摘要:目的：探讨低血糖指数膳食干预对2 型糖尿病病人营养治疗效果的影响。方法：选择住院2 型糖尿病病人109例,随机分为营养组56例和对照组53例。营养组由营养师根据患者情况提供低血糖指数营养治疗饮食,对照组则自行控制饮食。分别于住院第1天与3个月复查时对两组患者进行膳食调查及相关生化指标测定, 以观察营养治疗的效果。结果:采用干预措施后, 两组空腹血糖、餐后2 h血糖、糖化血红蛋白、血清胆固醇、甘油三酯等生化指标均降低, 但营养组与对照组相比效果更为明显(P＜005)；营养组的饮食结构更为合理。结论：低血糖指数膳食可有效控制2 型糖尿病病人的血糖、血脂水平,对促进患者康复有积极意义。Abstract: Objective: To observed the effect of nutrition therapy of low glycemic index foods on type 2 diabetic patients. Methods: A total of 109 subjects with the hospitalized diabetes were randomly allocated into two groups: The nutrition group(56 cases) were provided with weighed individual low glycemic index foods and the control group(53 cases) went on diet dominated by themselves. patients in both groups were investigated on meals, diabetic nutrition knowledge and were detected for correlative biochemical indices. Results：After the nutrition treatment, patients biochemical indices of fasting bloodglucose, blood sugar 2 hours after meal, hemoglobin of glycosylation, cholesterol and triglyceride in serum in both groups were significantly lower. Compared with the control group, the effect of the nutrition group was even better. The acknowledgement rate of nutrition knowledge on diabetes of the nutrition group improved significantly, and their meals were more scientifically arranged. Conclusion: The nutrition therapy of low glycemic index foods would be very helpful for type 2 diabetic patients to control their bloodsugar level and improve the nutritional state and outcome.
