The Claim
Higher consumption of artificial sweeteners, particularly aspartame and acesulfame-K, is associated with a 13% to 15% increased risk of overall cancer in adults.
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.
Adults who consume more artificial sweeteners like aspartame and acesulfame-K have a 13% to 15% higher rate of developing cancer compared to those who consume less.
See the scientific wording
Higher consumption of artificial sweeteners, particularly aspartame and acesulfame-K, is associated with a 13% to 15% increased risk of overall cancer in adults, based on data from 102,865 participants in the NutriNet-Santé cohort followed for a median of 7.8 years, after adjusting for age, sex, BMI, smoking, physical activity, and dietary factors.
Artificial sweeteners change the balance of bacteria in the gut, which weakens the gut lining. This allows harmful substances to enter the bloodstream, triggering chronic inflammation and damaging DNA in cells, which can lead to cancer.
What the research says
1 studyPeople who drink a lot of diet sodas and eat foods with artificial sweeteners like aspartame and acesulfame-K were slightly more likely to get cancer over time, even when scientists accounted for things like weight, smoking, and diet. This doesn’t mean sweeteners cause cancer, but they might be linked to a small increase in risk.
