53例糖尿病患者膳食中膳食纤维的摄入量调查

Investigation of dietary fiber intakes and varies in 53 patients with diabetes

目的调查糖尿患者总膳食纤维、可溶及不可溶性膳食纤维的摄入量,为糖尿患者膳食纤维营养状况的研究提供重要基础数据.方法通过不同实验室间的比对研究建立膳食纤维酶重量分析方法.采用称重法和食物计量图片法登记53例糖尿患者连续3 d每餐的食物摄入种类和重量, 利用酶重量法建立的食物中膳食纤维数据库计算膳食纤维摄入的数量和种类.结果 3个实验室测定膳食纤维数据的相对标准偏差在2.63%～9.67%之间.调查对象蔬菜类食物摄入量最多,是膳食纤维的主要来源.调查对象总膳食纤维摄入量为(26.5±9.8) g/d,不可溶性膳食纤维摄入量为(14.6±5.8) g/d,可溶性膳食纤维摄入量为(10.4±4.4) g/d.结论本次调查对象的总膳食纤维日摄入量处于美国糖尿病协会推荐摄入量范围内.

Objective To investigate the intakes of total dietary fiber （TDF）, soluble dietary fiber （SDF） and insoluble dietary fiber （IDF） in Subjects With Type 2 Diabetes so as to provide the base for making the adequate intakes of dietary fiber. Methods The enzymatic-gravimetric methods for dietary fiber were established on basis of a collaborative study. Dietary intake was measured by means of 3-day food records through weighting and using food pictures. TDF, SDF and IDF were analyzed by enzymatic-gravimetric methods. Results The reproducibility relative standard deviations for DF ranged from 2.63% to 9.67%. Vegetable foods were the mainly sources of DF. The total dietary intakes, insoluble and soluble fibers were 26.5±9.8, 14.6±5.8, 10.4±4.4 （g/d） respectively. Conclusion The dietary fiber intake of the diabetes remains in the range of intakes recommended by American Diabetes Association.
