ABSTRACT

The increase in life expectancy can be a consequence of the world's socioeconomic, sanitary and nutritional conditions. Some studies have demonstrated that individuals with a satisfactory diet variety score present a lower risk of malnutrition and better health status. Zinc and selenium are important micronutrients that play a role in many biochemical and physiological processes of the immune system. Deficient individuals can present both innate and adaptive immunity abnormalities and increased susceptibility to infections. Primary immunodeficiency diseases, also known as inborn errors of immunity, are genetic disorders classically characterized by an increased susceptibility to infection and/or dysregulation of a specific immunologic pathway. IgA deficiency (IgAD) is the most common primary antibody deficiency. This disease is defined as serum IgA levels lower than 7 mg/dL and normal IgG and IgM levels in individuals older than four years. Although many patients are asymptomatic, selected patients suffer from different clinical complications, such as pulmonary infections, allergies, autoimmune diseases, gastrointestinal disorders and malignancy. Knowing the nutritional status as well as the risk of zinc and selenium deficiency could be helpful for the management of IgAD patients. OBJECTIVES: to investigate the anthropometric, biochemical, and nutritional profiles and the status of zinc and selenium in patients with IgAD. METHODS: in this descriptive study, we screened 16 IgAD patients for anthropometric and dietary data, biochemical evaluation and determination of plasma and erythrocyte levels of zinc and selenium. RESULTS: dietary intake of zinc and selenium was adequate in 75% and 86% of the patients, respectively. These results were consistent with the plasma levels (adequate levels of zinc in all patients and selenium in 50% of children, 25% of adolescents and 100% of adults). However, erythrocyte levels were low for both micronutrients (deficiency for both in 100% of children, 75% of adolescents and 25% of adults). CONCLUSION: our results highlight the elevated prevalence of erythrocyte zinc and selenium deficiency in patients with IgAD, and the need for investigation of these micronutrients in their follow-up.

ABSTRACT

Resumo A alimentação adequada tem profundo impacto na saúde dos idosos, e uma especial atenção deve ser dada ao consumo de açúcares de adição na dieta, que em excesso está associado a pior controle das doenças crônicas nesta fase. O objetivo do estudo foi avaliar a prevalência do consumo de açúcares de adição de idosos da região de Campinas-SP, seus fatores associados e suas principais fontes alimentares. Trata-se de estudo transversal realizado na região de Campinas-SP, com amostra de conveniência de 586 idosos. O consumo foi obtido por meio de dois recordatórios de 24 horas, sendo inadequado se >5% do consumo energético total. Também foi calculada a contribuição dos alimentos em relação ao teor total de açúcares. Considerou-se nível crítico de p<0,05. O consumo médio de açúcares de adição estava acima do recomendado (7,0%), inadequado em mais da metade da população estudada, sendo o açúcar de mesa e o mel as principais fontes dietéticas. A prevalência de inadequação do consumo foi maior entre mulheres (69,8%; p=0,004) e em indivíduos com baixo peso (83,7%; p=0,014), e o consumo foi menor em portadores de diabetes (47,8%; p<0,001). Os resultados apontam para que sejam elaboradas ações de saúde e nutrição a fim de garantir um consumo adequado de açúcares nesta fase.


Abstract Adequate nutrition has a profound impact on older adults' health. Therefore, special attention should be given to the dietetic intake of added sugars, which in excess is associated with poorer control of chronic diseases in this phase. The aim of the study was to evaluate the prevalence of consumption of added sugars in older adults in the Campinas-SP region, its associated factors, and its main dietary sources. A cross-sectional study was conducted in the region of Campinas-SP, with a convenience sample of 586 older individuals. Intake was obtained using two 24-hour food recalls, and values >5% of total energy consumption were considered inadequate. The contribution of the groups and foods in relation to the total content of sugars was also calculated. A critical level of p<0.05 was considered. The average intake of added sugars was higher than recommended (7.0%), and this inadequacy was observed in more than half of the sample, being table sugar and honey the main dietary sources. The prevalence of inadequate consumption was higher among women (69.8%; p=0.004) and individuals with low weight (83.7%; p=0.014), and lower in those with diabetes (47.8%; p<0.001). Results indicate that health and nutrition actions should be developed to ensure adequate sugar intake at this stage.

ABSTRACT

ABSTRACT Objective: Analyze the content of the main messages of the world food guides, identifying the approach regarding the food processing level. Methods: This qualitative exploratory study was conducted through documentary research based on analyzing the main messages of 96 consumption guides selected from the database provided by the Food and Agriculture Organization of the United Nations. The unit of analysis consisted of segments of the main messages whose content was scrutinized using the document analysis technique. Recommendations that referred to food processing were identified after repeated readings. Data were extracted according to the developed protocol, including terms used, consumption guidance, scope of approach, and complementary information (definition, justification, exemplification, and advice on the recommended consumption amount). Results: We identified 21 Food Guides (21.88%) with recommendations related to the food processing level in their main messages, primarily published after 2012 (76.19%). The analyzed guides used terms "highly processed", "ultra-processed", "processed", "minimally processed", and "non-processed". Guidelines regarding limiting consumption were primarily used by the guides, and few specified the related food. The messages did not define the terms used. When identified, the justifications were of a nutritional or health nature. Conclusion: We observed a lack of agreement and standardization concerning the terms used, the guidelines for consumption, and the scope of the identified recommendations, with little or no additional information to explain or justify the approach adopted regarding the food processing level.


