Título: Seasonal Variation of Plant Mineral Nutrition in Fruit Trees
Fonte: Braz. arch. biol. technol;62:e19180340, 2019. tab, graf.
Idioma: en.
Resumo: Abstract This research evaluated the monthly variation of plant mineral nutrition in six species of fruit trees over a year. Leaf samples were taken from the fruit trees and nutritional status (N, P, K, Ca, Mg, Fe, Zn, Cu, Mn, and Mo) was determined in the leaves in a month basis from April until November for apple, persimmon and peach. Mandarin mineral nutrition was monitored for one year, and grape and fig from May to November. Using this data, the Diagnosis Recommendation Integrated System (DRIS) was also calculated to evaluate the nutrient balance in the plants. The concentration of N and P had seasonal differences, especially in apple and peach, which reached the peak during the summer. Apple, fig, and grape trees had large ranging on their mineral contents over the year, especially with the P and K levels reaching the minimum during the harvesting season. However, the seasonal changes in leaf micronutrient concentrations were not uniform and not affected by phenological stage. The DRIS data demonstrated that mandarin had the best nutrient balance compared to others and that K was the most limiting element among the fruit trees. In summary, the current data suggest the occurrence of a significant seasonality in mineral nutrition in these six fruit trees, especially in temperate ones.

Resumo: ABSTRACT Objective To estimate the dietary intake of cancer patients and its relation with clinical and demographic characteristics, and to assess the contribution of dietary intake, appetite/symptoms and clinical and demographic characteristics to their quality of life. Methods The consumption of energy and macronutrients of patients was estimated. The relation between dietary intake and clinical and demographic characteristics was evaluated by analysis of variance. The intake of energy and macronutrient of the patients was compared to the nutritional recommendations using 95% confidence interval. The Cancer Appetite and Symptom Questionnaire (CASQ) and the European Organization for Research and Treatment of Cancer (EORTC QLQ C-30) were used to assess appetite/symptoms and quality of life, respectively. The psychometric properties of the instruments were estimated. A structural equation model was prepared. Results In this study, 772 cancer patients (63.1% women) participated. There was a significant relation between dietary intake and work activity, economic class, specialty field of cancer, type of treatment and nutritional status. Patients' energy and macronutrients intake was below recommended values. Both CASQ and EORTC QLQ C-30 were refined to fit the data. In the structural model, impaired appetite, more symptoms, presence of metastasis, being female and of higher economic classes were characteristics that significantly contributed to interfering in patients' quality of life. Conclusion The dietary intake of oncology patients did not reach the recommended values. Different characteristics impacted on quality of life of patients and should be considered in clinical and epidemiological protocols.

RESUMO Objetivo Estimar a ingestão dietética de pacientes com câncer e sua relação com características clínicas e demográficas, além de verificar a contribuição da ingestão dietética, apetite/sintomas e características clínicas e demográficas para a qualidade de vida deles. Métodos Foi estimado o consumo de energia e de macronutrientes. A relação entre ingestão dietética e características clínicas e demográficas foi avaliada pela análise de variância. A ingestão de energia e macronutrientes dos pacientes foi comparada com a necessidade nutricional, utilizando intervalo de confiança de 95%. O Cancer Appetite and Symptom Questionnaire (CASQ) e o European Organization for Research and Treatment of Cancer (EORTC QLQ C-30) foram utilizados para avaliar apetite/sintomas e qualidade de vida, respectivamente. As propriedades psicométricas dos instrumentos foram estimadas. Elaborou-se modelo de equações estruturais. Resultados Participaram do estudo 772 pacientes oncológicos (63,1% mulheres). Observou-se relação significativa entre ingestão dietética e atividade laboral, classe econômica, especialidade do diagnóstico, tipo de tratamento e estado nutricional. O consumo de energia e macronutrientes dos pacientes esteve abaixo do recomendado. Tanto o CASQ quando o EORTC QLQ C-30 foram refinados para bom ajustamento aos dados. No modelo estrutural, comprometimento do apetite, maior acometimento por sintomas, presença de metástase, ser mulher e pertencer às classes econômicas mais altas foram características que contribuíram significativamente para o comprometimento da qualidade de vida dos pacientes oncológicos. Conclusão A ingestão dietética dos pacientes oncológicos não atingiu os níveis recomendados. Diferentes características impactaram na qualidade de vida dos pacientes e devem ser consideradas em protocolos clínicos e epidemiológicos.

