ABSTRACT

This study aimed to assess the impact of two commercial Saccharomyces cerevisiae strains (CHY1 and CHY2) on the intestinal health and performance of weaned piglets challenged with enterotoxigenic Escherichia coli during the nursery phase. One hundred ninety-two piglets with an average weight of 6.70 ± 0.92 kilograms were allocated in a randomized block design to one of four treatments: a negative control (C) without E. coli challenge and no yeast supplementation; a positive control (CH) with E. coli challenge and no yeast supplementation; and two treatment groups receiving an E. colichallenge with a CHY1 and CHY2 yeast strain supplementation. The challenge involved inoculating piglets with two dosages of E. coli F4 (106 CFU/ml and 109 CFU/ml) and a saline solution for the C group. Samples of intestinal tissue, blood, and cecal content were collected on the trial's 11th, 28th, and 42nd days. All variables were subjected to analysis of variance, and upon detecting significant differences via the F-test (p < 0.05), Tukey's test was applied to compare treatment means. For the analysis of diarrhea occurrence, the Kruskal-Wallis test was applied. When variables were rejected at a 5% probability level, a Dunn's test was conducted as a post-hoc analysis for paired multiple comparisons (p < 0.05), with statistical significance set at this level. Weaned piglets supplemented with CHY1 exhibited superior performance metrics, including higher average daily gain (15.3% increase), body weight (3.4% increase), feed-to-gain ratio (9.5% increase), and average daily feed intake (12.3% increase) at 28 days compared to the CH group across two different nutritional phases. No discernible effects were observed on measuring blood parameters, intestinal morphology, or cecal short-chain fatty acids. Both yeast-treated groups displayed improved performance during the most challenging periods. However, the CHY1 yeast strain contributed to enhanced piglet performance in the initial 28 days without inducing changes in intestinal morphology.(AU)


O presente estudo teve como objetivo avaliar duas cepas comerciais de Saccharomyces cerevisiae (designadas como CHY1 e CHY2) sob a saúde intestinal e desempenho de leitões desmamados desafiados com Escherichia coli enterotoxigênica durante a fase de creche. Um total de 192 leitões com peso médio 6,70 ± 0.92 quilogramas foram distribuídos em um delineamento em blocos casualizados com quatro tratamentos: um controle negativo (C) sem desafio de E. coli e sem suplementação da levedura; um controle positivo (CH) com desafio de E. coli e sem a suplementação da levedura; e dois grupos com a suplementação das dietas com as cepas comerciais das leveduras intituladas CHY1 e CHY2, juntamente ao desafio de E. coli. O desafio envolveu a inoculação de duas doses de E. coli F4 (106 UFC/ml e 109 UFC/ml) nos leitões e uma inoculação de solução salina para o grupo C. Amostras de tecido intestinal, sangue e conteúdo cecal foram coletadas nos 11º, 28º e 42º dias do experimento. Todas as variáveis foram submetidas a análise de variância e quando detectada diferença significativa pelo teste de F (p<0,05), o teste de Tukey foi aplicado para comparar as médias. Para a avalição da ocorrência de diarreia, o teste de Kruskal-Wallis foi aplicado e quando as variáveis foram rejeitadas ao nível de 5% de probabilidade, o teste de Dunn foi conduzido como uma análise post-hoc para comparações múltiplas (p<0,05) com significância estatística nesse nível. Leitões desmamados suplementados com CHY1 apresentaram métricas de desempenho superiores, incluindo maior ganho de peso diário (aumento de 15.3%), peso vivo (aumento de 3.4%), consumo de ração diário (aumento de 9.5%) e melhor eficiência alimentar (aumento de 12.3%) até os 28 dias de experimento em comparação com o grupo CH. Não foram observados efeitos dos tratamentos sobre os parâmetros sanguíneos mensurados, morfologia intestinal ou ácidos graxos de cadeia curta presentes no conteúdo cecal. Ambos os grupos tratados com leveduras apresentaram melhor desempenho durante os períodos mais desafiadores. No entanto, a cepa de levedura CHY1, especificamente, contribuiu para um melhor desempenho dos leitões nos primeiros 28 dias, sem induzir alterações na morfologia intestinal.(AU)

ABSTRACT

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.

ABSTRACT

El suero lácteo y la moringa poseen alto valor nutricional; sin embargo, su uso en la elaboración de productos alimenticios es una alternativa viable pero poco utilizada. Objetivo. Elaborar una galleta fortificada por sustitución parcial de harina de moringa (HM) y polvo de suero lácteo (PSL). Materiales y métodos. Durante septiembre-diciembre 2021, se desarrollaron cuatro formulaciones con sustitución parcial de harina de trigo por HM y PSL (F0=100:0:0; F1=90:5:5; F2=80:10:10; F3=70:15:15). La aceptación del producto se determinó mediante una evaluación sensorial considerando los atributos sabor, olor, color, textura y aceptación general. Se realizó el análisis químico proximal a la HM, al PSL, a la formulación de mayor aceptación y a F0. Se compararon los distintos parámetros químico proximales y de aceptación mediante una anova de una vía, seguido de una prueba de comparación de medias de Tukey (p<0,05). Resultados. Conforme se incrementa el porcentaje de sustitución de harina de trigo por HM y PSL se obtiene menor aceptación de las galletas, siendo F1 la más aceptada. F1 registró un contenido proteico de 6,90±0,04%, significativamente mayor al observado en F0. Conclusiones. La buena aceptabilidad de F1 indica que la sustitución parcial por HM y PSL no influyen en su aceptación; además, F1 mostró un enriquecimiento de proteinas, lípidos y cenizas, así como contenido adecuado de humedad y carbohidratos(AU)