RESUMO Objetivo: Analisar o conteúdo das mensagens principais dos guias alimentares mundiais identificando a abordagem quanto ao nível de processamento dos alimentos. Métodos: Estudo exploratório qualitativo, realizado por meio de pesquisa documental, com base na análise das mensagens principais de 96 guias alimentares selecionadas no banco de dados disponibilizado pela Food and Agriculture Organization of the United Nations. A unidade de análise consistiu em segmentos das mensagens principais cujo conteúdo foi analisado através da técnica de análise documental. Após repetidas leituras foram identificadas as recomendações que faziam referência ao processamento dos alimentos. Os dados foram extraídos segundo protocolo desenvolvido, contemplando: termos utilizados; orientação de consumo; abrangência da abordagem; presença de informações complementares (definição; justificativa; exemplificação; e orientação sobre quantidade recomendada de consumo). Resultados: Constatou-se que 21 guias alimentares (21,88%) faziam recomendações relacionadas ao nível de processamento do alimento em suas mensagens principais, a maioria (76,19%) publicado após 2012. Os guias analisados utilizaram os termos: altamente processado, ultraprocessado, processado, minimamente processado e não processado. Orientações referentes à limitação de consumo foram as mais utilizadas pelos guias e poucos especificavam o alimento relacionado. As mensagens não apresentavam definição para os termos utilizados. Quando presentes, as justificativas eram de cunho nutricional ou de saúde. Conclusão: Foi observada falta de consenso e padronização no que se refere aos termos utilizados, às orientações de consumo e à abrangência das recomendações apresentadas, além de pouca ou nenhuma informação complementar capaz de explicar ou justificar a abordagem realizada em relação ao nível de processamento dos alimentos.

ABSTRACT

RESUMEN Introducción: Uno de los factores que influyen en la desnutrición hospitalaria es la incapacidad del paciente para alimentarse correctamente. Un bajo consumo de la dieta hospitalaria aumenta el riesgo a sufrir complicaciones de salud, además genera impacto económico y ambiental, producto del aumento de desperdicio de alimentos. Generar estrategias encaminadas a mitigar este problema debe ser prioridad para el sector salud. Objetivo: Identificar herramientas técnicas utilizadas para medir el consumo y/o desperdicio de alimentos en la dieta hospitalaria. Materiales y métodos: Búsqueda sistemática de estudios publicados en las bases de datos de EMBASE y MEDLINE a través de la plataforma Pubmed, en febrero del 2019, temporalidad 20 años. Se buscaron por términos controlados sobre dieta hospitalaria, desperdicio de alimentos y la satisfacción del paciente. Resultados: Se encontraron 410 artículos en inglés, español y portugués. Se seleccionaron 21 artículos para análisis de texto completo por cumplimiento de criterios de selección. Conclusiones: Las herramientas encontradas para la medición del desperdicio de alimentos se basaron principalmente en el pesaje, y la medición visual ya sea directa o por imágenes; otras aproximaciones incluyeron cuestionarios y métodos de múltiples componentes, la mayoría sin hacer discriminación del componente alimenticio desperdiciado.


ABSTRACT Introduction: One of the factors that influences hospital malnutrition is the inability of the patient to eat properly. A low consumption of the hospital diet increases the risk of suffering health complications, in addition to generating an economic and environmental impact, as a result of the increase in food waste. Generating strategies aimed at mitigating this problem should be a priority for the health sector. Objective: Identify technical tools used to measure food consumption and / or waste in the hospital diet. Materials and methods: Systematic search for studies published in the EMBASE and MEDLINE databases through the Pubmed platform was conducted in February 2019, searching articles published in the last 20 years. We searched for controlled terms on hospital diet, food waste, and patient satisfaction. Results: 410 articles were found in English, Spanish and Portuguese. Twenty-one articles were selected for full-text analysis by meeting the selection criteria. Conclusions: The tools found for the measurement of food consumption were based mainly on weighing, and visual measurement either direct or by images; other approaches included questionnaires and multi-component methods, most of the tools did not discriminate the food component wasted.

ABSTRACT

Introdução: A análise da ingestão alimentar de pacientes com doença renal crônica (DRC) em tratamento dialítico é eficaz para fornecer informações a fim de auxiliar no diagnóstico nutricional e nortear as condutas dietéticas necessárias. Objetivo: Analisar a adequação do consumo alimentar de acordo com as recomendações publicadas pelo Kidney Disease Outcome Quality Initiative (KDOQI) para macro e micronutrientes, além de avaliar a capacidade antioxidante total da dieta (CATd), de portadores de DRC. Materiais e Métodos: Estudo transversal, com 60 voluntários portadores de DRC em tratamento hemodialítico de um Hospital Universitário de Juiz de Fora ­ MG. A caracterização da amostra foi feita no período de junho de 2019 a fevereiro de 2020, através da aplicação de um Questionário Quantitativo de Frequência Alimentar (QQFA) e de coleta de dados pessoais, clínicos e comorbidades. As análises estatísticas foram conduzidas utilizando-se o software SPSS, versão 20.0. As variáveis numéricas foram apresentadas na forma de média (± desvio-padrão), mediana, mínimo e máximo, enquanto as categóricas em frequência absoluta e relativa. Resultados: Observou-se que 43% e 55% dos pacientes apresentaram um consumo calórico e proteico acima do preconizado pela KDOQI, respectivamente. Para os micronutrientes, foi observado que 77% dos pacientes apresentaram consumo de cálcio abaixo do recomendado e de fósforo 65% maior do que a recomendação atual. Percebeu-se que 67% e 40% dos pacientes apresentaram adequado consumo de sódio e potássio. O perfil lipídico da dieta dos pacientes, demonstrou uma desproporção da razão ômega 6/ômega 3, além de um CATd de 4,05 mmol/dia. Conclusão: Através do presente estudo podemos concluir que o consumo alimentar dos pacientes em hemodiálise avaliados apresenta algumas inadequações em relação às recomendações propostas pela literatura.


