Mice that drank aspartame or sucralose had more liver inflammation than mice drinking plain water, but mice drinking Reb M had the least inflammation.
Claim Context
In C57BL/6 male mice on a high-fat diet, consumption of aspartame and sucralose was associated with increased liver inflammation scores compared to water controls, while Reb M and water showed the lowest inflammation.
“The lowest inflammation score was recorded in mice exposed to water and Reb M. Mice drinking either aspartame or sucralose had 3.5-fold increase in their inflammation score compared to the score of water group.”

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
That aspartame and sucralose directly cause liver inflammation in obese mice.
A double-blind RCT in 100 C57BL/6 male mice on high-fat diet, randomized to aspartame (411.75 mg/L), sucralose (179.5 mg/L), Reb M (536.25 mg/L), or water, with liver histology scored by blinded pathologist at week 20 as primary endpoint.
Dose-response relationship between NNS exposure and liver inflammation over time.
A prospective cohort study in 150 C57BL/6 male mice on high-fat diet, exposed to 0, 100, 200, 411.75, and 800 mg/L aspartame or sucralose for 24 weeks, with liver inflammation scored at weeks 8, 16, and 24.
Whether mice with high liver inflammation after NNS exposure have distinct serum cytokine or gut permeability profiles.
A case-control study comparing 30 mice with highest inflammation scores to 30 with lowest, measuring serum TNF-α, IL-6, and intestinal permeability markers (FITC-dextran).
The association between NNS type and liver inflammation score at a single time point.
A cross-sectional analysis of 100 mice at week 20, comparing mean liver inflammation scores across NNS groups using ANOVA.
An extreme case of severe liver inflammation in a single mouse after aspartame exposure.
A case report of a single mouse with grade 4 inflammation (highest score) after aspartame, with full histopathology, cytokine, and microbiome profiling.
