Food environment of bus terminals in the Rio de Janeiro metropolitan region / Ambiente alimentar de terminais rodoviários da região metropolitana do Rio de Janeiro

ABSTRACT PURPOSE To describe and analyze the healthiness of formal and informal food establishments in bus terminals of the metropolitan region of the state of Rio de Janeiro. METHOD An audit was conducted in 156 formal and 127 informal food establishments located in 14 bus terminals of the five most populous cities of the metropolitan region of Rio de Janeiro. Proportions of types of establishments and means (95%CI) of food availability indicators in formal and informal settings were calculated. For the formal setting, prices, proportions of accepted payment methods, days and hours of operation, and food categories with displayed advertising were described. RESULTS The healthiness of food establishments in bus terminals was low (less than 36%). On average, ultra-processed food subgroups were 250% more available for purchase than fresh or minimally processed food. Purchasing food at these places was convenient because several forms of payment were available, and the opening hours of the establishments followed the peaks of movement. In addition, 73.3% of the advertising referred to ultra-processed drinks, and the cost-benefit of buying ultra-processed food was better than fresh or minimally processed food. CONCLUSION The food environment of bus terminals in the metropolitan region of Rio de Janeiro promotes unhealthy eating. Regulatory public policies should focus on initiatives to limit the wide availability and advertising of ultra-processed food in spaces of great circulation of people.

RESUMO OBJETIVO Descrever e analisar a saudabilidade dos estabelecimentos com venda formal e informal de alimentos em terminais rodoviários da região metropolitana do Rio de Janeiro. MÉTODOS Realizou-se auditoria em 156 estabelecimentos formais e 127 pontos informais de venda de alimentos localizados em 14 terminais rodoviários das cinco cidades mais populosas da região metropolitana do Rio de Janeiro. Foram calculadas proporções de tipos de estabelecimentos e médias (IC95%) de indicadores de disponibilidade de alimentos nos ambientes formal e informal. Para o ambiente formal, foram descritos preços, proporções das formas de pagamento aceitas, dias e horários de funcionamento e categorias de alimentos com propaganda exposta. RESULTADOS A saudabilidade dos pontos de venda de alimentos nos terminais rodoviários era baixa (inferior a 36%). Em média, estavam disponíveis para compra 250% mais subgrupos de alimentos ultraprocessados do que in natura ou minimamente processados. Adquirir comida nesses locais era conveniente porque diversas formas de pagamento estavam disponíveis e os horários de funcionamento dos estabelecimentos acompanhavam os picos de movimentação. Além disso, 73,3% das propagandas se referiam a bebidas ultraprocessadas e o custo-benefício da compra de alimentos ultraprocessados era melhor que o de alimentos in natura ou minimamente processados. CONCLUSÃO O ambiente alimentar dos terminais rodoviários da região metropolitana do Rio de Janeiro promove uma alimentação não saudável. Políticas públicas de regulação devem se concentrar em iniciativas que limitem a ampla disponibilidade e publicidade de alimentos ultraprocessados nesses espaços de grande circulação de pessoas.

Encrucijadas sobre ¿qué vender?: máquinas expendedoras en entornos alimentarios universitarios / Crossroads about what to sell?: vending machines in university food environments

Introducción. Las máquinas expendedoras de bebidas y alimentos (MEBA) ganan presencialidad en universidades, lo que potencia aumento de peso en adultos jóvenes. Objetivo. reconocer la configuración de las MEBA para la construcción del ambiente alimentario saludable en una universidad de Colombia. Materiales y métodos. Diseño descriptivo multimodos, con aproximación empírica de: entrevista a tomadores de decisión (n=6) de la institución educativa; análisis de ventas durante un año (n=12.955) en las MEBA (n=12); caracterización por densidad nutricional de la oferta (n=152) y rastreo a comunicaciones circulantes asociadas con alimentación. El análisis consideró cuatro momentos: I-Relaciones; II-Canal MEBA; III-Nutrición y IV-Interacción. Los I y II se enfocaron en los componentes político, sociocultural, físico y económico. El III estudió el aporte nutricional de bebidas y alimentos para integrar resultados en el IV. Resultados. La ausencia de política sobre alimentación institucional como la visibilización comunicativa parecen potenciar condiciones sociales que refuerzan lógicas de: "mal necesario", "perfil de consumo ya existente", "ausencia de ejercicios académicos" y "experiencias negativas con alimentación saludable". Cimientos para ofertar con mayor demanda bebidas como refrescos y agua y, en alimentos, chocolate en diferentes formulaciones. En la clasificación por densidad nutricional se encontró que las bebidas fueron clasificadas como "no saludable" (51,6%); "algo saludable" (28,1%) y "saludable" (20,3%). Los alimentos "algo saludable" (44,9%); "no saludable" (32,2%) y "saludable" (22,9%). Conclusiones. la universidad, espacio de formación, requiere realizar esfuerzos de comprensión sociocultural, gerencia alineada a normativas de promoción de salud para incidir en la calidad nutricional ofertada a la comunidad universitaria(AU)

