RESUMO

There is a research gap in understanding the relationship between nutrient deficiency and food insecurity among adolescent girls in Afghanistan. The objective of this study was to investigate the associations between nutrient deficiencies and food insecurity among middle and high school-aged girls in Kabul. We conducted a cross-sectional study of 380 randomly selected 11-18-year-old girls attending public schools in grades 6-12. We assessed girls' food insecurity, food and nutrient intake, socioeconomic status, and physical activity. Nutrient consumption was calculated using Nutritionist IV software. Statistical analyses, including one-way analysis of variance, Chi-square tests, and t-tests, were used to assess the association between dietary intake and food insecurity. More than half (52.9%) of the participants were food insecure, with 35.8% experiencing hunger and 17.1% without hunger. Vitamin B3, C, selenium, and iron had the highest sensitivity, specificity, and accuracy and were the best indicators of food insecurity with and without hunger. The most prevalent nutrient deficiencies were vitamin B9 and E, calcium, magnesium, and zinc inadequacies. Food security was positively associated with fruit, vitamins E and K, dairy products (e.g., milk, yogurt, and cheese), meat products (e.g., chicken, meat, red meat, and egg), and nut intake. Our findings suggest that adolescent girls in Kabul may benefit from food programs that enrich nutrients such as B9 and E, calcium, magnesium, and zinc, which were found to be the most prevalent nutrient deficiencies. These findings highlight the importance of addressing food insecurity and nutrient deficiencies among adolescent girls in Afghanistan.

RESUMO

The year 2024 marks the centennial of the initiation of the American Heart Association. Over the past 100 years, the American Heart Association has led groundbreaking discoveries in cardiovascular disease including salt sensitivity of blood pressure, which has been studied since the mid-1900s. Salt sensitivity of blood pressure is an important risk factor for cardiovascular events, but the phenotype remains unclear because of insufficient understanding of the underlying mechanisms and lack of feasible diagnostic tools. In honor of this centennial, we commemorate the initial discovery of salt sensitivity of blood pressure and chronicle the subsequent scientific discoveries and efforts to mitigate salt-induced cardiovascular disease with American Heart Association leading the way. We also highlight determinants of the pathophysiology of salt sensitivity of blood pressure in humans and recent developments in diagnostic methods and future prospects.

RESUMO

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.

RESUMO

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.

RESUMO

Excess sodium intake is a risk factor for non-communicable diseases (NCDs), such as cardiovascular diseases and hypertension. Therefore, many countries have set nutrient reference values for sodium, specifically for the prevention of NCDs, and intake is routinely monitored by nutrition surveys. In this review, we aimed to compare the global nutrient reference values and national intakes of sodium, along with the methods of intake assessment used. Data were obtained for Australia, Canada, Ireland, Japan, the UK, the US, and the European Food Safety Authority (EFSA), where information was accessible online in English or Japanese. We collected the following information regarding sodium intake: the term used for reference values to prevent NCDs; year when reference values were established or revised; reference values to prevent NCDs; target NCDs; designation of nutrition survey; method for estimating intake; and average intake. The reference values ranged from 2,000 mg (Australia and EFSA) to 2,953 mg (Japan). Sodium intake ranged from 2,431 mg (Australia) to 3,958 mg (Japan). Out of seven countries/institutions, five used dietary assessment, and two used sodium urinary excretion for estimating dietary sodium intake. Among the dietary assessment methods, the 24-h dietary recall was most frequently used. National sodium intake exceeded the reference values in all countries, and reduction of sodium intake remains a global challenge.

RESUMO

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.

RESUMO

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.

