Yuka and Que Choisir Ensemble alert consumers to additive washing

Consumer advocacy groups Que Choisir Ensemble and the Yuka application have released a joint investigation into a marketing practice they call “additive washing.” The report, published on November 3, 2026, examines 20 ultra-processed food products that use reassuring labels such as “no preservatives” or “no artificial colors” to mask the presence of other potentially harmful additives.

While the claims on the packaging are often technically accurate, the organizations argue they exploit a cognitive bias known as the “halo effect,” where one positive attribute misleads consumers about the overall healthfulness of a product. The investigation found that 19 out of the 20 analyzed products contained at least one additive classified as a high risk. Some products, such as Haribo Miami Pik candies, were found to contain up to eight different additives despite prominent “no artificial color” claims.

Brands identified in the study include Ker Cadélac, Old El Paso, Haribo, Findus, Knorr, and Yoplait. The researchers used risk classifications based on data from the EFSA, FAO, WHO, and CIRC. Specific concerns were raised regarding polyphosphates, which are associated with cardiovascular and renal risks according to Anses.
