Cadmium toxicity symptoms and uptake mechanism in plants: a review / Sintomas de toxicidade de cádmio e mecanismo de absorção em plantas: uma revisão

Cadmium (Cd) is one of non-essential heavy metals which is released into environment naturally or anthropogenically. It is highly persistent toxic metals that are exceptionally distressing industrial and agriculture activities by contaminating soil, water and food. Its long-duration endurance in soil and water results in accumulation and uptake into plants, leading to the food chain. This becomes a serious global problem threatening humans and animals as food chain components. Living organisms, especially humans, are exposed to Cd through plants as one of the main vegetative food sources. This review paper is concentrated on the symptoms of the plants affected by Cd toxicity. The absorption of Cd triggers several seen and unseen symptoms by polluted plants such as stunted growth, chlorosis, necrosis and wilting. Apart from that, factors that affect the uptake and translocation of Cd in plants are elaborated to understand the mechanism that contributes to its accumulation. By insight of Cd accumulation, this review also discussed the phytoremediation techniques-phytoextraction, phytostimulation, phytostabilization, phytovolatization and rhizofiltration in bioremediating the Cd.

O cádmio (Cd) é um dos metais pesados ​​não essenciais que é liberado no meio ambiente de forma natural ou antropogênica. São metais tóxicos altamente persistentes que prejudicam excepcionalmente as atividades industriais e agrícolas, contaminando o solo, a água e os alimentos. Sua resistência de longa duração no solo e na água resulta em acúmulo e absorção pelas plantas, levando à cadeia alimentar. Isso se torna um sério problema global que ameaça humanos e animais como componentes da cadeia alimentar. Os organismos vivos, principalmente os humanos, são expostos ao Cd através das plantas como uma das principais fontes de alimento vegetativo. Este artigo de revisão concentra-se nos sintomas das plantas afetadas pela toxicidade do Cd. A absorção de Cd desencadeia vários sintomas visíveis e invisíveis por plantas poluídas, como crescimento atrofiado, clorose, necrose e murcha. Além disso, são elaborados fatores que afetam a absorção e translocação de Cd nas plantas para entender o mecanismo que contribui para o seu acúmulo. A partir do conhecimento do acúmulo de Cd, esta revisão também discutiu as técnicas de fitorremediação - fitoextração, fitoestimulação, fitoestabilização, fitovolatização e rizofiltração na biorremediação do Cd.

Trajetória das políticas de educação alimentar e nutricional no Brasil / Trajectory of food and nutritional education policies in Brazil / Trayectoria de las políticas de educación alimentaria y nutricional en Brasil

RESUMO: A Educação Alimentar e Nutricional é o campo de conhecimento que leva em conta as representações sobre o comer e a comida, os conhecimentos e os valores da alimentação, com vistas à autonomia de escolha dos sujeitos em questões relacionadas à alimentação e à nutrição. Este texto é resultado de uma pesquisa teórica com o objetivo de identificar a trajetória da Educação Alimentar e Nutricional no Brasil, que a delineou como campo de conhecimento. As políticas atuais desse campo de conhecimento são fruto da superação de um passado em que predominavam abordagens educativas voltadas para a alimentação que ocorriam de forma descontextualizada, normativa e estritamente biológica. Essa trajetória envolve disputas em sua teoria e prática que evidenciam que a resolução do problema da alimentação no Brasil é perpassada por uma profunda reestruturação econômica e social. Destacamos a necessidade de que as práticas de Educação Alimentar e Nutricional sejam pautadas pela perspectiva crítica e emancipatória de educação.

ABSTRACT: Food and Nutrition Education is the field of knowledge that takes into account the representations about eating and food, knowledge and values of food, with a view to the autonomy of choice of subjects in matters related to food and nutrition. This text is the result of a theoretical research aimed at identifying the trajectory of Food and Nutritional Education in Brazil, which outlined it as a field of knowledge. The current policies of this field of knowledge are the result of overcoming a past where educational approaches focused on food predominated that took place in a decontextualized, normative and strictly biological way. This trajectory involves disputes in its theory and practice that show that the resolution of the food problem in Brazil is permeated by a profound economic and social restructuring. We highlight the need for the practices of Food and Nutrition Education to be guided by the critical and emancipatory perspective of education.