Introduction. Food and beverage vending machines (MEBA) are gaining presence in universities, which promotes weight gain in young adults. Objective. to recognize the configuration of the MEBA for the construction of a healthy food environment in a university in Colombia. Materials and methods. multimodal descriptive design, with an empirical approach of: interview with decision makers of the educational institution (n=6); analysis of sales during one year (n=12,955) in the MEBAs (n=12); characterization by nutritional density of the offer (n=152) and tracking of circulating communications associated with food. The analysis considered four moments: I-Relationships; II-MEBA Channel; III-Nutrition and IV-Interaction. I and II focused on the political, sociocultural, physical and economic components. The III studied the nutritional contribution of drinks and foods to integrate results in the IV. Results. the absence of a policy on institutional food such as communicative visibility seems to enhance social conditions that reinforce logics of: "necessary evil", "already existing consumption profile", "absence of academic exercises" and "negative experiences with healthy eating". Foundations to offer with greater demand drinks such as soft drinks and water and, in food, chocolate in different formulations. In the classification by nutritional density, it was found that the drinks were classified as "unhealthy" (51.6%); "something healthy" (28.1%) and "healthy" (20.3%). "Somewhat healthy" foods (44.9%); "unhealthy" (32.2%) and "healthy" (22.9%). Conclusions. the university, a training space, requires efforts at sociocultural understanding, management aligned with health promotion regulations to influence the nutritional quality offered to the university community(AU)

Relationship between food environment, social isolation and diet quality in Brazil / Relación entre el entorno alimentario, el aislamiento social y calidad de la dieta en Brasil. Introducción

Introduction. The COVID-19 pandemic has impacted diet quality in differentways. In this context, community, organizational and consumer nutrition environments can influence the eating pattern. Objective. The purpose of this study was to identify how quarantine during the COVID-19 pandemic changed the diet in Brazil. Materials and methods. A natural experiment organized into experimental (social-isolated group - SIG) and control groups (non-isolated group - CG) was conducted with data collection from an online survey at the beginning of the pandemic (T0) and in the less restrictive period of 2020 (T1). Pre-post improvements in diet quality (IDQ) were determined for the SIG and CG. Intro-intergroup changes were tested using the Mann­Whitney and Wilcoxon signed rank tests. The intervention effect was estimated using crude and adjusted difference- indifference in multilevel regression analysis accounting for repeated measures. Results. A sample of 565 Brazilian adults answered the questionnaire at T0 and T1. IDQ was favored twice or more by attitudes such as buying food directly from farmers/street markets, reducing requests for food delivery, and increasing time spent on eating activities and the frequency of cooking. The isolated group had no IDQ at T1, whereas the no isolated group, who worsened diet quality (6.1%) at T0, improved it at T1 (4.8%). Conclusions. The restrictive quarantine forced the non-isolated population to have an experience comparable to a food desert, negatively affecting their diet(AU)

