摘要: 目的:评价健康成年Beagle犬摄食W0868低谷蛋白大米后的相对血糖生成指数,并对比研究和定量评价W0868低谷蛋白大米对餐后血糖及胰岛素水平的影响,为低谷蛋白大米的应用及后续实验提供理论参考。方法:通过全自动生化分析仪检测餐后血糖浓度;通过酶联免疫吸附检测试剂盒测定餐后血清胰岛素含量。结果表明,与对照食物(五常大米)相比,W0868低谷蛋白大米对Beagle犬造成血糖浓度升高的总累积量更低,尤其是餐后1 h之后。此外,按照血糖生成指数的定义,根据基线校正后的0~120 min血浆葡萄糖曲线下面积,计算得到W0868低谷蛋白大米和对照食物相比的相对血糖生成指数的几何平均值为59.33%,90%置信区间为42.56%~82.72%。因此可以认为,以相同标准单次定量喂食Beagle犬,W0868低谷蛋白大米升高Beagle犬血糖的速率和程度比对照食物低40.67%。由此可见,W0868低谷蛋白大米可以降低Beagle犬餐后血糖生成指数,平缓餐后血糖浓度波动。

Abstract: The objective of this study was to evaluate the relative glycemic index of low gluten rice (W0868) in healthy adult Beagle dogs and to comparatively and quantitatively evaluate the effect of W0868 on postprandial blood glucose and insulin levels, so as to provide a theoretical reference for the application and further studies of low gluten rice. Methods: The postprandial blood glucose concentration was measured by an automatic biochemical analyzer, and the postprandial insulin content of serum was measured by an enzyme-linked immunosorbent assay kit. The results showed that the total cumulative effect of W0868 on increasing the blood glucose level of Beagle dogs was lower than that of the control diet, especially at postprandial 1 hour. In addition, according to the definition of glycemic index, the geometric mean value of relative glycemic index of W0868 compared with the control diet was calculated as 59.33% with a 90% confidence interval of 42.56%–82.72% using the area under the plasma glucose curve for 0–120 min after baseline correction. Therefore, it can be considered that the rate and degree of increase in blood glucose of the animals fed with W0868 was 40.67% lower than that with the control diet under the same standard single ration feeding regimen. Therefore, the postprandial glycemic index of W0868 is low in Beagle dogs and it can result in smooth postprandial glycemic fluctuations.
