RESUMO
ABSTRACT The second edition of the Dietary Guidelines for the Brazilian Population (DGBP) advises "eating regularly and carefully", "eating in appropriate environments," and "eating in company". Individuals may interpret these guidelines differently. We analyzed social representations of these recommendations to ascertain how such representations relate to the official DGBP advice. This cross-sectional, exploratory study was conducted with a selected sample of teachers, administrative technicians, and students (N= 24) from the Federal University of Grande Dourados, Brazil. We carried out an exploratory content analysis of the responses to semi-structured interviews on the topic. We identified seven themes that encompassed the social representations of "eating regularly and carefully": 1) paying attention to what you eat; 2) having several meals; 3) eating slowly; 4) having time to eat; 5) eating without distractions; 6) eating adequate amounts; and 7) ensuring a nutritional balance. Four themes emerged from the analysis of the social representations of "eating in appropriate environments": 1) a pleasant environment; 2) at the table; 3) without interferences; and 4) a clean environment. The following themes encompassed the social representations of "eating in company": 1) eating in company is good; 2) I prefer to eat alone; and 3) eating in company is inconsequential. Although participant representations align with DGBP recommendations in the three orientations, in general, they extend beyond them. Professionals and government organizations in Brazil or abroad could take into consideration these results in order to optimize this tool's potential for research and policy in nutrition and public health.
RESUMEN La segunda edición de la Guía Alimentaria para la Población Brasileña (DGBP) aconseja "comer con regularidad y atención", "comer en ambientes adecuados" y "comer en compañía". Las personas pueden interpretar estas pautas de manera diferente. Analizamos las representaciones sociales de estas recomendaciones para determinar cómo se relacionan con la postura oficial de la DGBP. Este estudio transversal y exploratorio se realizó con una muestra seleccionada de profesores, técnicos administrativos y estudiantes (N= 24) de la Universidad Federal de Grande Dourados, Brasil. Realizamos un análisis exploratorio de contenido de las respuestas a entrevistas semiestructuradas sobre el tema. Identificamos siete temas que abarcan las representaciones sociales de "comer con regularidad y atención": 1) prestar atención a lo que come; 2) tener varias comidas; 3) comer despacio; 4) tener tiempo para comer; 5) comer sin distracciones; 6) comer cantidades adecuadas; y 7) asegurar un equilibrio nutricional. Cuatro temas surgieron del análisis de las representaciones sociales de "comer en ambientes adecuados": 1) ambiente agradable; 2) en la mesa; 3) sin interferencias; y 4) medio ambiente limpio. Los siguientes temas engloban las representaciones sociales de "comer en compañía": 1) comer en compañía es bueno; 2) prefiero comer solo; y 3) comer en compañía es intrascendente. Aunque las representaciones de los participantes se alinean con las recomendaciones de la DGBP en las tres orientaciones, en general, se extienden más allá de ellas. Investigadores y organizaciones gubernamentales en Brasil y en el extranjero podrían tener en cuenta estos resultados para optimizar el potencial de esta herramienta para la investigación y las políticas en nutrición y salud pública.
RESUMO
Cross-sectional nutritional survey data collected in eight countries were used to estimate saturated fatty acid intakes. Our objective was to estimate the proportion of excessive saturated fatty acid intakes (>10 % of total energy intake) that could be avoided if ultra-processed food consumption was reduced to levels observed in the first quintile of each country. Secondary analysis was performed of 24 h dietary recall or food diary/record data collected by the most recently available nationally representative cross-sectional surveys carried out in Brazil (2008-9), Chile (2010), Colombia (2005), Mexico (2012), Australia (2011-12), the UK (2008-16), Canada (2015) and the US (2015-16). Population attributable fractions estimated the impact of reducing ultra-processed food consumption on excessive saturated fatty acid intakes (above 10 % of total energy intake) in each country. Significant relative reductions in the percentage of excessive saturated fatty acid intakes would be observed in all countries if ultra-processed food consumption was reduced to levels observed in the first quintile's consumption. The reductions in excessive intakes ranged from 10â 0 % (95 % CI 6â 2-13â 6 %) in Canada to 35â 0 % (95 % CI 28â 7-48â 0 %) in Mexico. In all eight studied countries, all presenting more than 30 % of intakes with excessive saturated fatty acids, lowering the dietary contribution of ultra-processed foods to attainable, context-specific levels was shown to be a potentially effective way to reduce the percentage of intakes with excessive saturated fatty acids, which may play an important role in the prevention of non-communicable diseases, particularly cardiovascular diseases.

