BMJ子刊:中国人爱吃盐?五个国家加工肉类/鱼类产品中钠含量中国最高!少吃点火锅串串吧!

食品生产商在钠含量方面有很大的潜力,消费者也可以选择低盐食品,最重要的是,少吃点火锅串串烧烤!

高钠摄入是高血压的主要原因,增加了血管疾病、肾脏疾病及过早死亡的风险。2010年,全球平均钠摄入量约为4000毫克/天,是世界卫生组织建议的最大2000毫克/天的2倍。此前在中国进行的一项研究报告称,加工肉类和鱼类产品的平均钠含量分别为1029毫克/百克和1424毫克/百克,超过推荐每日钠摄入量的一半。

据为响应世卫组织到2025年将钠减少30%的目标,全世界陆续采取了各种减少钠的行动。减少钠摄入量已被确定为预防和控制高血压以及降低心血管死亡率的一种高成本效益的策略。本研究旨在比较五个国家加工肉类和鱼类产品中的钠含量,将有助于为此类产品中减少钠含量提供证据基础。

在2012年至2018年间,研究者利用FoodSwitch移动应用程序在5个国家的超市收集了26500种预包装产品、19601种肉类和6899种鱼类的产品标签上的钠含量。其中,中国为1898件,英国为885件,澳大利亚为5673件,南非为946件,美国为17098件。采用Kruskal-Wallis H和χ2检验,分别对五个国家的钠水平和达到2017年英国钠减少目标的比例进行了横断面比较。

结果显示,中国加工肉鱼产品组合钠含量最高(中位数为1050 mg/100 g, IQR: 774 1473),其次是美国、南非、澳大利亚,英国钠含量最低(432 mg/100 g, IQR: 236 786) (p < 0.001)。

加工肉和鱼制品的钠摄入量贡献值(%)

在加工肉类和鱼类产品中,钠含量最高的国家和最低的国家之间的差异是两倍到三倍。在这五个国家的某些特定食物子类中,以及每个国家的不同食物子类中,钠含量也存在很大差异。这表明食品生产商在钠含量方面有很大的潜力,消费者也可以选择低盐食品。