Introduction: The analysis of food intake in patients with chronic kidney disease (CKD) undergoing dialysis is effective to provide information to assist in nutritional diagnosis and guide the necessary dietary behaviors. Objective: To analyze the adequacy of food consumption according to the recommendations published by the Kidney Disease Outcome Quality Initiative (KDOQI) for macro and micronutrients, in addition to evaluating the total antioxidant capacity of the diet (CATd) of patients with CKD. Materials and Methods: Cross-sectional study with 60 volunteers with CKD undergoing hemodialysis treatment at a University Hospital in Juiz de Fora ­ MG. The characterization of the sample was carried out from June 2019 to February 2020, through the application of a Quantitative Food Frequency Questionnaire (QQFA) and the collection of personal, clinical and comorbid data. Statistical analyzes were conducted using SPSS software, version 20.0. Numerical variables were presented as mean (± standard deviation), median, minimum and maximum, while categorical variables in absolute and relative frequency. Results: It was observed that 43% and 55% of the patients had a caloric and protein consumption above that recommended by the KDOQI, respectively. For micronutrients, it was observed that 77% of the patients had calcium intake below the recommended level and phosphorus consumption 65% higher than the current recommendation. It was noticed that 67% and 40% of the patients had adequate consumption of sodium and potassium. The lipid profile of the patients' diet showed a disproportion of the omega 6/omega 3 ratio, in addition to a CATd of 4.05 mmol/day. Conclusion: Through the present study we can conclude that the food consumption of the evaluated hemodialysis patients presents some inadequacies in relation to the recommendations proposed by the literature

ABSTRACT

RESUMEN Objetivos. Determinar el efecto genotóxico de la tartrazina en linfocitos de sangre periférica de Mus musculus BALB/c. Materiales y métodos. Se realizó un estudio experimental, a través de cinco grupos, con cinco ratones en cada uno. Se les registró el peso durante 17 semanas y, en la semana 15 se les administró suero fisiológico (control negativo), dicromato de potasio 25 mg/kg de peso corporal (pc) (control positivo) y tartrazina a dosis de 0,75 mg/kg pc, 7,5 mg/kg pc y 75 mg/kg pc, durante siete días, a excepción del control positivo que fue en dosis única. Luego, cada 24 h se obtuvo una muestra de sangre periférica de la cola y se realizó el frotis, secado y coloración. Posteriormente, se realizó el conteo de 1000 linfocitos por muestra de cada ratón, en todos los tratamientos. Resultados. Los tres tratamientos con tartrazina no causaron diferencias significativas en el peso de ratones a la semana 15, pero sí produjeron diferencias significativas en la frecuencia de linfocitos micronucleados, siendo el tratamiento con tartrazina de 75 mg/kg pc el de mayor efecto genotóxico, induciendo un promedio de 1,63 ± 0,08 linfocitos micronucleados, comparado con el control positivo que generó un promedio de 1,42 ± 0,08 linfocitos micronucleados. Conclusiones. La tartrazina produjo un efecto genotóxico, incrementando el número de linfocitos micronucleados, a dosis de 0,75; 7,5 y 75 mg/kg pc y no afecta el peso corporal durante siete días de administración en M. musculus BALB/c.


ABSTRACT Objectives. To determine the genotoxic effect of tartrazine on peripheral blood lymphocytes of BALB/c Mus musculus. Materials and methods. An experimental study was carried out using five groups, with five mice in each group. Their weight was registered for 17 weeks, and at week 15 they were administered physiological saline solution (negative control), potassium dichromate at 25 mg/kg body weight (bw) (positive control) and tartrazine at doses of 0.75 mg/kg bw, 7.5 mg/kg bw and 75 mg/kg bw, for seven days, with the exception of the positive control which was a single dose. Then, every 24 hours, a peripheral blood sample was obtained from the tail, which was then smeared, dried and stained. Subsequently, 1000 lymphocytes were counted for each sample from each mouse, for all treatment groups. Results. The three tartrazine treatments did not cause significant differences in the weight of mice at week 15, but did produce significant differences in the frequency of micronucleated lymphocytes, with the 75 mg/kg bw tartrazine treatment having the greatest genotoxic effect, inducing an average of 1.63 ± 0.08 micronucleated lymphocytes, compared to the positive control which obtained an average of 1.42 ± 0.08 micronucleated lymphocytes. Conclusions. Tartrazine produced a genotoxic effect, increasing the number of micronucleated lymphocytes, at doses of 0.75; 7.5 and 75 mg/kg bw and did not affect body weight during seven days of administration to BALB/c M. musculus.