Este texto es el resultado de una investigación teórica dirigida a identificar la trayectoria de la Educación Alimentaria y Nutricional en Brasil, la cual la delineó como un campo de conocimiento. Las políticas actuales de este campo del conocimiento son el resultado de superar un pasado donde predominaron los enfoques educativos centrados en la alimentación que se desarrollaron de manera descontextualizada, normativa y estrictamente biológica. Esta trayectoria implica disputas en su teoría y práctica que muestran que la resolución del problema alimentario en Brasil está impregnada por una profunda reestructuración económica y social. Destacamos la necesidad de que las prácticas de Educación Alimentaria y Nutricional se guíen por la perspectiva crítica y emancipadora de la educación.

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

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

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

Aplicación del perfil de nutrientes de la OPS en productos ultraprocesados, inclusive en alimentos fortificados / Application of PAHO's nutrient profile in ultra-processed products, including fortified foods

Resumen Introducción: en la actualidad se recomienda limitar el consumo de productos ultraprocesados por su alto contenido en azúcar, grasas totales, grasas saturadas, grasas trans y sodio. El etiquetado frontal es una estrategia destinada a fortalecer en el consumidor su capacidad de elegir, pero la estrategia de adición de micronutrientes realizada por la industria alimentaria contribuye a que los consumidores sobrestimen su calidad nutricional. El objetivo de este estudio fue analizar según el modelo del Perfil de Nutrientes (PN) de la Organización Panamericana de la Salud (OPS), un grupo de productos ultraprocesados disponibles en el mercado argentino y aplicar el modelo de forma diferenciada en productos fortificados por la industria alimentaria. Materiales y método: estudio de campo, transversal, descriptivo. Se aplicó el perfil de nutrientes considerando: azúcares libres, grasas totales, grasas saturadas, grasas trans y sodio, en productos fortificados y sin fortificación. Cada una de las categorías generales de alimentos: galletitas dulces, alfajores, chocolates, golosinas, helados, cereales, bebidas, dulces untables, snacks salados y lácteos, fueron divididas en subcategorías, integradas por diferentes productos. Se realizó un análisis estadístico descriptivo por subcategorías. Resultados: la muestra se conformó por 682 productos y todos superaron el punto de corte de al menos un nutriente en cantidad excesiva. El 100% de los productos fortificados (n=146) presentó cantidad excesiva de algún nutriente, el 41,1% tuvo un nutriente en cantidad excesiva y el 50,7% dos nutrientes. 95,7-100% de los productos de los grupos cereales de desayuno, chocolatadas, yogures bebibles y en pote, se categorizaron como con cantidad excesiva de azúcares libres. Conclusiones: todos los productos analizados presentaron al menos un nutriente del PN de referencia, en cantidad excesiva. Los mismos productos tenían adición de vitaminas, minerales o fibra. Se visibiliza la necesidad de realizar estudios que investiguen si esta estrategia induce confusión en el consumidor al momento de elegir.

Abstract Introduction: it is currently recommended to limit the consumption of ultra-processed products because of their high content of sugar, total fats, saturated fats, trans fats and sodium. Front labelling is a strategy aimed at strengthening consumer choice, but the micronutrient addition strategy carried out by the food industry contributes to consumers overestimating their nutritional quality. The objective of this study was to analyze, following the model of the Nutrient Profile (PN) of the Pan American Health Organization (PAHO), a group of ultra-processed products available in the Argentine market and apply the model in a differentiated way in products fortified by the food industry. Materials and method: field study, cross-sectional, descriptive. The nutrient profile was applied considering: free sugars, total fats, saturated fats, trans fats and sodium, both in fortified and unfortified products. Each of the general food categories: sweet cookies, alfajores, chocolates, sweets, ice cream, cereals, beverages, spreadable sweets, salty snacks and dairy products, were divided into subcategories, made up of different products. A descriptive statistical analysis by subcategories was performed. Results: the sample consisted of 682 products and all exceeded the cut-off point of at least one nutrient in excessive quantity. 100% of the fortified products (n=146) had an excessive amount of some nutrient, 41.1% had an excess nutrient and 50.7% two nutrients. 95.7-100% of the products of the breakfast cereals, chocolate, drinking and potted yogurts groups were categorized as having excessive amounts of free sugars. Conclusions: all the products analyzed presented at least one nutrient from the reference NP, in excessive quantity. The same products had added vitamins, minerals or fiber. The need for studies to research whether this strategy induces confusion in the consumer when choosing is made visible.