Idioma: es.
Resumo: La mayoría de los estudios apoyan la tesis de que el desayuno es la comida más importante del día. Un desayuno adecuado contribuye a lograr un patrón dietético global saludable y a mejorar la calidad de la dieta. El objetivo de este estudio fue determinar los principales patrones de desayuno en tres poblaciones universitarias de España, Túnez y Estados Unidos, analizar sus semejanzas y diferencias y estudiar la influencia de factores antropométricos, sociodemográficos y de estilo de vida en la adherencia a cada patrón. Se realizó un estudio transversal con datos de 730 estudiantes matriculados en las Universidades de Castilla-La Mancha, Cartago e Internacional de Florida en 2013. El consumo de alimentos se obtuvo mediante dos recordatorios de 24 horas, no consecutivos, uno de ellos en fin de semana. Los patrones se identificaron mediante análisis factorial exploratorio. La adherencia de los estudiantes a cada patrón se evaluó usando las puntuaciones factoriales. Se obtuvieron cuatro patrones para cada país. El principal patrón de los universitarios españoles incluyó pan, tomate, sal y aceite de oliva (varianza explicada: 20,85%); el principal de los tunecinos contenía pan, mermelada, nata y mantequilla (varianza explicada: 12,73%) y el principal de los americanos incluyó huevos, leche entera y azúcares (varianza explicada: 10,77%). Género, peso, IMC o comer fuera de casa fueron factores que influyeron en la adherencia a diferentes patrones. El estudio mostró la coexistencia de patrones tradicionales con otros occidentalizados y modelos transicionales intermedios. No se determinó un patrón generalizable asociado a mejores resultados del IMC(AU)

Most studies support the conclusion that breakfast is the most important meal of the day. An adequate breakfast contributes to achieving a healthy global dietary pattern and improving quality of diet. The objective of this study was to determine the main breakfast patterns of three university populations from Spain, Tunisia, and The United States of America, analyze their similarities and differences, and study the impact of anthropometric, sociodemographic and lifestyle factors on the adherence to each pattern. A cross-sectional study was developed with data from 730 students enrolled at the University of Castilla-La Mancha, University of Carthage, and Florida International University, during 2013. Food consumption data were obtained by means of two non-consecutive 24-hour recalls including one weekend day. Exploratory factor analysis was conducted to identify breakfast patterns. Factor scores were used to assess students' adherence to each pattern. Four breakfast patterns were obtained for each country. The main pattern of the Spanish students included bread, tomato, salt, and olive oil (explained variance: 20.85%); the main model of the Tunisians included bread, jam, cream and butter (explained variance: 12.73%); and the first pattern of the Americans was characterized by eggs, whole milk and sugars (explained variance: 10.77%). Gender, weight, BMI or eating out of home were factors that influenced the adherence to different patterns. Breakfast patterns obtained in this work showed the coexistence of traditional models with westernized and transitional ones. It was not determined a generalizable pattern associated with better BMI results(AU)

Título: Fomento de alimentación laboral saludable en américa del sur / Healthy eating promotion at work
Fonte: Rev. cientif. cienc. med;23(1):61-68, 2020. ilus.
Idioma: es.
Resumo: La alimentación es un factor fundamental en la calidad de vida de los trabajadores, ya que aporta los nutrientes requeridos por el organismo para un funcionamiento apropiado. Teniendo en cuenta esto, se realizó una revisión documental de artículos científicos sobre la alimentación laboral en los países de Sur América a través de una búsqueda en las bases de datos Medline, Scielo y Ebsco en el periodo 2010 - 2019. Los artículos seleccionados fueron experiencias de programas de promoción de la alimentación saludable en el entorno laboral. En términos generales, se identificó cómo desde las acciones implementadas en el nivel individual, ambiental y organizacional aumentó el consumo de frutas y vegetales en la dieta de los trabajadores. Del mismo modo se evidencia que las experiencias de alimentación laboral saludable en América del Sur son limitadas desde el enfoque de la promoción de la salud.

