The Effect of Chewing Duration on Blood Glucose Levels

Status Completed

Clinical Trial Summary

This study aims to assess the impact of speed of consumption of two starch-based foods varying in fibre content on blood glucose levels in normal healthy subjects. Furthermore, the mediating roles of salivary amylase and particle size on blood glucose levels will be studied. The study has a randomized cross-over design. Subjects consume two test-lunches (chick peas and brown rice) in duplicate on 8 different test days, at either long or short chewing duration. Glucose responses will be monitored via a continuous glucose monitoring device and expectorated boluses will be collected during each test day for assessments of amylase activity and food particle size.

Clinical Trial Description

Research suggests that high glucose level variability and large dips in glucose levels may have a negative impact on cognitive function and self-reported wellbeing. The way food is consumed (e.g. chewing duration) may regulate blood glucose levels. The underlying mechanism that links consumption speed to metabolic responses, satiation and health is largely unknown. This study aims to assess the impact of speed of consumption of two starch-based foods varying in fibre content, on blood glucose levels in normal healthy subjects. Furthermore, the mediating roles of salivary amylase and particle size on blood glucose levels are studied. The study has a randomized cross-over design. Each subject consumes two different test-lunches (chick peas and brown rice) in duplicate at either long or short duration. Their breakfast will be standardized during these 8 test days. For a duration of 12 days, blood glucose levels will be monitored via a continuous glucose device. Furthermore expectorated boluses will be collected for assessment of amylase activity and food particle size. ;
