Abstract
ABSTRACTOBJECTIVE: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.
Highlights
Também foram calculadas as médias de concordância, segundo a escala do tipo Likert, considerada como variável contínua, para as questões que avaliaram a percepção dos participantes em relação aos modelos de rotulagem nutricional frontal (RNF)
Em relação ao percentual médio de acertos dos participantes para o conjunto de nove alimentos, todos os modelos de RNF tiveram desempenho significativamente superior ao GC (Tabela 3)
O desempenho dos cinco modelos de RNF foi significativamente superior ao GC, reduzindo as médias de percepção de saudabilidade para o conjunto dos nove alimentos (Tabela 3)
Summary
Luisete Moraes BandeiraI , Jéssica PedrosoII , Natacha ToralII , Muriel Bauermann GubertI,II. Eles têm se mostrado mais eficientes em aumentar o entendimento, e consequentemente, reduzir a percepção de saudabilidade e a intenção de compra dos alimentos, quando comparados ao semáforo nutricional, que informa o baixo, médio e alto conteúdo dos nutrientes, ou ao Guideline Daily Amounts (GDA), que indica o percentual de nutriente presente no alimento em relação ao valor diário recomendado[6,7,8,9,10]. O objetivo deste estudo foi avaliar o desempenho de cinco modelos de rotulagem nutricional frontal (octógono, triângulo, círculo, lupa e semáforo) em aumentar o entendimento do conteúdo nutricional, reduzir a percepção de saudabilidade e a intenção de compra de alimentos, além de identificar a percepção de consumidores adultos brasileiros sobre estes modelos e a importância de fatores relacionados à escolha alimentar