COVID-19 ha impactado la calidad de la dieta de diferentes maneras. Los entornos comunitarios, organizacionales y nutricionales de los consumidores pueden influir en los patrones dietéticos. Objetivo. el objetivo de este estudio fue identificar cómo la cuarentena durante la pandemia de COVID-19 cambió la dieta en Brasil. Materiales y métodos. Se realizó un experimento natural organizado en grupos experimental (grupo socialmente aislado - SIG) y control (grupo no aislado - GC) con datos recolectados en una encuesta en línea al inicio de la pandemia (T0) y en el momento menos restrictivo de 2020 (T1). Se determinaron mejoras pre-post en la calidad de la dieta (IDQ) para SIG y GC. Los cambios intra-intergrupo se probaron utilizando las pruebas de rangos con signos de Mann-Whitney y Wilcoxon. El efecto de la intervención se estimó utilizando diferencias crudas y ajustadas en el análisis de regresión multinivel, teniendo en cuenta medidas repetidas. Resultados. Una muestra de 565 adultos brasileños respondió el cuestionario en T0 y T1. IDQ se vio favorecido dos o más veces por actitudes como comprar alimentos directamente de los agricultores/mercados callejeros, reducir los pedidos de entrega de alimentos y aumentar el tiempo dedicado a las actividades alimentarias y la frecuencia de cocinar. El grupo aislado no mostró IDQ en T1, mientras que el grupo no aislado, que tenía peor calidad de la dieta (6,1%) en T0, mejoró en T1 (4,8%). Conclusiones. La cuarentena restrictiva obligó a la población no aislada a tener una experiencia comparable a un desierto alimentario, afectando negativamente su dieta(AU)

In the evaluation of nutritional aspects and environmental impacts, foods of animal origin represented 26.52% of the total in kg and 69.78% of WF. A vegetal based food had the highest GHG impact due to its origin. Regarding the EE calculations, the general assessment showed a result of 0.626 for foods of animal origin and 0.3838 for those of vegetable origin. Conclusions. It corresponds to the food services for communities to consider, in the planning of the menu, in addition to the nutritional and sanitary quality of the food offer, the environmental impacts that it generates(AU)

ANÁLISIS DE BRECHAS EN LA CALIDAD DE DIETA DE LA POBLACIÓN ARGENTINA DE 1 A 69 AÑOS. ESTUDIO ABCDIETA / GAPS ANALYSIS IN THE DIETARY QUALITY OF THE ARGENTINE POPULATION 1 TO 69. ABCDieta STUDY

Una de las formas de estudiar patrones alimentarios es a través de Índices de Calidad de Dieta, algunos de los cuales se basan en la densidad nutricional de los alimentos. El concepto resume en una medida la relación entre energía y nutrientes a promover y a limitar, visibilizando las adecuaciones de nutrientes en forma paralela al equilibrio energético. El objetivo del trabajo es estudiar la calidad de dieta y sus brechas en una muestra de la población urbana de Argentina y describir la conformación del patrón alimentario según niveles de calidad nutricional utilizando el enfoque de densidad nutricional. Métodos: Se analizaron los datos de una encuesta alimentaria por autorregistro sobre 1030 sujetos de 11 ciudades de Argentina. Partiendo de sus consumos alimentarios se determinó la densidad nutricional a través de un índice (IDN) basado en energía, 9 nutrientes a promover y 4 a limitar. Se analizó el IDN de la dieta total, de 5 momentos de ingesta y de grupos de alimentos. Resultados: La calidad de dieta promedio alcanzó la mitad del estándar de un patrón saludable (10,6 sobre 20 puntos). Los mejores resultados se concentraron en menores de 3 años (17% presentaron una buena calidad de dieta). Comparados con el estándar, la calidad de almuerzos y cenas superaron a desayunos y meriendas. Legumbres, hortalizas, frutas y lácteos fueron los grupos con mayores brechas de calidad. Alimentos ocasionales y feculentos en general ­también carnes­ reflejaron excesos. Preparaciones y comidas rápidas alcanzaron hasta un 21 % de la densidad nutricional total. Conclusiones: El enfoque de densidad nutricional complementa la comprensión de las brechas alimentarias en la población argentina, al aportar argumentos en favor de intervenciones orientadas a un mejor equilibrio en particular en alimentos protectores, deficitarios en la conformación del patrón alimentario

