Abstract Butia capitata, native to the Brazilian cerrado, is underutilized for human consumption. The objective was to determine the physical characteristics of the fruit, centesimal composition, bioactive and antioxidant activity. Fruits obtained in Montes Claros, Minas Gerais, Brazil. Diameter, height and weight were evaluated. The moisture was analyzed by gravimetry after oven drying, ashes by calcining in a muffle furnace, proteins by the Kjeldahl method, gravimetric lipids after extraction in ethyl ether, carbohydrates by difference and total energy value by conversion factors. Vitamin C, E and carotenoids were analyzed by HPLC, minerals by inductively coupled plasma atomic absorption spectrometry, Folin Ciocalteu solution phenolic compounds, anthocyanins by spectrophotometry and antioxidant capacity by the Radical DPPH. The fruits presented good pulp yield (68.59%), which has a high lipid content (3.42 g.100 g-1) and total energy (83.34 kcal.100 g-1). The pulp contains ß-carotene (8.56 mg.100 g-1), vitamin E (121.07 mcg.100 g-1) and high concentrations of vitamin C (53.57 mg.100 g-1), total phenolics (493, 6 mg.100 g-1) and copper (1.80 mg.100 g-1). Almond has a high value of total energy (457.72 kcal.100 g-1), vitamin E (1594.39 mcg.100 g-1) and minerals Cu (2.40 mg.100 g-1) and Mo (0.9.100 g-1). The pulp is a source of carotenoids, vitamin C, copper and total phenolics, both natural antioxidants.

Abstract Introduction: sedentary behavior (SB) has been independently associated with detrimental health outcomes in different regions worldwide. The aim of this systematic review was to examine whether domain-specific SB is associated with cardiometabolic diseases (CMD) and related biomarkers in South American adults. Methods: nine electronic databases were searched to identify all studies that analyzed the association between SB and CMD –e.g. obesity, diabetes, hypertension, metabolic syndrome (MetS) and clustering of chronic diseases (CCD) – and related biomarkers in South American adults. Two independent reviewers performed the necessary Abstract/full-text screening, data abstraction, and quality assessments. The review protocol was registered in the PROSPERO database (CRD42018099319). Results: from the 1,262 articles identified in the search 262 were reviewed in full and 20 were used in the analysis in accordance to the inclusion criteria. High SB (mainly sitting and TV time) was associated with an increased likelihood of obesity (n = 8), diabetes (n = 6), and CCD (n = 3), as well as high values of BMI (n = 8), WC (n = 7), % BF (n = 4), plasma lipids (n = 4), and glycemia (n = 5). Eleven out of 20 studies were of higher quality. Conclusion: long time spent in SB, mainly sitting and TV time, was positively associated with the occurrence of CMD and related biomarkers in South American adults.

Resumen Introducción: el comportamiento sedentario (CS) se ha asociado de forma independiente con resultados perjudiciales para la salud en diferentes regiones del mundo. El objetivo de esta revisión sistemática fue examinar si el CS específico de cada dominio se asocia o no a enfermedades cardiometabólicas (ECM) y sus biomarcadores relacionados en adultos sudamericanos. Métodos: se realizaron búsquedas en nueve bases de datos electrónicas para identificar todos los estudios que habían analizado la asociación entre CS y ECM –por ejemplo, obesidad, diabetes, hipertensión, síndrome metabólico y agrupación de enfermedades crónicas (AEC)– y sus biomarcadores relacionados en adultos sudamericanos. Dos revisores independientes realizaron evaluaciones de los resúmenes/textos completos, el resumen de los datos y evaluaciones de calidad. El protocolo de revisión está registrado en la base de datos PROSPERO (CRD42018099319). Resultados: de los 1262 artículos identificados en la búsqueda, 262 se revisaron en su totalidad y 20 se utilizaron en el análisis de acuerdo con los criterios de inclusión. El gran CS (principalmente, tiempo sentado y de televisión) se asoció a una mayor probabilidad de obesidad (n = 8), diabetes (n = 6) y AEC (n = 3), así como a valores altos de IMC (n = 8), WC (n = 7), % BF (n = 4), lípidos plasmáticos (n = 4) y glucemia (n = 5). Once de los 20 estudios fueron de alta calidad. Conclusión: la gran cantidad de tiempo invertido en el CS, principalmente el tiempo sentado y de televisión, se asoció positivamente con la aparición de ECM y sus biomarcadores relacionados en adultos de América del Sur.