ABSTRACT

O Diabetes Mellitus (DM) afeta cerca de 400 milhões de pessoas em todo o mundo. É de senso comum que esses indivíduos devem priorizar o consumo de alimentos minimamente processados e in natura. No entanto, o consumo racional de alimentos processados torna-se um desafio devido ao estilo de vida ocidental e a alta oferta desses produtos, incluindo aqueles específicos para pacientes diabéticos. Esse trabalho visa verificar a adequação dos rótulos de alimentos dietéticos industrializados. Avaliou-se rótulos de biscoitos, doces e pães destinados para diabéticos, disponíveis em supermercados, lojas de produtos naturais e lojas de suplementos alimentares. Além das informações nutricionais, foi avaliada a adequação da rotulagem segundo a Portaria nº 29, de 13 de janeiro de 1998. Foram analisados 98 alimentos, sendo 57 doces, 27 biscoitos e 14 pães. Observamos que há uma grande inadequação desses produtos, bem como falta de informações acerca de importantes nutrientes. É necessária a adequação da rotulagem e a conferência de cada item, e os profissionais de saúde, principalmente os nutricionistas, devem estar atentos ao recomendar esses alimentos aos pacientes.(AU)


Diabetes Mellitus (DM) affects about 400 million people worldwide. It is common knowledge that diabetic individuals should prioritize the consumption of fresh foods or minimally processed foods. However, the rational consumption of processed foods becomes a challenge due to the western lifestyle and the high source of these products, including those specific for diabetic people. This manuscript aims to verify the label adequacy of processed dietary foods. We performed the evaluation of diabetic cookies, candy and bread labels available at supermarkets, health food stores and food supplement stores. The adequacy of the nutritional items, and the labeling was evaluated according the Brazilian current legislation. A total of 98 items were analyzed: 57 candies, 27 cookies and 14 breads. We observed that there was a great inadequacy of these products, as well as a lack of information about important nutrients. It is necessary to adapt the labeling and to perform the conference of each item, and the health professionals, especially the nutritionists, must pay close attention before recommending these foods to their patients.(AU)

ABSTRACT

O presente estudo objetivou avaliar a adequação da composição nutricional dos cardápios dos Centros Municipais de Educação Infantil (CMEI) de Goiânia aos parâmetros propostos pelo Programa Nacional de Alimentação Escolar (PNAE). A pesquisa consistiu-se na análise da composição nutricional dos cardápios, ofertados por um período de onze meses (janeiro a dezembro de 2019), às crianças da faixa etária de 12 meses a três anos de idade, dos 138 CMEI de Goiânia-GO. Para fins de comparação dos valores encontrados foram utilizadas as referências de energia, macronutrientes e micronutrientes do programa, para a faixa etária selecionada. Com base nas recomendações do PNAE, os cardápios foram em média insuficientes em relação à fibra alimentar e com valor muito próximo ao recomendado para o ferro. Por outro lado, para o Magnésio, Vitamina A e Vitamina C as quantidades consumidas, em média, foram de duas a seis vezes maiores que as recomendadas. A partir dos resultados encontrados evidenciou-se a necessidade da oferta de mais frutas e vegetais nos cardápios diários, para que o teor de fibras seja alcançado e favorecer o desenvolvimento nas crianças do hábito de inclui-los em sua alimentação diária, da infância à vida adulta. E assim, garantir o Direito Humano à Alimentação Adequada e, consequentemente, a promoção da saúde. Destaca-se a importância do profissional nutricionista, na elaboração do cardápio, a fim de garantir a adequação da alimentação oferecida em termos qualitativos e quantitativos, evitando carências ou excessos nutricionais, contribuindo, para o crescimento, desenvolvimento e formação de hábitos alimentares saudáveis das crianças.(AU)


This study aimed to evaluate the adequacy of the nutritional composition of the menus of the Municipal Centers for Early Childhood Education (CMEI) of Goiânia to the parameters proposed by the National School Feeding Program (PNAE). The research consisted in the analysis of the nutritional composition of the menus, offered for a period of eleven months (January to December 2019), to children aged 12 months to three years old, of the 138 CMEI of Goiânia-GO. To the purpose of comparing the values found, the references of energy, macronutrients, and micronutrients of the PNAE were used, for the selected age group. Based on the PNAE recommendations, the menu was, on average, insufficient in relation to dietary fiber and with a value close to that recommended for iron. On the other hand, for Magnesium, Vitamin A and Vitamin C the amounts consumed, on average, were about two to six times greater than those recommended. From the results found, it is evident the need to offer more fruits and vegetables in the daily menus, so that the fiber content is reached and to favor the development of children in the habit of including them in their daily diet, from childhood life adult. And so, to guarantee the Human Right to Adequate Food and, consequently, health promotion. The importance of the professional nutritionist in the elaboration of the menus is highlighted, to guarantee the adequacy of the food offered in qualitative and quantitative terms, avoiding nutritional deficiencies or excesses, thus contributing to the growth, development and formation of health eating habits of the children.(AU)

ABSTRACT

O Guia Alimentar para a População Brasileira é reconhecido como um potente indutor de políticas públicas de alimentação e nutrição. Nessa perspectiva, este artigo apresenta o percurso metodológico e as evidências que subsidiaram a elaboração dos novos parâmetros de aquisição de alimentos do Programa Nacional de Alimentação Escolar (PNAE). Tal elaboração envolveu as análises de: (1) participação dos recursos federais utilizados para compra de alimentos, agrupados segundo a classificação NOVA, empregada no Guia Alimentar para a População Brasileira, pelo conjunto de municípios brasileiros e segundo classificação da execução (positiva ou negativa); (2) cardápios mensais de referência que foram elaborados seguindo recomendações do Guia Alimentar para a População Brasileira; (3) aquisição de alimentos por amostra de 525 municípios, envolvendo a participação relativa dos grupos de alimentos (segundo a NOVA) no total de gastos e de energia e a qualidade nutricional dos alimentos adquiridos; e (4) alimentos ultraprocessados que não devem ser ofertados no ambiente escolar. Foi proposta a adoção dos seguintes parâmetros para participação dos grupos de alimentos em relação ao total de recursos federais empregados na compra de alimentos: ≥ 75% de recursos para alimentos in natura ou minimamente processados; < 20% para alimentos processados ou ultraprocessados e < 5% para ingredientes culinários processados e a ampliação da lista de alimentos cuja aquisição com recursos federais do PNAE é proibida. Esse processo subsidiou a elaboração da Resolução CD/FNDE nº 6, de 8 de maio de 2020, que dispõe sobre o atendimento da alimentação escolar aos alunos da educação básica no âmbito do PNAE.