Diet Quality Index represents one way to study food patterns. Some of them are based on the nutritional density of foods. The concept summarizes the relationship between energy and nutrients to promote and limit, making visible nutrient adequacy in line with energy balance. The objective is to study the quality of the diet and its gaps in a sample of the urban population of Argentina and to describe the food pattern according to levels of nutritional quality using the nutritional density approach. Methods: Data from a self-registration dietary survey on 1030 subjects from 11 cities in Argentina were analyzed. It was determined the nutritional density of the reported consumptions through an index (IDN) based on energy, 9 nutrients to promote and 4 to limit. The IDN of the total diet, 5 moments of intake and food groups was analyzed. Results: The average diet quality was half the standard of a healthy pattern (10.6 out of 20 points). The best results were concentrated in children under 3 years of age (17% presented a good quality diet). Compared to the standard, the quality of lunches and dinners exceeded breakfasts and snacks. Legumes, vegetables, fruits and dairy products were the groups with the largest quality gaps. Occasional and starchy foods in general ­also meats­ reflected excesses. Preparations and fast meals reached up to 21% of the total nutritional density. Conclusions: The nutritional density approach complements the understanding of food gaps in the Argentine population, providing arguments in favor of interventions aimed at a better balance, particularly in protective foods, which are deficient in the conformation of the food pattern

Quality of children's menus in malls in Brazil / Qualidade dos menus infantis em shoppings centers do Brasil

Abstract Objectives: characterize the availability and assess the nutritional quality of children's menus ofered in regular and fast food restaurants in Brazilian malls. Methods: this is an observational and cross-sectional study. Data were collected on the websites of each restaurant and in food sales applications, with a questionnaire consisting of two sections: characterization of the restaurant and characterization of the children's menu. Data collection took place in ten capitals in the fve regions of Brazil. Results: 116 children's menus were evaluated. The study identifed a higher number of regular (n=70, 60%) than fast-food (n=46,40%) restaurants. The cooking methods most used in the main dishes were grilled (n=236, 64%) and boiled (n=74, 20%), and in the side dishes were boiled (n=204, 53%) and fried (n=109, 28%). Only 40% (n=46) of the menus contained vegetables. Less than 10% (n=seven) ofered fruit as dessert, 31% (n = 36) had drinks included in the children's menu and 22% (n=25) ofered gifts associated with the menu. Only 32 (28%) restaurants had the combination of beans and rice. Conclusion: most of the options ofered to children were of low nutritional quality, with low ofer of vegetables, fruits and the traditional beans and rice. The beverages included in the menus, most of them sugary, can contribute to a high-energy intake. There is a need to provide healthy options and encourage these choices.

Resumo Objetivos: caracterizar a disponibilidade e a qualidade nutricional dos menus infantis nos restaurantes e estabelecimentos de fast-foods em Shoppings Centers no Brasil. Métodos: trata-se de um estudo observacional e transversal. Os dados foram coletados nos websites de cada estabelecimento e em aplicativos de vendas de alimentos, com questionário composto por duas seções: Caracterização do estabelecimento e caracterização do menu infantil. A coleta dos dados ocorreu em dez capitais distribuídas nas cinco regiões do Brasil. Resultados: foram avaliados 116 menus infantis. Maior número de estabelecimentos foi classifcado como restaurante do que fast-food. Os métodos de cocção mais utilizados nos pratos principais foram grelhados (n=236, 64%) e cozidos (n=74, 20%), e nos acompanhamentos foram cozidos (n=204, 53%) e fritos (n=109, 28%). Apenas 40% (n=46) dos menus continham hortaliças. Menos de 10% (n=sete) ofertavam fruta como sobremesa; 31% (n=36) constavam bebida inclusa no menu infantil; 22% (n=25) ofereciam brindes associados ao menu. Apenas 32 (28%) estabelecimentos apresentavam a combinação feijão e arroz. Conclusão: a maioria das opções ofertadas às crianças era de baixa qualidade nutricional, com pouca oferta de hortaliças, frutas e do tradicional feijão e arroz. As bebidas incluídas nos menus, a maioria açucaradas, podem contribuir para uma elevada ingestão energética. Constata-se a necessidade de disponibilizar opções saudáveis e incentivar essas escolhas.

