The quali-quantitative study, with a cross-sectional design and exploratory character, was carried out in Curitiba, Paraná, with adult students from a public institution. Through a self-answered questionnaire, the comprehension of pictograms with and without a label that represented the presence of gluten, milk, meat, and egg, the relevance of the information presented, and the preference of the place where the nutritional information was made available were evaluated. 131 consumers participated with an average age of 21.3 ± 2.6 years, 73.3% of whom were female. A good perception of the proposed pictograms was observed, and was better understood with labels, which represented “contains egg” and “contains meat”. Regarding the presence of milk, the bottle pictogram was the most accepted.
