A comprehensive database of declared high-intensity sweeteners in Brazilian commercial products and updated exposure assessment

Abstract

Government regulatory actions and public policies to reduce sugar consumption were recently implemented in Brazil. To evaluate their potential impact on the supply of products containing high-intensity sweeteners (HIS) and on dietary exposure to these substances, this study aimed to create a comprehensive database on HIS declared in Brazilian commercial products and estimate their intake through consumption of these products. The occurrence of HIS was evaluated through labeling information of 1869 commercial products available in the Brazilian market, collected between January 2021 and August 2021, and the daily intake was estimated for eight HIS (acesulfame K, advantame, aspartame, cyclamate, steviol glycosides, neotame, saccharin and sucralose) using a deterministic approach by multiplying the maximum permitted levels of HIS in foods and beverages by the consumption data of these products. The consumption data were obtained from the report of Household Budget Survey (POF/IBGE), conducted from 2017 to 2018 through a 24-hour dietary recall applied to 46,164 individuals aged 10 years and over, which included only average data (i.e. average consumption for the general population or subgroups). The most frequent HIS in the investigated products were sucralose (26.8 %; n = 938) and acesulfame K (21.7 %; n = 759), and although the combination of sweeteners is a common practice in the food industry, there was a predominance of only one substance in the investigated products (46.7 %; n = 873). The estimated intake of HIS for average consumers was below the Acceptable Daily Intake (ADI) and does not suggest a toxicological concern. A similar scenario was observed for high consumers, except for cyclamate and steviol glycosides, which corresponded to 144 % and 131 % of their respective ADIs in the general population. To our knowledge, this is the most comprehensive database on HIS in Brazil and the most recent exposure assessment performed nationally.
