The Claim
Consumption of saccharin and sucralose for two weeks at doses below the acceptable daily intake impairs glucose tolerance in healthy adults, as measured by plasma glucose responses, and is associated with distinct alterations in the stool and oral microbiome and plasma metabolome.
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 and sucralose for two weeks at doses below safety limits reduces glucose tolerance in healthy adults and changes the composition of gut and oral bacteria and blood metabolites.
See the scientific wording
Consumption of saccharin and sucralose for two weeks at doses below the acceptable daily intake impairs glucose tolerance in healthy adults, as measured by plasma glucose responses, and is associated with distinct alterations in the stool and oral microbiome and plasma metabolome.
When people consume saccharin or sucralose, the bacteria in their gut and mouth change in type and activity. These altered bacteria produce different chemicals that enter the bloodstream and interfere with how the body manages blood sugar, causing it to rise higher after eating.
What the research says
1 studyStudy: Personalized microbiome-driven effects of non-nutritive sweeteners on human glucose tolerance.
This study found that taking saccharin or sucralose for two weeks—like in diet sodas or sugar-free products—made healthy people’s blood sugar harder to control, and it changed the bacteria in their gut and mouth, plus their blood chemicals. So yes, these sweeteners can affect blood sugar even at normal doses.