Introduction. Whey and moringa have high nutritional value; however, their use in the production of food products is a viable but rarely used alternative. Objective. To make a biscuit fortified by partial substitution of moringa flour (MF) and whey powder (WP). Materials and methods. During September-December 2021, four formulations were developed with different degrees of partial substitution of wheat flour for MF and WP (F0=100:0:0; F1=90:5:5; F2=80:10:10; F3=70:15:15). The acceptance of the product was determined through a sensory evaluation considering the attributes taste, odor, color, texture and general acceptance. A proximal chemical analysis was performed on the MF, WP, the most widely accepted formulation and F0. Proximal chemical parameters and acceptance attributes were compared using a one-way anova, followed by a Tukey mean comparison test (p<0.05). Results. As the percentage of substitution of wheat flour by MF and WP increases less acceptance of the biscuits is obtained, with F1 as the most accepted formulation. F1 registered a protein content of 6.90±0.04%, significantly higher than that observed in F0. Conclusions: The good acceptability of F1 indicates that the partial substitution of wheat flour for MF and WP do not influence its acceptance; in addition, F1, showed an enrichment of protein, lipid and ash, as well as adequate moisture and carbohydrate content(AU)

ABSTRACT

ANTECEDENTES: En el marco de la metodología ad hoc para evaluar solicitudes de tecnologías sanitarias, aprobada mediante Resolución de Instituto de Evaluación de Tecnologías en Salud e Investigación N° 111-IETSI-ESSALUD-2021, se ha elaborado el presente dictamen, el que expone la evaluación de la eficacia y seguridad de la fórmula nutricional con bajo contenido lipídico y alto en triglicéridos de cadena media (TCM) en pacientes pediátricos con quilotórax. Así, el médico Marco Morales Acosta, especialista en pediatría, del Servicio de Pediatría Clínica del Hospital Nacional Edgardo Rebagliati Martins, perteneciente a la Red Prestacional Rebagliati, siguiendo la Directiva N.° 003-IETSIESSALUD-2016, envió al Instituto de Evaluación de Tecnologías en Salud e Investigación - IETSI la solicitud de uso, por fuera del petitorio del producto: fórmula nutricional con bajo contenido lipídico y alto en TCM. ASPECTOS GENERALES: El quilotórax es la acumulación de líquido linfático en la cavidad pleural, que resulta de fugas provenientes de los vasos linfáticos (Tutor, 2014). El quilotórax se diagnostica tras la detección de concentración de triglicéridos en el líquido pleural mayor a 110 mg/dl (Rocha et al., 2006). En la población pediátrica, el quilotórax es causado, principalmente, por defectos congénitos o por daños al conducto torácico como resultado de complicaciones posquirúrgicas (Soto-Martinez & Massie, 2009). La incidencia aproximada del quilotórax congénito es de 1 por cada 10,000 nacidos vivos (Zheng et al., 2020); mientas que, la incidencia del quilotórax post-cirugía cardíaca en población pediátrica varía de 0.85 % a 9.2 % (Rocha et al., 2006). A pesar de no tener alta incidencia, los pacientes menores de 18 años con quilotórax tienen riesgo de mortalidad de hasta el 50 % cuando no reciben tratamiento, mayor morbilidad y tienen mayor tiempo de estancia hospitalaria (mediana = 38.8 días; rango intercuartil [R1Q) = 27.8 - 52.3, frente a mediana = 27.0 días, RIQ = 18.9 - 39.1 días; p < 0.001), comparado con los que no desarrollaron quilotórax luego de una cirugía cardiaca (Bai et al., 2021; Yeh et al., 2013). METODOLOGÍA: Se llevó a cabo una búsqueda bibliográfica exhaustiva con el objetivo de identificar la mejor evidencia disponible sobre la eficacia y seguridad de la fórmula con bajo contenido lipídico y alto contenido de TCM. La búsqueda bibliográfica se realizó en las bases de datos bibliográfica de PubMed, The Cochrane Library y LILACS. Asimismo, se realizó una búsqueda manual dentro de las páginas web pertenecientes a grupos que realizan evaluación de tecnologías sanitarias (ETS) y guías de práctica clínica (GPC) incluyendo la World Health Organization (WHO), la National Institute for Health and Care Excellence (NICE), la Agency for Healthcare Research and Quality's (AHRQ), la Scottish Intercollegiate Guidelines Network (SIGN), la New Zealand Guidelines Group (NZGG), la National Health and Medical Research Council (NHMRC), el Instituto de Evaluación de Tecnologías en Salud e Investigación (IETSI), el Centro Nacional de Excelencia Tecnológica en Salud (CENETEC), la Canadian Agency for Drugs and Technologies in Health (CADTH), el Institute for Quality and Efficiency in Health Care (IQWIG), el Scottish Medicines Consortium (SMC), la Comissáo Nacional de Incorporção de Tecnologias no Sistema Único de Saúde (CONITEC), el Instituto de Evaluación Tecnológica en Salud (IETS) y el Instituto de Efectividad Clínica y Sanitaria (IECS). Finalmente, se realizó una búsqueda adicional en la página web de registro de ensayos clínicos (EC) www.clinicaltrials.gov, para identificar EC en curso o que no hayan sido publicados aún. RESULTADOS: Luego de la búsqueda bibliográfica, no se encontró alguna GPC, ETS o ECA fase III que cumpla con los primeros criterios de inclusión. Tras la ampliación de los criterios de elegibilidad, se incluyeron tres estudios observacionales (Bellini et al., 2012; Cormack et al., 2004; Zheng et al., 2020). Dos de estos estudios (Cormack 2004 & Zheng 2020), usaron el diseño de cohortes de tipo retrospectivo, y compararon el tiempo hasta la resolución del quilotórax (solo en Zheng et al 2020), duración de drenaje pleural (solo en Cormack et al 2004), tiempo de hospitalización y mortalidad en los pacientes con quilotórax posquirúrgico que usaron la fórmula con bajo contenido lipídico alto en TCM versus los que usaron la NPT. El último estudio (Bellini et al 2012), se trata de una serie de casos de neonatos con quilotórax congénito, donde se reporta la experiencia de tratamiento de estos pacientes usando la fórmula nutricional con bajo contenido lipídico y alto en TCM con o sin la octreotida. Los desenlaces de interés evaluados fueron la resolución del quilotórax y la mortalidad. CONCLUSIÓN: Por lo expuesto, el Instituto de Evaluación de Tecnologías en Salud e Investigación aprueba el uso de la fórmula con bajo contenido lipídico y alto en TCM, con o sin octreotida, en pacientes menores de 18 años con diagnóstico de quilotórax debido a cualquier etiología (congénito o adquirido) que pueden recibir nutrición enteral, como producto farmacéutico no incluido en el Petitorio Farmacológico de EsSalud, según lo establecido en el Anexo N° 1. La vigencia del presente dictamen preliminar es de un año a partir de la fecha de publicación. Así, la continuación de dicha aprobación estará sujeta a la evaluación de los resultados obtenidos y de mayor evidencia que pueda surgir en el tiempo.