RESUMO

Vitamin A deficiency is a major health risk for infants and children in low- and middle-income countries. This scoping review identified, quantified, and mapped research for use in updating nutrient requirements and upper limits for vitamin A in children aged 0 to 48 months, using health-based or modelling-based approaches. Structured searches were run on Medline, EMBASE, and Cochrane Central, from inception to 19 March 2021. Titles and abstracts were assessed independently in duplicate, as were 20% of full texts. Included studies were tabulated by question, methodology and date, with the most relevant data extracted and assessed for risk of bias. We found that the most recent health-based systematic reviews and trials assessed the effects of supplementation, though some addressed the effects of staple food fortification, complementary foods, biofortified maize or cassava, and fortified drinks, on health outcomes. Recent isotopic tracer studies and modelling approaches may help quantify the effects of bio-fortification, fortification, and food-based approaches for increasing vitamin A depots. A systematic review and several trials identified adverse events associated with higher vitamin A intakes, which should be useful for setting upper limits. We have generated and provide a database of relevant research. Full systematic reviews, based on this scoping review, are needed to answer specific questions to set vitamin A requirements and upper limits.

RESUMO

ABSTRACT Objective To develop a scientific consensus on nutrition in cystic fibrosis. Methods Sixteen coordinators elaborated relevant questions on nutritional therapy in cystic fibrosis, which were divided into six sections: nutritional assessment, nutritional recommendations, nutritional intervention, dietary counseling, special situations and enzyme replacement, and gastrointestinal manifestations. Two to three specialists in the field were responsible for each section and obtaining answers formulated based on standardized bibliographic searches. The available literature was searched in the PubMed®/MEDLINE database, after training and standardization of search strategies, to write the best level of evidence for the questions elaborated. Issues related to disagreement were discussed until a consensus was reached among specialists, based on the current scientific literature. Results Forty-two questions were prepared and objectively answered, resulting in a consensus of nutritional therapy in cystic fibrosis. Conclusion This work enabled establishing a scientific consensus for nutritional treatment of cystic fibrosis patients.

RESUMO

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

RESUMO

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.

RESUMO

OBJECTIVES: To identify food sources of nutrients in First Nations adults in Canada and to establish whether these populations are meeting their nutrient requirements and whether traditional foods (TF) contribute to better nutrient intake. METHODS: The First Nations Food, Nutrition and Environment Study is a cross-Canada participatory study of First Nations adults living south of the 60th parallel. Twenty-four-hour recalls were conducted in 92 First Nations communities from 2008 to 2016. Repeat recalls were attempted with 20% of participants to adjust for within-person variation and estimate the proportion of individuals below recommendations according to Institute of Medicine guidelines. Nutrients from days with and without TF were compared. The main food sources of select nutrients were identified, including TF. RESULTS: Mean energy intakes among women and men ranged from 1664 to 1864 and from 1761 to 2298 kcal/day respectively. Most macronutrients were within the acceptable macronutrient diet range except for fat in most age groups and carbohydrates in men 71 years of age and older. Saturated fat was above recommendations for all ages. Only niacin was identified as above recommendations in all age and sex categories. Days where TF were eaten showed greater intakes of key nutrients. CONCLUSION: It is imperative that we find culturally appropriate ways to improve the quality and nutritional value of First Nations Peoples food intake by improving TF access and use on the one hand and conversely providing better quality store-bought foods. For success in this, we must empower First Nations communities and health practitioners to collaboratively overcome these challenges.


