Resumo
Food labels are poorly understood by most Brazilians, demonstrating an important reformulation requirement. Objective: This work aimed to compare the consumer's understanding of the traditional label versus a new food labeling proposal. Methods: a cross-sectional study carried out in 2016 in seven supermarkets in a Brazilian capital. Participants were all consumers aged 18 or over who were shopping at the time of data collection and went through the canning session. To evaluate the understanding of food labeling, the sample was divided into two groups: Group A observed the Current Label and Group P observed the Proposed Label. The participants answered a questionnaire with five questions related to the respective label analyzed and provided socioeconomic and health data. Student’s t and qui-square tests were used for comparison, with 5% significance level. Results: A total of 980 consumers were interviewed in seven supermarkets in a Brazilian capital, mean age of 38.2 ± 13.9 years, the majority female (57.1%), with high school degree (46.4%), family income between US$ 540 and US$1080 (33.4%), no diagnosis of chronic disease (84.8%) and Body Mass Index of 25.6 ± 4.7 kg/m². The label’s reading was affirmative for 54.1% of Group A and 93.3% of Group P. Nutrition facts understanding was satisfactory for 36.1% of Group A and 96.9% of Group P. When analyzing the current label, several participants gave incorrect answers regarding the sodium and sugar content of the product and this percentage was lower in the proposed label (p = 0.019 and p = 0.008, respectively). Because of the complex language, only 36.5% of the respondents reported that the current label helps purchase, as opposed to the proposed label, which percentage was 97.5%, with affirmations regarding greater didactics and easiness of comprehension. All responses had a significant difference when comparing groups (p<0.05) and the understanding of proposed label was statistically higher in comparison to current label (p=0.026). Conclusion: the consumers' understanding of the proposed label was significantly higher than the current label.