ABSTRACT

Folic acid belongs to the group of water-soluble B vitamins and naturally exists in multiple forms in a wide variety of foods such as legumes, vegetables, liver, and milk (Iyer and Tomar, 2009; Lyon et al., 2020). It is involved in many biochemical reactions critical for cell division, such as purine and pyrimidine biosynthesis, DNA/RNA biosynthesis, and amino acid metabolism (Iyer and Tomar, 2009). Mammals cannot synthesize folic acid and thus they must acquire it from food. Although folic acid is ubiquitous in foods, folic acid deficiency still often occurs due to various causes such as unhealthy diet (Hildebrand et al., 2021; Iimura et al., 2022), disease-related malabsorption (Arcot and Shrestha, 2005), medication-related depletion (Arcot and Shrestha, 2005), or vitamin B12 deficiency (Fishman et al., 2000). Folic acid deficiency has been associated with several health problems, such as anemia (Carmel, 2005; Bailey and Caudill, 2012), cancer (Duthie, 1999), cardiovascular diseases (Wald et al., 2002), neural tube defects in newborns (van der Put et al., 2001), neuropsychiatric dysfunction (Shea et al., 2002), depression (Falade et al., 2021), inflammatory diseases (Suzuki and Kunisawa, 2015; Jones et al., 2019), and eye diseases (Sijilmassi, 2019). To prevent folic acid deficiency, its daily intake (400 μg/d) has been recommended for adults in the European Union, and its increased intake (600 μg/d) is advised for women before and during pregnancy (FAO/WHO, 2002; IOM, 2004). The New Zealand government mandated the fortification of non-organic wheat flour with folic acid in July 2021, and the UK government mandated the fortification of non-wholemeal wheat flour with folic acid in September 2021 (Haggarty, 2021).

ABSTRACT

Introducción. El enriquecimiento de la harina de trigo es una de las estrategias de salud pública recomendadas para prevenir las deficiencias de micronutrientes, entre ellos el hierro. El objetivo de este trabajo fue determinar el contenido de hierro en harina de trigo enriquecida y sus derivados, y la contribución de estos a las recomendaciones nutricionales en niños. Población y métodos. Estudio observacional, analítico, de corte transversal, basado en la metodología de estudio de dieta total. Se analizaron la harina de trigo enriquecida (según la ley 25630) y sus derivados más consumidos. Para seleccionar los alimentos, se realizó un cuestionario de frecuencia de consumo y recordatorio de 24 horas a los padres de niños con edades entre 6 meses y 7 años. Se determinó la concentración de hierro en los alimentos mediante absorción atómica y se evaluó su contribución al requerimiento promedio estimado. Resultados. La harina enriquecida y sus derivados tuvieron la cantidad de hierro esperada, excepto el pan francés y el pan rallado. La contribución a los requerimientos de hierro de los alimentos evaluados fue el 7 % en niños de 6 meses a 1 año, el 81 % en el grupo de 1 a 3 años y el 45 % en los mayores de 4 años. Conclusiones. Excepto el pan francés y el pan rallado, las harinas y sus derivados analizados presentaron el nivel de enriquecimiento esperado. El consumo de estos alimentos no aporta cantidades significativas de hierro en los lactantes, pero sí en los niños mayores de 1 año.


