Food consumption among adolescents and biological and adiposity outcomes / Consumo alimentar entre adolescentes e desfechos biológicos e de adiposidade

Objective: to investigate the association between macronutrient consumption and biological and adiposity indicators in adolescents. Methods: A total of 77 adolescents were evaluated in relation to anthropometric measurements, sexual maturation, body composition, sociodemographic variables, and food composition. Results: the percentage of lipids in relation to total energy intake was positively related to age (ß = 1.33; 95% CI = 0.37 to 2.28), and inversely related to sexual maturation (ß = -2.44; 95% CI =-4.68 to ­ 0.20). Girls had a higher consumption of lipids than boys (ß= 4.59; 95% CI = 0.62 to 8.57). Age was positively associated with the consumption of saturated (ß = 0.62; 95% CI =0,30 to 0,94) and monounsaturated fatty acids (ß=0.48; 95% CI = 0.16 to 0.79). Sexual maturation was inversely associated with the consumption of saturated (ß=-1.7; 95% CI = -2.46 to -0.95), monounsaturated (ß = -1.59; 95% CI = -2.34 to -0.84), and trans fatty acids (ß = -0.32; 95% CI = -0.34 to -0.00). Fat mass showed a positive association with the consumption of saturated (ß = 0.18; 95%CI = 0.03 to 0.32) and monounsaturated fatty acids (ß = 0.23; 95% CI =0.091 to 0.38). Conclusion: The consumption of lipids was positively related to age and inversely related to sexual maturation; fat mass was positively associated with the consumption of saturated and monounsaturated fatty acids. The findings of this study reinforce the concern regarding a high-fat diet among adolescents, especially older girls.

Objetivo: investigar a associação entre consumo de macronutrientes, indicadores biológicos e de adiposidade em adolescentes. Métodos: foram avaliados 77 adolescentes em relação às medidas antropométricas, maturação sexual, composição corporal, sociodemográficas e composição alimentar. Resultados: O percentual de lipídios em relação à ingestão energética total foi positivamente relacionado à idade (ß = 1,33; IC95% 0,37 a 2,28) e inversamente relacionado à maturação sexual (ß = -2,44; IC95% -4,68 a ­0,20). As meninas apresentaram maior consumo desses lipídios quando comparadas aos meninos (ß= 4,59; IC95% 0,62 a 8,57). A idade associou-se positivamente ao consumo de ácidos graxos saturados (ß = 0,62; IC95% 0,30 a 0,94) e monoinsaturados (ß = 0,48; IC95% 0,16 a 0,79). A maturação sexual foi inversamente associada ao consumo de ácidos graxos saturados (ß=-1,7; IC95% -2,46 a -0,95), monoinsaturados (ß = -1,59; IC95% -2,34 a -0,84) e trans (ß = -0,32; IC95% -0,34 a -0,00). A massa gorda apresentou associação positiva com o consumo de ácidos graxos saturados (ß = 0,18; IC95% 0,03 a 0,32) e monoinsaturados (ß = 0,23; IC95% 0,091 a 0,38). Conclusão: O consumo de lipídios esteve positivamente relacionado com a idade e inversamente relacionado com a maturação sexual; a massa gorda foi positiva associada ao consumo de ácidos graxos saturados e monoinsaturados. Os achados desta pesquisa reforçam a preocupação quanto a uma alimentação hiper lipídica entre adolescentes, especialmente entre as meninas com maior idade.

Tolerability of glutamine supplementation in older adults: a double-blind placebo-controlled randomized clinical trial

In this double-blind placebo-controlled randomized investigation, we assessed the tolerability of glutamine in older adults recruited from three daycare centers. The relevance of studying glutamine supplementation in elderly patients lies in its potential to provide a well-tolerated intervention. Glutamine, a crucial amino acid, plays a vital role in various physiological processes, including immune function and protein synthesis. Understanding its impact on older adults is essential, given the potential implications for their health and well-being. Participants received a daily dose of 12.4 g of oral effervescent glutamine (EGln group) or maltodextrin (placebo group) for 60 days. Fifteen patients from each group completed the study. The mean ages were 77.0±9.1 and 79.0±6.9 years for the EGln and placebo groups, respectively. We evaluated body mass index, aminogram, hemogram, plasma levels of glucose, prealbumin, albumin, urea, creatinine, uric acid, C-reactive protein, vitamin D, calcium, sodium, potassium, and the plasma activities of aspartate aminotransferase and alanine aminotransferase. Notably, we quantified a broad array of inflammatory markers and growth factors providing a holistic understanding of the potential effects of glutamine supplementation. The results demonstrated that oral glutamine did not induce significant changes in any evaluated parameters, and no adverse effects were reported. This finding suggested that the dosage of glutamine used in this study was well-tolerated and safe. This information contributes to the broader understanding of glutamine supplementation, emphasizing its safety and supporting its potential as a viable intervention for maintaining health in aging individuals.

