In 2023, the algorithm underlying the Nutri-Score front-of-pack label was updated to better align with food-based dietary guidelines (FBDGs) across countries engaged in the system. On the basis of a comparison of FBDGs and literature reviews with the current Nutri-Score classification, modification scenarios were developed and tested in nutritional composition databases of branded products in four countries. The updated Nutri-Score nutrient profile model allows a better discrimination between products, in closer alignment with FBDGs, while the updated algorithm adopts a stricter approach for products that are high in components of concern (including non-nutritive sweeteners) and low in favourable dietary components. The updated Nutri-Score algorithm increases the alignment between the front-of-pack label system and FBDGs, strengthening its potential as a complementary public health tool in an international perspective.

2023 年，Nutri-Score 包装正面标签的算法得到更新，以更好地符合参与该系统的国家/地区的基于食品的膳食指南 (FBDG)。在将 FBDG 和文献综述与当前 Nutri-Score 分类进行比较的基础上，制定了修改方案，并在四个国家的品牌产品的营养成分数据库中进行了测试。更新后的 Nutri-Score 营养成分模型可以更好地区分产品，与 FBDG 更加一致，而更新后的算法对关注成分（包括非营养性甜味剂）含量高且有利饮食含量低的产品采用更严格的方法成分。更新后的 Nutri-Score 算法增强了包装正面标签系统与 FBDG 之间的一致性，增强了其作为国际视野中补充性公共卫生工具的潜力。