Introduction. Wheat flour enrichment is a public health strategy recommended to prevent micronutrient deficiencies, including iron deficiency. The objective of this study was to determine iron content in enriched wheat flour and flour products and their contribution to nutritional recommendations for children. Population and methods. Observational, analytical, cross-sectional study based on the total diet study method. Enriched wheat flour (as per Law no. 25630) and the most frequently consumed flour products were analyzed. Products were selected using a questionnaire on the frequency of food intake and a 24-hour recall interview with the parents of children aged 6 months to 7 years. Food iron levels were determined based on atomic absorption spectrometry and their contribution to the estimated average requirement was assessed. Results. Enriched flour and flour products showed the expected iron amount, except for French bread and breadcrumbs. The contribution of studied products to iron requirements was 7 % in children aged 6 months to 1 year, 81 % in those aged 1-3 years, and 45 % in those older than 4 years. Conclusions. Except for French bread and breadcrumbs, studied flour and flour products showed the expected enrichment level. The consumption of this type of food does not provide significant amounts of iron to infants, but it does to children older than 1 year.

ABSTRACT

En esta investigación documental se presentan alternativas viables para utilizar cabezas de pescado, subproductos de la acuicultura, para elaborar harina que sirva como materia prima para la fortificación de productos alimenticios nutritivos. La harina de cabeza de pescado propuesta en esta investigación puede ser integrada exitosamente a alimentos para consumo humano, y usadas en las proporciones adecuadas no causa interferencias en las propiedades sensoriales de los productos formulados. Para masificar la producción de los alimentos fortificados con harina de cabeza de pescado propuestos en este estudio, es indispensable practicarle además una serie de pruebas denominadas "vida de anaquel".


In this documentary research, viable alternatives are presented to use fish heads, by-products of aquaculture, to make flour that serve as raw material for the fortification of nutritious food products. The fish head meal proposed in this research can be successfully integrated into food for human consumption, and used in the appropriate proportions does not cause interference in the sensory properties of the formulated products. To massify the production of foods fortified with fish head meal proposed in this study, it is essential to also perform a series of tests called "shelf life".

ABSTRACT

ABSTRACT Objective: To carry out a systematic review on the effects of phytosterol supplementation on the treatment of dyslipidemia in children and adolescents. Data sources: Review in the SciELO, Lilacs, Bireme, PubMed and Web of Science databases, with no time limit. Descriptors: phytosterols or plant sterols and dyslipidemias, hypercholesterolemia, cholesterol, children, adolescent, in English and Portuguese. The articles included were published in Portuguese, English or Spanish and evaluated the effect of phytosterol supplementation in pediatric patients with dyslipidemia. Documents that involved adults or animals, review papers, case studies and abstracts were excluded. Two authors performed independent extraction of articles. Of 113 abstracts, 19 were read in full and 12 were used in this manuscript. Data synthesis: Phytosterol supplementation to reduce cholesterol levels has been shown to be effective in reducing LDL-cholesterol levels by approximately 10%, with reductions above 10% in LDL-cholesterol levels observed after 8 to 12 weeks of intervention. Studies have not shown significant changes in HDL-cholesterol and triglyceride levels. Based on the absence of adverse effects, its use seems to be safe and of good tolerance in children and adolescents. Conclusions: Phytosterol supplementation seems to be of great therapeutic aid for the treatment of hypercholesterolemia in children and adolescents. Further studies assessing the long-term effect of phytosterol supplementation are necessary.


RESUMO Objetivo: Realizar uma revisão sistemática sobre os efeitos da suplementação de fitoesteróis no tratamento da dislipidemia em crianças e adolescentes. Fontes de dados: Revisão nos bancos SciELO, Lilacs, Bireme, Pubmed e Web of Science, sem limite de tempo. Descritores: phytosterols or plant sterols, dyslipidemias, hypercholesterolemia, cholesterol, children, adolescent, nas línguas inglesa e portuguesa. Os artigos incluídos foram publicados nos idiomas português, inglês ou espanhol e avaliaram o efeito da suplementação de fitoesteróis em pacientes pediátricos com dislipidemia. Estudos que envolviam adultos ou animais, trabalhos de revisão, estudos de caso e resumos foram excluídos. A extração independente de artigos foi realizada por dois autores. Do total de 113 resumos, 19 foram lidos na íntegra, e 12 utilizados neste manuscrito. Síntese de dados: A suplementação de fitoesteróis para a redução dos níveis de colesterol mostrou-se eficiente, de forma a promover a redução de aproximadamente 10% dos níveis de LDL-colesterol, sendo observadas reduções acima de 10% em 8 a 12 semanas de intervenção. Os estudos não mostraram alterações significantes nos níveis de HDL-colesterol e triglicérides. Com base na ausência de efeitos adversos, seu uso parece ser seguro e de boa tolerância em crianças e adolescentes. Conclusões: A suplementação com fitoesteróis parece ser de grande auxílio terapêutico para o tratamento da hipercolesterolemia em crianças e adolescentes. São necessários mais estudos que avaliem o efeito em longo prazo da suplementação de fitoesteróis.