Resumo Este artigo descreve a relação de mães enlutadas com a alimentação, com base na fenomenologia existencial, considerando que o espaço familiar alimentar, protagonizado pela matriarca, pode ser perturbado com a perda de um filho. Foram realizadas entrevistas com quinze mães frequentadoras de Organizações Não Governamentais de apoio ao luto, com idade entre 40 e 61 anos. Da análise emergiram quatro eixos temáticos que indicam como a mãe enlutada se comporta no contexto da alimentação: a ausência de fome e do prazer em se alimentar; o ato de compartilhar refeições versus o luto materno; o confronto com a “cadeira vazia”; reações e sentimentos diante da culinária que simboliza a memória do filho. A influência que o luto exerce na relação das mães com a alimentação foi evidenciada de diversas maneiras, seja na ausência de fome, na alteração do peso e na falta do(a) filho(a) nas interações sociais durante as refeições compartilhadas, representando os desafios da mãe perante uma “mesa que encolheu”, exigindo das mesmas novas significações frente à alimentação. Compreende-se que a relação da enlutada com a alimentação é permeada de conflitos que a expõe a risco de desvios nutricionais e demanda apoio com profissionais sensíveis e esclarecidos sobre essa condição.

Abstract This article describes the relationship of bereaved mothers with eating habits, based on the existential phenomenology considering that the family food space, led by the matriarch, can be disturbed due to the loss of a child. Interviews were conducted with fifteen women attending non-governmental bereavement support groups, aged between 40 and 61 years of age. Based on the analysis of the interviews, four thematic categories emerged revealing how grieving mothers behave: loss of appetite and pleasure in eating food; the action of sharing meals versus maternal mourning; the confrontation with the “empty chair”; and reactions due to the culinary act that symbolizes the memory of the child. The influence of grief on the relationship between mothers and food was verified in several ways, either in the loss of appetite, the body weight change or in the absence of the child in the social interactions during shared meals, which represent the challenges of the mother facing the “table that shrank,” calling for the mothers to find new meanings for eating. It is understood that the relationship of the bereaved mother with food is surrounded by conflicts that expose the mother to nutritional risks and demands support from professionals who are both sensitive and well informed about this condition.

RESUMO O objetivo deste trabalho é construir uma tabela de conteúdo de iodo de alimentos visto que tais informações são necessárias para que políticas públicas possam estabelecer metas nutricionais e no Brasil não existem dados do conteúdo de iodo dos alimentos, dificultando a avaliação do consumo pela população. Na construção da tabela utilizou-se bancos de dados de 14 países. Os alimentos utilizados foram aqueles listados na Pesquisa de Orçamentos Familiares de 2008-2009, exceto aqueles que continham sal de adição e os que suscitaram dúvidas em relação à existência de submissão ou não a algum preparo. A compilação dos bancos de dados internacionais do conteúdo de iodo resultou em 266 alimentos, os quais foram reunidos em 15 grupos. Foi realizada também a quantificação de iodo por grupo de alimentos e no sal iodado. Os dados foram apresentados como mediana, mínimo e máximo. Foi encontrada grande variação no conteúdo de iodo dos alimentos entre os países e inter e intra grupos de alimentos. Os que apresentaram maiores conteúdos foram o dos pescados e frutos do mar e dos laticínios. Em relação à iodação do sal, os países seguiram a recomendação da Organização Mundial da Saúde, exceto, Espanha, Noruega e Turquia. A tabela do conteúdo de iodo de alimentos poderá ser um instrumento útil para avaliação da ingestão de iodo, sendo importante em pesquisa do estado nutricional, orientação alimentar e programas de saúde pública.

