- Resumen: Ultra-processed foods (UPFs) are increasingly present in children’s diets; however, little is known about how early feeding practices influence UPF consumption in childhood. We aimed to evaluate the association between infant feeding during the first 4 months of life (breastfeeding vs. infant formula) and UPF consumption in toddlers.},

- Resumen: Objetivos: Describir el uso de información del envase para selección de alimentos por personas adultas en Chile y verificar su asociación con variables sociodemográficas y con ser responsable de niños/as. Métodos: Estudio transversal basado en datos secundarios de la Encuesta Nacional de Salud (ENS) 2016-2017. Fueron incluidas las personas mayores de 18 años e identificadas las responsables de niños/as de entre 7 meses y 5 años. Se analizó el uso de ingredientes, información nutricional, sellos de advertencia, mensajes saludables, marca y precio en la decisión de compra de alimentos (SÍ: siempre, casi siempre, algunas veces; NO: rara vez, nunca). Las asociaciones fueron verificadas con modelos de regresión logística, ajustados por variables sociodemográficas. },

- Resumen: Latin America is distinguished by diverse regulatory frameworks and evolving dietary patterns, including the weakening of traditional diets and the increasing consumption of ultra-processed foods (UPFs). Predominantly produced by transnational corporations, UPFs rely heavily on food additives to achieve desirable sensory properties (e.g., flavor, color), ensure food safety, and extend shelf life. Over the past decade, research has increasingly shown that higher consumption of UPFs is associated with poor health outcomes, and food additives have emerged as a potential mechanism underlying this association. However, few studies have systematically analyzed the presence of food additives in the food supply. This study aimed to assess the distribution and patterns of food additives in packaged foods from five Latin American countries.

- Resumen: Background: Growing interest in the Nova food classification system surged among various stakeholders, driven primarily by compelling evidence linking the consumption of ultra-processed foods (UPFs) to negative health outcomes. This growing interest underscores the potential value of identifying clear markers to classify UPFs, particularly to support research and regulatory efforts.Objective: To propose replicable methods to identify UPFs, by testing the sensitivity and specificity of these methods using a large sample of packaged foods from the 2017 Brazilian Food Labels Database.

- Resumen: Increasing consumption of ultra-processed foods (UPF) has been identified as a risk factor for obesity and various diseases, primarily in adults. Nonetheless, research in children is limited, especially regarding longitudinal studies with metabolic outcomes. We aimed to evaluate the longitudinal association between consumption of UPF, adiposity, and metabolic indicators in Chilean preschool children.},

IF [JCR]: 6.590. Q1
-Resumen: Introduction: Increasing consumption of ultra-processed foods (UPF), defined by the NOVA classification, has been associated with obesity and other health outcomes. However, some authors have criticized the UPF definition because it is somewhat subjective. Most studies identify UPF using food descriptions; nevertheless, NOVA developers described a list of ingredients, including substances not commonly used for cooking and "cosmetic additives" that could be used to identify UPF. Assessing the impact of the use of different UPF definitions is particularly relevant with respect to children's diet, because several dietary policies target this age group. Thus, our study compared the frequency of UPF among foods and beverages and their share in the diet of Chilean preschoolers using three different methods of identifying UPF.},

-Resumen: Reductions on the sugars content of the food supply have been described after the initial implementation Chilean Labeling Law, but it is unclear if sugars were replaced by non-caloric sweeteners (NNS). We evaluated changes in the NNSs use in foods and beverages after the initial implementation of the labeling law. We used longitudinal data on packaged foods and beverages collected in six major supermarkets and three candy distributors in Santiago, Chile, in January-February 2015/2016 and in January-February 2017. We included in the analysis beverages, dairy-based beverages, yogurts, breakfast cereals, desserts and ice creams, candies and sweet confectioneries, and sweet spreads with a market share ≥1% of their food groups (n = 999). We compared the use of any NNS, the number of different NNSs used, and the combined use of NNSs and ingredients adding sugars using non-parametric tests for matched samples. We evaluated the association between a reduction in sugars and starting NNS use in the post-implementation period using negative binomial regression. The use of any NNS increased from 37.9 to 43.6% (p < 0.001) after the law's implementation, NNSs increased among beverages, dairy-based beverages, yogurts, and desserts and ice creams (p < 0.05), driven mostly by increases in sucralose and stevia use (p < 0.05). We found that reformulated products that reduced the amount of sugars below the law's cutoff were more likely to start using an NNS in the post-implementation period (prevalence ratio: 12.1; 95%CI: 7.2-20.2; p < 0.001). Our results suggest that NNSs likely replaced sugars after the initial implementation of the law. Further analyses should explore how these changes may impact NNS consumption.},
