营养素度量法对于公共卫生措施的建立是一个强有力的工具,它旨在以营养素含量为依据对食物进行分级评价。英国食品标准局(FSA)的营养素度量法(FSA score)已在英国食物数据库中得以验证。但是这个模型是否适用于其它国家食物数据库则还未被评价。本研究旨在评价英国FSA score在法国食物成分数据库中的应用。来源于法国NutriNet-Sante研究的食物成分表的食品根据英国FSA score进行分类,FSA score是以英国通讯署(OfCom)的切点值(‘健康的’总分≤4的食品和总分≤1的饮料;‘不健康的’总分>4的食品和总分>1的饮料)以及分布切点值(五分位的食物,四分位的饮料)。也可根据法国PNNS(Pro-gramme National Nutrition Sante)推荐的食物组对所采用的食品进行分类。从NutriNet-Sante研究(n=4225)具有法国人群中典型的食物中抽取样品,并根据其相对消耗量称量食品。根据OfCom切点值的食物分类与法国PNNS的食物组分类一致:97.8%的水果和蔬菜,90.4%的谷物和薯类以及仅3.8%的含糖零食被认为是健康的食物。此外,FSA score的可变性对于在同一食物组中子分类之间的区分,证实了使用FSA score作为多重分类体系的可行性,例如作为正面营养素标签的基础。英国FSA score在法国食物成分数据库中的应用更好的弥补了目前公共健康的推荐标准。
Nutrient metrics are a powerful tool for establishing public health measures that aim to grade food on a nutrient-content basis. The UK Food Standards Agency’s (FSA) Nutrient Metrics (FSA score) has been validated in the UK’s food database. However, the applicability of this model to other national food databases has not yet been evaluated. The purpose of this study was to evaluate the use of the UK FSA score in the French food ingredient database. Food products from the NutriNet-Sante study in France are classified according to the UK FSA score, which is based on the cut-off value of OfCom (’healthy’ score ≤ 4 with a total score ≤ 1 ; ’Unhealthy’ total score> 4 food and total score> 1 beverage) and distribution cut-off values (quintile food, quartile drink). The foods used may also be classified according to the food group recommended by Pro-gramme National Nutrition Sante, PNNS. Samples were taken from the NutriNet-Sante study (n = 4225), typical of the French population, and were weighed against their relative consumption. Food classification based on OfCom cutoff values is consistent with the food group classification of French PNNS: 97.8% fruits and vegetables, 90.4% cereals and potatoes, and only 3.8% sugary snacks are considered healthy foods. In addition, variability in the FSA score distinguishes between sub-categories within the same food group, confirming the feasibility of using the FSA score as a multi-classification system, for example, as a basis for positive nutrient labeling. The use of the UK FSA score in the French food ingredient database better complements the current public health recommendation.
