A white paper published by Julie Chapon, co-founder of the Yuka app, along with Serge Hercberg, creator of the Nutri-Score, and Mathilde Touvier, details the strategies used by food industry companies to challenge the Nutri-Score, a nutritional rating system developed in France. While the Nutri-Score is not mandatory in France, many multinational corporations have expressed dissatisfaction with their products receiving lower ratings and have sought to discredit the system. These companies often use legal actions and professional federations to push back against the adoption of the Nutri-Score, which aims to provide consumers with clear nutritional information. Chapon explains that since the launch of Yuka in 2017, her team has received numerous warnings from food and cosmetic companies unhappy with their product ratings. "Each time, these are companies that are not satisfied with their product's score. They ask us to remove or revise it," she says. The tactics used by these companies often involve intimidation or attempts to damage the reputation of Yuka and its creators. Yuka, which features a carrot-shaped logo, has become a key tool for consumers in France and around the world, with over 85 million downloads globally. The app allows users to scan product labels and receive detailed nutritional information, helping them make more informed choices. In April, the supermarket chain Intermarché announced it would display Nutri-Scores on all its private-label products. Recently, the company published a report in partnership with Hercberg and Touvier, which highlights the methods used by the food industry to undermine the Nutri-Score. The authors note that they all face similar pressures from the same powerful companies, which seek to delay the introduction of transparency tools. "They want to sow doubt," Chapon says. The report criticizes the covert actions of industry federations, such as the National Association of Food Industries (ANIA), which represents major brands like Lactalis, Haribo, and Ferrero without them directly facing the criticism. These powerful companies have significant financial resources, making it difficult for researchers and nutritionists to challenge their influence. For instance, the charcuterie industry, represented by ANIA, launched legal action against Yuka, claiming the app misrepresented nitrates as carcinogenic. Although Yuka initially lost the case, it eventually won on appeal, but the process cost the company 500,000 euros and three years of stress. The authors of the white paper also point out that some multinational companies created their own nutritional labels in 2017 to undermine the Nutri-Score, allowing them to present their products in a more favorable light. These tactics, however, were later abandoned due to public backlash and criticism. The authors hope that their report will raise awareness among the public and policymakers about the influence of the agro-industry and the need for greater transparency in food labeling.