Food is an important factor in the life quality of workers, since it provides the nutrients required by the body for proper functioning. Taking this into account, a documentary review of scientific articles on labor feeding in the countries of South America was carried out through a search in the Medline, Scielo and Ebsco databases, in the period 2010 - 2019. The articles selected were experiences of programs to promote healthy eating in the work environment. In general terms, it was identified how from the actions implemented at the individual, environmental and organizational level, the consumption of fruits and vegetables in the workers' diet increased. In the same way it is evident that the experiences of healthy work feeding in South America are limited from the health promotion approach. Keywords: Health promotion, Employment, Healthy Diet, Occupational Health.

Fonte: Alerta (San Salvador);4(3):142-135, jul. 29, 2021. graf, tab.
Idioma: es.
Resumo: Introducción. La dieta actual de la población se caracteriza por la sustitución de alimentos naturales por productos alimenticios procesados, formulados industrialmente con ingredientes que contienen sodio. Objetivo. Clasificar el contenido de sodio en productos alimenticios preenvasados comercializados en El Salvador, según el perfil de nutrientes de la Organización Panamericana de la Salud y las metas regionales para formulación industrial. Metodología. Diseño transversal descriptivo, se analizaron las etiquetas nutricionales de 1016 productos de siete categorías, registrados en el Sistema de Información en Salud Ambiental. Para la clasificación del contenido de sodio se aplicaron fórmulas según el perfil de nutrientes: alto en sodio ≥1 miligramo de sodio por caloría. Para la clasificación según metas regionales: cuando el contenido de sodio en 100 gramos de producto es > a la meta establecida. Resultados. Según el perfil de nutrientes, el 52% de los productos tiene alto contenido de sodio. Según metas regionales, el 24% está formulado por arriba de las metas, esto refleja diferencias entre las valoraciones de contenido de sodio por categoría. Conclusión. Más de la mitad los productos alimenticios preenvasados comercializados en El Salvador son clasificados como altos en sodio, según el perfil de nutrientes. Una cuarta parte de estos están formulados con sodio por encima de las metas regionales, mostrando que las metas son más flexibles en la valoración de contenido máximo de sodio para la formulación industrial en relación con la valoración de contenido alto en sodio para consumo humano

Introduction. The current diet of the population is characterized by the substitution of natural foods for processed food products, industrially formulated with ingredients that contain sodium. Target. Classify the sodium content in prepackaged food products marketed in El Salvador, according to the nutrient profile of the Pan American Health Organization and the regional goals for industrial formulation. Methodology. Descriptive cross-sectional design, the nutritional labels of 1016 products from seven categories, registered in the Environmental Health Information System, were analyzed. For the classification of sodium content, formulas were applied according to the nutrient profile: high in sodium ≥1 milligram of sodium per calorie. For classification according to regional goals: when the sodium content in 100 grams of product is> the established goal. Results. According to the nutrient profile, 52% of the products are high in sodium. According to regional goals, 24% is formulated above the goals, this reflects differences between the valuations of sodium content by category. Conclution. More than half of the prepackaged food products marketed in El Salvador are classified as high in sodium, according to the nutrient profile. A quarter of these are formulated with sodium above the regional goals, showing that the goals are more flexible in the assessment of maximum sodium content for industrial formulation in relation to the assessment of high sodium content for human consumption