ABSATRCT In Brazil, there are no data on the iodine content of foods, making it difficult for the population to assess their consumption of iodine. Such information is necessary for public policies aimed at establishing nutritional goals. The objective this article is to construct a table of the iodine content of foods. For the construction of the table, databases from 14 countries were used. The foods used were those listed in the 2008-2009 Household Budget Survey, except those containing added salt, and the doubts about whether or not the food was submitted to any kind of preparation. The compilation of international databases of iodine content resulted in 266 foods, which were grouped into 15 groups. Iodine was also quantified by food group and iodized salt. Data were presented as median, minimum, and maximum. A broad variation in the iodine content of foods was found between countries and inter- and intra-food groups. Those with the highest content were fish and seafood, and dairy products. Regarding salt iodization, these countries followed the recommendation of the World Health Organization, except for Spain, Norway and Turkey. The Food Iodine Content Table can be a useful tool for assessing iodine intake, being important in research on nutritional status, food guidance, and public health programs.

ABSTRACT Our aim was to associate anthropometric profile, body composition and body image perception with a positive screening for eating disorders in adolescents aged 10 to 14 years. The screening for eating disorders was carried out using the Eating Attitudes Test (EAT-26), Children's Eating Attitudes Test (ChEAT) and Bulimic Investigatory Test Edinburgh (BITE). Weight, height and percentage of body fat were measured, the latter by a vertical bipolar bioimpedance. Body image perception was assessed using the Brazilian Silhouette Scale. The project was approved by the Ethics Committee for Human Research of the Federal University of Viçosa, Minas Gerais, Brazil. 1,300 adolescents were evaluated. The prevalence of screening for eating disorders was 5.5% (n= 71), overweight was 26.1% (n= 339) and high body fat percentage was 38.5% (n= 500). Body distortion was present in 56.9% (n= 740) of adolescents and body dissatisfaction was 79.3% (n= 1,031). Body Mass Index, the percentage of body fat and body dissatisfaction were considered risk factors for positive screening for eating disorders. It is important to evaluate the physical changes in adolescence and their implications on body dissatisfaction, the main risk factor for the development of eating disorders.

RESUMEN El objetivo de ese estudio fue asociar el perfil antropométrico, la composición corporal y la percepción de la imagen corporal con un screening positivo de los trastornos alimentarios en adolescentes de 10 a 14 años. Se realizó la aplicación del Eating Attitudes Test (EAT-26), Children's Eating Attitudes Test (ChEAT) y Bulimic Investigatory Test Edinburg (BITE) para evaluar la detección de trastornos alimentarios. Se midió el peso, la talla, porcentaje de grasa corporal y la percepción de la imagen corporal. El proyecto fue aprobado por el Comité de Ética para la Investigación Humana de la Universidad Federal de Viçosa, Minas Gerais, Brasil. Se evaluó a 1.300 adolescentes y la prevalencia de detección de trastornos alimentarios fue del 5,5% (n= 71). La prevalencia de sobrepeso fue de 26,1% (n= 339) y porcentaje de grasa corporal alto fue 38,5% (n= 500). La distorsión corporal estuvo presente en el 56,9% (n= 740) de los adolescentes, y la insatisfacción corporal fue de 79,3% (n= 1,031). El Índice de Masa Corporal real, el porcentaje de grasa corporal y la insatisfacción corporal fueron considerados factores de riesgo para la detección positiva de trastornos alimentarios. Es importante evaluar los cambios físicos en la adolescencia y sus implicaciones en la insatisfacción corporal, factor de riesgo para el desarrollo de trastornos alimentarios.

