The Claim
In the NutriNet-Santé cohort, aspartame and acesulfame-K are the most commonly consumed artificial sweeteners, accounting for 58% and 29% of total artificial sweetener intake respectively, and both are consistently associated with increased cancer risk, while sucralose is not significantly associated with cancer risk.
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.
In a large French health study, aspartame and acesulfame-K were the most common artificial sweeteners consumed and were linked to higher cancer rates, while sucralose showed no such link.
See the scientific wording
Aspartame and acesulfame-K are the most commonly consumed artificial sweeteners in the NutriNet-Santé cohort, contributing 58% and 29% of total intake, respectively, and both show consistent associations with increased cancer risk, while sucralose shows no significant association.
Aspartame and acesulfame-K change the types of bacteria in the gut, making the intestinal barrier leaky. This lets harmful substances enter the bloodstream, triggering chronic inflammation and damaging DNA in cells, which can lead to cancer. Sucralose does not cause these changes.
What the research says
1 studyThis study found that people who drank a lot of diet sodas with aspartame or acesulfame-K had a slightly higher chance of getting cancer, while those who drank sweeteners like sucralose didn’t show the same risk—just like the claim says.
