The Claim

Consumption of sucralose in rodent models is consistently associated with increased levels of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β), decreased levels of the anti-inflammatory cytokine IL-10, disruption of gut barrier integrity (evidenced by reduced occludin and secretory IgA), elevated circulating lipopolysaccharide (LPS), and alterations in gut microbiota composition, suggesting a potential role in gut-driven systemic inflammation.

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.

How it works
1 study reviewed
In plain English

When rats and mice eat sucralose, a common artificial sweetener, their guts get more inflamed, their intestinal lining gets weaker, and the good and bad bacteria in their intestines change — all of which might cause body-wide inflammation.

Sucralose consumption in rodent models is consistently associated with increased pro-inflammatory cytokines (TNF-α, IL-6, IL-1β), reduced anti-inflammatory IL-10, disrupted gut barrier integrity (lower occludin and secretory IgA), elevated circulating LPS, and altered gut microbiota composition, indicating a potential role in gut-driven systemic inflammation.

1 study
  1. Study: Impact of Artificial Sweeteners on Inflammation Markers: A Systematic Review of Animal Studies

    This study looked at what happens when mice and rats eat sucralose, and found it causes gut problems and more inflammation — just like the claim says.
