was ist epigenetik — can a microbiome test help?

Epigenetics refers to heritable changes in gene activity that do not involve alterations to the DNA sequence, such as DNA methylation or histone modifications. A microbiome test analyzes the composition of gut bacteria. There is evidence that the microbiome can influence epigenetic processes (e.g., via short-chain fatty acids), but a commercial microbiome test cannot directly measure epigenetic changes. The predictive power of such tests for individual health decisions is currently limited. Studies show associations, but not causal, personalized recommendations. For lifestyle optimization, focus on established factors like fiber intake, exercise, and stress reduction. A microbiome test may serve as a rough orientation – not as a diagnostic or therapeutic tool.