Evaluación de las características nutricionales de alimentos y bebidas procesados publicitados en medios televisivos de Perú, 2021

El objetivo fue describir las características y el perfil nutricional de los alimentos y bebidas procesados publicitados durante el horario de protección al menor (6 am a 10 pm, según la regulación peruana) los dos canales de mayor audiencia de la televisión peruana. En este estudio transversal se grabaron 448 horas de contenido televisivo de 14 días aleatorios de 6:00 am a 10:00 pm, entre enero y febrero del 2021, donde se identificaron 2061 anuncios de alimentos y bebidas procesados. Entre 2:00 pm y 6:00 pm (33,9%) hubo mayor publicidad de alimentos. Las categorías más publicitadas fueron bebidas (41,7%) y confitería (17,8%). El 46,9% de alimentos superó al menos uno de los parámetros técnicos (azúcar total, grasas saturadas o sodio) de la primera etapa de la ley peruana y el 88,4% lo haría en la segunda etapa. La mayoría de alimentos y bebidas publicitados fueron procesados y superaban los parámetros de nutrientes críticos.

The objective was to describe the characteristics and nutritional profile of processed foods and beverages advertised during child protection hours (6 am to 10 pm, according to Peruvian regulations) on the two channels with the largest audience on Peruvian television. In this cross-sectional study, 448 hours of television content on 14 random days from 6:00 am to 10:00 pm between January and February 2021 were recorded and 2061 advertisements for processed foods and beverages were identified. The time frame with the most publicity for these foods was between 2:00 pm. and 6:00 pm. (33,9%). The most advertised categories were beverages (41,7%) and confectionery (17,8%). 46,9% of foods exceeded at least one of the technical parameters evaluated in the first stage of the Peruvian law (total sugar, saturated fat, or sodium) and 88,4% would do so in the second stage. The majority of advertised foods and beverages were processed, and most of these exceed critical nutrient parameters.

Prevalência de sarcopenia em idosos e sua associação com a ingestão de nutrientes dietéticos / Prevalence of sarcopenia in the older adults and its association with dietary nutrient intake

Este estudo teve o objetivo de verificar a prevalência de sarcopenia em idosos e sua associação com a ingestão de nutrientes dietéticos. Estudo quantitativo, transversal e analítico desenvolvido com 114 idosos adscritos em uma Unidade Básica de Saúde localizada em Mossoró (RN). A coleta foi realizada por meio de um questionário sociodemográfico, inquérito dietético, avaliação nutricional e antropométrica. Para determinação da sarcopenia, utilizou-se testes como o Timed up and go, de preensão manual e equação preditiva de massa muscular esquelética. Identificou-se prevalência de sarcopenia de 26,32%, concomitante à presença de depleção de massa muscular, baixo peso, fator de risco aumentado com o avançar da idade e desempenho físico inadequado. Constatou-se que a chance dos idosos com idade até 70 anos apresentar sarcopenia diminuiu em 73%, contraposto aos com idade acima de 70 anos e que as chances dos usuários com Timed up and go adequado apresentarem a doença diminui em 75% comparada aos participantes que apresentaram inadequação no desempenho físico. Verificou-se que os idosos sarcopênicos consu-miam quantidades reduzidas de muitos micronutrientes, como: vitamina D, E, C, B2, B3, B12, magnésio, selênio e zinco, além de apresentarem dieta inadequada em energia e proteínas, comparados aos não sarcopênicos. Ressalta-se a necessidade da expansão de conhecimentos sobre alimentação, prevenção e tratamento da sarcopenia.

