Abstract

The gut microbiome is a contributory factor in ageing-related health loss and in several non-communicable diseases in all age groups. Some age-linked and disease-linked compositional and functional changes overlap, while others are distinct. In this Review, we explore targeted studies of the gut microbiome of older individuals and general cohort studies across geographically distinct populations. We also address the promise of the targeted restoration of microorganisms associated with healthier ageing.

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

  • The microbiota and its metabolites are altered during ageing; for example, the abundance of the anti-inflammatory bacterium Faecalibacterium decreases, whereas that of proinflammatory Fusobacterium increases, leading to intestinal inflammation.

    “The microbiota and its metabolites are altered during ageing; for example, the abundance of the anti-inflammatory bacterium Faecalibacterium decreases, whereas that of proinflammatory Fusobacterium increases, leading to intestinal inflammation.234”
  • Late life tertiary succession is marked by declining α- and β-diversity and loss of keystone commensals like Faecalibacterium and Bifidobacterium.

    “Finally, late life ushers in tertiary succession, which is marked by declining α- and β-diversity and loss of keystone commensals like Faecalibacterium and Bifidobacterium.39,40”
  • The composition and activity of the gut microbial ecosystem changes during aging, resulting in a substantial decrease in diversity.

    “However, the composition and activity of this microbial ecosystem undergoes continuous changes during aging, which finally results in a substantial decrease in diversity.”

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.
