Involvement of Brazilian adolescents in home cooking: An exploratory analysis (EVA-JF Study).

OBJECTIVE: The aim of this study was to investigate the involvement of Brazilian adolescents in home cooking, estimating its associations with sex and socioeconomic status. METHODS: This cross-sectional study involved a probabilistic sample of 14- to 19-y-olds enrolled in 29 public schools in the municipality of Juiz de Fora, MG, Southeast Brazil (n = 835). To assess involvement in home cooking, a 12-question questionnaire was used. The content was based on the Brazilian Food Guide, which encourages the acquisition, development, and sharing of culinary skills. Pearson's χ test and Poisson regression models were carried out, without and with adjustments. RESULTS: Most of the adolescents did not usually participate in meal planning (61%), and in the choice/purchase of food and culinary ingredients (67%). Boys were less likely to know how to cook "from scratch", positively self-evaluate their culinary skills, enjoy cooking, wish to learn more about cooking and meal preparation, and to participate frequently in the planning and preparation of meals. Belonging to a lower socioeconomic status represented a greater probability of preparing meals alone for the family. CONCLUSIONS: We verified an alarming prevalence of adolescents with behaviors unaligned with Brazilian Food Guide recommendations; that is, most of them, especially boys, were not involved in home cooking. Adolescence may present a window of opportunity for the development of culinary skills, resulting in long-term benefits for the population's diet quality. Furthermore, to change a historical pattern that overloads women's daily lives, it is necessary to encourage, from an early age, the presence of boys in the kitchen.

Soaking to Reduce Potassium and Phosphorus Content of Foods.

OBJECTIVES: To achieve and maintain normal serum potassium and phosphorus levels reducing potassium and phosphorus intake is frequently recommended for adults living with chronic kidney disease. Exploring food preparation methods to reduce potassium and phosphorus content appears warranted. The study aim is to determine the impact of soaking foods in hot water on potassium and phosphorus content in a variety of plant- and animal-based foods. METHODS: Twenty foods were selected that are common staples in Brazilian diet patterns. Food was soaked for 5-10 minutes in deionized water that had been brought to a boil and then removed from heat using a 5-part water to 1-part sample ratio. The potassium content was determined by flame photometry. The phosphorus content was determined by visible ultraviolet spectrophotometry. RESULTS: Soaking foods resulted in a reduction in potassium and phosphorus. Potassium reduction in beef, green leafy vegetables, and grains was 40-49%; in chicken, fish, and nonleafy vegetables 30-39%; and tubers 10-20%. Phosphorus reduction in grains and beans was 30-39%; in nonleafy vegetables 20-29%; and beef, chicken, and fish 10-20%. CONCLUSIONS: Soaking foods in hot water for 5-10 minutes reduces potassium and phosphorus content. Using this technique to prepare foods may be a more acceptable alternative to longer demineralization periods making it easier for adults living with chronic kidney disease to follow diet recommendations.

Percepções de adultos jovens brasileiros sobre o ato de cozinhar / Perceptions of Brazilian young adults about cooking

Introdução: Cozinhar em casa pode promover uma alimentação mais saudável. Porém, uma possível redução na transmissão de conhecimentos e habilidades culinárias parece prejudicar a confiança e a autonomia dos jovens para preparar as refeições. Para informar o desenvolvimento de iniciativas que apoiem os jovens adultos a superar as barreiras para cozinhar e melhorar a qualidade da dieta, é importante investigar o processo de socialização culinária no contexto de seu próprio curso de vida. Objetivo: Este estudo qualitativo teve como objetivo explorar como jovens adultos que têm o hábito de cozinhar percebem seu envolvimento com essa prática e identificar quais agentes socializadores culinários fizeram parte de seu processo de aprendizagem. Método: Entrevistas abertas baseadas na abordagem da perspectiva do curso de vida foram realizadas com adultos jovens brasileiros de 19 a 24 anos de ambos os sexos e analisadas tematicamente. Resultados: As percepções sobre cozinhar e sobre aprender a cozinhar levaram à criação de seis temas: (1) "Cuidar de mim"; (2) "Sentimentos (des)agradáveis"; (3) "Promover o convívio"; (4) "Preocupação com os resultados"; (5) "Habilidades necessárias"; e (6) "Agentes de socialização". Conclusões: As iniciativas para permitir que os adultos jovens superem as barreiras para cozinhar e potencialmente melhorar a qualidade da dieta precisam se concentrar não apenas no desenvolvimento prático de habilidades culinárias, mas também em habilidades, como planejamento. Também é importante fomentar mensagens positivas envolvendo autocuidado, prazer e convívio. Formas de usar a internet e as mídias sociais para engajar essa população a cozinhar mais merecem ser mais bem exploradas.