RESUMO O acúmulo de gordura corporal é um dos principais fatores de risco de doenças cardiometabólicas. A obesidade pode ser considerada uma doença inflamatória sistêmica crônica em adultos e em pessoas mais jovens. O controle do processo de inflamação subclínica por meio da prática de atividade física (AF) pode atenuar os efeitos dos fatores de risco que desencadeiam a aterosclerose que se agrava com a idade. O objetivo deste estudo foi realizar uma revisão sistemática sobre a influência da atividade física e/ou do exercício sobre marcadores cardiometabólicos e outros fatores de risco de doenças cardiovasculares em adolescentes. A revisão sistemática foi realizada nas bases de dados eletrônicas Scopus, Pubmed, Conchrane Collection e SciELO. Os termos usados para a busca foram "cardiovascular diseases AND inflammation AND adolescents AND physical activity OR exercise". Foram avaliados 24 artigos originais, 14 estudos longitudinais e 10 transversais. No geral, 16 artigos (66,66%) mostraram que a AF, o exercício físico e/ou comportamento sedentário influenciaram ou se relacionaram com a concentração de marcadores cardiometabólicos. Todos os estudos que analisaram mudanças do estilo de vida mostraram redução dos marcadores cardiometabólicos. Algumas limitações foram observadas: amostras pequenas, falta de prescrição dietética, controle e avaliação de volume e intensidade do exercício físico. A maioria dos estudos analisados mostrou que a atividade física pode influenciar e diminuir as concentrações dos marcadores cardiometabólicos em adolescentes. No entanto, estudos com tamanho amostral representativo e com controle da avaliação do nível de atividade e/ou exercício físico são necessários para verificar com acurácia as alterações que o estilo de vida mais ativo pode apresentar no processo de inflamação, assim como em outros fatores de risco de doenças cardiometabólicas em adolescentes.

ABSTRACT The accumulation of body fat is a major risk factor for cardiometabolic diseases. Obesity can be considered a chronic systemic inflammatory disease in adults and younger people. The control of subclinical inflammation process through the practice of physical activity (PA) can mitigate the effects of risk factors that trigger atherosclerosis that worsens with advancing age. The objective of this study was to conduct a systematic review of the influence of physical activity and/or exercise on cardiometabolic markers and othrer risk factors of cardiovascular disease in adolescents. A systematic review was conducted in electronic databases Scopus, Pubmed, Conchrane Collection and SciELO. The terms used in the search were "cardiovascular diseases AND inflammation AND adolescents AND physical activity OR exercise". A total of 24 original articles were evaluated, being 14 longitudinal and 10 cross-sectional studies. Overall, 16 articles (66.66%) showed that PA, exercise and/or sedentary behavior may have influenced or have been related to the concentration of cardiometabolic markers. All studies that examined lifestyle changes showed reduction of cardiometabolic markers. Some limitations were observed: reduced samples, lack of dietary prescription, evaluation and control of volume and intensity of exercise. Most of the studies analyzed showed that the physical activity could influence and decrease the concentrations of cardiometabolic markers in adolescents. However, studies with representative sample size and precise control in assessing the level of physical activity and/or exercise are required to determine accurately the changes that the more active lifestyle can bring on inflammatory process, as well as other risk factors for cardiometabolic diseases in adolescents.

En general, 16 artículos (66,66%) mostraron que la AF, el ejercicio y/o el comportamiento sedentario han influenciado o se relacionado con la concentración de los marcadores cardiometabólicos. Todos los estudios que examinaron el cambio de estilo de vida mostraron una reducción de los marcadores cardiometabólicos. Se observaron algunas limitaciones: muestras pequeñas; falta de prescripción dietética; control y evaluación del volumen y de la intensidad del ejercicio. La mayoría de los estudios analizados demostraran que la actividad física puede influenciar y disminuir las concentraciones de marcadores cardiometabólicos en los adolescentes. Sin embargo, se requieren estudios con tamaño representativo demuestra y que avalúen el control del nivel de actividad física y/o ejercicio para determinar con precisión los cambios que el estilo de vida más activo puede presentar en el proceso de inflamación, así como otros factores de riesgo de enfermedades cardiometabólicas en adolescentes.

