The Claim
Consumption of non-nutritive sweeteners—saccharin, sucralose, aspartame, and stevia—for two weeks at doses below the acceptable daily intake alters the stool and oral microbiome and plasma metabolome in healthy adults, with each sweetener producing distinct microbial and metabolic signatures.
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.
Consuming saccharin, sucralose, aspartame, or stevia for two weeks at typical low doses changes the bacteria in the gut and mouth and alters the profile of metabolites in the blood, with each sweetener producing a unique pattern.
See the scientific wording
Consumption of non-nutritive sweeteners—saccharin, sucralose, aspartame, and stevia—for two weeks at doses below the acceptable daily intake alters the stool and oral microbiome and plasma metabolome in healthy adults, with each sweetener producing distinct microbial and metabolic signatures.
When people consume artificial sweeteners, the bacteria in their mouth and gut change which types are present and what chemicals they produce. These changed bacteria release different molecules into the bloodstream, and each sweetener causes a unique set of bacterial changes and blood chemicals.
What the research says
1 studyStudy: Personalized microbiome-driven effects of non-nutritive sweeteners on human glucose tolerance.
This study found that taking four common artificial sweeteners for two weeks changed the bacteria in people’s guts and mouths, and also changed the chemicals in their blood—and each sweetener made a different change. So yes, the claim is right.
