wie kann ich mein mikrobiom verbessern — what does this mean exactly?

The question 'how can I improve my microbiome' is popular but scientifically vague. The microbiome refers to the community of microorganisms in your gut. 'Improvement' is often equated with higher diversity and the presence of beneficial bacteria. However, evidence for specific interventions is limited. A high-fiber diet (vegetables, legumes, whole grains) reliably promotes diversity. Probiotics may help after antibiotics, but effects are strain-specific and not generalizable. Prebiotics (inulin, resistant starch) support existing bacteria. Importantly, a commercial microbiome test like MyBody-X provides a bacterial profile but not a medical diagnosis. According to a 2026 study (Bruins et al.), clinical validity of such DTC tests is limited; users often overestimate actionable insights. Without medical guidance, misinterpretation is common. In summary, a healthy diet is the strongest lever, but individual test results should be interpreted cautiously. The evidence for most microbiome 'improvement' strategies is mechanistic or based on small studies, not large human trials.
