Abstract

To address how the microbiome might modify the interaction between diet and cardiometabolic health, we analyzed longitudinal microbiome data from 307 male participants in the Health Professionals Follow-Up Study, together with long-term dietary information and measurements of biomarkers of glucose homeostasis, lipid metabolism and inflammation from blood samples. Here, we demonstrate that a healthy Mediterranean-style dietary pattern is associated with specific functional and taxonomic components of the gut microbiome, and that its protective associations with cardiometabolic health vary depending on microbial composition. In particular, the protective association between adherence to the Mediterranean diet and cardiometabolic disease risk was significantly stronger among participants with decreased abundance of Prevotella copri. Our findings advance the concept of precision nutrition and have the potential to inform more effective and precise dietary approaches for the prevention of cardiometabolic disease mediated through alterations in the gut microbiome.

  • Microbiome-mediated links between diet and health have been prevalently investigated by considering the role of the abiotic components of foods.

    From Unexplored microbial diversity from 2,500 food metagenomes and links with the human microbiome. (2024) · cites this paper as [37]

    The Results section (page unavailable) investigates dietary components such as fiber and pectin in relation to microbial functions, and the Discussion links Mediterranean diet adherence, the microbiome, and cardiometabolic risk. This supports the paper as an example of studying nonliving food components, but it does not establish that such an approach has been prevalent across diet–microbiome–health research.

  • SCFAs produced by the gut microbiota during fermentation of dietary fiber are critical in the reinforcement of the mucus layer.

  • High-fiber intake increases dietary fiber metabolizers and SCFAs producers, which in turn stimulates mucus secretion to maintain a well-structured and intact mucus layer.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
