摘　　要：目的研究在等量碳水化合物的前提下,通过添加膳食纤维改变膳食中碳水化合物组分,对膳食血糖生成指数的影响,以帮助糖尿病患者合理搭配食物。方法 12例健康成年人随机分为白粥组和白粥+膳食纤维组,分别在不连续的3日内测定口服相当于含有50g碳水化合物的白粥或白粥+膳食纤维及50g葡糖糖后引起的血糖反应,计算白粥和添加膳食纤维后的白粥的血糖指数。结果白粥的血糖指数为69.16±23.77,添加膳食纤维后白粥的血糖指数降为53.94±11.39。结论在等量碳水化合物的前提下,通过在膳食中添加膳食纤维,可有效降低膳食血糖指数,可能有利于糖尿病患者保持血糖平稳,提高患者饮食控制依从性。Objective To study the influence of diet adding dietary fiber by changing carbohydrate component on dietary glycemic index under the premise of the same amount of carbohydrates to help people with diabetes collocate food reasonably. Methods Twelve healthy adults were randomly divided into the white congee group and the white congee adding dietary fiber group. The reactions of blood glucose to oral administration of white congee or white congee adding dietary fiber（ contain 50g glucose） and 50g glucose at discontinuous three days were observed. The glycemic index of the white congee and the white congee adding dietary fiber were calculated. Results The glycemic index of the white congee group was 69. 16 ± 23.77, and that of the white congee adding dietary fiber group dropped to 53.94 ± 11.39. Conclusion On the premise of equal amounts of carbohydrates, diet adding dietary fiber can effectively reduce dietary glycemic index to help people with diabetes blood sugar steady and improve their diet adherence.
