The Nutri-Score in France and beyond: development, validation and transfer

Abstract

Abstract The Nutri-Score is a summary graded front-of-pack nutritional label, providing a synthetic information to consumers on the overall nutritional quality of a food product, based on its composition in several key unfavourable (energy, saturates, sugars, salt) and favourable (proteins, fibers, fruit, vegetables, nuts, legumes and certain vegetable oils (olive, rapeseed and nuts)). The Nutri-Score was developed by a team of independent scientists, and initially proposed in France in 2014. Following intense opposition by industry and considerable arguments, a 2-yearlong debate, the Nutri-Score was selected to be the official French front-of-pack nutrition label. In parallel, more than 40 publications in peer-reviewed journals investigated its validity on multiple dimensions, further supporting its implementation. Following the implementation of the Nutri-Score, consumer groups' pressure and a growing interest from the public pushed manufacturers to adopt the label, with more than 300 pledges of adoption from industry in 2020. After France, neighbouring countries (Belgium, Spain, Switzerland, Germany and the Netherlands) have now also adopted the scheme, prompting new challenges for development at a larger scale. The implementation of the system in France was made possible by strong public support for such a measure - relayed by consumer groups and disseminated in the media and a strong political will from the Health ministry to put together a validated and helpful system, which finally prevailed upon economic interests. Sustained support from consumers in particular helped turn the tide from a relatively low engagement of stakeholders towards the acknowledgement of the Nutri-Score as a standard for front-of-pack labelling in France and several EU countries. The Nutri-Score is an example of a public health measure informed by scientific evidence that may have a clear impact on the nutritional quality of diets in the population.