Proteínas oxidadas de origen animal y su impacto sobre la salud intestinal / Oxidized proteins of animal origin and their impact on intestinal health / Proteínas oxidadas de origem animal e seu impacto na saúde intestinal

Los alimentos de origen animal como la carne de pollo, res, pescado y cerdo poseen una amplia demanda en todo el mundo debido, entre otros aspectos, a su valor nutricional, asociado al alto contenido proteico. No obstante, este tipo de proteínas son susceptibles de sufrir reacciones de oxidación, las cuales pueden mediar procesos de fragmentación, agregación, pérdida de solubilidad, funcionalidad y digestibilidad proteica; eventos implicados en la pérdida de su valor nutricional. En este sentido, las proteínas agrega­das tienden a no ser digeridas en el tracto gastrointestinal y acumularse en el intestino (colon), donde la microbiota colónica las degrada a productos mutagénicos como fenol y p-cresol, lo que incrementa el riesgo de cáncer colorrectal. Por otra parte, los ami­noácidos o péptidos oxidados liberados en la digestión podrían incorporarse en las vías de señalización celular intestinal y favorecer o exacerbar procesos intestinales crónicos como colon irritable o enfermedad de Crohn. Debido al gran interés de esta temática en los últimos años, el objetivo de esta revisión es realizar una descripción general del impacto de proteínas oxidadas de origen animal sobre la salud intestinal.

Animal foods such as chicken, beef, fish and pork are in wide demand throughout the world due, among other things, to their nutritional value, associated with their high protein content. However, this type of protein is susceptible to oxidation reactions, which can mediate processes of fragmentation, aggregation, loss of solubility, functionality, and protein digestibility, which are events involved in the loss of their nutritional value. In this sense, aggregated proteins tend not to be digested in the gastrointestinal tract and accumulate in the intestine (colon), where the colonic microbiota degrades them into mutagenic products such as phenol and p-cresol, which increases the risk of colorectal cancer. On the other hand, the oxidized amino acids or peptides released in digestion could be incorporated into intestinal cell signaling pathways and favor or exacerbate chronic intestinal processes such as irritable bowel syndrome or Crohn's disease. Due to the great interest in this topic in recent years, the objective of this review is to provide a general overview of the impact of oxidized proteins of animal origin on intestinal health.

Alimentos de origem animal como frango, carne bovina, peixe e carne suína são muito procurados em todo o mundo devido, entre outros fatores, ao seu valor nutricional, associado ao seu alto teor de proteínas. No entanto, esse tipo de proteína é suscetível a reações de oxidação, que podem mediar processos de fragmentação, agregação, perda de solubilidade, funcionalidade e digestibilidade da proteína; eventos envolvidos na perda de seu valor nutritivo. Nesse sentido, as proteínas agregadas tendem a não ser digeridas no trato gastrointestinal e se acumulam no intestino (cólon), onde a microbiota colônica as degrada em produtos mutagênicos como fenol e p - cresol, aumentando o risco de câncer colorretal. Por outro lado, os aminoácidos ou peptídeos oxidados liberados na digestão poderiam ser incorporados às vias de sinalização das células intestinais e favorecer ou exacerbar processos intestinais crônicos, como a síndrome do intestino irritável ou a doença de Crohn. Devido ao grande interesse neste tema nos últimos anos, o objetivo desta revisão é fornecer uma descrição geral do impacto das proteínas oxidadas de origem animal na saúde intestinal.

Intake of allergenic foods at 1.5 years and 3 years of age in a general child population in Japan: a cross-sectional study