ABSTRACT

Introducción. La fortificación y suplementación son estrategias para la prevención de carencias de micronutrientes. El objetivo fue describir la procedencia de la ingesta del hierro y ácido fólico a lo largo del ciclo vital de la población de la Ciudad Autónoma de Buenos Aires. Población y métodos. Análisis de la información de la Primera Encuesta Alimentaria y Nutricional de la Ciudad Autónoma de Buenos Aires 2011, que tomó una muestra probabilística por conglomerados. El consumo se recabó con recordatorio de 24 horas. Se calculó el aporte de hierro y ácido fólico, y se categorizó en contenido natural, harina de trigo enriquecida, leche del Plan Materno Infantil, alimentos fortificados y suplementos. Resultados. De los 5369 individuos evaluados, prácticamente, la totalidad obtenía hierro y ácido fólico de contenido natural (el 58 % y el 29 % del consumo, respectivamente). Más del 90 % consumía harina de trigo enriquecida, que aportaba el 28 % del hierro y el 54 % del ácido fólico. Los alimentos fortificados mostraron consumo y aporte muy variable. La leche del Plan Materno Infantil mostró muy baja participación, inclusive en grupos específicos. El aporte de suplementos fue bajo, excepto en < 2 años (el 30 % consumía suplementos de hierro, que aportaban el 38 % de este).Conclusión. Además del aporte natural de los alimentos, la harina de trigo enriquecida representó una importante contribución en el consumo de ácido fólico y hierro de esta población; los alimentos fortificados y los suplementos tuvieron una participación diferente según el grupo etario.


Introduction. Fortification and supplementation are two strategies for micronutrient deficiency prevention. The objective of this study was to describe the source of iron and folic acid intake throughout the life cycle in the population of the Autonomous City of Buenos Aires.Population and methods. Analysis of the information collected in the First Survey on Nutritional Food Intake of the Autonomous City of Buenos Aires (2011), which had a probability cluster sampling design. Consumption was assessed by means of a 24-hour recall. Iron and folic acid intake was estimated and categorized into natural content, enriched wheat flour, milk from the Maternal and Child Plan, fortified foods, and supplements.Results. Out of the 5369 studied individuals, practically all got iron and folic acid from natural contents (58 % and 29 % of intake, respectively). More than 90 % consumed enriched wheat flour, which provided 28 % of iron and 54 % of folic acid. Fortified food consumption and intake varied greatly. Milk intake from the Maternal and Child Plan was small, even in specific groups. Intake from supplements was low, except in children < 2 years old (30 % consumed iron supplements, which accounted for 38 % of iron).Conclusion. In addition to natural intake from foods, enriched wheat flour accounted for a major source of folic acid and iron in this population; intake from fortified foods and supplements varied by age group.

ABSTRACT

The addition of different oil blends in the feed of finishing pigs was evaluated. Twenty-four castrated male finishing pigs were used in a randomized block design containing four treatments and six replicates. The treatments consisted of: Reference ration (RR) - 100% soybean oil feed; and the combination of the different oils: Blend1 - 50.0% soybean oil (SO), 25.0% flaxseed oil (FO), 12.5% olive oil (OO) and 12.5% canola oil (CO); Blend2 - 25.0% SO, 50.0% FO, 12.5% OO and 12.5% CO; and Blend3 - 25.0% SO, 12.5% FO, 12.5% OO and 50.0% CO. The performance, quantitative and qualitative carcass parameters, fatty acids profile and economic feasibility of the diets were evaluated. The use of blends in the diets did not influence the performance or carcass quality, but increased marbling and carcass yield. The fatty acid profile of the loin presented greater amounts of stearic acid in Blend3 and higher percentage of unsaturated fatty acids in animals fed with Blend1. The fatty tissue presented greater amounts of myristic acid in Blend1 and oleic acid in Blend3. The reference ration was the most economic. The Blends did not affect performance or carcass characteristics and improved the fatty acid profile.(AU)


Foi avaliada a utilização de diferentes blends de óleo em dietas de suínos em terminação. Foram utilizados 24 suínos, machos, castrados, distribuídos em delineamento de blocos ao acaso, com quatro tratamentos e seis repetições. Os tratamentos consistiram de: ração referência (RR) - 100% de ração com utilização de óleo de soja; e a combinação de diferentes óleos: Blend1 - 50,0% de óleo de soja (OS), 25,0% de óleo de linhaça (OL), 12,5% de óleo de oliva (OO) e 12,5% de óleo de canola (OC); Blend2 - 25,0% OS; 50,0% OL; 12,5% OO e 12,5% OC; e Blend3 - 25,0% OS; 12,5% OL; 12,5% OO e 50,0% OC. Foram avaliados os parâmetros de desempenho, a qualidade de carcaça, o perfil de ácidos graxos e a viabilidade econômica. O uso de blends nas dietas não influenciou o desempenho ou a qualidade da carcaça, mas aumentou o marmoreio e o rendimento de carcaça. O perfil de ácidos graxos do lombo apresentou maiores quantidades de ácido esteárico com a utilização do Blend3 e maior porcentagem de ácidos graxos insaturados nos animais alimentados com o Blend1. O tecido adiposo apresentou maiores quantidades de ácido mirístico quando se forneceu o Blend1 e de ácido oleico com o Blend3. A ração testemunha foi a mais econômica. As misturas não afetaram o desempenho e as características de carcaça e melhoraram o perfil de ácidos graxos da carne.(AU)

