简要总结
The aim of the study is to compare Diabetec® Fibre Grains (FIbre Grains) in a mixed meal setting with Jasmine rice. This is to see whether partial replacement of white rice with Fibre Grains can reduce postprandial blood glucose control.
详细描述
Lifestyle modification, in particular adopting an appropriate dietary pattern, is generally accepted as the cornerstone for the treatment of people with type 2 diabetes. Consumption of low GI food has shown to improve glycemic control, lipid profile and reduce systemic inflammation. However, there are few dietary intervention studies attempting to change the GI of food by changing the staple carbohydrates. In this study, formulated rice with special fibre enrichment, Fibre Grains, was used to replace rice as the staple carbohydrates in one's diet. This fibre enriched rice has been previously tested to have a lower GI than normal rice while still able to preserve all the sensory characteristics of normal rice. With rice being a staple to Asians, this specially formulated fibre enriched rice offers a lower GI alternative to the conventional rice without affecting the people dietary preference.

结局指标
主要结局
Change in glucose response
时间窗: 2 hour
A mixed meal tolerance test will be done to collect blood samples for glucose analysis at 0 min, 15 min, 30 min, 45 min, 60 min , 90 min and 120 min.The change in glucose response will be measured by comparing incremental area under the curve (iAUC) after ingestion of Fibre Grain meal and control Jasmine white rice meal.
