High-intensity sweetener consumption and gut microbiome content and predicted gene function in a cross-sectional study of adults in the United States
Abstract
Purpose To evaluate gut microbiome in relation to recent high-intensity sweetener consumption in healthy adults.Methods Thirty-one adults completed a four-day food record and provided a fecal sample on the fifth day. Bacterial community in the samples was analyzed using multitag pyrosequencing. Across consumers and nonconsumers of aspartame and acesulfame-K, bacterial abundance was compared using nonparametric statistics, and bacterial diversity was compared using UniFrac analysis. Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) was used to predict mean relative abundance of gene function.Results There were seven aspartame consumers and seven acesulfame-K consumers. Three individuals overlapped groups, consuming both sweeteners. There were no differences in median bacterial abundance (class or order) across consumers and nonconsumers of either sweetener. Overall bacterial diversity was different across nonconsumers and consumers of aspartame (P < .01) and acesulfame-K (P = .03). Mean predicted gene abundance did not differ across consumers and nonconsumers of aspartame or acesulfame-K.Conclusions Bacterial abundance profiles and predicted gene function were not associated with recent dietary high-intensity sweetener consumption. However, bacterial diversity differed across consumers and nonconsumers. Given the increasing consumption of sweeteners and the role that the microbiome may have in chronic disease outcomes, work in further studies is warranted.

“Although earlier human studies indicated detrimental effects on microbial diversity and composition (99, 100) and a more recent study linked consumption of nonnutritive sweeteners to a “dysbiosis” [an increasingly redundant term in microbiome research (171)] and a decrease in butyrate concentration (172), some reports have concluded that no clear effects of sweeteners on the microbiota can be”

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.