Desde esta perspectiva, este artículo presenta la trayectoria metodológica y evidencias que apoyaron la elaboración de los nuevos parámetros de adquisición de alimentos del Programa Nacional de Alimentación Escolar (PNAE). Tal elaboración implicó los análisis de: (1) participación de los recursos federales utilizados para la compra de alimentos, agrupados según la clasificación NOVA, empleada en el Guía Alimentaria para la Población Brasileña, por el conjunto de municipios brasileños, y según la clasificación de la ejecución (positiva o negativa); (2) menús mensuales de referencia que fueron elaborados siguiendo recomendaciones del Guía Alimentaria para la Población Brasileña; (3) adquisición de alimentos mediante una muestra de 525 municipios, implicando la participación relativa de los grupos de alimentos (según NOVA) en el total de gastos y de energía, así como la calidad nutricional de los alimentos adquiridos; y (4) alimentos ultraprocesados que no deben ser ofrecidos en el entorno escolar. Se propuso la adopción de los siguientes parámetros para la participación de los grupos de alimentos, en relación con el total de recursos federales empleados en la compra de alimentos: ≥ 75% de recursos para alimentos in natura o mínimamente procesados; < 20% para alimentos procesados o ultraprocesados, y < 5% para ingredientes culinarios procesados, así como la ampliación de la lista de alimentos, cuya adquisición con recursos federales del PNAE está prohibida. Este proceso apoyó la elaboración de la Resolución CD/FNDE nº 6, del 8 de mayo de 2020, que organiza la atención de la alimentación escolar a alumnos de educación básica en el ámbito del PNAE.


The Dietary Guidelines for the Brazilian Population is acknowledged as a powerful inducer of public food and nutrition policies. In this perspective, this article presents the methodological path and evidence that supported the elaboration of the new parameters of food acquisition of the Brazilian National School Feeding Program (PNAE). This elaboration involved the analyses of: (1) participation of federal resources used to purchase food, grouped according to the NOVA classification, used in Dietary Guidelines for the Brazilian Population, by the set of Brazilian municipalities and according to the classification of the execution (positive or negative); (2) monthly reference menus that were prepared following Dietary Guidelines for the Brazilian Population recommendations; (3) analysis of food acquisition by the sampling of 525 municipalities, involving the relative participation of food groups (according to NOVA) in total expenditures and energy and nutritional quality of purchased foods; and (4) analysis of ultra-processed foods that should not be offered in the school environment. We proposed the adoption of the following parameters for the participation of food groups in relation to the total federal resources used in the purchase of food: ≥ 75% of resources for fresh or minimally processed foods; < 20% for processed or ultra-processed foods and < 5% for processed culinary ingredients, as well as the expansion of the list of foods whose acquisition with federal resources from PNAE is prohibited. This process supported the elaboration of Resolution CD/FNDE n. 6 of May 8, 2020, which provides for the attendance of school feeding to primary education students within the PNAE.

ABSTRACT

Introdução: O Programa Nacional de Alimentação Escolar busca, entre outros objetivos, atender às necessidades nutricionais dos escolares das diferentes modalidades de ensino durante sua permanência em sala de aula. Objetivo: Comparar os valores estimados para adequação do valor calórico total (VCT) dos cardápios da alimentação escolar de um município. Métodos: Foram incluídas no estudo as seis modalidades de ensino do município, e foram analisados 12 cardápios, totalizando 60 dias, através de duas tabelas de composição centesimal de alimentos, a fim de comparar as diferenças existentes nos valores fornecidos por cada uma delas. Os valores encontrados foram comparados com as recomendações por modalidade de ensino e faixa etária da Resolução CD/FNDE nº 26/2013 e categorizados em "adequado", "acima" ou "abaixo" da recomendação. Resultados: Dos dias analisados pela tabela do IBGE, cinco semanas (41,7%) estavam com a média semanal do VCT adequada para o valor preconizado pelo FNDE. A média das semanas restantes ficou acima do recomendado (58,3%). Já de acordo com a TACO, nenhuma média semanal se adequou ao FNDE. Conclusão: A avaliação dos cardápios revelou predominantemente valores calóricos acima daqueles preconizados para a alimentação escolar. Sobressai-se assim a importância do nutricionista na alimentação escolar e, neste caso, na avaliação do programa, que requer respeito à cultura alimentar local, mas também a abordagem da alimentação como estratégia educacional. (AU)


Introduction: The National School Feeding Program seeks, among other goals, to meet the nutritional needs of students of different teaching modalities during their stay in the classroom. Objective: To compare the estimated values for adequacy of the Total Caloric Value (VCT) of the school feeding menus of a municipality. Methods: The six teaching modalities of the municipality were included in the study, and 12 menus were analyzed, totaling 60 days, through two tables of centesimal food composition, in order to compare the differences in the values provided by each one of them. The values found were compared with the recommendations by teaching modality and age group of Resolution CD/FNDE nº 26/2013 and categorized as "adequate", "above" or "below" the recommended values. Results: Of the days analyzed by the IBGE table, five weeks (41.7%) were with the appropriate weekly VCT average for the value recommended by the FNDE. The average of the remaining weeks was above recommended (58,3%). Already according to TACO, no weekly average fit the FNDE. Conclusion: The evaluation of the menus revealed predominantly caloric values above those recommended for school feeding. Within this, the importance of the nutritionist in school feeding stands out and, in this case, in the evaluation of the program, which requires respect for the local food culture, but also the approach of food as an educational strategy.

