Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group 1- Oral solution
Participants will be randomly assigned to drink two oral solutions made of different combinations of saccharin, lactisole, acetaminophen, 3-O-methyl glucose, or glucose.
Dietary: saccharin
Assess the glycemic and hormonal responses to an oral glucose load preceded by an oral solution of NCASs (saccharin).
Estimate glucose absorptions
Indirectly estimate the rate of glucose absorption and gastric emptying by using 3-O-methyglucose (3-OMG) and acetaminophen, respectively.
