Objectives. To identify the front-of-package scheme—Multiple Traffic Light (MTL), Nutri-Score (NS), and black octagon Warning System (WS)—most effective in reducing purchase intention and perceived product health- fulness of drinking yogurts, cookies and cheese spreads, and to assess the joint influence of nutrient claims on the effects. Methods. Randomized-controlled experiment. A within-subjects factorial design was used to evaluate the influence of three independent factors on perceived product healthfulness and purchase intention. A total of 704 adults in Argentina were shown three mock-up products and asked to indicate which product they would buy choosing between pairs of products from different categories and to rate product healthfulness on a 7-point Likert scale. Results. The WS was the most effective in reducing purchase intention in drinking yogurts (OR:0.16, 95%CI: 0.09;0.28), cookies (OR:0.10, 95%CI: 0.05;0.18) and cheese spreads (OR:0.10, 95%CI: 0.05;0.18), and the perception of healthfulness (WS Mean score 3,63 vs No label 4,24, p<0.001), regardless of the participants’ gender, age, and level of education. NS was inefficacious in reducing product healthfulness perception, while MTL had significantly increased how healthful the product was perceived (p<0.001). Nutrient claims increased purchase intention and perception of healthfulness, thus reducing the effectiveness of front-of-package labels (p<0.001). Conclusions. In line with growing evidence, our findings support that WS perform better than NS and MTL in reducing purchase intention and healthfulness perception of products with excessive amounts of critical nutrients associated with the greatest burden of diseases. Front-of-package WS are expected to facilitate the population in Argentina to make healthier decisions.

Article – Evaluation of food supplement labels referred to the current Brazilian legislation
According to Brazilian National Health Surveillance Agency, a food supplement is a product used orally and available in various pharmaceutical compounds to complement the diet of the healthy population. In this context, nutritional labeling is essential to inform and ensure consumers’ quality of consumption of these products. This work aimed to evaluate the compliance labels regarding the national food supplements marketed online against the Brazilian legislation in which the Resolution 243 entered into force on July 26, 2018. Data collection was carried out through surveys in online stores of national food supplements sold in Campo Grande – in the Mato Grosso do Sul state (MS) from August 2020 to January 2021. Three questionnaires were applied in a checklist to identify and analyze the food supplement labels, which were divided into 6 categories: carbohydrates; proteins; isolated amino acids; creatine; caffeine; and vitamins and minerals. A total of 130 labels were evaluated, being distributed in the categories, obtaining 16.2% of carbohydrates, 23.8% of proteins, 21.5% of isolated amino acids, 10.8% of creatine, 11.5% of caffeine and 16.2% of vitamins and minerals. It was found that 61.5% of food supplements did not have the designation “Food Supplement”, in addition to its pharmaceutical form. Most of the labels evaluated were inadequate in terms of designation and mandatory warnings required by current legislation, and further studies on the subject were recommended.
Article – From the most to the least flexible nutritional profile: Classification of foods marketed in Brazil according to the Brazilian and Mexican models
Nutrient profiling is the science of classifying or ranking foods according to their nutritional composition, for reasons related to disease prevention and health promotion. To be effective, policies such as front-of-pack nutrition labeling (FoPNL) must have an adequate nutritional profile model, since it will determine which products will be eligible to receive a FoPNL. This study aimed to determine the percentage of packaged food and drink products available in Brazil that would be subject to FoPNL under two different legislations: Brazilian and Mexican. This is a cross-sectional study in which we collected information on food products (photos of the ingredients list, the front label, the barcode, and the nutrition facts table) from one of the largest stores of a supermarket chain in the city of Belo Horizonte-MG, Brazil, from March to May 2021 (~6 months after the publication of the Brazilian legislation about FoPNL and a year and a half before the legislation came into force). The products were classified in relation to the BNPM (added sugars, saturated fats, and sodium) and the MNPM (energy, free sugars, saturated fats, trans fats, sodium, non-sugar sweeteners, and caffeine).
Article – Influence of nutrition claims on different models of front-of-package nutritional labeling in supposedly healthy foods: Impact on the understanding of nutritional information, healthfulness perception, and purchase intention of Brazilian consumers
Nutrition claims are positive information about foods, which are widely used as a marketing strategy on labels. On the contrary, front-of-package nutritional labeling (FoPNL) aims to make it easier for consumers to understand the nutritional composition of foods and favor healthy food choices. However, the concomitant presence of nutrition claims and FoPNL may hinder the understanding, judgment, and choices of consumers at the moment of purchase. Therefore, the objective of this study was to evaluate the influence of nutrition claims on the efficacy of FoPNL models in the understanding of nutritional information, healthfulness perception, and purchase intention of Brazilian consumers. It was an experimental cross-sectional study carried out using an online questionnaire, with a total of 720 participants randomly divided into four FoPNL conditions: control, octagon, triangle, and magnifying glass. Each participant looked at 12 food packages, which were produced following the factorial design: (i) food category (cereal bar, whole grain cookies, and snacks); (ii) product type (containing one critical nutrient × containing two critical nutrients); and (iii) nutrition claims (present × absent).
Article – CARICOM’S efforts to tackle unhealthy diets: A cautionary tale for Latin America
The Caribbean Community (CARICOM) is currently burdened with high rates of non-communicable diseases (NCDs). Unhealthy diets are a major factor driving the region’s increased NCD rates. Since the 1990s, trade agreements have facilitated an influx of ultra-processed foods and sugary beverages into the region. These unhealthy commodities contain excess critical nutrients, which are closely linked to the top three NCDs risk factors in the Americas––high blood pressure, high blood sugar, and obesity. Mandating front-of-package warning labels (FOPWL) as part of a suite of public health interventions is a scientifically proven, human-rights compliant response to promoting healthier diets. FOPWL allows consumers to correctly, and quickly, identify pre-packaged food items that contain excess critical nutrients. Recognizing this, the CARICOM Regional Organization for Standards and Quality (CROSQ) revised its regional standards on the labeling of prepackaged foods to include FOPWL. However, the regional food and beverage industry worked assiduously to undermine CROSQ’s normative effort. In its quest, the industry exploited regional integration mechanisms, co-opted human rights and decolonization narratives to decenter public health and to seize autonomy over the FOPWL process. This paper analyses these strategies to serve as a cautionary tale for Latin America.
