This study investigated the presence of front-of-package labeling on food products in major retailers in Brazil after its implementation in 2022. Carried out from May to October 2023, we analyzed 2145 products of brands present in five Brazilian states. A total of 541 products presented front-of-package warnings. The categories varied in their adherence to front-of-package labeling, highlighting a prevalence of combined warnings, such as high in added sugar and high in saturated fat on sweet biscuits and chocolates. Sausages showed a high prevalence of high in sodium and high in saturated fat warnings. Beverages stood out as high in added sugar, while fats, dairy products, frozen preparations, seasonings, and sauces presented diversity in the warnings. Other products, such as panettone, showed a high presence of alerts. The study demonstrated the widespread presence of front-of-package labeling on ultra-processed products highly consumed by the Brazilian population. Considering the alarming presence of these foods in the Brazilian diet, it is concluded that front-of-package nutrition labeling is crucial to inform and raise awareness among consumers, allowing healthier choices and potentially contributing to a reduction in chronic diseases and the costs associated with treatment in the health system.
