The Claim

Chronic consumption of aspartame in rodent models is associated with elevated levels of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) in blood, brain, liver, and adipose tissue, along with activation of NF-κB and NLRP3 inflammasome pathways, suggesting a potential mechanistic link to systemic inflammation.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges
0score

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

If rodents eat aspartame over a long time, their bodies seem to show more signs of inflammation in the blood, brain, liver, and fat tissue, and some internal alarm systems that trigger inflammation get turned on.

What the research says

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

    This study looked at many experiments on mice and rats that ate aspartame, and found that it often made their bodies produce more inflammation-related chemicals — just like the claim says.
