Soluble Fibre Enriched CHO Food Study
Development of Palatable Soluble Fibre Containing Carbohydrate Foods and Its Effects on Postprandial Blood Glucose Response in Healthy Individuals
Descripción general del estudio
Estado
Descripción detallada
Literature to date points to beneficial glycemic effects from consumption of soluble fibre; however, whole grain products consumption is below recommendations possibly due to the presence of unappealing characteristic organoleptic properties. White, refined products are still the choice of the general public. As such, we propose to investigate the feasibility of increasing health benefits of commonly consumed white, refined carbohydrate products by incorporating a soluble fibre blend.
This research is important to determine the feasibility of developing fibre enriched carbohydrate foods that maintains the original organoleptic properties and is effective in reducing postprandial blood glucose response.
35 subjects will be recruited in phase I to complete a sensory evaluation on the test foods. Following tasting of the control and fibre-enriched samples, data on each subjects' liking or disliking will be collected through a 9-point hedonic scale.
An acute crossover RCT will be conducted in phase II by 10 healthy individuals. Subjects will be randomized to consume one the treatments at each visit and blood glucose levels over 120min and satiety scores will be measured.

Satiety Score
Periodo de tiempo: 3 months
|
The incorporation of viscous soluble fibre in commonly consumed carbohydrate foods will result in increase in subjective satiety compared to non soluble fibre enriched products.
Satiety will be measured using a satiety questionnaire in which you will answer four questions about how full you feel.