ABSTRACT The NOVA classification categorizes foods according to the extent of industrial processing. NOVA has been used in dietary guidelines of some countries including Brazil and Uruguay. This article aimed to investigate knowledge and perceptions of a sample of Brazilian adults regarding NOVA. A qualitative study was conducted in Dourados city, Mato Grosso do Sul, Brazil. First, participants (N= 24) were asked to classify a series of 24 pictures of foods and beverages using NOVA, which define the four major food groups: unprocessed or minimally processed foods; processed culinary ingredients; processed foods; and ultra-processed foods. Next, participants were asked to explain their classification through semi-structured interviews. Data from the classification activity were analyzed using non-metric multidimensional scaling and interviews using exploratory content analysis and summative content analysis. Participants seemed to understand NOVA in terms of food processing, food production, and additives used. They easily identified unprocessed or minimally processed foods and ultra-processed foods; processed culinary ingredients and processed foods were harder to identify. Professionals, researchers and government organisations in Brazil or abroad could consider the results of this study in order to optimize this tool's potential for research and policy in nutrition and public health.
RESUMEN La clasificación NOVA ordena los alimentos según su grado de procesamiento industrial. NOVA ha sido utilizado en las guías alimentarias de algunos países incluyendo Brasil. Investigamos el conocimiento y las percepciones de un muestreo de adultos brasileños con respecto a NOVA. Se realizó una investigación cualitativa en la ciudad de Dourados, Mato Grosso do Sul, Brasil. Los participantes (N= 24) clasificaran 24 imágenes de alimentos y bebidas en los cuatro grupos de NOVA: alimentos sin procesar o mínimamente procesados; ingredientes culinarios procesados; alimentos procesados; y alimentos ultraprocesados. Luego, se les pidió que explicaran su clasificación a través de entrevistas semiestructuradas. Los datos de esa actividad se analizaron mediante escala multidimensional no métrica y las entrevistas mediante análisis de contenido exploratorio y análisis de contenido sumativo. Los participantes entienden la NOVA en términos de procesamiento y producción de alimentos, y uso de aditivos. Ellos identificaron fácilmente los alimentos sin procesar o mínimamente procesados y los alimentos ultraprocessados pero no los alimentos de los otros grupos. Investigadores y organizaciones gubernamentales en Brasil y en el extranjero podrían tener en cuenta estos resultados para optimizar el potencial de esta herramienta para la investigación y las políticas en nutrición y salud pública.
RESUMO
OBJECTIVE: To evaluate the consumption of ultra-processed food and drink products and its association with the nutrient profile of the Colombian diet in 2005. MATERIALS AND METHODS: Food consumption based on 24-hour dietary records from 38 643 men and women was classified into four NOVA groups according to the extent and purpose of food processing. RESULTS: Ultra-processed food and drink products represented 15.9% of the total energy daily intake, compared to 63.3% from minimally processed food, 15.8% from processed culinary ingredients, and 4.9% from processed food. Non-ultra-processed food items had a healthier nutritional profile compared to ultra-processed items in terms of contribution to total calories from protein, carbohydrates, total fat, saturated fat, free sugar, fiber and energy density. CONCLUSIONS: Ultra-processed food products have a less healthy nutrient profile than non-ultra-processed ones. An increase in the consumption of these foods must be prevented within Colombia.
OBJETIVO: Evaluar el consumo de alimentos y bebidas ultraprocesadas y su asociación con el perfil nutricional dentro de la Encuesta Nacional de Nutrición de 2005 en Colombia. MATERIAL Y MÉTODOS: El consumo de alimentos basados en registros alimentarios de 24 horas de 38 643 individuos se clasificó en cuatro grupos de NOVA. RESULTADOS: Los productos de alimentos y bebidas ultraprocesados representaron 15.9% de la ingesta diaria total de energía, en comparación con 63.3% de los alimentos mínimamente procesados, 15.8% de los ingredientes culinarios procesados y 4.9% de los procesados. Los alimentos mínimamente procesados tenían un perfil nutricional más saludable en comparación con los artículos ultraprocesados en términos de contribución a las calorías totales, de proteínas, carbohidratos, grasa total, grasa saturada, azúcar libre, densidad de fibra y densidad de energía. CONCLUSIONES: Los alimentos ultraprocesados tienen un perfil nutricional menos saludable que los alimentos no procesados.