BACKGROUND@#Recent studies indicate that the timing of introduction of potentially allergenic food is crucial for the development of food allergy in children. This cross-sectional study aimed to clarify the reality of allergen food intake in a general population of young children in Japan.@*METHODS@#A questionnaire survey of caregivers was conducted at health checkups for 1.5-year (18-month)-old and 3-year-old children in the fall of 2020. The caregivers were asked about (1) the presence/absence of allergic disease symptoms based on the ISAAC questionnaire, and (2) foods that caregivers avoided giving their children. Ordinal logistic regression analyses were periformed to determine factors associated with food avoidance.@*RESULTS@#Questionnaires were distributed to 1720 caregivers, and 1603 (93%) responded. The responders consisted of 771 and 832 caregivers who participated in 1.5-year-old and 3-year-old checkups, respectively. The prevalence of allergic diseases was comparable to recent epidemiological studies in Japan, indicating that the population may be representative. At 1.5 years old, more than 50% of the children were not exposed to peanuts, tree nuts, fish eggs, shellfish, and buckwheat. At 3 years old, the avoidance rates of the foods had decreased but were still between 18.8% and 32.0%. On the other hand, the avoidance rates of chicken egg and cow's milk, the top 2 common allergenic foods in Japan, were much lower at 2.8% and 1.5% at 1.5 years, and they decreased to 1.4% and 0.7% at 3 years old, respectively. Ordinal logistic analysis showed that avoidance of chicken egg, cow's milk, and wheat was associated with food allergy diagnosis and chicken egg avoidance with eczema, but avoidance of other foods showed no associations with any risk factors for food allergy.@*CONCLUSION@#Caregivers avoided giving various foods, independent of allergy risk factors, to their young children. Since delayed introduction of an allergenic food has been reported to increase the risk of developing an allergy to the food, the results warrant future investigation of the development of food allergies in relation to current eating habits and recommendations.

Mechanism of Xiaoer Chiqiao Qingre Granules in clearing heat and removing food stagnation in suckling rats with fever and food accumulation based on metabolomics / 中国中药杂志

Children's fever is often accompanied by food accumulation. Traditional Chinese medicine believes that removing food stagnation while clearing heat of children can effectively avoid heat damage. To systematically evaluate the efficacy of Xiaoer Chiqiao Qingre Granules(XRCQ) in clearing heat and removing food accumulation and explore its potential mechanism, this study combined suckling SD rats fed with high-sugar and high-fat diet with injection of carrageenan to induce rat model of fever and food accumulation. This study provided references for the study on the pharmacodynamics and mechanism of XRCQ. The results showed that XRCQ effectively reduced the rectal temperature of suckling rats, improved the inflammatory environment such as the content of interleukin-1β(IL-1β), interleukin-2(IL-2), interferon-γ(IFN-γ), white blood cells, and monocytes. XRCQ also effectively repaired intestinal injury and enhanced intestinal propulsion function. According to the confirmation of its efficacy of clearing heat, the thermolytic mechanism of XRCQ was further explored by non-targeted and targeted metabolomics methods based on LTQ-Orbitrap MS/MS and UPLC-QQQ-MS/MS. Non-target metabolomics analysis of brain tissue samples was performed by QI software combined with SIMCA-P software, and 22 endogenous metabolites that could be significantly regulated were screened out. MetaboAnalyst pathway enrichment results showed that the intervention mechanism was mainly focused on tyrosine metabolism, tricarboxylic acid cycle, inositol phosphate metabolism, and other pathways. At the same time, the results of targeted metabolomics of brain tissue samples showed that XRCQ changed the vitality of digestive system, and inhibited abnormal energy metabolism and inflammatory response, playing a role in clearing heat and removing food stagnation from multiple levels.

Quantification of Polycyclic Aromatic Hydrocarbons in Commonly Consumed Salami in Brazil

Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that have been found in different food categories, and meat products can have high concentrations of PAHs, since the technological processes to which they are subjected, such as smoking, can produce several compounds. Considering the risk that these compounds can bring to the population's health, it is essential to develop an accurate and reliable method to evaluate the contamination of PAHs in products of animal origin. The objective of this study was to optimize and validate a method for the quantification of 4 PAHs (benz[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene) in salami. The methodology included saponification, liquid­liquid extraction, solid-phase purification, and quantification by ultra-high-performance liquid chromatography. The effects of saponification parameters were investigated by experimental design, whereas the model obtained by regression analysis was considered satisfactory with the dissolution solvent of potassium hydroxide providing the highest global sum of areas. In validation, the parameters studied were adequate and within European and INMETRO Guidelines limits. The evaluation of 22 samples indicated that 27% were contaminated with at least one of the 4 PAHs, and benz[a]anthracene being the prevalent one with content varying between < 1.00 and 17.58 µg/kg. Two samples showed PAHs contamination above the maximum tolerable limit in the European Commission Regulation.