ABSTRACT

La inadecuación de micronutrientes es frecuente en los países en vías de desarrollo. En Costa Rica existe poca información acerca de la ingesta de micronutrientes y del impacto de los programas de fortificación obligatoria de alimentos. El objetivo de este estudio fue evaluar la ingesta de vitaminas y minerales y el aporte de la fortificación de alimentos a la ingesta total de micronutrientes en la población urbana costarricense. Se analizó el consumo de alimentos en una muestra de la población urbana costarricense, participantes del Estudio Latinoamericano de Nutrición y Salud (ELANS). El riesgo de ingesta inadecuada se estimó según sexo y grupo de edad, utilizando el método de punto de corte del Requerimiento Medio Estimado (EAR). Para el hierro, se utilizó el método de aproximación probabilística. Más del 85% de la muestra presentó riesgo de ingesta inadecuada para vitamina E, calcio y vitamina D. Una menor prevalencia de riesgo de ingesta inadecuada se presentó para la niacina, tiamina, folatos, hierro y selenio. La fortificación de alimentos tiene un efecto notorio en la ingesta de micronutrientes, especialmente de hierro, niacina, tiamina y folatos. La ingesta de calcio, vitamina D y vitamina E es preocupantemente inadecuada, siendo las mujeres y las personas mayores de 50 años los grupos más afectados. Resulta fundamental el establecimiento de programas y políticas públicas para asegurar el cumplimiento del requerimiento establecido para los diferentes micronutrientes(AU)


Micronutrient deficiencies are still very common in developing countries. In Costa Rica there is little information on micronutrients intake and the impact of food fortification.This study aimed to determine the contribution of food fortification to the total intake, and to estimate the risk of inadequate intake of vitamins and minerals in an urban Costa Rican population. As a part of the Latin American Nutrition and Health Study, we analyzed data from a nationally representative sample of 798 urban residents from Costa Rica (15-65 years old) whom provided two 24-h dietary recalls. The prevalence of inadequate micronutrient intake was estimated according to the EAR cut-point method. Iron was analyze using the probability approach. We observed a 100% of the sample are at risk of inadequate intake of vitamin D, and similar percentages were obtained for calcium and vitamin E, ranging from 92.9 to 100% and 85.5 to 99.2% respectively. A lower risk of inadequate intake was observed for niacin, thiamin, folate, iron and selenium. Food fortificationmakes an important contribution to folate, thiamin, iron and niacin intake. Despite the efforts that have been made to ensure adequate micronutrient intake in Costa Rica, the intake of calcium, vitamin D and vitamin E is still very low, especially among women and people over 50 are the most affected. Based on the above, it is recommended to promote a healthy diet through nutritional education as part of public health policies, in order to facilitates compliance to nutritional requirement(AU)

ABSTRACT

Resumen: Objetivo: Analizar la asociación entre el consumo de suplementos o leche Liconsa y anemia, deficiencias de zinc (DZ) y hierro (DH) y morbilidad en niños mexicanos residentes de localidades menores a 100 000 habitantes. Material y métodos: Se analizó información de 1 516 niños de 1 a 4 años de la Encuesta Nacional de Salud y Nutrición en localidades con menos de 100 000 habitantes realizada en el año 2018. Se definió Anemia si [Hb]<11 g/dL, DZ: [Zn]<65 µg/dL y DH: [ferritina]<12 µg/L. El consumo de suplementos y de leche Liconsa se obtuvo del cuestionario de Frecuencia de Consumo de Alimentos y morbilidad por autorreporte de la madre. Se emplearon modelos de regresión logística múltiple para el análisis de las asociaciones, ajustados por confusores. Resultados: El consumo medio y alto de leche Liconsa se asoció con menor momio de DH (RM=0.02 [IC95% 0.002,0.24] y RM=0.07 [IC95% 0.01,0.52]) y anemia (RM=0.13 [IC95% 0.04,0.37] y RM=0.17 [IC95% 0.03,0.87]). Un alto consumo de leche Liconsa (RM=0.09, [IC95% 0.01,0.44]) y de Vitaniño (RM=0.05 [IC95% 0.005, 0.46]) se asoció con menor momio de diarrea. Conclusiones: Es necesario considerar la continuidad del consumo de suplementos nutricionales para mejorar la salud y el estado de micronutrimentos en población infantil mexicana vulnerable.


Abstract: Objective: To analyze the association between supplements and Liconsa milk intake, with anemia, zinc (ZD) and iron (ID) deficiencies, and morbidity in Mexican children resident of less than 100 000 habitants' localities. Materials and methods: A subsample of 1 516 children aged 1-4 participants of Ensanut 100k was analyzed, carried out in 2018. Anemia was considered if [Hb]<11 g/dL, ZD if [Zn]<65 µg/dL and ID if [ferritin]<12 µg/L. Supplements and Liconsa milk consumption were obtained from a semi-quantitative food frequency; morbidity by self-report of the mother. Multiple logistic regression models were used adjusted by confounders. Results: Medium and high consumption of Liconsa milk was associated to lower odds of ID (OR=0.02, [95%CI 0.002,0.24] and OR=0.07, [95%CI 0.01,0.52]) and anemia (OR=0.13, [95%CI 0.04,0.37] and OR=0.17, [95%CI 0.03,0.87]). A high intake of Liconsa milk (OR=0.09, [95%CI 0.01,0.44]) and Vitaniño (OR=0.05 [95%CI 0.005, 0.46]) were both associated to lower diarrhea risk. Conclusions: To assure the continuity of the consumption of nutritional supplements is necessary for improving the health and the micronutrients status in vulnerable Mexican children.

ABSTRACT

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.


