International audience. Background: To help consumers to make healthier food choices, seven 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.Objective: The aim of the present 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.Methods: Three complementary French food composition databases were used to access extensive coverage of the food supply in France (N=46 752): the Oqali, Open Food Facts, 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 (e.g. consumption of fresh vegetables is promoted in FBDG, thus the Nutri-Score should rate favourably such products).Results: Out of all criteria, the initial algorithm met 63% (26/41) of them while the revised algorithm met 85% (35/41) of them. Improvements achieved by the updated version of the Nutri-Score in terms of alignment with the FBDG were particularly observed for high-fat products (i.e. fatty fish, nuts and seeds), sweet products (i.e. ice creams, sweet spreads), salty products (i.e. savoury snacks, salted nuts), for dairy beverages and for beverages with artificial sweeteners.Conclusions: The Nutri-Score's updated nutrient profiling system appeared to rate foods more consistently in regards to the French dietary guidelines and improved the currently existing system. The present work supports the implementation of the updated nutrient profiling system underlying Nutri-Score.
