摘要
目的分析四川省农村市场预包装食品钠含量及来源,为制订减盐(钠)措施提供参考依据。方法在2014年7-8月间,采用简单随机抽样方法在四川省随机抽取4个市(县),在其某乡镇上随机抽取1个小型超市和1个便利店,对食品标签信息进行拍照,采集预包装食品钠含量、营养素参考值百分比(NRV%)及来源,并对食品进行分级;采集市售价格,并计算最小份价格。结果低、中、高钠含量的食品分别占42.2%(116/275)、23.6%(65/275)、34.2%(94/275);中、高钠含量食品主要是肉蛋海产品类、谷类、豆及豆制品类、蔬菜水果类、薯类,且最小份价格低于5元的食品多于5元及以上的食品。钠的来源有食用盐、酱油、谷氨酸钠等调味料和含钠添加剂。结论 2014年四川省农村较高钠含量预包装食品为儿童青少年构建了一个有购买力的较高钠食品环境,可能是儿童青少年患高血压的危险因素之一,应推动和引导食品企业减少食品中钠含量。
Objective To analyze the sodium content and sources of the prepackaged food in the rural areas of Sichuan Province so as to provide reference for developing measures to reduce salt（sodium） intake.Methods Four cities（counties） were selected in Sichuan Province by simple random sampling method from July to August,2014,and a small supermarket and a convenience store were randomly sampled in a town in each county.The food ingredients on the food labels were photographed.The sodium content and the percentage of nutrient reference value（NRV%） of the prepackaged food were collected,and then the food samples were graded according to the content of sodium.The market prices of the prepackaged food were collected,and the minimum serving prices（MSPs） were calculated.Results The proportions of the food samples with low-,medium-and high-sodium were 42.2%（116/275）,23.6%（65/275） and 34.2%（94/275） respectively.The food samples with medium-and high-sodium were mainly meat,eggs and seafood,cereals,bean and bean products,vegetables and fruits,and tubers.Moreover,the food samples with MSPs 5 Yuan were more than those with MSPs ≥ 5 Yuan.The sources of sodium were salt,soy sauce,monosodium glutamate and other seasonings,and sodium additives.Conclusions The prepackaged food with medium-and high-sodium contents establishes an affordable and high-sodium food environment for rural children and adolescents in Sichuan Province in 2014,which may be one of the risk factors for their hypertension.Therefore,it is necessary to promote and guide the food enterprises to reduce sodium content in prepackaged food.
