ist kefir gesund — can a microbiome test help?

Kefir is generally considered healthy due to its probiotic content, which may support gut health, digestion, and immune function. Evidence from human studies is moderate: some RCTs show benefits for lactose digestion, inflammation, and gut microbiota diversity, but effect sizes are small and results vary. A microbiome test (e.g., from MyBody-X) can profile your gut bacteria, but its clinical utility for guiding kefir consumption is limited. The test is not validated for children and lacks strong evidence for actionable recommendations. For most adults, kefir is safe in moderation; those with compromised immunity or severe GI conditions should consult a doctor. In summary, kefir can be a healthy addition to a balanced diet, but a microbiome test is not a necessary or evidence-based tool to determine whether you should drink it. The evidence for kefir's health effects is human-moderate; the test's added value for this question is primarily marketing.
