A Crossover Study Evaluating the Postprandial Glycemic Response of Three Sweeteners in a Mixed Meal Setting

9. November 2026 aktualisiert von: LOAM Science

A Randomized, Participant-Masked, Crossover Study Evaluating Postprandial Glycemic Response to Three Sweetener Preloads Consumed Before a Standardized Mixed Meal in Healthy Adults

This study is using a double-blind, randomize crossover evaluating the impact of three different sweeteners on postprandial glycemic response in a mixed meal setting. In 50 individuals, postprandial glucose response will be evaluated as a primary objective. Secondary objectives include additional measures of glucose response as well general gastrointestinal response to the sweeteners, assessed through a series of questionnaires.

Maßnahmenbeschreibung
Zeitfenster
Postprandial Area Under the Curve to 120 Minutes
Zeitfenster: Data will be collected on each day of supplementation, days 3, 4, 6, 7, 9, and 10.
