Effect of Prebiotic Sodas on Postprandial Levels of GLP-1, PYY, Transit Time and Satiety Levels: A Pilot Study

NCT07362563•Olipop, PBC

View on ClinicalTrials.gov

Summary

The main objective of this study is to evaluate the acute effects of prebiotic sodas on postprandial levels of glucagon-like peptide-1 (GLP-1), peptide YY (PYY), gastric emptying, and satiety levels in healthy adults.

Detailed Description

The primary aim of this clinical trial is to evaluate the effects of single-dose prebiotic sodas on on postprandial levels of GLP-1. Participants (n=15) will be healthy males and healthy, non-pregnant, non-lactating females aged 18-60 years. Participants will consume a single dose of 3 different prebiotic sodas (6 - 9 g dietary fiber and 4 g total sugar per can) and one control soda (0 g dietary fiber and 4 g total sugar per can) in a randomized, crossover design over a period of 4-12 weeks with an interval of at least 1 week and at most 3 weeks between visits. Secondary outcomes will include evaluating the effects of single-dose consumption of the control and prebiotic sodas on postprandial PYY, gastric emptying, and satiety levels.