Introduction: Cooking at home is conducive to better diet quality and can help improve health. Nevertheless, the reduced transmission of culinary knowledge and skills worldwide hinders young adults' confidence and autonomy to prepare meals. To inform the development of initiatives that support young adults to overcome barriers to cook and improve their diet quality, it is important to investigate the process of culinary socialization in the context of their own life course. Objective: This qualitative study aimed to explore how young adults who cook perceive their involvement with this practice and to identify which culinary socializing agents were part of their learning process. Method: Open interviews based on the life-course perspective approach were conducted with male and female Brazilian young adults aged 19-24 years-old and thematically analysed. Results: Perceptions about cooking and about learning how to cook led to the creation of six themes: (1) "Caring about myself"; (2) "(Un)pleasant feelings"; (3) "Promoting conviviality"; (4) "Worrying about outcomes"; (5) "Skills needed"; and (6) "Socializing agents". Conclusions: Initiatives to enable young adults overcoming barriers to cook and potentially improve their diet quality need to focus not only on practical cooking skills development, but also on planning. Also important is to foster positive messages involving self-care, pleasure, and conviviality. Ways of using the internet and social media to engage this population to cook more deserves to be further explored.

How was the cooking skills and healthy eating evaluation questionnaire culturally adapted to Brazil? / Como o questionário de avaliação das habilidades culinárias e alimentação saudável foi adaptado transculturalmente ao Brasil?

Abstract The study described the cross-cultural adaptation process of the American Cooking Skills and Healthy Eating questionnaire to Brazil. Six stages were followed: Translation; Synthesis of translations; Back-translations; Expert Committee; Synthesis of final version; and the Pretest (self-administered online questionnaire in a Brazilian University). Participants responded to the translated questionnaire twice for test-retest. Conceptual, item, semantic, operational and measurement equivalences were evaluated between original and translated questionnaires, as well as the internal consistency and test-retest reliability. Item, conceptual, semantic equivalences between original and Brazilian questionnaires were reached before the Expert Committee stage. Specific cooking techniques and terms were adapted. Forty-eight students answered the questionnaire in the pre-test stage, achieving the operational and measurement equivalences with kappa's agreement from moderate to substantial, and satisfactory to excellent correlations between measures. Only two measures showed low internal consistency. The combination of stages and equivalences approaches used in this cross cultural adaptation study provided lessons for further Nutrition's researches, disclosing the complexity of cooking skills concepts.

Resumo O estudo descreveu o processo de adaptação transcultural do questionário estadunidense de avaliação das habilidades culinárias e alimentação saudável para o Brasil. Seis estágios foram conduzidos: Tradução; Síntese da tradução; Retrotradução; Comitê de Juízes; Síntese da versão final; e Pré-teste (preenchimento do questionário online). Participantes responderam duas vezes ao questionário traduzido. Equivalências conceitual, do item, semântica, operacional e de mensuração foram avaliadas entre os questionários original e traduzido, bem como a consistência interna e a confiabilidade teste-reteste. Alcançaram-se as equivalências do item, conceitual e semântica entre as versões antes do Comitê de Juízes. Técnicas e termos culinários específicos foram adaptados. Quarenta e oito estudantes responderam o questionário no pré-teste, alcançando equivalências operacional e de mensuração, concordância kappa moderada a substancial, e correlações entre as medidas satisfatórias a excelentes. Duas escalas apresentaram baixa consistência interna. A combinação das abordagens dos estágios e equivalências usadas na adaptação transcultural do questionário proveu lições para futuras pesquisas em Nutrição, revelando a complexidade dos conceitos de habilidades culinárias.

