Subjects in this group drank "water" 10 min before drinking a glucose load on their first oral glucose tolerance test (OGTT) and drank "sucralose" 10 min before drinking a glucose load on their second OGTT. The two OGTT were separated on average by 1 week (i.e. washout was approximately 1 week).

60 ml of water were drank 10 min before doing a OGTT

we will measure plasma insulin concentrations during a 5-hour modified Oral Glucose Tolerance Test (mOGTT) administered 10 minutes after subjects consume sucralose in water or an equal volume of water without sucralose (control condition).Plasma insulin concentrations were measured at 20, 15, 10, 6, and 2 min before and at 10, 20, 30, 40, 60, 90, 120, 150,180, 240, and 300 min after ingesting 75g of glucose. All these data collected were used to create the AUC curve.
