Scoping review of studies on food marketing in Latin America : summary of existing evidence and research gaps

Q3Q2OBJECTIVE: To document the evidence about marketing of ultra-processed foods and “non-alcoholic” beverages in Latin America. METHODS: We performed a structured search of quantitative and qualitative studies in PubMed, SciELO and LILACS, published between January 2000 and May 2017 and conducted in Latin America. We conducted a quality assessment following a standardized tool and a thematic analysis to identify key typologies of marketing across studies RESULTS: Out of 521 studies screened by title and abstract, we included 36 in this review; 27 of them analyzed television advertisement. Other marketing channels studied were food packaging, point of sale and outdoor advertisement. Studies found television advertises foods and beverages that are mostly ultraprocessed foods and have low nutritional value, particularly those promoted during children’s programming. We also observed children have a literal interpretation of images printed on food packaging, so this can be deceiving. Several studies also found proximity to unhealthy foods may increase their consumption. Finally, the thematic analysis identified the following typologies of food marketing: a) television advertisement, b) food packaging marketing, c) marketing strategies at points of sale and d) other marketing strategies. We found almost no advertisements for unprocessed or minimally processed foods such as fruits and vegetables. We did not find any studies on digital marketing conducted in the region. CONCLUSIONS: This review found that the main channel of food marketing was television advertising. This synthesis provides insights to the challenges unhealthy eating represents to the public health of Latin America and identifies knowledge gaps to guide future research.https://orcid.org/0000-0002-7343-8260https://orcid.org/0000-0003-1834-3012Revista Nacional - Indexad

Reformulation of packaged foods and beverages in the Colombian food supply

Q1Q1Public discussion, advocacy, and legislative consideration of policies aimed at reducing consumption of processed foods, such as sugar-sweetened beverage (SSB) taxes and mandatory front-of-package (FOP) warning labels, may stimulate product reformulation as a strategy to prevent regulation. In Colombia, there have been major legislative pushes for SSB taxes and FOP labels, although neither has passed to date. In light of the ongoing policy debate and successful implementation of similar policies in Peru and Chile, we explored manufacturer reformulation in the Colombian food supply. We compared the quantities of nutrients of concern (including sugar, sodium, and saturated fat) from the nutrition facts panels of the same 102 packaged foods and 36 beverages from the top-selling brands in Colombia between 2016 and 2018. Our analyses showed a substantial decrease in median sugar content of beverages, from 9.2 g per 100 mL to 5.2 g per 100 mL, and an increase in the percentage of beverages containing non-nutritive sweeteners (NNS), from 33% to 64% (p = 0.003). No meaningful changes in the quantities of nutrients of concern among foods were observed. Our findings suggest little reformulation has occurred in Colombia in the absence of mandatory policies, except for the substitution of sugar with NNS among beverages.Revista Internacional - Indexad

Designing an effective front-of-package warning label for food and drinks high in added sugar, sodium, or saturated fat in Colombia : an online experiment

Q1Q1Policies to require warnings on the front of food and drinks high in nutrients of concern (e.g., added sugar, sodium, or saturated fat) are becoming increasingly common as an obesity prevention strategy. Colombia, a country with growing prevalence of obesity, is considering implementing a similar policy. The objective of this study was to assess perceptions and reactions to different warning designs. We conducted a randomized experiment in an online panel of adults age > 18y (n = 1997). Participants were randomized to view one of four labels: a control label (barcode), an octagon warning, a circle warning, and a triangle warning. Participants viewed their randomly assigned label on a series of products and answered questions (continuous outcomes ranged from 1–4). Compared to the control, all warnings led to higher perceived message effectiveness (increase in mean from 1.79 in the control to 2.59–2.65 in the warning conditions, p < 0.001), a higher percentage of participants who correctly identified products high in nutrients of concern (from 48% in the control condition to 84–89% in the warning conditions, p < 0.001), and reduced intentions to purchases these products (decrease in mean from 2.59 to 1.99–2.01 in the warning conditions, p < 0.001). Relative to the control, warnings performed similarly across education levels, suggesting this policy would be equitable in Colombia. Looking at differences by warning type, the pattern of results suggested that the octagon warnings performed best. After viewing all label types, 49% of participants selected the octagon warning as the one that most discouraged them from consuming products high in nutrients of concern, while 21% and 27% selected the circle and triangle warning. Colombian policymakers should consider the octagon warning as part of a front-of-package labeling policy to help consumers identify and reduce consumption of foods and drinks high in nutrients of concern.https://scholar.google.com/citations?user=XWHmJd0AAAAJ&hl=eshttps://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000154547Revista Nacional - Indexad

