MyBody-X angle on Ballaststoffe Check

The MyBody-X fiber check claims to assess your individual fiber needs or status. However, the scientific basis for such tests is often weak. Fiber is crucial for gut health, but a single test cannot reliably determine your personal requirement. Evidence for personalized fiber recommendations from DNA or microbiome tests is limited (evidence: mixed). General guidelines (e.g., 30 g/day for adults) are well-supported. Be cautious of exaggerated claims: a test does not replace medical advice, especially if you have digestive issues.
