背景:为了帮助消费者做出更健康的食物选择,七个欧洲国家已经实施了包装前营养标签Nutri-Score。该算法在2022-2023年由Nutri-Score欧洲科学委员会更新,基于当前的科学知识。
目的:本研究的目的是调查国际上新开发的算法与法国基于食品的饮食指南(FBDG)的一致性,并比较初始和更新算法的各自性能。
方法:使用三个补充的法国食品成分数据库来访问法国食品供应的广泛覆盖(N=46752):Oqali,打开食物事实,Ciqual数据库。基于法国FBDG,定义了41个标准的列表,通过这些标准评估了法国FBDG和Nutri-Score之间的一致性(例如,FBDG促进了新鲜蔬菜的消费,因此,Nutri-Score应该对此类产品给予有利的评价)。
结果:在所有标准中,初始算法满足其中63%(26/41),而修订算法满足其中85%(35/41)。Nutri-Score的更新版本在与FBDG的一致性方面取得了改进,特别是在高脂肪产品(即脂肪鱼,坚果和种子),甜味产品(即冰淇淋,甜蜜的传播),咸产品(即咸味小吃,咸坚果),用于乳饮料和含有人造甜味剂的饮料。
结论:Nutri-Score的最新营养分析系统似乎可以根据法国的饮食指南对食物进行更一致的评价,并改进了现有的系统。本工作支持Nutri-Score基础的最新营养分析系统的实施。
To help consumers to make healthier food choices, 7 European countries have implemented the front-of-pack nutrition label Nutri-Score. The algorithm was updated in 2022-2023 by the Nutri-Score European scientific committee, based on the current scientific knowledge.
The aim of this study was to investigate the consistency of the newly internationally developed algorithm with the French food-based dietary
guidelines (FBDG) and compare the respective performances of the initial and updated algorithm.
Three complementary French food composition databases were used to access extensive coverage of the food supply in France (n = 46,752): the Oqali, OpenFoodFacts, and CIQUAL databases. Based on the French FBDG, a list of 41 criteria was defined by which the consistency between French FBDG and the Nutri-Score was assessed (eg, consumption of fresh vegetables is promoted in FBDG, thus the Nutri-Score should rate favorably such products).
Of all criteria, the initial algorithm met 63% (26/41) of them, whereas the revised algorithm met 85% (35/41) of them. Improvements achieved by the updated version of the Nutri-Score in
alignment with the FBDG were particularly observed for high-fat products (ie, fatty fish, nuts, and seeds), sweet products (ie, ice creams and sweet spreads), salty products (ie, savory snacks and salted nuts), dairy beverages, and beverages with artificial sweeteners.
The Nutri-Score\'s updated nutrient profiling system appears to rate foods more consistently regarding the French dietary
guidelines and improved the currently existing system. This work supports the implementation of the updated nutrient profiling system underlying Nutri-Score.