This study aimed to verify the prevalence of sarcopenia in the elderly and its association with dietary nutrient intake. Quantitative, cross-sectional and analytical study developed with 114 elderly enrolled in a Basic Health Unit located in Mossoró (RN). Data were collected using a sociodemographic question-naire, dietary survey, nutritional and anthropometric assessment. To determine sarcopenia, tests such as Timed up and go, handgrip and predictive equation of skeletal muscle mass were used. A prevalence of sarcopenia of 26.32% was identified, concomitant with the presence of muscle mass depletion, low weight, increased risk factor with advancing age and inadequate physical performance. It was found that the chance of elderly people aged up to 70 years to present sarcopenia decreased by 73%, compared to those aged over 70 years and that the chances of users with adequate Timed up and go to present the disease decreased by 75% compared to participants who showed inadequate physical performance. It was found that sarcopenic elderly consumed reduced amounts of many micronutrients, such as: vitamin D, E, C, B2, B3, B12, magnesium, selenium and zinc, in addition to having an inadequate diet in terms of energy and protein, compared to non-sarcopenic individuals. It emphasizes the need to expand knowledge about food, prevention and treatment of sarcopenia.

Relação entre a alimentação e o tratamento do transtorno da ansiedade: revisão da literatura / Relationship between food and treatment of disorder anxiety: literature review

Estudos recentes evidenciam que a ansiedade é conceituada como o mal do século. De acordo com a Organização Mundial da Saúde (OMS), 18,6 milhões de brasileiros sofrem com algum distúrbio relacionado à ansiedade. A fisiopatologia da doença tem relação com a disfunção de neurotransmissores, tornando extremamente necessário o estudo dos neurotransmissores que auxiliam no combate ao transtorno da ansiedade. Realizou-se uma revisão bibliográfica sistemática observacional retrospectiva baseada em artigos científicos coletados nas bases de dados Scielo, Google Acadêmico e Biblioteca Virtual em Saúde (BVS). Uma alimentação balanceada e rica em micronutrientes fornece aos neurônios os nutrientes essenciais para a produção dos neurotransmissores responsáveis pela transmissão de mensagens cognitivas, incluindo sentimentos, emoções e pensamentos do indivíduo, podendo auxiliar significativamente na melhora do quadro de ansiedade. Os estudos levantados associam a correta ingestão de nutrientes como triptofano, vitamina D e ômega-3 como eficaz auxílio no tratamento da ansiedade. O objetivo do presente estudo é descrever a relação e eficácia do fator alimentação no tratamento do transtorno da ansiedade.

Effect of satellite-emitted frequency sequences on Phakopsora pachyrhizi control, on soybean nutrition and yield

The obstacles in Phakopsora pachyrhizi management result especially from susceptible soybean genotypes and resistant fungal strains. The objective of the current study was to evaluate the applicability of the emission of extremely low and specific frequencies by Effatha technology in the soybean Asian rust control, nutrition, and its impact on yield. The in-vivo test followed the detached leaves method, with six treatments: frequencies 1 and 2 individually and in association; the conventional chemical treatment (fungicide azoxystrobin + benzovindiflupyr); and witnesses in presence and absence of the fungus. Frequency 1 relates to inhibition of the enzyme succinate dehydrogenase and 2 to ubiquinone oxidase. In the field, frequencies 1 and 2 associated (with the same fungicidal action of the in-vivo study); nutritional frequency; application of azoxystrobin + benzovindiflupyr + mancozeb, and control without application were evaluated. In vivo, the fungicide provided 85% control of the disease symptoms, against 65% of frequencies 1 and 2 in association, which showed a higher efficiency compared to the isolated frequencies. In the field, the rate of increase of symptoms were reduced by all treatments compared to the control. At the end of the soybean cycle, the conventional fungicide resulted in 33% severity against 56% of frequencies 1 and 2 associated, and 69.2% of the control. The emission of the frequency for increased nutrient efficiency stood out positively on yield in relation to all the other ones. The conventional application provided the highest weight of 1,000 grains, possibly a direct reflection of the better control of the disease.

Descriptive analyses, association of variables with the type of vegetarianism and multinomial regression models were performed. Results A total of 232 vegetarian women were surveyed: 60.8% were between 18 and 30 years of age and belonged mainly to the middle class. According to the type of diet, 68.1% used an ovo-lacto-vegetarian diet, 18.1% were vegan, 9.0% lacto-vegetarian and 4.8% ovo-vegetarian. Among the factors evaluated in their potential relationship with the different types of vegetarianism, it is highlighted that vitamin B12 supplementation presents a statistically significant association when using veganism as a comparison category. Conclusion According to the results, among young female adults the vegetarian eating style predominates, without significant differences as to the educational level, adequate levels of physical activity in most of the population; there was a higher prevalence of ovo-lacto-vegetarianism. Vitamin B12 supplementation was significantly higher in the vegan population, indicating that ovo-lacto and ovo-vegetarian populations may be at high risk of vitamin B12 deficiency.

