Abstract

The aim of this study was to screen how rapidly the human gut microbiota responds to diet in an in vitro model of the proximal colon (TIM-2 system). Two experimental diets were provided to the gut bacteria: a high carbohydrate and a high protein diet. The metabolic response and the composition of the microbiota were compared to a control diet simulating an average western meal. Short-chain and branched-chain fatty acids (SCFA and BCFA, respectively) production, in addition to changes in the community composition (profiling), were measured. The activity of the microbiota reflected differences between diets, exhibiting a trade-off between saccharolytic and proteolytic fermentation when compared to the control. Diversity analysis revealed a phylum-specific response depending on the diet tested. Most changes in the microbiome composition occurred during the first 24 h of the experiment. The outcome of this study elucidates the fact that human gut bacteria quickly respond to changes in diet. In addition, it confirms that variations in the concentration of carbohydrates and proteins modify the activity and composition of the microbiota, and these changes can potentially have an impact on the health of the host.

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?

  • Short term consumption of a mostly animal or mostly plant diet can dramatically alter the microbiota composition and function, as fast as 24 hours.

    “Short term consumption of a mostly animal or mostly plant diet can dramatically alter the microbiota composition and function [26], as fast as 24 hours [27].”
  • Microbial-derived BCFAs, isovalerate, and isobutyrate have been linked to epithelial physiology and the mucosal immune system.

    “Microbial-derived BCFAs, isovalerate, and isobutyrate have been linked to epithelial physiology and the mucosal immune system (380, 382, 383).”
  • BCFAs could be especially important microbial messengers in scenarios of high-protein, low-complex carbohydrate consumption, as studies have shown that consumption of these diets can increase microbial production of BCFAs.

    “BCFAs could be especially important microbial messengers in scenarios of high-protein, low-complex carbohydrate (i.e., dietary fiber) consumption, as studies have shown that consumption of these diets can increase the microbial production of BCFAs (121, 380, 381).”

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.
