PINEDA SOTO, Vannya Inés e DEL SOCORRO ESTRADA ORE, Ela Leila. Comparison of Three Types of Nutrition Label on Processed Food Packages in Peru, 2019. Perspect Nut Hum [online]. 2020, vol.22, n.1, pp.35-45. Epub 07-Out-2020. ISSN 0124-4108. https://doi.org/10.17533/udea.penh.v22n1a03.
Background:
A front-of-package nutrition label is a tool to help guide food selection towards a balanced and healthy diet.
Objective:
To understand the model of front-of-package nutrition label that most influences the understanding of calories and important nutrients in processed food products in adult participants in Lima, Peru.
Materials and Methods:
A quasi-experimental cross-sectional study with 384 participant adults of both sexes. Participants were distributed into four equal groups: no nutritional labeling; daily food guide; stop sign warning labeling; and daily food guide with a traffic light symbol. Each participant was given a questionnaire with 10 pictures of food packaging with the labeling model that corresponded to their randomized group, along with 10 additional questions, for a total of 20 possible questionnaire points. Points were given for correct answers to the 20 questions on the questionnaire, such as identifying correctly the number of calories and/or critical nutrients.
Results:
The highest total scores were for the daily food guide-traffic light group (12.1 ± 3.9) and daily food guide group (12.1 ± 3.7), with significant differences with respect to the other two groups. There were also differences in the scores of the identification of calories, saturated fat, and total fat; the highest values were for the same two groups indicated above (p <0.05). No differences in food labels were found for the identification of sugars or sodium.
Conclusions:
The daily food guide and daily food guide-traffic light models most influence the identification of calories and critical nutrients.