RESUMO Objetivo O estudo objetivou determinar a associação entre o perfil sociodemográfico e alimentar de mulheres vegetarianas em idade fértil (18 a 49 anos) na região metropolitana de Valle de Aburrá (Colômbia) em 2021-2022. Métodos Por meio de um questionário online, 232 mulheres vegetarianas e veganas em idade fértil (18 a 49 anos) pertencentes à região metropolitana de Valle de Aburrá foram entrevistadas sobre suas características sociodemográficas, tempo, tipo e motivo da escolha do vegetarianismo, atividade física, consumo de suplementos nutricionais e frequência de consumo dos grupos dos alimentos. Foi realizada análise descritiva, associação das variáveis com o tipo de vegetarianismo e modelos de regressão multinomial. Resultados Foram entrevistadas 232 mulheres vegetarianas: 60,8% tinham entre 18 e 30 anos e pertencem principalmente à classe social média. De acordo com o tipo de dieta, 68,1% tinham uma dieta ovolactovegetariana; 18,1%, vegana; 9%, lactovegetariana; e 4,8%, ovovegetariana. Entre os fatores avaliados em sua possível relação com os diferentes tipos de vegetarianismo, destaca-se que a suplementação de vitamina B12 apresenta associação estatisticamente significativa ao ter o veganismo como categoria de comparação. Conclusão De acordo com os resultados, entre mulheres adultas jovens, predomina o estilo alimentar vegetariano, sem diferença significativa observada no nível de escolaridade e níveis adequados de atividade física na maioria da população; há também maior prevalência de ovolactovegetarianismo. A suplementação de vitamina B12 é significativamente maior na população vegana, indicando um alto risco de deficiência nas populações ovolacto e ovovegetarianas.

Chewing insects, pollinators, and predators on Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) plants fertilized with dehydrated sewage sludge / Insetos mastigadores, polinizadores e predadores em plantas de Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) fertilizada com lodo de esgoto desidratado

Fertilization with dehydrated sewage sludge can speed up the recovery process of degraded areas due to nutrients concentration, favoring the development of pioneer plants such as Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) and the emergence of insects. This study aimed the evaluation of chewing, pollinating insects, predators, their ecological indices and relationships on A. auriculiformis plants fertilized with dehydrated sewage sludge. The experimental design was completely randomized with two treatments (with and without dehydrated sewage sludge) and 24 repetitions. The prevalence of chewing insects Parasyphraea sp. (Coleoptera: Chrysomelidae), Nasutitermes sp. (Blattodea: Termitidae), and Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae), defoliation, and ecological indices of abundance of Coleoptera and Orthoptera were observed on fertilized A. auriculiformis. Acacia auriculiformis plants, with a superior number of branches/tree, revealed greater abundance of Coleoptera and Orthoptera, species richness of pollinating insects, defoliation, numbers of Parasyphraea sp. and T. collaris. The ones with larger leaves/branches displayed greater abundance of species richness of Coleoptera and Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). Therefore, the use of A. auriculiformis plants, fertilized with dehydrated sewage sludge, is promising in the recovery of degraded areas due to the ecological indices increase of chewing and pollinators insects and spiders in the analyzed area.