RéSUMé: OBJECTIFS: Établir si l'alimentation des adultes des Premières Nations au Canada est satisfaisante et si les aliments traditionnels (AT) contribuent à un meilleur apport en nutriments et identifier les sources alimentaires des nutriments. MéTHODE: L'étude sur l'alimentation, la nutrition et l'environnement chez les Premières Nations est une étude participative pancanadienne visant les adultes des Premières Nations vivant au sud du 60e parallèle. Des rappels de 24 heures ont été effectués dans 92 communautés des Premières Nations de 2008 à 2016. Les rappels ont été répétés avec 20 % des participants pour ajuster la variation intra-individuelle et estimer la proportion d'individus à risque de consommation insuffisante de nutriments selon les apports nutritionnels de référence de l'« Institute of Medicine ¼. Les sources alimentaires (incluant les AT) de certains nutriments ont été identifiées. RéSULTATS: La moyenne des apports énergétiques moyens chez les femmes et les hommes variaient de 1 664 à 1 864 et 1 761 à 2 298 kilocalories/jour respectivement. La plupart des macronutriments se situaient dans l'intervalle établi par l'étendue des valeurs acceptables des macronutriments, à l'exception des lipides dans la plupart des groupes d'âge et des glucides chez les hommes de 71 ans et plus. Les acides gras saturés étaient supérieurs aux recommandations pour tous les âges. Seule la niacine était supérieure au besoin moyen estimatif. Les jours où les AT sont consommés, une augmentation notable dans les apports en certains nutriments-clés est observée. CONCLUSION: Il est important de trouver des moyens pour améliorer la qualité et la valeur nutritionnelle de l'apport alimentaire des Peuples des Premières Nations en respectant leur culture et en offrant un meilleur accès et une utilisation améliorée des AT d'une part et en fournissant des aliments provenant du magasin de meilleure qualité d'autre part. Pour réussir, les communautés des Premières Nations et les professionnels de la santé devraient être impliqués de manière collaborative.

RESUMO

Calcium and vitamin D are inseparable nutrients required for bone health. In the past half a century, the dietary calcium intake of rural, tribal, and urban India has declined. Though India is the largest producer of milk and cereals, the major source of calcium in India is through non-dairy products. The highest intake of cereals and lowest intake of milk & milk products was observed in rural and tribal subjects whereas, the intake of cereals, milk & milk products were similar in both urban and metropolitan subjects. One of the reasons for lower calcium intake was the proportion of calcium derived from dairy sources. Over the past half a century, the average 30-day consumption of cereals in the rural and urban population has declined by 30%. The Per Capita Cereal Consumption (PCCC)has declined despite sustained raise in Monthly Per capita Consumption Expenditure (MPCE) in both rural and urban households. The cereal consumption was the highest in the lowest income group, despite spending smaller portion of their income, as cereals were supplied through public distribution system (PDS). About 85% of the Indian population are vitamin D deficient despite abundant sunlight. Dietary calcium deficiency can cause secondary vitamin D deficiency. Though India as a nation is the largest producer of milk, there is profound shortage of calcium intake in the diet with all negative consequences on bone health. There is a decline in dietary calcium in the background of upward revision of RDI/RDA. There is a gap in the production-consumption-supply chain with respect to dietary calcium. To achieve a strong bone health across India, it is imperative to have population based strategies addressing different segments including supplementing dietary/supplemental calcium in ICDS, mid-day-meals scheme, public distribution system, educational strategies. Other measures like mass food fortification, biofortification, bioaddition, leveraging digital technologies, investments from corporate sector are some measures which can address this problem. India is a vast country with diverse social, cultural and dietary habits. No single measure can address this problem and requires a multi-pronged strategic approach to tackle the dietary calcium deficiency to achieve strong bone health while solving the problem of nutritional deficiency.

