简要总结
This study was an open, 5-treatment, 5-sequence, 5-day cross-over randomized design clinical trial. The present study was carried out to compare the effects of white rice, brown rice, and black rice on postprandial glucose and lipid profiles in healthy human subjects, using a white bread as a positive control.
详细描述
After a 12-hour fast, oral glucose and meal tolerance was measured with blood samples drawn at times 0, 15, 30, 45, 60, 90, 120, 150 and 180 minutes and TG was at time 0, 1, 2, 3, 4, 5 and 6 hours.
- Serum levels of glucose, insulin, and TG were analyzed by biochemical autoanalyzer. The area under the curve (AUC) changes in blood glucose, TG were computed by the trapezoidal method.
- Glycemic index(GI): the area under the glucose response curve after consumption of a test food divided by the area under the curve after consumption of a control food containing the same amount of carbohydrate and calculated using 50 g glucose as the reference.

结局指标
主要结局
1. Glucose, insulin AUC(incremental area under the curve) 2. Glycemic index(GI)
时间窗: 2 hour postprandial blood glucose, insulin
1. Plasma glucose and insulin will be measured at baseline, 15, 30, 45, 60, 90, 120, 180 and 240 minutes post ingestion of each test solution, and area under the curve will be calculated. 2. Glycemic index (GI) was defined as the area under the glucose response curve after consumption of a test food divided by the area under the curve after consumption of a control food containing the same amount of carbohydrate and calculated using 50 g glucose as the reference. Plasma glucose will be measured at baseline, 15, 30, 45, 60, 90, and 120 minutes post ingestion of each test solution. GI= (incremental blood glucose area of test meal/incremental area of glucose) × 100
次要结局
- Triglyceride iAUC(incremental area under the curve)(6 hour postprandial blood triglyceride(TG))
