目的:调查武警某部官兵不同任务状态时的膳食营养配比,以评价执勤官兵的营养摄入状况。方法:以武警某执勤队全体官兵作为调查对象,用称重法进行为期3天的膳食回顾调查,分别评估固定勤务日和临时勤务日官兵的膳食量及问题。结果:临时勤务日平均每例每天摄入热能14.2MJ,高于固定勤务日12.5MJ。食物结构调查显示,谷类、蔬菜、畜禽肉、蛋类和鱼虾类食物摄入量均未达到军标要求。在能量来源分布中,两种勤务日的能量主要来源于植物性食物,占总能量的79.0%和86.0%,蛋白质摄入量为军标的91.8%和87.7%,维生素A、硫胺素和核黄素摄入平均达标率分别为57.6%、63.6%和72.4%,维生素C、维生素E和矿物质摄入充足。结论:该部膳食结构相对合理,但仍有优化空间,应减少烹调油用量,适量增加粗粮、蔬菜和鱼虾类食品的摄入,改进蛋类烹饪手段。
Objective: To investigate the nutritional balance of officers and soldiers of a certain armed police during different missions to assess the nutritional intake of officers and soldiers on duty. Methods: Taking all the officers and men of a duty team of armed police as the investigation object, we conducted a three-day dietary recall survey by weighing method to assess the diet and problems of officers and soldiers on fixed service days and temporary service days respectively. Results: The average daily intake of temporary service daily intake of heat per day 14.2MJ, higher than the fixed service day 12.5MJ. Food structure survey shows that cereal, vegetables, poultry, eggs and fish and shrimp food intake did not meet the military standard requirements. In the energy source distribution, the energy of the two service days mainly came from plant foods, accounting for 79.0% and 86.0% of the total energy, and the protein intake was 91.8% and 87.7% of the military standard. Vitamin A, thiamine and nucleus The average compliance rate of flavonoids intake was 57.6%, 63.6% and 72.4% respectively, with adequate intake of vitamin C, vitamin E and minerals. Conclusion: The dietary structure of the Ministry is relatively reasonable, but there is still room for improvement. The amount of cooking oil should be reduced, the intake of coarse grains, vegetables and fish and shrimp should be modestly increased, and the means of cooking eggs should be improved.
