Postprandial hyperglycemia and insulin secretion depend on many factors, such as food composition, carbohydrate type and processing. The purpose of this study was to evaluate the effects of foods differing in composition in nonobese clinically normal dogs. These dogs were offered in a single meal one of the four foods. Blood samples were collected before feeding and during the 180 min after the meal. Plasma glucose and insulin concentrations were determined. The integrated areas under the postprandial glucose and insulin response curves were calculated. Times to response peaks, maximum plasma insulin elevation, area under the insulin response curve and the insulinemic index differed between dog foods. Crude fiber content had no significant effect. The time to glucose peak was higher and the time to insulin peak lower with the food highest in protein and ether extract content. The time to glucose peak was correlated to protein, fat and nitrogen-free extract content of foods, whereas the time to insulin peak and the area under the insulin curve were correlated to protein and nitrogen-free extract.
餐后高血糖和胰岛素分泌取决于许多因素，如食物成分、碳水化合物类型和加工方式。本研究的目的是评估成分不同的食物对非肥胖临床正常犬的影响。这些犬被单次喂食四种食物中的一种。在喂食前和餐后180分钟内采集血样。测定血浆葡萄糖和胰岛素浓度。计算餐后葡萄糖和胰岛素反应曲线下的积分面积。不同狗粮之间的反应峰值时间、最大血浆胰岛素升高值、胰岛素反应曲线下面积和胰岛素血症指数有所不同。粗纤维含量没有显著影响。蛋白质和乙醚提取物含量最高的食物，其葡萄糖峰值时间较长，胰岛素峰值时间较短。葡萄糖峰值时间与食物中的蛋白质、脂肪和无氮提取物含量相关，而胰岛素峰值时间和胰岛素曲线下面积与蛋白质和无氮提取物相关。
