Book excerpt: Data from Brazil shows an increase in obesity and non-communicable diseases, which is related to the expansion of the participation of ultra-processed food products in diets and in the food environment, displacing fresh and minimally processed foods and meals prepared with them. One of the solutions to improve food environments requires the implementation of effective and adequate food labeling regulations, including front-of-package labeling. This policy tool has the potential to inform the consumers about the nutrients, ingredients, or any other component of public health concern contained in the products and facilitate healthier food choices.
