Even artificial sweeteners that don’t contain sugar can make some people’s bodies release insulin just from tasting them.

Assessment Explanation
The abstract implies sucralose 'can induce' CPIR, but the data show only peak responses in individuals were significant—this is not a consistent effect. The verb 'can induce' overstates the evidence.
More Accurate Statement
“Non-glucose sweeteners like sucralose are associated with cephalic phase insulin release in some individuals, despite lacking glucose, suggesting that sweet taste perception alone may trigger this response in a subset of people.”
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.
Evidence from Studies
Supporting (1)
Sweet stimuli induce cephalic phase insulin release to varying degrees in humans.
Even though sucralose doesn’t have sugar, some people’s bodies still released insulin when they tasted it—just because it tasted sweet. The study shows that sweet taste alone can trick the body into preparing for sugar, even if there’s no sugar present.