RESUMO

BACKGROUND: The overarching objective was to examine the effectiveness of intervention strategies to promote fruit and vegetable consumption. To do this, systematic review evidence regarding the effects of intervention strategies was synthesized; organized, where appropriate, by the setting in which the strategies were implemented. Additionally, we sought to describe gaps in the review of evidence; that is, where evidence regarding the effectiveness of recommended policy actions had not been systematically synthesised. METHODS: We undertook a systematic search of electronic databases and the grey literature to identify systematic reviews describing the effects of any intervention strategy targeting fruit and/or vegetable intake in children or adults of any age. RESULTS: The effects of 32 intervention strategies were synthesised from the 19 included reviews. The strategies were mapped across all three broad domains of the NOURISHING framework (i.e. food environment, food system and behaviour change communication), but covered just 14 of the framework's 65 sub-policy areas. There was evidence supporting the effectiveness of 19 of the 32 intervention strategies. The findings of the umbrella review suggest that intervention strategies implemented within schools, childcare services, homes, workplaces and primary care can be effective, as can eHealth strategies, mass media campaigns, household food production strategies and fiscal interventions. CONCLUSIONS: A range of effective strategy options are available for policy makers and practitioners interested in improving fruit and/or vegetable intake. However, the effects of many strategies - particularly those targeting agricultural production practices, the supply chain and the broader food system - have not been reported in systematic reviews. Primary studies assessing the effects of these strategies, and the inclusion of such studies in systematic reviews, are needed to better inform national and international efforts to improve public health nutrition. TRIAL REGISTRATION: The review protocol was deposited in a publicly available Open Science framework prior to execution of the search strategy. https://osf.io/unj7x/.

RESUMO

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 de1998. 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.

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.

RESUMO

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.


La Guía Alimentaria para la Población Brasileña está reconocida como un potente inductor de políticas públicas de alimentación y nutrición. 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.

RESUMO

Understanding the potential uptake and biodistribution of engineered nanoparticles (ENPs) in soil-grown plants is imperative for realistic toxicity and risk assessment considering the oral intake of edibles by humans. Herein, growing N-fixing symbiont (Bradyrhizobium japonicum) inoculated soybean (Glycine max (L.) Merr.) for a full lifecycle of 120 days, we assessed the potential influence of particle size (25, 50, and 250 nm) and concentration (0, 50, 100, 200, and 500 mg/kg soil) of Copper oxide nanoparticles (CuONPs) on: (1) root system architecture, (2) soil physicochemical attributes at the soil-root interface, and (3) Cu transport and accumulation in root, stem, leaf, and seed in soybean, and compared them with the soluble Cu2+ ions and water-only controls. Finally, we performed a comparative assessment of total seed Cu levels in soybean with other valuable food sources for Cu intake and discussed potential human health implications. Results showed particle size- and concentration-dependent influence of CuONPs on Cu uptake and distribution in root, stem, leaf, and seed. Alterations in root architecture (root biomass, length, volume, and area) were dependent on the Cu compound types, Cu concentrations, and their interactions. Concentration-response relationships for all three sizes of CuONPs and Cu2+ ions were found to be linear. Furthermore, CuONPs and Cu2+ ions had inhibitory effects on root growth and development. Overall, soybean responses to the smallest size of CuONPs-25 nm-were greater for all parameters tested compared to the two larger-sized CuONPs (50 nm, 250 nm) or Cu2+ ions. Results suggest that minor changes in soil-root physicochemical attributes may not be a major driver for Cu uptake in soybean. Cu bioaccumulation followed the order: root > leaf > stem > seed. Despite reduction in root architecture and seed yield, the smallest size CuONPs-25 nm led to increased total seed Cu uptake compared to the larger-sized CuONPs or Cu2+ ions. Our findings also suggest that soil amendment with CuONPs, and more so with the smallest size of CuONPs-25 nm-could significantly improve seed nutritional Cu value in soybean as reflected by the % Daily Values (DV) and are rated "Good" to "Very Good" according to the "World's Healthiest Foods" rating. However, until the potential toxicity and risk from CuONP-fortified soybean seed ingestion is characterized in humans, we caution recommending such seeds for daily human consumption when addressing food Cu-deficiency and associated diseases, globally.

