Determination of the GI and II Values of Soft Drink and Soft Drink With Sugardown™

Overview

This study was a partly controlled laboratory-based study comparing the glycemic and insulinemic indices of 3 test meals containing soft drink alone or with SUGARDOWN™ (Galactomannan) in overweight adults.

STUDY SUMMARY This study was a partly controlled, laboratory-based study comparing the short-term postprandial glucose and insulin responses produced by three test meals containing soft drink consumed alone or with SUGARDOWN™, relative to the responses produced by an equal-carbohydrate portion of glucose solution (the reference food). The study used a repeated measures design, such that every subject consumed the reference food and each test food on two separate occasions, completing a total of eight separate test sessions. Each subject completed their test sessions on separate weekday mornings at a similar time each day, as close as possible to the time they would normally eat breakfast. SUBJECTS Ten healthy, non-smoking, overweight or obese subjects (6 females and 4 males) voluntarily participated in this study. The mean ± SD age of the subjects was 32.4 ± 10.9 yr (range: 18.7 - 55.6 yr), and their mean ± body mass index value was 27.4 ± 2.6 kg/m2 (range: 25.3 - 32.3 kg/m2). Volunteers were given detailed written and verbal information about all of the study's inclusion criteria and experimental procedures. If the volunteers decided that they would like to participate in the study, they were asked to come to the research centre on another morning, where they completed a detailed screening questionnaire that assessed their current health status and medical history. In order to participate in the study, the volunteers had to meet the inclusion criteria. All suitable volunteers that were invited to participate in the study were required to sign a detailed subject information sheet and a consent form before commencing any experimental procedures.
