Abstract

The gut microbiota plays an important role in human health by interacting with host diet, but there is substantial inter-individual variation in the response to diet. Here we compared the gut microbiota composition of healthy subjects who exhibited improved glucose metabolism following 3-day consumption of barley kernel-based bread (BKB) with those who responded least to this dietary intervention. The Prevotella/Bacteroides ratio was higher in responders than non-responders after BKB. Metagenomic analysis showed that the gut microbiota of responders was enriched in Prevotella copri and had increased potential to ferment complex polysaccharides after BKB. Finally, germ-free mice transplanted with microbiota from responder human donors exhibited improved glucose metabolism and increased abundance of Prevotella and liver glycogen content compared with germ-free mice that received non-responder microbiota. Our findings indicate that Prevotella plays a role in the BKB-induced improvement in glucose metabolism observed in certain individuals, potentially by promoting increased glycogen storage.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Diet modulates the composition and function of the gut microbiota in humans and other mammals.

    “diet modulates the composition and function of this community of microbes in humans and other mammals18–25”
  • In mice, Prevotella benefits glucose metabolism only if the diet supplies fermentable fibre/polysaccharides; it does not do so on a high-fat or Western-style diet lacking them.

    “Prevotella could also improve the glucose metabolism of mice that were fed carbohydrate-rich diets but not a high-fat diet that was devoid of fermentable polysaccharides.”
  • People vary substantially in how their glucose metabolism reacts to an intervention using whole grains.

    “Similarly, individuals show large differences in glucose metabolism in response to an intervention that is based on whole grains22.”
  • The better glucose tolerance seen with whole grains was mostly attributable to a rise in Prevotella within the microbiota.

    “Improved tolerance to glucose could be explained largely through enrichment of the genus Prevotella within the microbiota.”
  • Several other studies have reported that the baseline diet of an individual predicted the systemic and microbial responses to the diet intervention.

    “Several other studies have reported that the baseline diet of an individual predicted the systemic and microbial responses to the diet intervention (70,514).”

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.