The aim of this study is to have an exploratory insight on how a sample of Brazilian adults classify food, attempting to identify the main factors involved in this process, and to compare these classifications to the NOVA food classification of the 2014 Brazilian dietary guidelines. An exploratory and qualitative approach was conducted with a selected sample of teachers, administrative technicians, and students (Nâ¯=â¯24) from the Federal University of Grande Dourados, Brazil. First, using the pile sort method, participants were asked to freely classify 24 pictures of food (sourced from examples of the four food groups specified in NOVA) into food groups meaningful to them. Next, in semi-structured interviews, participants were asked to describe the food groups they created. The food groups created by participants were analyzed using non-metric multidimensional scaling followed by hierarchical cluster analysis, and the interviews were analyzed using content analysis. Participants had a mean age of 30 (±9.4) years. A total of 128 food groups were created by 24 participants (an average of five food groups per person); and a total of 55 non-mutually exclusive groups names were used by them to describe these food groups. Sixteen themes emerged from the content analysis. The most recurrent themes were food groups, nutrients, foods I consume, foods I do not consume, and food processing. Contrasting themes such as real food and junk foods, meals and ready-made foods, healthy foods and unhealthy foods were also noted. Six clusters emerged from the cluster analysis, each related to one or more themes. Overall, a striking similarity was observed between the ways the individuals classified food and the NOVA food classification.

The present commentary contains a clear and simple guide designed to identify ultra-processed foods. It responds to the growing interest in ultra-processed foods among policy makers, academic researchers, health professionals, journalists and consumers concerned to devise policies, investigate dietary patterns, advise people, prepare media coverage, and when buying food and checking labels in shops or at home. Ultra-processed foods are defined within the NOVA classification system, which groups foods according to the extent and purpose of industrial processing. Processes enabling the manufacture of ultra-processed foods include the fractioning of whole foods into substances, chemical modifications of these substances, assembly of unmodified and modified food substances, frequent use of cosmetic additives and sophisticated packaging. Processes and ingredients used to manufacture ultra-processed foods are designed to create highly profitable (low-cost ingredients, long shelf-life, emphatic branding), convenient (ready-to-consume), hyper-palatable products liable to displace all other NOVA food groups, notably unprocessed or minimally processed foods. A practical way to identify an ultra-processed product is to check to see if its list of ingredients contains at least one item characteristic of the NOVA ultra-processed food group, which is to say, either food substances never or rarely used in kitchens (such as high-fructose corn syrup, hydrogenated or interesterified oils, and hydrolysed proteins), or classes of additives designed to make the final product palatable or more appealing (such as flavours, flavour enhancers, colours, emulsifiers, emulsifying salts, sweeteners, thickeners, and anti-foaming, bulking, carbonating, foaming, gelling and glazing agents).

Given evident multiple threats to food systems and supplies, food security, human health and welfare, the living and physical world and the biosphere, the years 2016-2025 are now designated by the UN as the Decade of Nutrition, in support of the UN Sustainable Development Goals. For these initiatives to succeed, it is necessary to know which foods contribute to health and well-being, and which are unhealthy. The present commentary outlines the NOVA system of food classification based on the nature, extent and purpose of food processing. Evidence that NOVA effectively addresses the quality of diets and their impact on all forms of malnutrition, and also the sustainability of food systems, has now accumulated in a number of countries, as shown here. A singular feature of NOVA is its identification of ultra-processed food and drink products. These are not modified foods, but formulations mostly of cheap industrial sources of dietary energy and nutrients plus additives, using a series of processes (hence 'ultra-processed'). All together, they are energy-dense, high in unhealthy types of fat, refined starches, free sugars and salt, and poor sources of protein, dietary fibre and micronutrients. Ultra-processed products are made to be hyper-palatable and attractive, with long shelf-life, and able to be consumed anywhere, any time. Their formulation, presentation and marketing often promote overconsumption. Studies based on NOVA show that ultra-processed products now dominate the food supplies of various high-income countries and are increasingly pervasive in lower-middle- and upper-middle-income countries. The evidence so far shows that displacement of minimally processed foods and freshly prepared dishes and meals by ultra-processed products is associated with unhealthy dietary nutrient profiles and several diet-related non-communicable diseases. Ultra-processed products are also troublesome from social, cultural, economic, political and environmental points of view. We conclude that the ever-increasing production and consumption of these products is a world crisis, to be confronted, checked and reversed as part of the work of the UN Sustainable Development Goals and its Decade of Nutrition.
