This study evaluated changes in the use of sweeteners over one decade and the relationship between sociodemographics, diet, and weight status with the type of sweetener. Data came from the Brazilian National Dietary Surveys of 2008-2009 and 2017-2018, including ≥10-year-old individuals (n=32,749; n=44,744, respectively, after excluding pregnant and lactating women). The use of table sugar, non-caloric sweeteners [NCS], both, or none was reported through a specific question. Food consumption was assessed using two non-consecutive food records (2008-2009) and 24-hour recalls (2017-2018). For the last survey, means of energy, macro and micronutrient intake, food groups’ contribution (%) to daily energy intake, and age- and energy-adjusted nutrient intake were estimated according to the type of sweetener used. Differences in means and proportions across the categories of sweeteners used were evaluated based on the 95% confidence intervals. All analyses were stratified by sex, and considered sample design and weights. Over ten years, the use of table sugar decreased by 8%, while the habit of not using any sweetener increased almost three times, and the use of NCS remained stable. Larger reductions in the use of table sugar were observed in the highest income level and among men. Regardless of sex, compared to NCS users, table sugar users had greater mean intake of energy, carbohydrates, and added sugar, and lower micronutrient intake means. Although table sugar is still the most used sweetener, the increased choice of “no sweetener” is noteworthy. in Brazil.