Objetivou-se neste trabalho avaliar a metabolizabilidade, o desempenho zootécnico e a viabilidade econômica da inclusão de glicerina purificada, em dietas balanceadas para frangos de corte dos 8 aos 21 dias de idade. Foram realizados dois experimentos, sendo que, no primeiro experimento, foram utilizados 100 pintos de 14 dias de idade, distribuídos em delineamento inteiramente casualizado (DIC), com dois tratamentos, cinco repetições de 10 aves. Os tratamentos consistiram de uma dieta referência e uma dieta teste, na qual a glicerina purificada substituiu 10% da dieta referência. No segundo experimento, foram utilizados 200 pintos de 8 dias de idade, distribuídos em delineamento experimental inteiramente casualizado (DIC), com quatro tratamentos (0, 2, 4 e 6% de inclusão de glicerina purificada) e cinco repetições de 10 aves. Foram determinados o ganho de peso, consumo de ração, conversão alimentar, peso final, energia metabolizável aparente (EMA), energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMAn), os coeficientes de metabolizabilidade da matéria seca (CMMS), proteína bruta (CMPB), energia bruta (CMEB) e o custo da alimentação por kg de frango produzido. A EMA, EMAn e os CMMS, CMPB, CMEB da glicerina purificada obtida foram de 3790, 3560 Kcal/kg e 83,72, 71,52, 86,27%, respectivamente. Observou-se que a inclusão de glicerina purificada não afetou (p>0,05) o desempenho (ganho de peso, consumo de ração, conversão alimentar e peso final). O menor custo com a alimentação e a maior margem bruta foi obtido com os frangos alimentados com 6% de inclusão de glicerina purificada. A inclusão de 6% de glicerina purificada em dietas balanceadas para frangos de corte dos 8 aos 21 dias de idade, mostrou-se técnica e economicamente viável.

ABSTRACT

Beauregard biofortified sweet potato is a tuberous root with a high content of carotenoids whose consumption can bring beneficial effects on human health related to the biological actions of these substances. The objectives of this study were to evaluate the acceptance of cake made with sweet potato biofortified with carotenoids by school children enrolled in a school of the municipal education network of the city of Teresina PI. The sweet cake containing biofortified potato (Beauregard) (PC) was compared with standard sweet wheat flour (WC) cake formulation. The PC and WC products and the Beauregard potato were analyzed for centesimal composition (moisture, ashes, proteins, lipids and carbohydrates) and total carotenoid content. Acceptance of PC was assessed by means of an acceptance test with a hedonic scale of five points applied to 100 children from 08 to 10 years of age. The evaluation of the centesimal composition showed protein content corresponding to 2.1% in WC and 3.57% in PC, and of lipids of 5.16% in WC and 8.95% inPC. Regarding the moisture content, WC presented 32.5% and PC 38.44%. The content of fixed minerals (ash) found in formulations was 1.9% and 1.26%, respectively, in WC and PC. The carotenoid content (µg of ß-carotene.g-1) was significantly higher (p <0.05) in the biofortified potato (3,200.01 ± 0.02) and in the PC formulations (3,666.17 ± 2.55) and WC (3,066.53 ± 1.88) for common sweet potatoes (2.200,23 ± 1.63). In the five-point facial hedonistic acceptance test, the formulation containing biofortified potato (PC) obtained a significantly higher score (p <0.05) (4.24 ± 0.93) when compared to the WC formulation (3.75 ± 1.19). The biofortified potato and the cake containing the biofortified potato presented some characteristics related to the centesimal composition similar to those found in WC and the content of carotenoids in PC larger than those of WC. Because sweet cake is a food product, generally well accepted by children and adults, PC's greateracceptance of WC suggests its promising potential for consumption by the population.


A batata-doce Beauregard biofortificada é uma raiz tuberosa com alto teor de carotenoides, cujo consumo pode trazer efeitos benéficos na saúde humana relacionados com as ações biológicas dessassubstâncias. Os objetivos deste estudo foram avaliar a aceitação de bolo elaborado com batata doce biofortificada com carotenoides por crianças em idade escolar matriculados em uma escola da rede municipal de ensino da cidade de Teresina PI. O bolo doce contendo batata biofortificada (Beauregard) (BB) foi comparado com formulação padrão de bolo doce de farinha de trigo (BT). Os produtos BB e BT e a batata Beauregard foram analisados quanto à composição centesimal (umidade, cinzas, proteínas, lipídeos e carboidratos) e conteúdo de carotenóides totais. A aceitação do BB foi avaliada por meio de teste de aceitação com escala hedônica facial de cinco pontos aplicado em 100 crianças de 08 a 10 anos de idade. A avaliação da composição centesimal mostrou conteúdo protéico correspondendo 2,1% no BT e 3,57% no BB, e de lipídiosde 5,16% no BT e 8,95% no BB. Em relação ao teor de umidade, o BT apresentou 32,5% e BB 38,44%. O teor de minerais fixos (cinzas) encontrado nas formulações foi de 1,9% e 1,26%, respectivamente, no BT e BB. O conteúdo de carotenoides (µ g de ß-caroteno.g-1) foi significativamente maior (p<0,05) na batata biofortificada (3.200,01 ± 0,02) e nas formulações BB (3.666,17 ± 2,55) e BT (3.066,53 ± 1,88) em relação à Figure 1. Acceptance rate of Beauregard potato and wheat cake formulations.. batata doce comum (2.200,00 ± 1,63). No teste de aceitação escala hedonica facial de cinco pontos a formulação contendo batata biofortificada (BB) obteve nota significativamente maior (p<0,05) (4,24± 0,93) quando comparada com a formulação BT (3,75± 1,19). A batata biofortificada e o bolo contendo a batata biofortificada apresentaram algumas características relacionadas à composição centesimal semelhantes àquelas encontradas no BT e conteúdo de carotenoides no BB maiores que os do BT. Por ser o bolo doce um produto alimentício, de modo geral, bem aceito por crianças e adultos, a maior aceitação do BB em relação ao BT sugere seu potencial promissor para consumo pela população.

