The gut microbiota at the intersection of diet and human health

Open access
Gentile, Christopher L., Weir, Tiffany L.·2018·Science

Abstract

Diet affects multiple facets of human health and is inextricably linked to chronic metabolic conditions such as obesity, type 2 diabetes, and cardiovascular disease. Dietary nutrients are essential not only for human health but also for the health and survival of the trillions of microbes that reside within the human intestines. Diet is a key component of the relationship between humans and their microbial residents; gut microbes use ingested nutrients for fundamental biological processes, and the metabolic outputs of those processes may have important impacts on human physiology. Studies in humans and animal models are beginning to unravel the underpinnings of this relationship, and increasing evidence suggests that it may underlie some of the broader effects of diet on human health and disease.

    The Hadza's microbiota and health advantages cannot be attributed to low carbohydrate intake alone, because their diet is rich in plant-derived MACs and their microbiota is rich in carbohydrate-metabolizing bacteria.

    “it is difficult to ascribe these microbiota and health benefits to lower CHO intake by itself because the Hadza diet is rich in plant-derived MACs, and their microbiota contains a high abundance of CHO-metabolizing bacteria (63)”

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

  • A mouse study demonstrated that microbial changes leading to metabolic endotoxemia were induced by a lack of fermentable fibre rather than dietary fat content.

    “This state has often been attributed to a high-fat diet, though a mouse study demonstrated that microbial changes leading to this detrimental state were induced by a lack of fermentable fibre rather than dietary fat content [97,98].”
  • The gut microbiota plays a critical role in regulating body function by producing diverse metabolites and influencing the gut-liver-brain axis and immune system pathways.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-07.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-07.

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.
