Urinary artificial sweeteners and breast cancer risk in women from the Moli-sani Study

Cohort Study

Human

The study found that while most artificial sweeteners weren't linked to breast cancer, women who had sucralose in their urine were more likely to develop breast cancer before menopause, which goes against the claim that these sweeteners are completely safe.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Among middle-aged women in a big health study, the artificial sweetener saccharine shows up the most in their urine — making up over two-thirds of all sweetener exposure — followed by a natural sweetener from stevia.