ABSTRACT

ABSTRACT The aim of this work was to improve sweet bread (R1) nutritionally by partially replacing the wheat flour with other non-traditional flours through linear programming. Chemical Score, lipid profile, microbiological quality and acceptability were determined. Both recipes, R2 and R3, were formulated according to the Dietary Guidelines for Americans; and R3 according to the maximum amounts of flours that impart negative sensory attributes, as well. The resulting proportions were: wheat/broad bean/chia/ amaranth flours 64/22/13/0 (R2) and 83/2/4/11 (R3). The obtained products presented adequate contributions of proteins and lipids, while fiber increased significantly. The Chemical Score increased from 46% (R1) to 95% (R2) and to 91% (R3) respectively, and the fatty acids ratio ω3: ω6 improved. R2 was not sensorially accepted while R3 presented high acceptability in adults and school-aged children. Recipe R3 could be included in school menus to improve children's nutritional status.


RESUMEN El objetivo de este trabajo fue mejorar nutricionalmente un pan dulce (R1), reemplazando parcialmente la harina de trigo con otras harinas no tradicionales a través de la programación lineal. Se determinó la puntuación química, el perfil lipídico, la calidad microbiológica y la aceptabilidad. Ambas recetas enriquecidas nutricionalmente, R2 y R3, se formularon de acuerdo a pautas dietéticas estadounidenses; y para R3, además, se tuvieron en cuenta las cantidades máximas de harinas que imparten atributos sensoriales negativos. Las proporciones resultantes fueron harina de trigo/haba/chía/amaranto 64/22/13/0 (R2) y 83/2/4/11 (R3). Los productos obtenidos presentaron contenidos adecuados de proteínas y lípidos, mientras que la fibra aumentó significativamente. La puntuación química aumentó de 46% (R1) a 95% (R2) y a 91% (R3) respectivamente, y la relación de ácidos grasos ω3: ω6 mejoró. R2 no fue aceptado sensorialmente, mientras que R3 presentó alta aceptabilidad en adultos y niños en edad escolar. La receta R3 podría incluirse en los menús escolares para mejorar el estado nutricional de los niños.

ABSTRACT

as been proposed that the consumption of common beans (Phaseolus vulgaris L.) reduces cardiovascular risk, and prevents and controls both chronic and degenerative diseases. The aim of this study was to compare the antioxidant capacity of a bean-fiber fortified bar (BFB) versus a commercial bar (CB) in 60 Mexican men and women (18-65 years old), who were randomly distributed in two groups: BFB or CB; individuals consumed a bar a day for one month. Anthropometric data, food intake and blood samples were collected. Glucose tolerance (GTT), lipid profile (PL), and lipid peroxidation (TBARS) tests were performed; carbonyls groups in serum oxidized proteins were also measured. GTT and PL were not different between both groups in either the 15 or 30-day follow-up of bar consumption assessments. There were no significant differences in either TBARS or carbonyl concentration between groups; BFB group showed higher levels of serum lipid peroxidation in basal and fifteen days measurements; these levels decreased at the final evaluation: No differences were detected on carbonyl levels between groups. In conclusion, 30 days of fiber bean bar consumption did not alter glucose or PL levels, while, in the BFF group, oxidative stress decreased within 30 days of the consumption of the fortified bar(AU)


Se ha propuesto que el consumo de frijol común (Phaseolus vulgaris L.) reduce el riesgo cardiovascular, y previene y controla las enfermedades crónicas y degenerativas. El objetivo del presente estudio fue comparar la capacidad antioxidante de una barra fortificada con fibra de frijol (BFB) versus una barra comercial (CB) en 60 hombres y mujeres mexicanos (18-65 años de edad), quienes aleatoriamente fueron distribuidos en dos grupos: El grupo BFB y el CB que consumieron la barras fortificada con frijol y la barra comercial, respectivamente, durante un mes. Se recopilaron datos antropométricos, ingesta de alimentos y muestras de sangre. Se realizó prueba de tolerancia a la glucosa (GTT), el perfil de lípidos (PL), la peroxidación de lípidos (TBARS) y la cuantificación de carbonilos en proteínas oxidadas como pruebas de bioquímica sanguínea. GTT y PL no fueron diferentes entre ambos grupos en la evaluación de seguimiento de 15 y 30 días del consumo de la barra. No hubo diferencias significativas en los TBARS o la concentración de carbonilo entre los grupos, el grupo BFB mostró niveles más altos de peroxidación de lípidos en suero en la fase basal y a los quince días del consumo de la barra; curiosamente, estos niveles disminuyeron en la evaluación final. No se detectaron diferencias en los niveles de carbonilo entre los grupos. En conclusión, 30 días de consumo de barras de fibra de frijol no alteraron los niveles de glucosa o PL; mientras que, en el grupo BFB, el estrés oxidativo disminuyó a los 30 días del consumo de la barra fortificada(AU)
