Abstract

GALAN, Pilar et al. Assessment of the objective understanding of 5 models of Front-of-Package labels in argentine consumers: results from a comparative study. Diaeta [online]. 2019, vol.37, n.166, pp.20-30. ISSN 1852-7337.

Obesity and non-communicable diseases (NCDs) are on the increase in Argentina. Maintaining an unhealthy diet is considered one of the most important risk factors in the development of these diseases. Front-of-package labels (FOPLs) are a useful tool to guide the consumer about the nutritional quality of the products as well as making healthier choices when buying. The efficiency of the FOPLs depends on the ease with which the information they provide is correctly understood. The objective of this study was to evaluate the objective understanding of Argentine consumers regarding five FOPLs [Health Star Rating System (HSR), Multiple Traffic Lights (MTL), Nutri-Score, Reference Intakes (RI), Warning Symbols]. During 2018, 1001 Argentine participants were recruited and, through an online survey, they were asked to classify 3 products from three categories of food (pizza, sponge cake and breakfast cereals) according to their nutritional quality. After this activity, they were randomly assigned one of the five FOPLs and asked to re-classify the same foods, but this time with the labeling on the packaging. The change in the ability to correctly classify the products in the two tasks was evaluated using an ordinal logistic regression. For the three food categories, Nutri-Score showed a better performance, followed by MTL, HSR, Warning Symbols and RI. Nutri-Score emerged as the most efficient FOPL to transmit information on the nutritional quality of food for Argentine consumers.