Conceito e aplicação da rastreabilidade de alimentos: uma revisão / Concept and application on food traceability: a review

A rastreabilidade de alimentos (RTA) é definida como um conjunto de procedimentos que permite detectar a origem e acompanhar a movimentação de um produto ao longo da cadeia produtiva, mediante elementos informativos e documentos registrados. A crescente complexidade da produção e distribuição de alimentos demanda o desenvolvimento de iniciativas que promovam maior segurança e qualidade de produtos. O objetivo deste trabalho foi realizar uma revisão da literatura científica sobre o conceito de rastreabilidade de alimentos e identificar as estratégias de aplicação desta ferramenta. Concluiu-se que a implementação da RTA está vinculada a ações governamentais por meio de legislações e órgãos de fiscalização, bem como o uso desta ferramenta ao longo da cadeia produtiva de alimentos requer cada vez mais recursos tecnológicos que possam integrar os diferentes agentes da cadeia de suprimentos.

Food traceability (RTA) is defined as a set of procedures that make it possible to detect the origin and monitor the movement of a product along the production chain, using information elements and registered documents. The growing complexity of food production and distribution demands the development of initiatives that promote greater product safety and quality. The objective of this work was to carry out a review of the scientific literature on the concept of food traceability and to identify strategies for applying this tool. It is concluded that the implementation of the RTA is linked to government actions through legislation and inspection bodies, as well as the use of this tool along the food production chain requires more and more technological resources that can integrate the different agents of the supply chain supplies.

Migração de partícula alergênica através de embalagem pet / Migration of allergen particles through pet

Para garantia da segurança dos consumidores muitas decisões na indústria alimentícia são tomadas com "margem de segurança", uma delas é a dispersão de partículas alergênicas em contaminações cruzadas. Em estoques de bebidas embaladas, diversas unidades que não possuem ingredientes alergênicos ou traços são descartadas quando um produto alergênico entra em contato, mesmo que pela parte externa. O presente estudo teve como objetivo avaliar se a partícula alergênica externa migra pela embalagem de PET e contamina a bebida não alergênico. Para isso, um produto em embalagem PET sem ingredientes ou partículas alergênicas (água) teve sua parte externa exposta a um ingrediente alergênico (soja) em meio aquoso e oleoso por 1, 24, 48 e 72 horas, demonstrando que não há migração para a parte interna.

To ensure the safety of consumers, many decisions in the food industry are made with "margin of safety", one is the dispersion of allergenic particles in cross-contamination. In stocks of packaged beverages, several units that do not contain allergenic ingredients or traces are discarded when an allergenic product comes into contact, even out of pack. The objective of this study is to evaluate whether the external allergenic particle migrates through the PET packaging and contaminates the non-allergenic food. A product in PET packaging without allergenic ingredients or particles (water) has your external part exposed to an allergenic ingredient (soy) in an aqueous and oily medium for 1, 24, 48 and 72 hours, and tested if are migration.

Additifs alimentaires: inventaire des substances ajoutées aux denrées alimentaires de large consommation dans l'Ouest algérien / Food additives : inventory of substances added to consumer foods in Western Algeria

Introduction- Les additifs alimentaires sont utilisés pour prolonger la durée de conservation des denrées préparées ou édulcorer une boisson par exemple. Dans cette étude, nous dressons un état des lieux des additifs alimentaires utilisés dans quelques denrées alimentaires de large consommation commercialisées dans la ville d'Oran (Ouest Algérien). Matériels et méthodes- Une étude transversale descriptive a été réalisée au niveau des superettes et magasins d'alimentation générale de la ville d'Oran pour lister les additifs alimentaires incorporés à quelques aliments de large consommation Dans un premier temps, une étude descriptive transversale a été réalisée pendant trois mois au sein de trois structures hospitalières de l'Ouest algérien. Résultats-Au total, 114 additifs alimentaires ont été répertoriés. Tous les additifs inventoriés sont listés dans le journal officiel Algérien N°30 du 16 Mai 2012.Les additifs répertoriés ne sont pas sans risques pour la santé du consommateur. Certains additifs comme le colorant caramel ou SIN150d est retrouvé dans 3 marques locales de biscuits et 4 marques de boissons locales (17,5%) ; le benzoate de sodium ou SIN211 dans 12 marques de boissons et 2 marques de confiture (16,09%) ; le butylhydroxyanisole (BHA) ou SIN320 dans une marque de chocolat, de margarine et de chips (1,67%). Globalement, les étiquettes des produits sont conformes à la réglementation Algérienne à l'exception de quelques manquements comme la nature de l'arôme qui ne fut pas toujours spécifiée Conclusion-L'étude a révélé une importante utilisation des additifs alimentaires. Le niveau de risque pour la santé du consommateur que pourraient présenter ces substances nécessite une large sensibilisation du consommateur, notamment une consommation modérée des denrées alimentaires industriellement préparées.