A fertilização com lodo de esgoto desidratado pode acelerar o processo de recuperação de áreas degradadas devido à concentração de nutrientes, favorecendo o desenvolvimento de plantas pioneiras tais como Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) e de seus insetos. O objetivo deste trabalho foi avaliar os insetos mastigadores, polinizadores e predadores e seus índices e relações ecológicas em plantas de A. auriculiformis fertilizadas com lodo de esgoto desidratado, em área degradada, durante 24 meses. O delineamento foi inteiramente casualizados com dois tratamentos (com e sem adubação com lodo de esgoto desidratado) e 24 repetições (uma repetição = uma planta). O maior número de insetos mastigadores Parasyphraea sp. (Coleoptera: Chrysomelidae), Nasutitermes sp. (Blattodea: Termitidae) e Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae), de desfolha, e do índice ecológico abundância de Coleoptera e de Orthoptera foram maiores em plantas de A. auriculiformis fertilizadas do que nas não fertilizadas com lodo de esgoto desidratado. Plantas de A. auriculiformis, com maior quantidade de galhos/árvore, apresentaram maiores abundâncias de Coleoptera e Orthoptera, riqueza de espécies de insetos polinizadores, desfolha e números de Parasyphraea sp. e T. collaris, e as com maior folhas/galho os de riqueza de espécies de Coleoptera e Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). Por tanto, a utilização de A. auriculiformis, adubada com lodo de esgoto desidratado, é promissora na recuperação de áreas degradadas devido ao aumento dos índices ecológicos de insetos mastigadores, polinizadores e aranhas na área.

Coexistence of high content of critical nutrients and claims in food products targeted at Brazilian children / Coexistência de altos teores de nutrientes críticos e alegações em produtos alimentícios voltados para crianças brasileiras

ABSTRACT Objective: This study aimed to evaluate food labels targeted at children and identify the concomitant presence of claims and high levels of critical nutrients and/or the presence of sweeteners. As a secondary objective, it aimed to list different types of claims and check which marketing strategies are most used. Methods: We collected 409 products, from 8 popular food groups targeted at children, in Brazilian market (i.e., fruit drinks, dairy drinks, sandwich cookies, cakes, breakfast cereals, jellies, corn snacks, and yogurts). The contents of critical nutrients (e.g., sugar, total fat, saturated fat, and trans-fat, and sodium) and presence/absence of sweetener were calculated, considering Pan American Health Organization (PAHO) parameters. Then, we verified the presence and types of claims in these products. Results: Overall, 265 (64.7%) labels presented claims. In three of the eight categories (i.e., breakfast cereals, dairy drinks, and yogurt), all products with claims (50, 34, and 34 products, respectively) had one or more nutrients in harmful concentrations (critical nutrients above PAHO's nutritional profile and/or presence of sweeteners). In the other categories, only one product (of 63 sandwich cookies and 26 breakfast cereals with claims) and three products (of 22 cakes and 28 jellies with claims) had no nutrient in critical concentration. The presence of claims, like "rich/source" of micronutrient, was predominant in seven of the eight food groups. Conclusion: In the present study, there was a high presence of claims, of different types, in foods targeted at children, which, for the most part, also have excess of at least one critical nutrient, according to PAHO.

RESUMO Objetivo: Avaliar rótulos de alimentos direcionados ao público infantil e identificar a presença concomitante de alegações e de altos teores de nutrientes críticos e/ou presença de adoçantes. Como objetivo secundário, listar os diferentes tipos de alegações e verificar quais estratégias de marketing são mais utilizadas. Métodos: Foram coletados 409 produtos provenientes das oito categorias de alimentos mais populares entre crianças brasileiras (bebidas à base de frutas, bebidas lácteas, biscoitos recheados, bolos, cereais matinais, gelatinas, salgadinhos de milho e iogurtes). Foram calculados os teores de nutrientes críticos (açúcares, gorduras totais, saturadas e trans e sódio) e presença/ausência de adoçante, considerando-se os parâmetros da Organização Pan-Americana de Saúde (OPAS). Em seguida, verificamos a presença e os tipos de alegações nesses produtos. Resultados: No total, 265 (64,7%) rótulos apresentaram alegações. Em três das oito categorias (cereais matinais, bebidas lácteas e iogurtes), todos os produtos com alegações (50, 34 e 34 produtos, respectivamente) continham um ou mais nutrientes em concentrações prejudiciais (nutrientes críticos acima do preconizado pela OPAS e/ou presença de edulcorantes). Nas demais categorias, apenas um produto (de 63 biscoitos recheados e 26 cereais matinais com alegação) e três (de 22 bolos e 28 gelatinas com alegação) não apresentavam nutrientes em concentração crítica. A presença de alegações, como "rico" ou "fonte" de micronutriente, foi predominante em sete dos oito grupos de alimentos. Conclusões: Observou-se alta presença de alegações, de diferentes tipos, em alimentos destinados a crianças, que, em sua maioria, também possuem excesso de pelo menos um nutriente crítico, de acordo com a OPAS.