Resumo: El amaranto, quinua y tarwi, son alimentos (cereales) de gran valor nutritivo y medicinal, consecuentemente es importante estudiar estas propiedades para el beneficio en la calidad de la alimentación (por su contenido en macronutrientes) como para la prevención de enfermedades. El desayuno como primera comida que se consume en el día cumple una función esencial, debido a que cubre las primeras necesidades nutricionales requeridas por el organismo, para la obtención de fuentes de energía, materias primas en la biosíntesis de compuestos necesarios para el sistema inmune, y otros. En este trabajo se realizó una evaluación de las propiedades nutritivas de estos productos cuando se complementan al desayuno, principalmente a través de la valoración de la ingesta calórica y los macronutrientes, medición de parámetros antropométricos y otros. Después del consumo del amaranto, quinua y/o tarwi en el desayuno en un grupo de voluntarias (estudiantes) durante 4 semanas, se observó una disminución significativa de los parámetros antropométricos relacionados con el Peso, Circunferencia de la Cintura (CCi) e Índice de masa corporal (IMC). Este estudio también reveló que, el consumo calórico (kcal/día) en el desayuno de este grupo, fue bajo y moderado con un promedio de 279,7 ± 70,9 kcal/día, equivalente al 14 % del GET (Gasto energético total). También se evidenció una pobre ingesta de hidratos de carbono, proteínas, grasas y una deficiente ingesta de fibra dietética (44,8± 14,1; 9,8 ± 3,5; 7,3 ± 2,2 y 0,04 ± 0,08 g/díarespectivamente). Efectos significativos fueron observado en el aumento del aporte calórico (57,9; 58,1 (p<0,05); 59,6 (p<0,01); Kcal/día con el amaranto, quinua y tarwi, respectivamente, así como en los macronutrientes.

Amaranth, Quinoa and Tarwi, are foods with extraordinary nutritional and medicinal properties. The study of these properties is important to improve the feed quality and prevent diseases in the population. Breakfast as the first meal consumed in the day fulfills an essential function, because it covers the first nutritional needs required by the body, for obtaining sources of energy, raw materials in the biosynthesis of compounds necessary for the immune system, and others. In this work an evaluation of the nutritional properties of these products was carried out when they complement the breakfast, mainly through the evaluation of the caloric intake and the macronutrients, anthropometric parameters measurement and others. After consumption of amaranth, quinoa and / or tarwi at breakfast in a group of volunteers (students) for 4 weeks, a significant decrease in the anthropometric parameters related to Weight, Waist Circumference (CCi) and Index of Body mass (BMI). This study also revealed that the caloric intake (kcal / day) in this group's breakfast was low and moderate with an average of 279.7 ± 70.9 kcal / day, equivalent to 14% of GET (Total Energy Expenditure). Indeed, poor dietary intake of carbohydrates, proteins, fats and fiber (44.8 ± 14.1, 9.8 ± 3.5, 7.3 ± 2.2 and 0.04 ± 0.08 g / day respectively) was evidenced. The results showed significant effects on the increase in caloric intake (57.9, 58.1 = p <0.05, 59.6 = p <0.01), Kcal/day with amaranth, quinoa and tarwi respectively, As well as in macronutrients.

Resumo: RESUMEN Una dieta vegetariana se define por la exclusión total o parcial de alimentos de origen animal. Cuando es planificada adecuadamente puede prevenir y tratar enfermedades. Sin embargo, una dieta restrictiva en ciertos alimentos debe ser evaluada. El propósito de esta investigación fue describir parámetros antropométricos, hábitos de alimentación y de estilo de vida en ovo-lácteo-vegetarianos y veganos y explorar diferencias en la ingesta de nutrientes críticos entre ambos grupos. Estudio descriptivo de corte transversal, realizado en ovo-lácteo-vegetarianos y veganos de Asunción, Paraguay, durante el 2015. Se evaluaron parámetros antropométricos,, ingesta y hábitos de estilo de vida saludable. Participaron 17 ovo-lácteo-vegetarianos y 14 veganos. El 67,7 % (n= 21) se encontró normopeso, el 29 % (n= 9) presentó exceso de peso, y el 3,2% (n=1) bajo peso. Se presentó una ingesta inferior a los requerimientos en energía, carbohidratos, proteínas y grasas en ambos grupos de vegetarianos, e ingesta muy limitada de calcio y vitamina B12 en veganos. Las mujeres presentaron ingesta muy por debajo de las recomendaciones para hierro y calcio. Ninguna mujer vegana cumplió con la recomendación dietaria de vitamina B12. Al comparar grupos, se hallaron diferencias significativas en proteínas, calcio (menor consumo en veganos) y fibra (menor en ovo-lácteo-vegetarianos). La suplementación con vitaminas y suplementos también fue muy baja. Los resultados resaltan la importancia de una evaluación constante de la ingesta de nutrientes en una dieta vegetariana, a modo de evitar deficiencias o excesos, y la insoslayable tarea del nutricionista para el asesoramiento alimentario-nutricional a los individuos que expresen interés en adoptar este tipo de dieta.

