The Claim
Gnotobiotic mice transplanted with microbiomes from human responders to non-nutritive sweeteners exhibit glycemic responses that mirror those of their human donors, indicating that microbiome composition is a mediator of individual variability in glucose tolerance to non-nutritive sweeteners.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When mice raised without microbes receive gut bacteria from humans who react strongly to artificial sweeteners, the mice show the same changes in blood sugar levels as those humans.
See the scientific wording
Gnotobiotic mice transplanted with microbiomes from human responders to non-nutritive sweeteners replicate the glycemic responses of their human donors, suggesting that microbiome composition mediates individual variability in glucose tolerance to NNS.
When people consume artificial sweeteners, the bacteria in their gut change in ways that produce different chemicals. These chemicals signal the body to handle sugar less effectively, causing blood sugar levels to rise higher than normal after eating.
What the research says
1 studyStudy: Personalized microbiome-driven effects of non-nutritive sweeteners on human glucose tolerance.
When scientists gave mice the gut bacteria from people whose blood sugar got worse after using artificial sweeteners, the mice also had worse blood sugar control—showing that the bacteria in our guts can change how our bodies react to sweeteners.