Compliance in handling of donated raw breast milk to human milk banks regarding microbiological quality / Conformidade no manuseio do leite materno cru doado aos bancos de leite humano em relação à qualidade microbiológica

Abstract Objectives: microbiological quality of raw human milk (HM) from donors at the HMB (Human Milk Bank) of Santa Casa de Misericórdia de Ouro Preto was evaluated. Methods: the microbiological quality of milk from each of 10 donors in triplicate (30 samples) was evaluated by enumeration of Staphylococcus aureus and total aerobic mesophiles (surface plating) and total and thermotolerant coliforms (Most Probable Number - MPN). A questionnaire and a checklist were applied after the end of sample collection to verify the compliance of milk extraction and storage procedures by the donors. Results: inadequacies in the procedures for expression and storage of donated HM were observed. The presence of all microorganisms studied were verified in the milk of all donors, and in some cases exceeded the safety limits. The checklist indicated that some necessary hygienic-sanitary procedures were not carefully performed, making it important to properly guide the donors. Conclusions: this study points to an unfavorable scenario for the safety and quality of donated HM, and it is important to encourage further studies to be conducted so that the Brazilian network of HMB adopts stricter criteria for instructions on procedures and support for HM donors.

Resumo Objetivos: avaliou-se a qualidade microbiológica do leite humano (LH) cru de doadoras do Banco de Leite Humano (BLH) da Santa Casa de Misericórdia de Ouro Preto. Métodos: a qualidade microbiológica do leite de cada uma das 10 doadoras em triplicata (30 amostras) foi avaliada por meio da enumeração de Staphylococcus aureus e mesóflos aeróbios totais (plaqueamento em superfície) e coliformes totais e termotolerantes (Número Mais Provável -NMP). Para verificar a conformidade dos procedimentos de extração e armazenamento do leite pelas doadoras, aplicou-se um questionário e um checklist após o término da coleta das amostras. Resultados: observou-se inadequações nos procedimentos de expressão e armazenamento do LH doado. A presença de todos os microrganismos estudados foram verificados no leite de todas as doadoras e, em alguns casos, excedeu os limites de segurança. O checklist indicou que alguns procedimentos higiênico-sanitários necessários não foram realizados criteriosamente, tornando importante orientar adequadamente as doadoras. Conclusões: este estudo aponta um cenário desfavorável para a segurança e a qualidade do LH doado, sendo importante incentivar mais estudos a serem realizados para que a rede brasileira de BLH adote critérios mais rigorosos de instruções sobre procedimentos e suporte para doadoras de LH.

Effectiveness Comparison of Polysaccharides, Proteins, and Lipids as Composite Edible Coatings on the Quality of Food Products / Comparación de la Efectividad de Polisacáridos, Proteínas y Lípidos como Recubrimientos Compuestos Comestibles en la Calidad de los Productos Alimenticios

Background: This research was motivated by the complaints of tomato farmers about their crops that quickly rotted before being sold, as well as the many research results (raw materials and methods) that edible coating films could not be applied optimally. Objectives: The research was a practical recommendation by comparing the effectiveness of raw materials (polysaccharides, proteins, and lipids) with the dipping and spray methods. Materials and methods used in the comparison process were the application of Structural Equation Modeling (SEM) with the Partial Least Square (PLS) approach. Results: Dipping has a strong effect (f2 ≥ 0.35; p<0.05), while spray had a moderate effect (f2: 0.15-0.35; p<0.05). Thus, the role of dipping as a mediator was more dominant than spray. Compared to proteins and lipids, polysaccharides had the best effectiveness (ß:0.460-0.584; f2: 0.15-0.35; p<0.05). Conclusion: the three ingredients improved the quality of tomatoes, and the dipping method was easier to apply by farmers than the spray method, which had many obstacles in its application

