Post-prandial Glycaemic Controlling Effects of BSG in Singapore Adults With Metabolic Syndrome

November 7, 2023 updated by: Jung Eun Kim, National University of Singapore

Impact of Brewer's Spent Grain (BSG) and Bio-transformed BSG Biscuits on Post-prandial Glycaemic Controlling Effects in Singapore Adults With Metabolic Syndrome

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.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