Impact of nutrient warning labels on choice of ultra-processed food and drinks high in sugar, sodium, and saturated fat in Colombia : a randomized controlled trial

Q2Q1Objective: This study assessed nutrient warnings’ impact on product selection and identification of food products high in nutrients of concern in Colombia. Methods: In an online experiment (October 2020), 8,061 Colombians were randomized to a nutrient warning, guideline daily amounts (GDA), Nutri-Score, or no-label condition. They viewed two fruit drinks labeled according to their condition, one high in sugar and one not, and completed selection tasks. Next, they assessed four products high in sugar, sodium, and/or saturated fat (“high in” product). Finally, they selected which label would most discourage them from consuming a “high in” product. Results: The nutrient warning performed better on most outcomes. Twenty percent of participants exposed to the nutrient warning would purchase the high-sugar fruit drink compared to GDA (24%, p<0.01), Nutri-Score (33%, p<0.001), and no label (29%, p<0.001). GDA performed slightly better than the nutrient warning in identifying the high-sugar fruit drink (91% vs 88%, p<0.001). The nutrient warning best helped participants correctly identify other “high in” products (75% vs. 23% no-label, 26% Nutri-Score, and 43% GDA, all p<0.001) and had the highest perceived message effectiveness (3.86 on 5-point scale vs. 2.97 GDA and 2.70 Nutri-Score, both p<0.001) and lowest likelihood of purchasing “high in” products (2.58 on 5-point scale vs. 3.23 GDA, 3.49 Nutri-Score, and 3.51 no label, all p<0.001). The nutrient warning most discouraged participants from wanting to consume “high in” products. Conclusions: Nutrient warnings are a promising policy to help consumers identify and discourage consumption of products high in nutrients of concern.https://orcid.org/0000-0003-1834-3012Revista Internacional - IndexadaA1N

Tabla de intercambios de alimentos para uso en pediatría

Introduction: Food exchange lists (FEL) are useful tools for nutritionists that allow them to quantify the intake of calories and nutrients and to make feeding plans in a practical way. Objective: To design a FEL to be used in pediatric population in order to ease the nutritionists’ work when treating children. Materials and methods: Cross-sectional descriptive study. The most frequently consumed foods were selected based on 24-hour reminders and a food composition database (FCDB). Food exchange sizes were determined taking into account the age group food portion sizes. After the food composition chemical analysis, the portion sizes to be used at home (e.g. spoon, teaspoon, cup, etc.) were determined and the FEL for pediatric use was designed and validated. Results: A total of 241 foods, distributed in 9 groups and 4 annexes, were included. A main nutrient was considered for each group and the portion size to be used at home was defined according to the characteristics of each food. There was consistency between the FEL for pediatric use and the FCDB regarding consumption assessment (ICC>0.81). Conclusion: It was possible to develop a reliable FEL for pediatric use that will allow nutritionists to assess feeding and design feeding plans for preschoolers and schoolchildren in a practical way.Introducción. Para el profesional en nutrición, las tablas de intercambios de alimentos (TIA) son una herramienta que permite cuantificar la ingesta de calorías y nutrientes y planear la alimentación de manera práctica. Objetivo. Diseñar una TIA para uso en pediatría que facilite la labor del nutricionista en esta población. Materiales y métodos. Estudio descriptivo transversal. La selección de los alimentos consumidos con mayor frecuencia se realizó de acuerdo con recordatorios de 24 horas y una tabla de composición de alimentos (TCA). Se determinaron los tamaños de intercambio de alimentos teniendo en cuenta las porciones del grupo etario. Después del análisis químico de los alimentos se determinaron las medidas caseras (p. ej. cucharada, cucharadita, taza, etc.) y se diseñó y se validó la TIA para uso en pediatría. Resultados. Se incluyeron 241 alimentos, los cuales se distribuyeron en 9 grupos y 4 anexos. Se tuvo en cuenta un nutriente principal para cada grupo y la medida casera se definió según las características de cada alimento. Se observó concordancia en la evaluación de consumo entre las TIA para uso en pediatría y la TCA (CCI>0.81). Conclusión. Se desarrolló una TIA para población pediátrica confiable que permitirá evaluar la alimentación y diseñar planes de alimentación en preescolares y escolares de manera práctica