RESUMO

BACKGROUND: Consumption of sugars contributes to obesity and various chronic diseases. The U.S. Department of Agriculture and the World Health Organization recommend that added and free sugar consumption be less than 10% of total energy intake (TEI). However, in Canada, the added and free sugar content of foods and beverages is not documented, so Canadians' consumption and compliance with the above recommendations are unknown. DATA AND METHODS: This study calculated the added and free sugar content of all 5,374 foods and beverages recorded in the 24-hour dietary recalls of the 2015 Canadian Community Health Survey - Nutrition using established procedures. The usual intake of added, free and total sugars was estimated with the National Cancer Institute method. RESULTS: In 2015, residents of Canada consumed an average of 57.1 g/day of added sugars, 67.1 g/day of free sugars and 105.6 g/day of total sugars. This represented 11.1%, 13.3% and 21.6% of TEI for added, free and total sugar intake, respectively. Among all Canadians, 49.0% consumed less than 10% of TEI from added sugars, while 33.8% consumed less than 10% of TEI from free sugars. The food groups with the highest added and free sugar content were desserts and sweets, breakfast cereals, baked products, beverages, and snacks. Desserts and sweets and beverages were the two main contributors of sugar in the Canadian diet. DISCUSSION: The majority of Canadians consumed more added and free sugars than recommended. Estimating added and free sugar content and consumption could help researchers assess the health of Canadians and the economic burden of excessive sugar consumption and could help policy makers articulate intervention targets.

RESUMO

BACKGROUND: HIV/AIDS is a hallmark of immune suppression. Micronutrient deficiencies in diet and recurrent opportunistic infections play major roles in the lives of people living with HIV. Although benefits of providing adequate diet to HIV positive persons are well documented, the demand for key elements still remain unclear in particular settings, especially in low and middle-income countries. METHODS: This was a cross sectional analysis of baseline data collected from HIV-infected adults initiating antiretroviral therapy, and who were enrolled in a multivitamin supplementation trial. A food frequency questionnaire was used and intake were obtained as a product of quantities consumed. Adequacy was calculated as the proportion of Recommended Dietary Allowances (RDA). A chi square test and logistic regression analysis were used at p-value 0.05 to show significant associations. RESULTS: Mean intakes were above minimum requirements for analyzed micronutrients with the exception of Calcium and Iron. Participants who met RDA intakes were as follows: highest (≥ 80%) for Magnesium, Selenium, Zinc and Vitamins B2, B6, B9, C and E; moderate (50% to <80%) for Vitamins B3, and A; and lowest (≤50%) for Iron (30%), Calcium (14.9%), Vitamins B12 and B1. Gender differences in met RDA were observed for Iron, Selenium, Zinc, Vitamins A, B1, B3 and E. In multivariable analyses, nutritional status and CD4 count had no influence on meeting RDA for majority of micronutrients such as magnesium, Selenium, B class vitamins (B1, B2, B3, B6, B9, B12), vitamin (A, C, and E), Zinc and Calcium, but not including iron. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: Diets consumed by the study participants were low in most protective nutrients (Iron, Calcium, Zinc, Vitamin A, B1, B3, and B12). This deficiency was more common among females than males, and irrespective of BMI or CD 4 count. Findings warrant further investigation on the impact and cost implications for suplementation interventions that target the elements lacking in the diets of people living with HIV in similar low-resourced settings.

RESUMO

The quality and nutritional value of dietary proteins are determined by the quantity, digestibility and bioavailability of essential amino acids (EAA), which play a critical role in human growth, longevity and metabolic health. Plant-source protein is often deficient in one or more EAAs (e.g., branched-chain amino acids, lysine, methionine and/or tryptophan) and, in its natural form, is less digestible than animal-source protein. Nevertheless, dietary intake of plant-source protein has been promoted because of its potential health benefits, lower cost of production and lower environmental impact compared to animal-source protein. Implementation of dietary strategies that improve both human and planetary health are of critical importance and subject to growing interest from researchers and consumers. Therefore, in this review we analyse current plant protein intake patterns and discuss possible countermeasures that can enhance plant protein nutrition, examples include: (1) combining different plant proteins with complementary EAA profiles; (2) identification and commercial cultivation of new and novel high-quality plant proteins; (3) industrial and domestic processing methods; and (4) genome-editing techniques.