ABSTRACT A vegetarian diet is defined by the total or partial exclusion of foods of animal origin. When properly planned it can prevent and treat disease. However, a restrictive diet in certain foods must be evaluated. The purpose of this research was to describe anthropometric parameters, eating and lifestyle habits of lacto-ovo-vegetarians and vegans, and to explore differences in critical nutrient intake between both groups. We conducted a descriptive cross-sectional study, carried out among lacto-ovo-vegetarians and vegans in the city of Asunción, Paraguay, during 2015. Anthropometric parameters,, intake and healthy lifestyle habits were evaluated. Seventeen lacto-ovo-vegetarians and 14 vegans participated. 67.7% (n= 21) were normal weight, 29.1% (n= 9) were overweight, and 3.2% (n= 1) were underweight. There was an intake lower than the requirements in terms of energy, carbohydrates, proteins and fats in both groups of vegetarians, and very limited intake of calcium and vitamin B12 in vegans. Women particularly had intake well below the recommendations for iron and calcium. No woman on a vegan diet met the dietary recommendation for vitamin B12. When comparing groups, significant differences were found in terms of protein and calcium, (lower consumption in vegans), fiber (lower in lacto-ovo-vegetarians). Vitamin supplementation was also very low. The results highlight the importance of constant evaluation of nutrient intake in a vegetarian diet in order to avoid deficiencies or excesses, and the very important work of the nutritionist for food and nutritional advice for individuals who express interest in adopting this type of diet.

Resumo: Objetivo: quantificar a abundância e a biomassa de moluscos bentônicos no Lago Igapó I, Londrina, Paraná, Brasil. Material e Métodos: foram realizadas duas coletas no Lago Igapó I, a primeira em junho de 2015 e a segunda em fevereiro de 2016. O substrato (incluindo os moluscos incrustados) foi amostrado utilizando um quadrante com área de 1 m2, onde 10 amostragens foram realizadas entre três pontos distintos do lago. Os moluscos capturados foram anestesiados e eutanasiados por superexposição ao gelo. Posteriormente, o material foi quantificado em abundância (n) e biomassa total (kg), e armazenado em tambores contendo formol 4% tamponado com carbonato de cálcio. Resultados: foram identificadas cinco espécies de moluscos, sendo três não nativas (Limnoperna fortunei, Corbicula fluminea e Melanoides tuberculata), uma nativa (Aylacostoma cf. tenuilabris) e um indivíduo do gênero Pomacea. Em ambas as coletas, L. fortunei compreendeu aproximadamente 90% da abundância e biomassa total. A partir da densidade média de L. fortunei e a área total do Lago Igapó I, estimou-se que a população total de mexilhões-dourados pode chegar a 633 milhões de indivíduos, correspondendo a 638 toneladas de biomassa. Conclusão: é evidente a dominância da espécie invasora L. fortunei no Lago Igapó I, onde esta pode causar diversos efeitos negativos, como alterações no ciclo de nutrientes, redução de espécies nativas, introdução de parasitos, bioacumulação de metais pesados na cadeia trófica, diminuição da qualidade da água para uso humano e obstrução de encanamentos com risco de alagamentos. Desta forma, recomenda-se uma imediata ação de manejo neste ambiente para retirada de indivíduos da espécie, com consequente redução de sua abundância.(AU)

