acesulfame-K does not raise blood glucose
Part of: • acesulfame-K
Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: All trials, pooled (Meta-analysis)
How the studies fall
What the evidence shows
Acesulfame-K is glycemically inert: it isn't metabolized for energy and RCTs plus a network meta-analysis of non-nutritive-sweetened beverages show no meaningful acute rise in glucose or insulin (blends containing Ace-K actually blunt the insulin response versus sugar). Its debated effects are on the microbiome/appetite, not on acute blood sugar. measured_by:: [[blood glucose]]

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