"Healthy", "usual" and "convenience" cooking practices patterns: How do they influence children's food consumption?

This study identified adults' cooking practices patterns and tested their associations with children's consumption of ultra-processed foods. Cross-sectional study conducted with 551 adult-child pairs from São Paulo, Brazil. Children's food consumption was collected through dietary recalls. Adults' cooking practices were identified using a questionnaire developed for the Brazilian's context. Principal Component Analysis has been employed to identify cooking patterns and linear regression models (crude and adjusted for sociodemographic variables) have been used to test associations between pattern's scores and contribution of ultra-processed foods to total energy at dinners. Three cooking patterns were identified: "Healthy", "Usual" and "Convenience". The first two patterns reflected behaviors of people who mostly cook "from scratch". Only the Healthy pattern (confidence to cook several meals using fresh foods and natural seasonings; healthier cooking techniques) was inversely associated with ultra-processed food consumption (ß = -4.1; p = 0.002), whereas the Convenience pattern (less frequency and time to cook, using microwave and ready-to-heat meals) was positively associated with (ß = 3.6; p = 0.008). Our results suggest that cooking at home, as an isolated action, is not enough to protect the consumption of ultra-processed foods. To promote healthy eating among children, the adults' cooking practices should be aligned with the preparation of meals made "from scratch", taking into account the healthiness of what is being cooked.

Development of culinary recipes in an intervention program with Brazilian university students / Desenvolvimento de receitas culinárias em programa de intervenção com universitários brasileiros

ABSTRACT Objective Develop and test recipes for a cooking skills intervention program aimed at students of a Brazilian university. Methods Culinary recipes were selected for the Nutrition and Culinary in the Kitchen program, which offers cooking classes for participants to practice and develop their cooking skills. The Nutrition and Culinary in the Kitchen program is based on the Cooking with a Chef program of the United States of America. A literature search was conducted to establish criteria for the selection and development of recipes. A decision tree was constructed to determine if Cooking With a Chef recipes were appropriate for the Nutrition and Culinary in the Kitchen program. Recipes were evaluated in the laboratory by untrained university students using an acceptance test that comprised the analysis of sensorial attributes and healthiness criteria. Results Of the 32 developed recipes, nine were based on the Cooking With a Chef program. Recipes were adapted to increase the use of fresh fruits, whole grains, and vegetables; eliminate ultra-processed foods; and take into account local food habits and seasonality of ingredients. In the first test, 53.3% (n=16) of the dishes received an acceptance score of less than 70.0% mainly because of unsatisfactory taste. Culinary recipes considered inadequate were redesigned in terms of ingredients and/or cooking methods and were retested until achieving a score of 100.0%. Conclusion Culinary recipes adapted to the Brazilian food culture and the target audience with the use of healthy ingredients and cooking techniques were considered appropriate for the Nutrition and Culinary in the Kitchen cooking skills intervention program and might increase participants' adherence to healthy eating habits.

