Abstract

Objective: The consumption of an agrarian diet is associated with a reduced risk for many diseases associated with a ‘Westernised’ lifestyle. Studies suggest that diet affects the gut microbiota, which subsequently influences the metabolome, thereby connecting diet, microbiota and health. However, the degree to which diet influences the composition of the gut microbiota is controversial. Murine models and studies comparing the gut microbiota in humans residing in agrarian versus Western societies suggest that the influence is large. To separate global environmental influences from dietary influences, we characterised the gut microbiota and the host metabolome of individuals consuming an agrarian diet in Western society. Design and results: Using 16S rRNA-tagged sequencing as well as plasma and urinary metabolomic platforms, we compared measures of dietary intake, gut microbiota composition and the plasma metabolome between healthy human vegans and omnivores, sampled in an urban USA environment. Plasma metabolome of vegans differed markedly from omnivores but the gut microbiota was surprisingly similar. Unlike prior studies of individuals living in agrarian societies, higher consumption of fermentable substrate in vegans was not associated with higher levels of faecal short chain fatty acids, a finding confirmed in a 10-day controlled feeding experiment. Similarly, the proportion of vegans capable of producing equol, a soy-based gut microbiota metabolite, was less than that was reported in Asian societies despite the high consumption of soy-based products. Conclusions: Evidently, residence in globally distinct societies helps determine the composition of the gut microbiota that, in turn, influences the production of diet-dependent gut microbial metabolites.

  • Some intervention and cross-sectional studies found only modest microbiota differences between omnivores and vegetarians, with the largest effects at genus and species level and little effect on broader measures such as diversity and richness.

    “some intervention and cross-sectional studies have observed only modest microbiota differences between omnivores and vegetarians and suggest that the effects of dietary pattern on the microbiota are greatest at the genus and species level and relatively minimal on broader compositional features, such as diversity and richness (65–67)”
  • Long-term dietary habits are a dominant determinant of an individual's gut microbiota composition.

    “long-term dietary habits are a dominant force in determining the composition of an individual’s gut microbiota”
  • Negligible differences were recently found between the gut microbiota of a small US cohort of omnivores and vegans.

    “Negligible differences were recently found between the gut microbiota of a small-size cohort of omnivore and vegan individuals in the USA.7”
  • Wu et al reported negligible differences in faecal microbiota composition and plasma SCFA profiles in 15 vegan and 16 omnivore subjects, and found no evidence for diet-driven separations in either measure.

    “Wu et al 7 recently reported negligible differences in the faecal microbiota composition and plasma SCFA profiles in 15 vegan and 16 omnivore subjects, and found no evidence for dietdriven separations in either measure.”
  • Prevotella levels were not significantly different between omnivores and vegans.

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.
