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.
