book may promote generally healthy eating habits, but claims of personalization based on DNA are overstated. Clinical trials for such combination products are lacking. Consumers should remain critical: results serve more as inspiration than medical advice. For actual gut issues, a microbiome test or medical consultation is more appropriate.
