摘　　要：目的对天津某武警部队每日膳食摄入量进行调查,并通过两种方法对食物的营养成分进行分析比较,了解实际膳食营养素摄入状况。方法膳食调查采用称重法并参照《中国食物成分表2002》计算各食物营养素摄入量;营养成分分析采用双份饭法收集食物样品,应用化学分析法测定食物中各种营养素含量。结果分析测定的膳食中主要营养素(蛋白质、脂肪及碳水化合物)、矿物质(Na、K、Mg、Ca、Zn、Cu及Se)和维生素(β-胡萝卜素、维生素E、硫胺素、核黄素、维生素C、烟酸、维生素B6及维生素A)的摄入量与膳食调查计算值相比较均偏低。结论两种方法的差异性最终表现为食物的实际测定值小于膳食调查计算值,有必要改善食物的储运加工方式,以达到合理营养,提高官兵健康水平。Objective To assess the differences in nutrient composition by chemical analysis method and weighing method,A corps of armed police forces daily dietary nutrient intakes were investigated in Tianjin,to understand the status of the actual intakes of dietary nutrient.Methods A dietary survey was performed using the weighing method and with ref-erence to China food composition database in 2002.The intake of each nutrient was calculated through chemical analysis;Nutritional analysis was used in the collection of duplicate food portions during the dietary survey.Results For most of the main dietary nutrients（protein,fat and carbohydrates）,minerals （Na,K,Mg,Ca,Zn,Cu and Se）and vitamins （β-car-otene,vitamin E,thiamine,riboflavin,vitamin C,niacin,and vitamin A）,the calculated values of intakes were found to exceed those obtained via chemical analysis.Conclusion Differences of the two methods of dietary survey were ultimately due to the analysed values were below the calculated ones.So it is necessary to improve methods of food storage and trans-portation in order to obtain adequate nutrition and to improve the health of troops.