Pandemia da Covid-19 Efeitos no ambiente alimentar de varejo em três municípios da região metropolitana de Belo Horizonte / Covid-19 pandemic: Effects on the retail food environment in three municipalities in the metropolitan region of Belo Horizonte

Objetivo: Identificar mudanças no ambiente alimentar de varejo decorrentes da pandemia de covid-19, no ano de 2020, bem como analisar o fechamento dos estabelecimentos de venda de alimentos diante das medidas restritivas implementadas na região metropolitana de Belo Horizonte- MG. Metodologia: Estudo ecológico realizado em três cidades da região metropolitana de Belo Horizonte. Foram utilizados dados secundários da Secretaria Estadual da Fazenda, do Instituto Brasileiro de Geografia e Estatística, da Secretaria Estadual de Saúde do Estado de Minas Gerais e das e Secretarias Municipais de Saúde. Avaliaram-se as seguintes variáveis: abertura e fechamento de estabelecimentos que comercializavam alimentos segundo o tipo e categorias de estabelecimentos, sendo comparadas as medidas restritivas implementadas em cada cidade com o fechamento desses estabelecimentos. Os estabelecimentos foram classificados de acordo com o código da Classificação Nacional das Atividades Econômicas (CNAE), a partir da CNAE, os estabelecimentos de alimentos foram classificados conforme a atividade fim realizada e predominância dos alimentos comercializados, sendo agrupados seguindo os critérios apresentados no Relatório Técnico de Mapeamento de Desertos Alimentares para o Brasil elaborado pela Câmara Interministerial de Segurança Alimentar e Nutricional (CAISAN), sendo categorizados em três categorias, (1) estabelecimentos de aquisição de in natura, (2) estabelecimentos mistos, (3) estabelecimentos de aquisição de ultraprocessados. Por fim, estes estabelecimentos foram agregados segundo o perfil de aquisição e consumo de alimentos sendo agrupados em duas categorias (1) estabelecimentos para consumo imediato, (2) estabelecimentos para consumo no domicílio. Ademais, por se tratar de um estudo que avaliou o ambiente alimentar durante a pandemia de Covid-19, foram incluídas no estudo variáveis que descreviam o comportamento da pandemia nas cidades, tais como, a incidência da doença, taxa de mortalidade e medidas legislativas que foram utilizadas durante o primeiro ano da pandemia. Por fim, os estabelecimentos que fecharam em 2020 foram descritos de acordo com a vulnerabilidade do setor censitário onde estavam localizados os estabelecimentos. A vulnerabilidade foi determinada pela renda per capita do setor (renda total/ população total), foram utilizados dados do Censo Demográfico de 2010. Foi realizada análise descritiva (frequência relativa) com o auxílio do software Stata 14.0 e mapas com o uso do software QGIS 2.10.1. Resultados: Dentre os estabelecimentos que fecharam durante o primeiro ano de pandemia, a maioria comercializava alimentos para consumo imediato (Belo Horizonte 76,53%; Betim 69,95% e Contagem 70,87%). Além disso, foi possível perceber um aumento na abertura de estabelecimentos do tipo delivery nas três cidades do estudo. Apesar disso, as características gerais do ambiente alimentar de varejo se mantiveram inalteradas nas três cidades, com alta disponibilidade dos estabelecimentos que comercializavam predominantemente alimentos ultraprocessados. Conclusão: A pandemia de Covid-19 parece ter impactado mais os estabelecimentos que comercializam alimentos para consumo imediato. Contudo, ainda não é possível afirmar a dimensão do impacto gerado pela pandemia, para isso é necessário um acompanhamento a longo prazo para identificar se ocorre remodelação do ambiente alimentar