ABSTRACT

Magnesium is a predominantly intracellular ion and plays an important role in energy metabolism and in the maintenance of energy homeostasis. This study aimed to estimate the dietary intake of magnesium and its association with adiposity parameters in obese women. This cross-sectional study included 125 women, aged between 20 and 50 years, who were divided into two groups: obese group (n = 62) and control group (n = 63). The control group was age-matched. Adiposity parameters determined were weight, body mass index and waist circumference as well as the intake of calories, macronutrients, and magnesium were calculated. The cut-off for obesity was body mass index between 30.0 and 39.9 kg/m2 and for control group was between 18.5 and 24.9 kg/m2 Food intake was calculated using 3-day food records, and energy consumption as well as the intake of macronutrients and magnesium was calculated using the NutWin software version 1.5. The reference values used were the Acceptable Macronutrient Distribution Range for macronutrients and the Estimated Average Requirement (EAR) for magnesium. The average levels of magnesium found in the diet were lower than those recommended (169.1 ± 64.5 mg Mg/day and 158.5 ± 42.9 mg Mg/day, for obese women and control group, respectively) and the differences between the groups were not statistically different (p > 0.05). The correlation analysis indicated that the association between the dietary intake of magnesium and adiposity was not significant. The results of this study indicate that dietary magnesium does not influence the adiposity parameters in obese women.

ABSTRACT

Consumed by populations in South America, Araucaria angustifolia seeds have received little study regarding elemental composition and nutritional value. Thirty-five seed sites from subtropical Brazil were sampled and seed concentrations of C, N, K, Ca, Mg, P, Fe, Zn, Mn, Cu, Mo, Ni, Co, Cr, Ba, and Cd were determined. The highest concentration of N was observed in samples from regions with Cfa climate (humid subtropical, oceanic climate, without dry season with hot summer) and igneous rock, which was superior to regions with Cfb climate (humid subtropical, oceanic climate, without dry season with temperate summer) and metamorphic rock. Seeds can be a source of nutrients: K (11.8 g kg-1), P (4.1 g kg-1), Mn (9.1 mg kg-1), Cu (7.2 mg kg-1), Mo (0.93 mg kg-1), and Cr (0.65 mg kg-1). Values for Ba (0.93 mg kg-1) and Cd (0.19 mg kg-1) indicated no risk to human health. This study expands knowledge regarding the elemental composition of A. angustifolia. Results indicate that these seeds have nutritional value, and their consumption can be a good strategy to improve overall human nutrition in this region of South America.

ABSTRACT

O objetivo do presente trabalho foi analisar as práticas de aleitamento materno e alimentação complementar em menores de dois anos, bem como o padrão de consumo de açúcar e bebidas adoçadas. Foi realizado um estudo transversal realizado com 82 crianças internadas no Hospital Nossa Senhora da Conceição de Tubarão no período de Fevereiro a Agosto de 2016. Aplicou-se um questionário levando em conta dados do nascimento da criança, bem como realização e modo de realização de aleitamento materno e alimentação complementar e também características maternas. Observou-se que 72% das crianças mamaram na primeira hora após o nascimento, mas apenas 42,7% realizaram aleitamento materno exclusivo (AME) por algum período, sendo a mediana do AME de 30 dias. A idade média do inicio da alimentação complementar foi de 5,88 meses. Pode-se observar também que 12,5% das crianças com 0 a 5 meses ingeriram leite adoçado e 30,8% das crianças com 12 a 17 meses ingeriram refrigerante. Os resultados sugerem baixas taxas de AME e início precoce da alimentação complementar e consumo de açúcar.


The objective of the present study was to analyze the practices of breastfeeding and complementary feeding in children under the age of two, as well as the pattern of consumption of sugar and sweetened beverages. A cross-sectional study was carried out with 82 children hospitalized at the Hospital Nossa Senhora da Conceição de Tubarão from February to August 2016. A questionnaire was conducted comprising questions about children's birth, breastefeeding and complementary feeding, as wll as maternal characteristics. 72% of the children were breastfed within the first hour after birth, but only 42.7% had exclusive breastfeeding for some period, the median being 30 days. The averange age of complementary feeding initiation was 5.88 months. Moreover, 12.5% of the children aged 0-5 months ingested sweetened milk and 30.8% of the children aged 12- 17 months ingested soda. The results suggest low rates of exclusive breastfeeding and early onset of complementary feeding and sugar consumption.

