Myths vs facts: Leaky Gut Test and Langlebigkeit

Myths vs. Facts: Leaky Gut Test and Longevity Myth: A leaky gut test (e.g., measuring zonulin in stool) can reliably indicate increased intestinal permeability and predict a higher risk of chronic diseases and shortened lifespan. Fact: The scientific evidence for commercial leaky gut tests is weak. Zonulin is not a validated biomarker for intestinal permeability in routine diagnostics; levels fluctuate due to diet, medications, and stress. Even if permeability is increased, the direct link to longevity is unproven. Longevity is influenced by a complex interplay of genetics, lifestyle, environment, and chance – a single stool test cannot provide meaningful predictions. Most consumer tests lack clinical validation and are not endorsed by major medical organizations. Instead, focus on evidence-based strategies: balanced nutrition, regular exercise, quality sleep, and stress reduction – these have demonstrated effects on healthspan and lifespan.
