Myths vs facts: NutriCare | INFINITY DNA-Test and gut health

The NutriCare or similar INFINITY DNA test often claims to provide personalized nutrition advice and insights into gut health. Fact: DNA tests can detect genetic variants linked to lactose intolerance, gluten sensitivity, or nutrient metabolism – these associations have strong human evidence for specific genes. Myth: a DNA test can assess your current gut microbiome or diagnose digestive issues. Gut microbiota is dynamic, influenced by diet, lifestyle, and medications; it cannot be read from your DNA. Consumer DNA tests for gut health lack clinical validation for actionable recommendations. MyBody-X offers separate microbiome stool tests that directly measure bacterial composition, which is more relevant. Evidence for gut health claims from DNA alone is mixed at best, often marketing-driven. Caveat: never change medication or diet based solely on a consumer DNA test; consult a healthcare professional for persistent symptoms.