ABSTRACT

ABSTRACT Objective To analyse the nutritional status of the adult population in Esmeraldas by means of anthropometric measurements, the input of macro and micronutrients in the diet, and the adequacy estimation of nutrient intake by hispanic Dietary Reference Instakes along with the sex and the age influence. Methods Nutrient intake data were obtained by personal interview with the application of two 24 hour recalls (weekend and weekday). The anthropometric indicators analysed were body mass index, waist circumference and blood pressure. Nutriplato version 2.0 software was used for the two 24-hours food recall surveys data processing, and for the respective calculations of macronutrients, micronutrients and Dietary Reference Intakes. Means and standard deviations were calculated for anthropometry, nutrient intakes and Dietary Reference Instakes. The General Linear Model was applied to identify differences in relation to nutrient intakes considering sex, profession, body mass index, group, origin and day of the week as factors. Results Statistical analysis showed significant differences mainly in carbohydrates, fiber, calcium, phosphorus, iron, sodium, iodine, and vitamin E. Dietary intakes were compared with the Federación Española de Sociedades de Nutrición, Alimentación y Dietética Dietary Reference Intakes requirements and calcium, potassium, iodine, riboflavin, pantothenic acid, biotin, vitamin D, vitamin E, fiber, monounsaturated fatty acids and polyunsaturated fatty acids are below the Dietary Reference Instakes in all ages and gender subgroups. The anthropometric results obtained indicated that 67.0% of the population were overweight and obese, the 87.7% of the adults suffered from prehypertension and the waist circumference indicated that 73.0% of the subjects were established in the range of high risk of cardiovascular disease. Conclusion Priority nutrition actions and interventions are needed to be developed in Esmeraldas adult population.


RESUMO Objetivo Analisar o estado nutricional da população adulta de Esmeraldas utilizando medições antropométricas, o aporte dietético de macro e micronutrientes, e a estimação da adequação da ingestão de nutrientes por ingestão diária de referência hispânicos, juntamente com sexo e idade. Métodos Os dados de ingestão de nutrientes foram obtidos através de uma entrevista pessoal com a aplicação de dois lembretes de 24 horas (o fim de semana e o dia da semana). Os indicadores antropométricos analisados foram índice de massa corporal, circunferência da cintura e pressão arterial. O software Nutriplato versão 2.0 para o processamento dos dados obtidos com os dois lembretes de alimentos 24 horas e para os cálculos respectivos de macronutrientes, micronutrientes e ingestão diária de referência. As medias e desvios-padrão foram calculados para antropometria, ingestão de nutrientes e ingestão diária de referência. O General Linear Model foi aplicado para identificar diferenças na ingestão de nutrientes levando em consideração gênero, profissão, índice de massa corporal, grupo, origem e dia da semana como fatores. Resultados A análise estatística mostrou diferenças significativas principalmente em carboidratos, fibras, cálcio, fósforo, ferro, sódio, iodo e vitamina E. As ingestões dietéticas foram comparadas com a Ingestão Diária de Referência de Federación Española de Sociedades de Nutrición, Alimentación y Dietética e para todos os subgrupos e todas as idades não foram alcançadas a referência dietética para cálcio, potássio, iodo, riboflavina, ácido pantatênico, biotina, vitamina D, vitamina E, fibra e ácidos graxos monoinsaturados e poliinsaturados. Os resultados antropométricos obtidos indicaram que 67.0% da população estava com sobrepeso e obesidade, 87.7% dos adultos sofriam de pré-hipertensão e a circunferência da cintura indicou que 73.0% dos indivíduos apresentavam risco de doença cardiovascular. Conclusão Conclui-se que precisam de ações e intervenções prioritárias em nutrição para aplicá-las na população adulta de Esmeraldas.

ABSTRACT

Introdução: A hemodiálise é um tratamento comumente realizado em pacientes que apresentam perda da função renal, com o intuito de liberar resíduos prejudiciais à saúde do corpo. Esta terapêutica ocasiona perdas de nutrientes do sangue, sendo, dessa forma, contribuinte para a desnutrição, o que reforça o papel da nutrição como tratamento coadjuvante.A análise da ingestão alimentar é capaz de fornecer informações para nortear as condutas dietéticas,portanto, este estudo objetivou verificar a adequabilidade da ingestão nutricional com as recomendações nutricionais específicas e sua relação com o estado nutricional de pacientes submetidos a tratamento hemodialítico em uma clínica do município de Vitória da Conquista, BA. Método: A avaliação da ingestão nutricional foi procedida determinando a ingestão proteica por quilo de peso, de quilocalorias por quilo de peso, cálcio, ferro, potássio e fósforo,comparando-as com as recomendações específicas. O estado nutricional foi determinado por meio da Avaliação Subjetiva Global modificada. Resultados: Um total de 122 pacientes foram incluídos no estudo, estando a maioria em risco nutricional e nenhum com desnutrição gravíssima. A maioria também apresentou inadequação quanto à ingestão de calorias e dos nutrientes avaliados. Não foram encontradas correlações entre a ingestão calórica vs. estado nutricional e ingestão proteica vs. estado nutricional, mas analisando a ingestão calórica e proteica foi observada forte correlação (r=0,799). Conclusão: As ingestões de proteínas, quilocalorias, cálcio, ferro, potássio e fósforo apresentaram-se inadequadas na população estudada, o que pode influenciar o estado clínico e nutricional destes pacientes.(AU)


