Wheat is preferable over rice due to its lower glycemic index (GI). It is not known if the same is true when these staples are a part of mixed meals, hence we compared the Glycemic responses of wheat/rice containing mixed meals.
Glycemic responses of 2 mixed meals were compared with reference meal (glucose) where each was designed to provide a total of 50 g of available carbohydrate (AvCHO), in 10 healthy adult volunteers as per recent recommendations. Test meal 1 comprised of a pulse preparation (green gram ), a vegetable (ladies' finger), and 2 wheat . In test meal 2 these wheat were replaced by cooked rice supplying an equal amount of AvCHO. After an overnight fast of 10- 14 h, capillary blood glucose estimations were done subsequent to eating each test meal or glucose. GI of test meals was calculated by comparing their area under curve (AUCs) with AUC for glucose. GI of test meals were compared using unpaired test.
The study sample comprised of 7 males and 3 females with mean age 30.9 ± 5.1y. The GI of test meal 1 (85.5 ± 11.8%) and test meal 2 (83.6 ± 11.4%) was not significantly different ( = 0.7095).
The present study found no differences in glycemic index of wheat and rice based mixed meals with equivalent AvCHO content of the staple.
由于小麦的血糖生成指数（GI）较低，因此比大米更可取。当这些主食作为混合餐的一部分时情况是否如此尚不清楚，因此我们比较了含小麦/大米混合餐的血糖反应。
按照最新建议，在10名健康成年志愿者中比较了2种混合餐与参考餐（葡萄糖）的血糖反应，每种餐均设计为提供总共50克可利用碳水化合物（AvCHO）。测试餐1由豆类制品（绿豆）、一种蔬菜（秋葵）和2份小麦组成。在测试餐2中，这些小麦被提供等量AvCHO的煮熟大米所替代。在禁食10 - 14小时后，进食每种测试餐或葡萄糖后进行毛细血管血糖测定。通过将测试餐的曲线下面积（AUC）与葡萄糖的AUC进行比较来计算测试餐的GI。使用非配对t检验比较测试餐的GI。
研究样本包括7名男性和3名女性，平均年龄30.9±5.1岁。测试餐1（85.5±11.8%）和测试餐2（83.6±11.4%）的GI没有显著差异（P = 0.7095）。
本研究发现，主食AvCHO含量相当的以小麦和大米为基础的混合餐的血糖生成指数没有差异。
