What do studies say about Mikrobiom Ernährung?

Studies on microbiome nutrition indicate that a Mediterranean-style diet rich in fiber (whole grains, legumes, olive oil, nuts, berries) consistently improves gut microbial diversity, boosts short-chain fatty acid (SCFA) production, and reduces inflammatory markers such as hs-CRP and IL-6. The evidence ranges from human-strong to human-moderate, with mechanistic animal and in-vitro studies filling causal gaps. However, many commercial 'microbiome diets' lack robust evidence and are driven by marketing. Measuring microbiome markers (Shannon index, SCFAs) can be useful, but assay variability exists across laboratories. Importantly, not every diet marketed as 'microbiome-friendly' is scientifically validated. The Mediterranean diet currently has the strongest support. Be cautious of overblown claims – individual genetics and lifestyle factors also play a significant role.