Antecedentes: esta investigación está motivada por las quejas de los productores de tomate sobre sus cultivos que se pudren rápidamente antes de ser vendidos, así como por los muchos resultados de la investigación (materias primas y métodos) de que las películas de recubrimiento comestibles no se pudieron aplicar de manera óptima. Objetivos: La investigación consiste en recomendaciones prácticas mediante la comparación de la eficacia de las materias primas (polisacáridos, proteínas y lípidos) con los métodos de inmersión y aspersión. Métodos: El método utilizado en el proceso de comparación es la aplicación del modelo de ecuaciones estructurales (SEM) con el enfoque de mínimos cuadrados parciales (PLS). Resultados: La inmersión tiene un efecto fuerte (f2 ≥ 0,35; p<0,05), mientras que la pulverización tiene un efecto moderado (f2: 0,15-0,35; p<0,05). Por lo tanto, el papel de la inmersión como mediador es más dominante que el del rociado. Los polisacáridos tienen la mejor eficacia (ß:0,460-0,584; f2: 0,15-0,35; p<0,05) en comparación con las proteínas y los lípidos. Conclusión: es que los tres ingredientes pueden mejorar la calidad de los tomates, y el método de inmersión es más fácil de aplicar por los agricultores que el método de aspersión, que tiene muchos obstáculos en su aplicación

Perceptions of healthy food, and perceived facilitators and barriers to buying and consuming healthy food, among female caregivers in Soweto, South Africa

Background. Obesity poses a continuous health challenge in South Africa and disproportionately affects black African households. To target obesity in these settings, it is crucial to have an in-depth understanding of food choices made by affected households. Objectives. To explore how healthy food is perceived by women living in Soweto, and the facilitators of and barriers to buying and consuming this food. Methods. This was a qualitative study that utilized semi-structured interviews. Ten participants were recruited using purposive sampling. Interviews were audio-recorded, transcribed verbatim and analyzed using thematic analysis. The study took place in Soweto, South Africa, and was conducted from February to May 2019. Results. Six themes were developed from the data: perceptions of healthy food; protecting family members from unhealthy food; learning about healthy food; appreciation by the family; home-cooked food v. food bought on the street; and budgetary restrictions. The first three themes were grouped by the overarching theme 'consciousness of healthfulness of food', and the last three themes were grouped by the theme 'influences of the family and environment on food choice'. Conclusions. A focus on the whole family's dietary behaviours is recommended and, in future interventions, guidance communicated in intervention materials should be tailored to existing knowledge of healthy eating.

Evaluation of some nutritional quality criteria of seventeen Moroccan dates varieties and clones, fruits of date palm (Phoenix dactylifera L) / Avaliação de alguns critérios de qualidade nutricional de 17 variedades e clones marroquinos de datas, frutos de tamareira (Phoenix dactylifera L)

Date fruit is known to be the staple food in the Arab countries. It provides a lot of potential health benefits and can be the essential source of nutrients. The majority of Moroccan varieties are not characterized for their chemical, biochemical and quality properties. The aim of this work was to assess the chemical composition of 17 varieties of Moroccan date fruits (Phoenix dactylifera L.) and to determine their nutritive components. The analysis showed that the dates are rich in sugars (51.80-87.98%), they contain low concentration of proteins (1.09-2.80%) and lipids (0.16-0.39%). The predominant mineral is potassium (1055.26-1604.10 mg/100 g DW). Moreover, they contain high concentrations of malic acid (69.48-495.58 mg/100 g (DW)), oxalic acid (18.47-233.35 mg/100 g DW) and tartaric acid (115.70-484.168 mg/100 g DW). These results suggest that the date fruit are nutritious and can be an excellent source for human nutrition and health benefits.