Cooking with alcohol: a matched case-control study in Italy and germany assessing the risk of alcoholism due to an early exposure to alcohol in childhood

The study aims at understanding the role of early exposure to ethanol during childhood, in particular in the form of alcohol used in food preparation. A matched case control study was conducted in Italy and Germany. 300 cases were selected from the lists of the Alcoholics Anonymous Associations and 300 controls were matched from the general population. A CATI system was used for collecting information on drinking habits, family risk factors, age at first ethanol consumption, binge drinking episodes and alcohol ingestion as a food ingredient during childhood. Association of variables with the status of case were analysed using a multivariable conditional logistic regression. In the multivariable model four variables were selected: education, father drinking status, age at first ethanol consumption and binge drinking during adolescence. Consumption of food containing alcohol in common recipes was not associated with an increased risk of alcoholism in older ages. Drinkers having their first contact directly with alcoholic beverage before age 13 were more likely to suffer from alcohol dependence at some time during their life. On the contrary, using alcohol in food preparation during childhood does not appear to be related with subsequent risk for alcohol abuse(AU)

El estudio tiene como objetivo comprender el papel de la exposición temprana al etanol durante la infancia, en particular, la forma en la que se utiliza el alcohol en la preparación de alimentos. Este estudio de emparejamiento de casos y controles se llevó a cabo en Italia y Alemania. Se seleccionaron 300 casos de las listas de las Asociaciones de Alcohólicos Anónimos y se los emparejó con 300 controles obtenidos de la población general. Se utilizó el sistema CATI para la recolección de información sobre hábitos de consumo, factores de riesgo de la familia, edad del primer consumo de etanol, episodios de consumo excesivo de alcohol, e ingesta de alcohol como ingrediente alimentario durante la infancia. Se analizó la asociación de las variables con la situación de cada caso mediante una regresión logística condicional multivariable. En el modelo multivariable se seleccionaron cuatro factores: educación, relación del padre con el alcohol, edad del primer consumo de etanol y episodios de consumo excesivo de alcohol durante la adolescencia. El consumo de alimentos que contienen alcohol en las recetas comunes no se asoció con un mayor riesgo de alcoholismo en edades más avanzadas. Aquellos bebedores que han tenido su primer contacto directo con bebidas alcohólicas antes de los 13 años eran más propensos a sufrir de dependencia al alcohol en algún momento de su vida. Por el contrario, el uso de alcohol en la preparación de alimentos durante la infancia no parece estar relacionado con un riesgo posterior de abuso en el consumo de alcohol(AU)

Diversificación en la preparación de alimentos con énfasis en el balance nutricional utilizando productos del "Programa de Alimentación y Salud Escolar, PASE": en vínculo con el MINED, departamento de La Libertad / Diversification in preparation of food products with emphasis on the nutritional balance using products of the "School Health and Food Program": in asociation with MINED, department of La Libertad

El tema de salud es una línea de investigación, propuesta en la Agenda Nacional de Investigación del Viceministerio de Ciencia y Tecnología. Bajo esa dirección se ha realizado esta investigación, con el interés de proporcionar otras alternativas a los menús que se sirven en los centros escolares a través del "Programa de Alimentación y Salud Escolar", programa que pertenece a la actual política educativa Plan Social Educativo "Vamos a la Escuela"; como su nombre hace referencia esta política tiene un enfoque social, el cual se rige con la línea de equidad, acceso y permanencia al sistema educativo. La vinculación de la alimentación con el programa de huertos escolares permite enriquecer el menú que se sirve de refrigerio en cada uno de los centros educativos, además del beneficio que obtienen las madres colaboradoras, responsables de elaborar los alimentos a través de capacitaciones en la manipulación higiénica y técnicas para hacer los alimentos, considerando las propiedades nutricionales en beneficio de los estudiantes. Con el estudio realizado y los datos recopilados se hacen algunas conclusiones y recomendaciones para los diferentes sectores educativos, y de esta manera hacemos un aporte para que con lo investigado se mejore la aplicación del programa en las instituciones educativas.

The health issue is a line of research, proposed in the National Research Agenda of the Salvadoran Vice Ministry of Science and Technology. Under that direction, this research has been carried out, with the interest of providing other alternatives to the menus that are served in schools through the "School Food and Health Program", a program that belongs to the current educational policy Social Educational Plan " Go to school"; As its name refers to, this policy has a social focus, which is governed by the line of equity, access and permanence in the educational system. The link between food and the school garden program allows enriching the menu that is served as a snack in each of the educational centers, in addition to the benefit obtained by collaborating mothers, responsible for preparing food through training in hygienic handling and techniques for making food, considering the nutritional properties for the benefit of the students. With the study carried out and the data collected, some conclusions and recommendations are made for the different educational sectors, and in this way we make a contribution so that with the research the application of the program in educational institutions is improved.