Resumo Esta revisão teve como objetivo apresentar e discutir os achados mais recentes do efeito dos ácidos graxos monoinsaturados (AGMI) sobre marcadores plasmáticos do metabolismo lipídico em estudos pós-prandiais e de intervenção clínica nutricional. Realizou-se busca em diferentes bases de dados entre 2010 e 2014, usando os seguintes termos de indexação: MUFA, Lipemia, Lipid Metabolism, Triglycerides e Postprandial. O consumo de refeição com alto conteúdo de AGMI tem demonstrado efeito benéfico na resposta lipidêmica pós-prandial, mas se essa resposta pode ser alterada em indivíduos com excesso de peso e/ou outras doenças crônicas após consumo de AGMI, ainda não está totalmente elucidado. De modo geral, após a intervenção com AGMI, os fatores de risco cardiovascular diminuíram, além de haver melhora no perfil lipídico. Em conclusão, os estudos recentes têm demonstrado um efeito benéfico do consumo de AGMI em curto e longo prazos, mediante aumento/manutenção das concentrações de HDL colesterol e diminuição do LDL colesterol.

Abstract The objective of this review is to present and discuss the most recent findings related to the effects of monounsaturated fatty acids (MUFA) on plasma markers of lipid metabolism observed in postprandial studies and clinical nutritional intervention studies. Searches were conducted on several different databases for publications from 2010 to 2014 using the following keywords: MUFA, Lipemia, Lipid Metabolism, Triglycerides and Postprandial. High-MUFA meal has presented beneficial effect on postprandial lipidemia response, but it is not yet completely clear whether this response to MUFA intake may be different in people with excess weight and/or other chronic diseases. In general, cardiovascular risk factors were reduced and lipid profiles improved after interventions with MUFA. In conclusion, recent studies have demonstrated that consuming MUFA has beneficial effects at short and long time by increasing/maintaining HDL-cholesterol concentrations and reducing levels of LDL cholesterol.

ABSTRACTThe aim of this study was to investigate the effect of the bark extractBathysa cuspidata on chemically induced preneoplastic colorectal lesions in Wistar rats. Forty male rats were randomly divided into four groups (n = 10 each): saline (control group, oral administration of saline solution 0.9%); dimethylsulfoxide (DMSO, vehicle control), B200 (treated with 200 mg/kg bark extract ofB. cuspidata), and B400 (treated with 400 mg/kg bark extract ofB. cuspidata). Administration of treatments was carried out by the gavage. The animals received four subcutaneous injections of 1,2-dimethylhydrazine (DMH, 40 mg/kg) in the initial two weeks of the experiment to induce preneoplastic colorectal lesions. After 15 weeks, the animals were euthanized and the presence of aberrant crypt foci (ACF), body weight, biochemical analyses, and oxidative stress markers were measured. The extract ofB. cuspidata decreased the levels of superoxide dismutase (SOD), but did not influence the levels of catalase (CAT), malondialdehyde (MDA), nitric oxide or protein carbonyl, compared with the saline group. The animals supplemented with a more concentratedB. cuspidata extract (B400) showed a significant reduction in the number of ACF in all the portions of the intestinal mucosa. The study demonstrated that the bark extract ofB. cuspidata at 400 mg/kg reduced the preneoplastic colorectal lesions in an animal model of colon cancer and that the effect could be dose-dependent.

OBJETIVO: Determinar a ocorrência de síndrome metabólica (SM) e do fenótipo cintura hipertrigliceridêmica (CH) em amostra de adolescentes e estabelecer qual indicador antropométrico melhor identifica SM e CH, de acordo com gênero e fase da adolescência. MÉTODOS: Estudo transversal com 800 adolescentes (414 meninas) de 10-19 anos. Indicadores antropométricos (índice de massa corporal, perímetro da cintura, relação cintura/estatura, relação cintura/quadril e relação pregas cutâneas centrais/periféricas) foram determinados por protocolos padronizados. Para diagnóstico da SM, foi usada a proposta de Ferranti et al. (2004). A CH foi definida pela presença simultânea de perímetro da cintura aumentado (>75 percentil por idade e sexo) e triglicerídeos elevados (>100 mg/dL). O desempenho dos indicadores antropométricos foi avaliado por meio da curva Receiver Operating Characteristic. RESULTADOS: A prevalência de SM foi idêntica à de CH (6,4%), sem diferenças entre os gêneros e entre as fases da adolescência. O perímetro da cintura apresentou maior área abaixo da curva no diagnóstico da SM, exceto para meninos entre 17-19 anos, para os quais a relação cintura/estatura exibiu melhor desempenho. No diagnóstico da CH, a cintura isolada apresentou maior área abaixo da curva, exceto para os meninos nas fases inicial e final da adolescência, nos quais a relação cintura/estatura obteve maior área. A relação entre as pregas cutâneas apresentou pior desempenho para identificar SM e CH. CONCLUSÕES: O perímetro da cintura e a relação cintura/estatura mostraram o melhor desempenho para identificar SM e CH em ambos os sexos e nas três fases da adolescência.