Interspecific variations in external and internal egg quality among various captive avian species from Punjab, Pakistan / Variações interespecíficas na qualidade externa e interna do ovo entre várias espécies de aves em cativeiro de Punjab, Paquistão

Present study was planned to determine variations in external and internal quality egg parameters of different avian species including ostrich Struthio camelus, ducks Anas platyrhynchos, chicken Gallus gallus, turkeys Meleagris gallopavo and grey francolin Francolinus pondicerinus. All the birds were kept under similar rearing conditions. A total of 150 eggs were collected for each species to record external features of these eggs. Statistically significant (p<0.05) variations were recorded in egg weight, egg length and egg width between ostrich, ducks, chicken, turkey and quail eggs. Significantly (p<0.05) higher egg weight, egg length and egg width was observed for ostrich eggs while the same was lowest for grey francolin eggs. Similarly, significantly (p<0.05) greater shape index and egg volume values were observed for ostrich eggs while lowest shape index values were recorded for turkey eggs and egg volume was lowest for grey francolin. Significantly, higher (p<0.05) values of egg density were noted for eggs of the quail and the same were lowest for ostrich eggs. Non-significant variations in egg density values were observed between eggs of the ducks, chicken, turkey and grey francolin. It has been concluded that the positive correlations between the internal and external egg quality traits indicated that the traits can be improved through selection.

O presente estudo foi planejado para determinar variações nos parâmetros externos e internos de qualidade dos ovos de diferentes espécies de aves, incluindo avestruz Struthio camelus, patos Anas platyrhynchos, frango Gallus gallus, perus Meleagris gallopavo e francolin cinza Francolinus pondicerinus. Todas as aves foram mantidas em condições de criação semelhantes. Um total de 150 ovos foi coletado para cada espécie para registrar as características externas desses ovos. Variações estatisticamente significativas (p < 0,05) foram registradas no peso do ovo, comprimento do ovo e largura do ovo entre os ovos de avestruz, patos, galinha, peru e codorna. Significativamente (p < 0,05) maior peso do ovo, comprimento e largura do ovo foram observados para ovos de avestruz, enquanto o mesmo foi menor para ovos de francolina cinza. Da mesma forma, significativamente (p < 0,05) maiores valores de índice de forma e volume de ovo foram observados para ovos de avestruz, enquanto os menores valores de índice de forma foram registrados para ovos de peru e o volume de ovo foi menor para francolina cinza. Significativamente, maiores (p < 0,05) valores de densidade de ovos foram observados para ovos de codorna e os mesmos foram menores para ovos de avestruz. Variações não significativas nos valores de densidade de ovos foram observadas entre os ovos de pato, frango, peru e francolina cinza. Concluiu-se que as correlações positivas entre as características internas e externas de qualidade do ovo indicaram que as características podem ser melhoradas por meio da seleção.

Healthy and safe school cafeteria program: a randomized controlled study / Programa cantinas escolares saudáveis e seguras: um estudo controlado randomizado

ABSTRACT Objective To assess the effect of an educational intervention program focused on health risk conditions, based on an assessment of the hygiene and quality of food sold in school cafeterias. Methods This is a controlled, parallel, randomized, two-arm, community study. Public and private schools with cafeterias were invited to participate. This study was conducted in 27 school cafeterias in northern and northwestern Rio Grande do Sul, a state in southern Brazil. Representatives of the school communities in the intervention group received an educational program consisting of 160-hour distance training. The most relevant outcomes were the assessment of the hygienic conditions and composition of the menus sold in school cafeterias. All outcomes were analyzed as intention-to-treat and per-protocol. For the analysis of continuous data with normal distribution, an analysis of covariance and the Generalized Linear Model were used. The level of statistical significance considered was p<0.05 for a 95% CI. Results No statistically significant difference was observed between the intervention group and the control group in the studied outcomes. There was a reduction of 76.2 points in the score for hygienic handling conditions (95% CI: -205 to 357; p=0.581). Regarding menu composition, the difference between groups was 0.48% (95% CI: -2.69 to 3.64; p=0.760) for ultra-processed foods, 0.23% (95% CI: -1.13 to 1.60; p=0.740) for processed foods, and 1.02% (95% CI: -2.59 to 4.64; p=0.581) for fresh foods. Conclusion There is not enough evidence to conclude that the intervention had a positive impact on any of the outcomes studied.