Objective: quantify the abundance and biomass of benthic molluscs in Igapó Lake I, Londrina, Paraná, Brazil. Material and Methods: two samplings was made at Igapó Lake I, first in June 2015 and then in February 2016. The substrate (including all embedded molluscs) was sampled using a 1 m2 quadrant, where 10 samples were taken between three distinct points from the lake. All molluscs captured were anesthetized and euthanized by overexposure to ice. Subsequently, the material was quantified in quantity (n) and total biomass (kg), and stored in barrels containing 4% formaldehyde buffered with calcium carbonate. Results: five species of molluscs were identified, three non native species (Limnoperna fortunei, Corbicula fluminea and Melanoides tuberculata), one native (Aylacostoma cf. tenuilabris) and one Pomacea sp. In both sampling, L. fortunei comprised approximately 90% of the abundance and total biomass. From the average density of L. fortunei and the total area of the Igapó Lake I, it was estimated that the total population of golden mussels can reach 633 million individuals, corresponding to 638 tons of biomass. Conclusion: the dominance of the invasive species L. fortunei in Igapó Lake I is evident, where it can cause several negative effects, such as alterations in the nutrient cycle, reduction of native species, introduction of parasites, bioaccumulation of heavy metals in the food chain, decreased quality of water for human use and obstruction of pipes obstruction with risk of overflow. Therefore, we recommend an immediate management action in this environment in order to remove individuals of this species and, consequently, to reduce its abundance. (AU)

Idioma: es.
Resumo: Background: Fat-mass-associated-gene (FTO) is associated with higher energy intake and specific food preferences. Aim: To investigate the association of the FTO genotype with energy intake, macronutrient and alcohol consumption. Material and Methods: Four hundred and nine participants of the GENADIO (Genes, Environment, Diabetes and Obesity) study were included. Energy intake, macronutrient and alcohol consumption were the outcomes of interest. The association of FTO (rs9939609) genotype with these outcomes was investigated using linear regression analyses, adjusting for confounding variables. Results: After adjusting for socio-demographic factors, being a carrier of the risk allele for the FTO gene was associated with a higher energy intake (173 kcal per each extra copy of the risk variant [95% confidence intervals (CI): 45; 301], (P = 0.008). After adjusting for lifestyle factors and body mass index, the association was slightly attenuated but remained significant (144 kcal [95% CI: 14; 274], p = 0.030). Conclusions: The FTO genotype is associated with a higher energy intake.

Resumo: Abstract The present study was performed to assess the proximate and nutrient content of rainbow trout flesh, cultured in the Doi Inthanon Fisheries Research Unit, Chiang Mai Inland Fisheries Research and Development Center, Thailand. 240 fish were randomly distributed across 12 cages with 20 fish cage-1. Sixteen individual fish from each cage were randomly collected at different ages of 10, 12 and 24 months. Body composition, pH, water-holding capacity, shear force, collagen content analysis, sensory, lipid oxidation, and fatty acids profile were evaluated. The results indicated that body composition and carcass length were significantly higher in fish aged 24 months, except for carcass and viscero-somatic index percentages (P ≤ 0.05). Fish at 24 months showed significantly higher pH, moisture, fat, shear force, thiobarbituric acid reactive substances, and total collagen content values than fish at 10 and 12 months (P ≤ 0.05). However, protein percentage, sensory measurement and water-holding capacity were significantly higher in younger fish at 10 and 12 months. The average lipid content and n-6/n-3 ratios were significantly greater in fish at 12 months and in ventral fillets (P ≤ 0.05). However, polyunsaturated fatty acids: saturated fatty acid ratio was higher in fish at 24 months and in dorsal fillets. In conclusion, rainbow trout cultured in sub-tropical, montane conditions can be valuable sources of protein, unsaturated fatty acids, eicosapentaenoic acids, and docosahexaenoic acids.