Factors influencing food preparation behaviours: findings from focus groups with Mexican-American mothers in southern California.

OBJECTIVE: The purpose of the present study was to explore food preparation behaviours, attitudes, meal planning and shopping among Mexican-American mothers. DESIGN: Data were collected through four focus groups with mothers of Mexican origin/ancestry who considered themselves to be the primary food preparer. Topics included food preparation behaviours and influencers (culture, family, attitudes, barriers, meal planning and shopping). Data were analysed using a qualitative grounded theory approach. All focus groups were audio recorded, transcribed verbatim and coded for themes. SETTING: Data were collected in southern California, USA in 2013. SUBJECTS: Of the sample of twenty-one Mexican-American mothers, thirteen were born outside the USA and the mean household size was five members. RESULTS: Participants reported that food was often prepared using traditional staples and food preparation behaviours were learned from maternal family members. Participants also suggested that health was influenced by foods eaten and how they were prepared. Salient factors influencing food preparation behaviours included culture and tradition, maternal family members' food preparation behaviours, food preparation self-efficacy and attitudes towards healthy eating. Time and busy schedules were cited as barriers. CONCLUSIONS: Future interventions should consider utilizing family-based approaches and teaching culturally relevant food preparation skills, especially to youth, while reinforcing more healthful dietary practices.

ASSESSMENT OF GOOD MANUFACTURING PRATICES IN A MEAL PLANTIN THE CITY OF SÃO PAULO / Avaliação das boas práticas de fabricação em uma unidade produtora de refeições da cidade de São Paulo

This work aimed to evaluate good manufacturing practices and the physical facilities of a Meal Producing Plant (UPR), located in the southern area of the city of São Paulo, which produces an average of 1000 meals/day. Conformities and unconformities were determined through application of the "Roadmap for inspection of good practices in commercial food establishments and food services" of the Health Surveillance Center State Ordinance, CVS/2013. It was possible to identify several unconformity issues and the necessity to adjust both the physical plant and determination of routines and processes in meal production. 

Este trabalho teve como objetivo avaliar as Boas Práticas de Fabricação e estrutura física de uma Unidade Produtora de Refeições (UPR) situada na zona sul, da cidade de São Paulo, SP, que produzia em média 1000 refeições/dia, identificando conformidades e não-conformidades através da aplicação do Roteiro de Inspeção das Boas Práticas em estabelecimentos comercias de alimentos e de serviços de alimentação da Portaria Estadual, CVS/2013, do Centro de Vigilância Sanitária. O resultado demonstrou diversos pontos não conformes. Durante o estudo foi possível observar diversas necessidades de adequação tanto na estrutura física, quanto na determinação de rotinas e processos envolvidos na produção de alimentos.

A quantitative exposure model simulating human norovirus transmission during preparation of deli sandwiches.