Objective: To identify changes in the retail food environment resulting from the covid-19 pandemic, in the year 2020, as well as to analyze the closure of food outlets in the face of the restrictive measures implemented in the metropolitan region of Belo Horizonte-MG. Methodology: Ecological study carried out in three cities in the metropolitan region of Belo Horizonte. Secondary data from the State Department of Finance, the Brazilian Institute of Geography and Statistics, the State Department of Health of the State of Minas Gerais and the Municipal Health Departments were used. The following variables were evaluated: opening and closing of establishments that sold food according to the type and categories of establishments, comparing the restrictive measures implemented in each city with the closure of these establishments. The establishments were classified according to the code of the National Classification of Economic Activities (CNAE), based on the CNAE, the food establishments were classified according to the core activity carried out and the predominance of food sold, being grouped according to the criteria presented in the Technical Report Mapping of Food Deserts for Brazil prepared by the Interministerial Chamber of Food and Nutritional Security (CAISAN), being categorized into three categories, (1) establishments for the acquisition of in natura, (2) mixed establishments, (3) establishments for the acquisition of ultra-processed. Finally, these establishments were aggregated according to the profile of acquisition and consumption of food, being grouped into two categories (1) establishments for immediate consumption, (2) establishments for consumption at home. Furthermore, as this is a study that evaluated the food environment during the Covid-19 pandemic, variables that described the behavior of the pandemic in cities were included in the study, such as the incidence of the disease, mortality rate and legislative measures that were used during the first year of the pandemic. Finally, establishments that closed in 2020 were described according to the vulnerability of the census sector where the establishments were located. Vulnerability was determined by the sector's per capita income (total income/total population), data from the 2010 Population Census were used. Descriptive analysis (relative frequency) was performed using Stata 14.0 software and maps using QGIS software 2.10.1. Results: Among the establishments that closed during the first year of the pandemic, most sold food for immediate consumption (Belo Horizonte 76.53%; Betim 69.95% and Contagem 70.87%). In addition, it was possible to notice an increase in the opening of delivery establishments in the three cities of the study. Despite this, the general characteristics of the retail food environment remained unchanged in the three cities, with high availability of establishments that predominantly sold ultra-processed foods. Conclusion: The Covid-19 pandemic seems to have had a greater impact on establishments that sell food for immediate consumption. However, it is still not possible to state the dimension of the impact generated by the pandemic, for which long-term monitoring is necessary to identify whether there is a remodeling of the food environment.

Application of a low copper diet guidance based on food exchange portions in children with hepatolenticular degeneration / 中国当代儿科杂志

OBJECTIVES@#To study the efficacy of a low-copper diet guidance based on food exchange portions in children with hepatolenticular degeneration.@*METHODS@#A self-controlled study was conducted from July 2021 to June 2022, including 30 children under the age of 18 who were diagnosed with hepatolenticular degeneration and poorly controlled with a low-copper diet. During the medical visit, personalized low-copper diet guidance was provided to the children and their parents using a copper-containing food exchange table and a copper food exchange chart. During home care, compliance with the low-copper diet of the children was improved by recording dietary diaries and conducting regular follow-ups. The changes in 24-hour urine copper level, liver function indicators, and the low-copper diet knowledge of the children's parents were observed before and after the intervention, with no change in the original drug treatment.@*RESULTS@#After 8, 16, and 24 weeks of intervention, the 24-hour urine copper level decreased significantly compared to before intervention (P<0.05). When compared to 8-week intervention, the urine copper level decreased significantly after 16 and 24 weeks of intervention. The 24-hour urine copper level after 24 weeks of intervention decreased significantly compared to 16 weeks of intervention (P<0.05).After 24 weeks of intervention, the alanine aminotransferase and aspartate aminotransferase levels decreased significantly compared to before intervention (P<0.05). Additionally, in 16 of the cases (53%), alanine aminotransferase and aspartate aminotransferase returned to normal levels. Following 8 weeks of intervention, the low-copper diet knowledge of the children's parents increased significantly (P<0.05).@*CONCLUSIONS@#A low-copper diet guidance based on food exchange portions can effectively decrease the urine copper level and improve liver function in children with hepatolenticular degeneration. Furthermore, it can increase the low-copper diet knowledge of the children's parents.

Deepening the Action on Salt Reduction in China-suggestions on strategy and implementation plan / 中华预防医学杂志

Excessive sodium/salt intake is the leading dietary risk factor for the loss of healthy life in the Chinese population. The "Healthy China 2030" Action Plan set the goal of reducing salt intake by 20% by 2030. However, salt intake in China is still at a very high level in the world, with adults reaching 11 g/d, more than twice the recommended limit of 5 g/d. The current policies and action plans of China have targeted catering workers, children, adolescents, and home chefs in salt, oil, and sugar reduction actions. However, there are still obvious deficiencies in the coordinated promotion and implementation. This study, therefore, proposed a set of comprehensive strategies (named CHRPS that is composed of communication and education, salt reduction in home cooking, salt reduction in restaurants, reducing salt content in pre-packaged food, and surveillance and evaluation) and key implementation points for further deepening the salt reduction action in China. These strategies were developed based on the main sources of dietary sodium for Chinese residents, the status of "knowledge, attitude and practice" in salt reduction, evidence of effective intervention measures, existing policies and requirements, and the salt reduction strategies of the World Health Organization and experience from some other countries. As a scientific reference, the CHRPS strategies will help the government and relevant organizations quickly implement salt reduction work and facilitate the earlier realization of China's salt reduction goal.
