Clinical Trial Summary

The purpose of this study is to assess the glycaemic controlling effects of BSG and bio-transformed BSG-containing biscuits in Singapore adults with MetS. The investigators hypothesized that consumption of BSG and bio-transformed BSG containing biscuit will improve glycaemic control.

Description:

This is a double-blind, randomised, crossover experiment. During the 3-week, 19 subjects will participate in a 3 meal tolerance test (MTT). During each MTT session, all subjects are required to consume 90 g biscuits (either control, autoclaved BSG or bio-transformed BSG biscuits) and monitored over a period of 240 minutes. All three types of biscuits will be consumed at a randomised sequence during this 3-week period. Post-prandial blood glucose, insulin, lipid and amino acid responses, breath analysis, body composition, blood pressure, appetite assessment, and any other glycaemic biomarkers will be assessed.
