Abstract

Non-caloric artificial sweeteners (NAS) are among the most widely used food additives worldwide, regularly consumed by lean and obese individuals alike. NAS consumption is considered safe and beneficial owing to their low caloric content, yet supporting scientific data remain sparse and controversial. Here we demonstrate that consumption of commonly used NAS formulations drives the development of glucose intolerance through induction of compositional and functional alterations to the intestinal microbiota. These NAS-mediated deleterious metabolic effects are abrogated by antibiotic treatment, and are fully transferrable to germ-free mice upon faecal transplantation of microbiota configurations from NAS-consuming mice, or of microbiota anaerobically incubated in the presence of NAS. We identify NAS-altered microbial metabolic pathways that are linked to host susceptibility to metabolic disease, and demonstrate similar NAS-induced dysbiosis and glucose intolerance in healthy human subjects. Collectively, our results link NAS consumption, dysbiosis and metabolic abnormalities, thereby calling for a reassessment of massive NAS usage.

  • Non-nutritive sweetener consumption induced glucose intolerance in a microbiota-dependent manner in rodents and humans.

    “NNS consumption induced glucose intolerance in a microbiota-dependent manner (56).”
  • Emulsifiers and artificial sweeteners can promote metabolic syndrome features in mice by modulating the microbiota.

    “Emulsifiers and artificial sweeteners have been shown to be involved in the development of metabolic syndrome features through their modulation of the microbiota in mice46,47.”
  • In seven people, high-dose artificial sweeteners caused insulin resistance after 7 days.

    “In a study in seven people, artificial sweeteners given at high doses resulted in insulin resistance after only 7 days47”
  • Chronic non-caloric artificial sweetener consumption in mice impacts gut microbial community structure, increasing Bacteroides and some Clostridiales.

    “Chronic NAS consumption in mice was shown to impact gut microbial community structure133, resulting in an increase in abundance of bacteria belonging to the Bacteroides genus and some members of the Clostridiales order.”
  • Germ-free mice colonized with gut microorganisms from NAS-treated mice or stool microorganisms exposed to NAS ex vivo develop glucose intolerance.

    “germ-free mice colonized with gut microorganisms from NAS-treated mice or stool microorganisms exposed to NAS ex vivo develop glucose intolerance.”

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.