Introduction: Hemodialysis is a treatment commonly performed in patients who had loss of kidney function, in order to release harmful waste to body's health. This therapy causes loss of nutrients from the blood, and thus contributes to malnutrition, which reinforces the role of nutrition as adjuvant treatment. Analysis of food intake is able to provide information to guide dietetic conducts, so this study aimed to verify the nutritional intake adequacy with specific nutritional recommendations and their relation with the nutritional status of patients undergoing hemodialysis treatment at a clinic in the city of Vitória da Conquista, BA. Method: The assessment of nutritional intake was done determining the protein intake per kilogram of weight, kilocalories per kilogram of weight, calcium, iron, potassium and phosphorus comparing it to the specific recommendations. Nutritional status was determined using the Subjective Global Assessment modified. Results: A total of 122 patients were included in the study, with the majority in nutritional risk and none had very serious malnutrition. Similarly, most also had impairments as to intake of calories and nutrients evaluated. No correlations were found between calorie intake vs. nutritional status and protein intake vs. nutritional status, but in the analyse caloric and protein intake was found strong correlation (r=0.799). Conclusion: The intake of protein, kilocalories, calcium, iron, potassium and phosphorus showed to be inadequate in the study population, which may influence the clinical and nutritional status of these patients.(AU)

ABSTRACT

RESUMO Objetivos: Determinar a concentração de alfa-tocoferol no leite materno em diferentes períodos de lactação e estimar o provável fornecimento de vitamina E ao lactente. Métodos: Estudo longitudinal observacional realizado com 100 puérperas atendidas para o parto no Hospital Universitário Ana Bezerra (HUAB) da Universidade Federal do Rio Grande do Norte (UFRN), em Santa Cruz (RN). Foram coletados leite colostro (n=100), leite de transição (n=77) e leite maduro (n=63) no seguimento da lactação. O alfa-tocoferol foi analisado por cromatografia líquida de alta eficiência. O fornecimento de vitamina E para o neonato foi estimado comparando-se o requerimento nutricional de vitamina E (4 mg/dia) com a ingestão diária de leite. Resultados: A concentração média de alfa-tocoferol encontrada nos leites colostro, de transição e maduro foi 40,5±15,0 µmol/L, 13,9±5,2 µmol/L e 8,0±3,8 µmol/L, respectivamente (p<0,001). A possível ingestão desses leites pelo lactente forneceu 6,2 mg/dia de vitamina E no colostro, 4,7 mg/dia no de transição e 2,7 mg/dia no maduro (p<0,0001), evidenciando que apenas o último não garantiu a quantidade recomendada dessa vitamina. Conclusões: Os níveis de alfa-tocoferol no leite diminuíram com a progressão da lactação, e a provável ingestão dos leites colostro e de transição conseguiu atender ao requerimento nutricional do lactente. O leite maduro pode fornecer menores quantidades da vitamina E, o que torna importante o estudo dos fatores que se associam a esses baixos níveis.


ABSTRACT Objectives: To determine the alpha-tocopherol concentration in breast milk at different periods of lactation and to estimate the possible supply of vitamin E to the infant. Methods: A longitudinal observational study was carried out with 100 mothers at University Hospital Ana Bezerra (HUAB), at Universidade Federal do Rio Grande do Norte, in Santa Cruz (RN), Northeast Brazil. Samples of colostrum (n=100), transitional milk (n=77), and mature milk (n=63) were collected. Alpha-tocopherol was analyzed by high-performance liquid chromatography. Vitamin supply to the newborn was estimated by comparing the nutritional requirement of vitamin E (4 mg/day) with the potential daily intake of milk. Results: The mean alpha-tocopherol concentration found in colostrum, transitional, and mature milk was 40.5±15.0 µmol/L, 13.9±5.2 µmol/L, and 8.0±3.8 µmol/L, respectively (p<0.001). The possible effect of these milks offered to the infant 6.2 mg/day of vitamin E in colostrum, 4.7 mg/day in transitional milk, and 2.7 mg/day in mature milk (p<0.0001), shows that only the mature milk did not guarantee the recommended quantity of this vitamin. Conclusions: Alpha-tocopherol levels in human milk decrease through the progression of lactation, and the possible intake of colostrum and transitional milk met the nutritional requirement of the infant. Mature milk may provide smaller amounts of vitamin E. Thus, it is important to study the factors that are associated with such low levels.

ABSTRACT

Micronutrients are important for the prevention of degenerative diseases due to their role in maintaining genomic stability. Therefore, there is international concern about the need to redefine the optimal mineral and vitamin requirements to prevent DNA damage. We analyzed the cytostatic, cytotoxic, and genotoxic effect of in vitro zinc supplementation to determine the effects of zinc deficiency and excess and whether the upper estimate of the physiological requirement recommended for children is safe. To achieve zinc deficiency, DMEM/Ham's F12 medium (HF12) was chelated (HF12Q). Lymphocytes were isolated from healthy female donors (age range, 5-10 yr) and cultured for 7 d as follows: negative control (HF12, 60 µg/dl ZnSO4); deficient (HF12Q, 12 µg/dl ZnSO4); lower level (HF12Q + 80 µg/dl ZnSO4); average level (HF12Q + 180 µg/dl ZnSO4); upper limit (HF12Q + 280 µg/dl ZnSO4); and excess (HF12Q + 380 µg/dl ZnSO4). The comet (quantitative analysis) and cytokinesis-block micronucleus cytome assays were used. Differences were evaluated with Kruskal-Wallis and ANOVA (p < 0.05). Olive tail moment, tail length, micronuclei frequency, and apoptotic and necrotic percentages were significantly higher in the deficient, upper limit, and excess cultures compared with the negative control, lower, and average limit ones. In vitro zinc supplementation at the lower and average limit (80 and 180 µg/dl ZnSO4) of the physiological requirement recommended for children proved to be the most beneficial in avoiding genomic instability, whereas the deficient, upper limit, and excess (12, 280, and 380 µg/dl) cultures increased DNA and chromosomal damage and apoptotic and necrotic frequencies.
