Resumo: | OBJECTIVE: To evaluate the performance and perception of five models of front-of-package nutrition labeling (FOPNL) among Brazilian consumers. METHODS: Cross-sectional study, which applied an online questionnaire to 2,400 individuals, allocated randomly into six study groups: a control group and five others exposed to FOPNL (octagon, triangle, circle, magnifier and traffic light), applied to nine products. We evaluated the understanding of nutritional content, the perception of healthiness, the purchase intention and the perception of Brazilian consumers on the models. RESULTS: All FOPNL models increased the understanding of the nutritional content and reduced the perception of healthiness and purchase intention, when compared with the control group (41.3%). FOPNL warning models — octagon (62.4%), triangle (61.9%) and circle (61.8%) — performed significantly better than the traffic light (55.0%) regarding the understanding of the nutritional content. The performance of the magnifier (59.5%) was similar to the other four tested models, including the traffic light (55.0%), for understanding nutritional content. The individual analysis of the products suggests a better performance of warnings in relation to the magnifier and the traffic light for the perception of healthiness and purchase intention. Consumers were favorable to the presence of FOPNL, perceiving it as reliable to increase the understanding to nutritional information. CONCLUSION: FOPNL must be implemented on food labels in Brazil, considering that it increases the nutritional understanding, reduces the perception of healthiness and the purchase intention of products with critical nutrients. Warnings showed a better performance when compared with other models. |

MÉTODOS: Estudo transversal, com aplicação de questionário online a 2.400 indivíduos, alocados de forma aleatória em seis grupos de estudo, sendo um controle e cinco expostos a modelos de RNF (octógono, triângulo, círculo, lupa e semáforo), aplicados a nove alimentos. Foi avaliado o entendimento do conteúdo nutricional, a percepção de saudabilidade, a intenção de compra e a percepção dos consumidores brasileiros sobre os modelos. RESULTADOS: Todos os modelos de RNF aumentaram o entendimento do conteúdo nutricional e reduziram a percepção de saudabilidade e a intenção de compra, quando comparados ao grupo controle (41,3%). Os modelos de RNF de advertência - octógono (62,4%), triângulo (61,9%) e círculo (61,8%) - apresentaram desempenho significativamente superior ao semáforo (55,0%) quanto ao entendimento do conteúdo nutricional. O desempenho do modelo da lupa (59,5%) não diferiu dos outros quatro modelos testados, inclusive do semáforo (55,0%), para o entendimento do conteúdo nutricional. A análise individual dos alimentos sugere melhor desempenho das advertências em relação à lupa e ao semáforo para a percepção de saudabilidade e a intenção de compra. Os consumidores manifestam-se favoráveis à presença da RNF, percebendo-a como confiável para aumentar o entendimento das informações nutricionais. CONCLUSÃO: A RNF deve ser implementada nos rótulos dos alimentos no Brasil, considerando que aumenta o entendimento nutricional, reduz a percepção de saudabilidade e a intenção de compra de alimentos com nutrientes críticos. As advertências apresentaram melhor desempenho quando comparadas aos demais modelos.Universidade de São Paulo.
