The dietary pattern of the population has shifted in recent years as a result of cultural changes and modifications in food accessibility. In order to describe the changes in food and beverage consumption patterns in the last two decades in Argentina, the National Survey of Household Expenditure [Encuesta Nacional de Gastos de los Hogares] was analyzed for the periods 1996-1997, 2004-2005 and 2012-2013. The average apparent consumption of food and beverages in grams or milliliters of net weight per adult equivalent was estimated for each period. The variation in the amount of food and beverages available for consumption between 1996 and 2013 shows that the structure of the dietary pattern has changed, appearing to indicate shifts in the ways of buying, preparing and consuming foods related to greater convenience and accessibility and less time spent on food preparation.

Existe una creciente evidencia de la transición global en los sistemas alimentarios que afectan la disponibilidad, accesibilidad, asequibilidad y conveniencia de los alimentos altamente procesados. El objetivo de este trabajo fue evaluar el consumo aparente de energía, grasas saturadas, azúcares agregados y sodio según el grado de procesamiento de los alimentos en la Argentina entre 1996 y 2018, según el nivel de ingreso. Se trata de un estudio descriptivo y transversal, con datos de gastos de alimentos y bebidas e ingresos de la Encuesta Nacional de Gastos de los Hogares de 1996-1997, 2004-2005, 2012-2013 y 2017-2018, que incluye más de 20.000 hogares en cada período. Se calculó el consumo aparente diario de energía, grasas saturadas, azúcares agregados y sodio por adulto equivalente de: (1) alimentos mínimamente procesados; (2) ingredientes culinarios procesados; (3) alimentos procesados y (4) productos ultraprocesados, para cada periodo y según el quintil de ingresos per cápita del hogar. Fue utilizado análisis estadístico descriptivo. En energía y todos los nutrientes evaluados, se observa la reducción de la proporción proveniente de alimentos mínimamente procesados, ingredientes culinarios y alimentos procesados, y el aumento de productos ultraprocesados. Con una mayor contribución a partir de ultraprocesados, a medida que aumentan los ingresos del hogar, pero con diferencias que disminuyen a lo largo del tiempo. Dados los resultados, las estrategias futuras en Argentina deberían promover el consumo de alimentos mínimamente procesados y desalentar la disponibilidad y accesibilidad de alimentos ultraprocesados, con especial énfasis en los grupos más vulnerados.

Evidence on what people eat globally is limited in scope and rigour, especially as it relates to children and adolescents. This impairs target setting and investment in evidence-based actions to support healthy sustainable diets. Here we quantified global, regional and national dietary patterns among children and adults, by age group, sex, education and urbanicity, across 185 countries between 1990 and 2018, on the basis of data from the Global Dietary Database project. Our primary measure was the Alternative Healthy Eating Index, a validated score of diet quality; Dietary Approaches to Stop Hypertension and Mediterranean Diet Score patterns were secondarily assessed. Dietary quality is generally modest worldwide. In 2018, the mean global Alternative Healthy Eating Index score was 40.3, ranging from 0 (least healthy) to 100 (most healthy), with regional means ranging from 30.3 in Latin America and the Caribbean to 45.7 in South Asia. Scores among children versus adults were generally similar across regions, except in Central/Eastern Europe and Central Asia, high-income countries, and the Middle East and Northern Africa, where children had lower diet quality. Globally, diet quality scores were higher among women versus men, and more versus less educated individuals. Diet quality increased modestly between 1990 and 2018 globally and in all world regions except in South Asia and Sub-Saharan Africa, where it did not improve.

Objective: To assess the association between the consumption of ultra-processed foods (UPFs) and diet quality among preschool children and women of reproductive age from Argentina Design: Cross-sectional and nationally representative survey. The food items were classified according to the NOVA system. Consumption of fruits, vegetables, legumes, nuts, seeds, and whole grains was estimated, and the energy and nutrients related to non-communicable disease (NCD) intake. Linear regression was used to assess the associations. Setting: Argentina. Participants: children 2-5y (n=7,022), female adolescent 10-19y (n=2,165) and women 20-49y (n=4,414). Results: UPFs represented more than a quarter of total energy intake, 27% in children, 31% in female adolescents, and 26% in women. Across all age groups, the major contributors to UPFs consumption were cookies and pastries (≈6.0-7.0%), soft drinks (≈2.7-3.7%), candies (≈1.8-4.6%), and juices (≈1.3-1.7%). The consumption of fresh vegetables, fresh fruits, and legumes was negatively associated with UPFs consumption. A significant positive association was found between the dietary share of ultra-processed foods and the dietary content of NCD-promoting nutrients such as free sugars and total saturated and trans fats. In contrast, a significant negative association was found with the content of NCD-protective such as fiber and protein. Conclusions: UPFs were associated with lower consumption of healthy foods and higher intake of nutrients related to NCDs in children and women of reproductive age in Argentina. It is necessary to design food policies that simultaneously reduce the consumption of UPFs while promoting the intake of fresh and whole foods to improve the dietary quality.

Food and beverage marketing has been identified as one of the determinants of unhealthy food and beverage consumption in the child population. Objective. To determine the frequency and duration of food and beverage advertising in children's programming and the nutritional quality of advertised food and beverages. Methods. Descriptive, cross-sectional study. Children's cable and broadcast channel programming was recorded in two periods: over the week and on the weekend. The type, quantity, and duration of commercials were recorded. The nutritional quality of advertised food and beverages was analyzed. Results. A total of 402.3 hours of children's programming were recorded. In total, 3711 commercials were identified. Among these, 20.9% corresponded to food and beverages, i.e., an average of 1.9 ± 1.0 commercials per hour or equivalent to 0.68 ± 0.36 min/hour. Dairy products, candies, and fast-food meals were the most advertised food products. Only a third of advertised food and beverages (35.8%) were categorized as healthy as per the nutrient profiling system. Based on the traffic light labeling system, 50% of advertised food and beverages were high in sugar, 25% were high in saturated fat, and approximately 15% were high in sodium or fat. Conclusion. Food and beverage advertising accounted for 20% of television advertising time. The most advertised products were dairy products, followed by candies and sweet snacks, fast-food meals, and beverages. Two-thirds of advertised food and beverages were considered unhealthy.

El entorno y el nivel socioeconómico son determinantes del comportamiento alimentario porque inciden en la disponibilidad, la accesibilidad y las preferencias alimentarias. Con el objetivo de describir el consumo aparente de alimentos y la disponibilidad de energía y nutrientes de hogares urbanos y rurales de la Argentina, según su nivel de ingresos, se analizó la Encuesta Nacional de Gastos de los Hogares 2004-2005. Se calculó el consumo aparente promedio de alimentos y bebidas en gramos o mililitros de peso neto por adulto equivalente por día, de hogares urbanos y rurales, y según quintil de ingresos per cápita del hogar. El 7% fueron hogares rurales, y presentaron mayor proporción de familias con bajos ingresos respecto a los urbanos. Existe un patrón de consumo aparente de alimentos y bebidas distinto entre hogares rurales y urbanos de Argentina, y además existen diferencias entre los hogares según el nivel de ingresos en ambos entornos. Conocer los contrastes y su magnitud es de gran utilidad para buscar estrategias tendientes a mejorar la alimentación de la población.

Consumption of food and beverages with NNSs is usual among children and adolescents, mainly from beverages. Less than 1% of children are exposed to a consumption of cyclamate and saccharin higher than the ADI.
