Abstract
OBJECTIVE: This study aimed to assess the frequency of non-sugar sweeteners (NSS) in Brazilian food products and beverages before the implementation of new nutritional labelling legislation. Specifically, we aimed to determine the eligibility of these products to contain NSS according to RDC no. 18/2008, which governed the use of NSS in Brazil during the study period. DESIGN: Data were collected from 3335 packaged foods and beverages available in one of Brazil's top ten supermarket chains, six months following the publication of front-of-package nutrition labelling (FoPNL) and 19 months before the legislation came into force. SETTING: The study was conducted in the city of Belo Horizonte, state of Minas Gerais, Brazil. RESULTS: Our analysis revealed that NSS were present in 12·5 % of the sampled products. Notably, high frequencies of NSS were observed in powder dessert mixes and soya drinks (100 %), gelatin preparations (88·1 %), chewing gum (87·1 %), tea (84·6 %) and carbonated beverages (71·4 %). Furthermore, we found that 82 % of products containing NSS made claims regarding sugar and calorie reduction, with 16·6 % of these claims being inconspicuous. Additionally, 14 % of products targeted controlled sugar intake diets, 0·5 % aimed at sugar-restricted diets and 4 % were ineligible for NSS use. Importantly, the declared NSS content adhered to Brazilian regulatory limits in beverages. CONCLUSIONS: While most products complied with regulatory standards, our findings highlight the presence of ineligible products and less prominent claims, which may complicate NSS identification for consumers. Continuous monitoring of NSS frequency, especially following the implementation of FoPNL, is essential for ensuring compliance with regulations and promoting informed consumer choices in Brazil.
