Brazilian front-of-package nutrition labelling and food additives: an approach to identify ultra-processed food products.

Abstract

This study aimed to explore combinations of the Brazilian front-of-package nutrition labelling (FoPNL) (high in added sugar, saturated fat and sodium) and/or three specific food additives with cosmetic functions (colourings, flavourings and non-sugar sweeteners - NSS) in packaged foods and beverages marketed in Brazil. This approach intends to strengthen the identification of ultra-processed food products (UPFP) by consumers through the information available on their labels. A cross-sectional study was carried out using data from the list of ingredients and the nutrition facts panel on labels of processed foods and UPFP available in Brazilian supermarkets between April and July 2017, totalling 8,436 food items assessed, of which 84.0% were UPFP. Of the total, 62.7% of the UPFP would have the FoPNL and 65.1%, 37.9% and 12.9% had flavouring, colouring and NSS, respectively. Combining criteria for the FoPNL with any one of the three cosmetic additives analysed, 45.9% of the UPFP were identified, and when considering the presence of the FoPNL, flavouring, colouring or NSS, the identification increased to 89.9%. Results showed that the current FoPNL in Brazil does not facilitate the identification of UPFP. In this sense, labels that indicate the presence of food additives with cosmetic functions (which are UPFP markers) could be a public health strategy to reduce the consumption of UPFP. Currently, food labelling regulations in Brazil are not aligned with Brazilian Dietary Guidelines recommendations.
