Abstract

The discovery of gut sweet taste receptors has led to speculations that non-nutritive sweeteners, including sucralose, may affect glucose control. A double-blind, parallel, randomized clinical trial, reported here and previously submitted to regulatory agencies, helps to clarify the role of sucralose in this regard. This was primarily an out-patient study, with 4-week screening, 12-week test, and 4-week follow-up phases. Normoglycemic male volunteers (47) consumed ∼333.3 mg encapsulated sucralose or placebo 3x/day at mealtimes. HbA1c, fasting glucose, insulin, and C-peptide were measured weekly. OGTTs were conducted in-clinic overnight, following overnight fasting twice during screening phase, twice during test phase, and once at follow-up. Throughout the study, glucose, insulin, C-peptide and HbA1c levels were within normal range. No statistically significant differences between sucralose and placebo groups in change from baseline for fasting glucose, insulin, C-peptide and HbA1c, no clinically meaningful differences in time to peak levels or return towards basal levels in OGTTs, and no treatment group differences in mean glucose, insulin, or C-peptide AUC change from baseline were observed. The results of other relevant clinical trials and studies of gastrointestinal sweet taste receptors are compared to these findings. The collective evidence supports that sucralose has no effect on glycemic control.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