Human noroviruses (HuNoVs) are a major cause of food borne gastroenteritis worldwide. They are often transmitted via infected and shedding food handlers manipulating foods such as deli sandwiches. The presented study aimed to simulate HuNoV transmission during the preparation of deli sandwiches in a sandwich bar. A quantitative exposure model was developed by combining the GoldSim® and @Risk® software packages. Input data were collected from scientific literature and from a two week observational study performed at two sandwich bars. The model included three food handlers working during a three hour shift on a shared working surface where deli sandwiches are prepared. The model consisted of three components. The first component simulated the preparation of the deli sandwiches and contained the HuNoV reservoirs, locations within the model allowing the accumulation of NoV and the working of intervention measures. The second component covered the contamination sources being (1) the initial HuNoV contaminated lettuce used on the sandwiches and (2) HuNoV originating from a shedding food handler. The third component included four possible intervention measures to reduce HuNoV transmission: hand and surface disinfection during preparation of the sandwiches, hand gloving and hand washing after a restroom visit. A single HuNoV shedding food handler could cause mean levels of 43±18, 81±37 and 18±7 HuNoV particles present on the deli sandwiches, hands and working surfaces, respectively. Introduction of contaminated lettuce as the only source of HuNoV resulted in the presence of 6.4±0.8 and 4.3±0.4 HuNoV on the food and hand reservoirs. The inclusion of hand and surface disinfection and hand gloving as a single intervention measure was not effective in the model as only marginal reductions of HuNoV levels were noticeable in the different reservoirs. High compliance of hand washing after a restroom visit did reduce HuNoV presence substantially on all reservoirs. The model showed that good handling practices such as washing hands after a restroom visit, hand gloving, hand disinfection and surface disinfection in deli sandwich bars were an effective way to prevent HuNoV contamination of the prepared foods, but it also demonstrated that further research is needed to ensure a better assessment of the risk of HuNoV transmission during preparation of foods.

Alimento para fins especiais: ingredientes, elaboração e aglomeração / Food for special needs: ingredients, development and agglomeration

OBJETIVO: Desenvolver uma dieta enteral nutricionalmente completa, com condições ajustadas de aglomeração, visando contemplar as características físicas e químicas desejadas para esse alimento especial. MÉTODOS: Como ingredientes foram utilizados maltodextrina, óleo de canola, triglicerídios de cadeia média, goma acácia, inulina e frutooligossacarídeos, proteínas do soro de leite, isolado proteico de soja, vitaminas e minerais. Após os ajustes das quantidades e proporções dos ingredientes, a formulação foi aglomerada e submetida às análises de composição centesimal, molhabilidade, densidade aparente, atividade de água, viscosidade e cor. RESULTADOS: Obteve-se uma fórmula contendo 1kcal.mL-1, normoproteica (3,9g.100mL-1) e normolipídica (3,9g.100mL-1). Após a aglomeração da dieta, observaram-se os seguintes resultados: molhabilidade de 0,262g.s-1, densidade aparente de 0,317g.cm-3e atividade de água de 0,393. A análise de cor indicou redução da luminosidade e aumento dos parâmetros de cor a*e b*, apresentando leve variação para o vermelho e forte presença do amarelo. CONCLUSÃO: Os ingredientes empregados, e suas respectivas proporções, bem como o processo de aglomeração, possibilitaram a obtenção de um alimento para fins especiais com propriedades bioativas. O processo de aglomeração possibilitou uma dieta de fácil reconstituição e utilização através de sondas, facilitando a infusão e, consequentemente, a diminuição de intercorrências.

OBJECTIVE: This study aimed to develop a nutritionally complete enteral diet, with adjusted agglomeration conditions, and determine the physical and chemical characteristics required by this special food. METHODS: The ingredients were maltodextrin, canola oil, medium-chain triglycerides, acacia gum, inulin, fructooligosaccharides, milk whey protein, soy protein isolate, vitamins and minerals. After the quantities and proportions of the ingredients were adjusted, the formula was agglomerated and analyzed for percent composition, moisture, apparent density, water activity, viscosity and color. RESULTS: The resulting diet contained 1Kcal.mL-1and normal protein (3.9g.100mL-1) and fat (3.9g.100mL-1) levels. After agglomeration, the following results were obtained: moisture 0.262g.s-1, apparent density 0,317g.cm-3and water activity 0.393. Color analysis indicated a decrease in luminosity and increase in a*and b*colors, presenting a slight variation towards red and a strong presence of yellow. CONCLUSION: The used ingredients and respective proportions, as well as the agglomeration process, resulted in a food for special needs with bioactive properties. The agglomeration process produced a diet that can easily be reconstituted and fed through catheters, facilitating infusion and consequently, reducing intercurrences.
