The Nutri-Score is a color-coded front-of-pack nutrition label that classifies foods and beverages from A (higher nutritional quality) to E (lower nutritional quality). The NewTools-score is an adaptation of the Nutri-Score 2023-version, modified to better align with the Nordic Nutrition Recommendations. Validating nutrient profiling models in different countries is crucial for their reliability and effectiveness in promoting healthier food choices and combating non-communicable diseases.
This study aimed to assess the convergent validity of the Nutri-Score and the NewTools-score by evaluating their agreement with a reference standard based on rankings of foods' healthiness by Norwegian nutrition experts. Additionally, we examined the consistency among these experts in rating foods' healthiness representative of the Norwegian diet.
Between August and December 2023, 29 nutrition experts completed a web-based questionnaire, scoring 100 foods on a scale from 1 (less healthy) to 6 (very healthy) based on the Norwegian food-based dietary guidelines. Agreement among experts was evaluated using descriptive statistics and Cronbach's alpha. We calculated both Nutri-Score and NewTools-score for all 100 foods and assessed their agreement with the reference standard through cross-classification and score distribution analyses.
The nutrition experts exhibited high agreement in their healthiness ratings of foods representative of the Norwegian diet. The Nutri-Score 2023-version showed good agreement with the experts for most foods, although discrepancies were observed for wholegrain and refined grains, fat content in dairy products, certain fish products, and plant-based dairy and meat substitutes. The NewTools-score displayed overall better agreement with the reference standard for several foods and with fewer discrepancies.
Norwegian nutrition experts showed high agreement in rating the healthiness of foods representative of the Norwegian diet. While the Nutri-Score 2023-version aligned well with experts' ratings, the NewTools-score demonstrated better agreement than Nutri-Score in this Norwegian context, despite some remaining discrepancies.
营养评分是一种用颜色编码的包装正面营养标签，用于将食品和饮料从A（较高营养质量）到E（较低营养质量）进行分类。新工具评分是对2023年版营养评分的一种改编，经过修改以更好地符合北欧营养建议。在不同国家验证营养成分分析模型对于其在促进更健康的食物选择和对抗非传染性疾病方面的可靠性和有效性至关重要。
本研究旨在通过评估营养评分和新工具评分与基于挪威营养专家对食物健康程度排名的参考标准的一致性，来评估它们的收敛效度。此外，我们还检查了这些专家在对代表挪威饮食的食物健康程度进行评分时的一致性。
在2023年8月至12月期间，29名营养专家完成了一份基于网络的问卷，根据挪威基于食物的膳食指南，以1（不太健康）到6（非常健康）的等级对100种食物进行评分。使用描述性统计和克朗巴哈系数评估专家之间的一致性。我们计算了所有100种食物的营养评分和新工具评分，并通过交叉分类和分数分布分析评估它们与参考标准的一致性。
营养专家在对代表挪威饮食的食物健康程度评分方面表现出高度一致性。2023年版营养评分对大多数食物与专家的评分显示出良好的一致性，尽管在全谷物和精制谷物、乳制品中的脂肪含量、某些鱼类产品以及植物性乳制品和肉类替代品方面存在差异。新工具评分在几种食物上总体上与参考标准的一致性更好，差异更少。
挪威营养专家在对代表挪威饮食的食物健康程度进行评分方面表现出高度一致性。虽然2023年版营养评分与专家评分契合良好，但在挪威的这种情况下，新工具评分比营养评分显示出更好的一致性，尽管仍存在一些差异。