OBJECTIVE: To determine the prevalence of metabolic syndrome (MS) and the hypertriglyceridemic waist phenotype (HW) in a representative adolescent sample; as well as to establish which anthropometric indicator better identifies MS and HW, according to gender and adolescent age. METHODS: This cross sectional study had the participation of 800 adolescents (414 girls) from 10-19 years old. Anthropometric indicators (body mass index, waist perimeter, waist/stature ratio, waist/hip ratio, and central/peripheral skinfolds) were determined by standard protocols. For diagnosis of MS, the criteria proposed by de Ferranti et al. (2004) were used. HW was defined by the simultaneous presence of increased waist perimeter (>75th percentile for age and sex) and high triglycerides (>100 mg/dL). The ability of anthropometric indicators was evaluated by Receiver Operating Characteristic curve. RESULTS: The prevalence of MS was identical to HW (6.4%), without differences between genders and the adolescence phases. The waist perimeter showed higher area under the curve for the diagnosis of MS, except for boys with 17-19 years old, for whom the waist/stature ratio exhibited better performance. For diagnosing HW, waist perimeter also showed higher area under the curve, except for boys in initial and final phases, in which the waist/stature ratio obtained larger area under the curve. The central/peripheral skinfolds had the lowest area under the curve for the presence of both MS and HW phenotype. CONCLUSIONS: The waist perimeter and the waist/stature showed a better performance to identify MS and HW in both genders and in all three phases of adolescence.

Introduction: The evaluation of inflammatory markers during adolescence can monitor different stages and manifestation of chronic diseases in adulthood. The control of the subclinical inflammation process through changes in lifestyle, especially in the practice of physical activity and dietary education can mitigate the effects of risk factors that trigger the process of atherosclerosis. Objective: To do a critical review regarding inflammatory markers as a risk factor of cardiovascular disease in relation to body composition, physical activity and assessment of nutritional status of adolescents. Methods: A literature review was performed in the following electronic databases: PUBMED, SCIELO and CONCHRANE COLLECTION. The following associated terms were used "inflammation AND cardiovascular diseases AND nutritional status OR body composition OR physical activity". There were topics created for the discussion of subjects: obesity and risk factors for cardiovascular disease during adolescence; expression of inflammatory markers in adolescence; development of cardiovascular disease with inflammatory markers, and finally, inflammatory markers, physical activity and nutritional evaluation. Results: It was observed that the inflammatory markers may manifest in adolescence and be related to risk factors for cardiovascular diseases. Physical activity and nutritional evaluation featured as non-pharmacological measures to control the incidence of inflammatory markers and cardiovascular risk factor.Conclusions: Intervention studies may clarify how the adoption of a more proper lifestyle can influence the inflammatory process.

Introducción: La evaluación de los marcadores inflamatorios en la adolescencia puede monitorear diferentes etapas y manifestación de las enfermedades crónicas en la edad adulta. El control del proceso de inflamación subclínica mediante cambios en el estilo de vida, especialmente en la práctica de la actividad física y la educación dietética puede mitigar los efectos de los factores de riesgo que desencadenan el proceso de la aterosclerosis. Objetivo: Hacer una revisión crítica sobre los marcadores inflamatorios como un factor de riesgo de enfermedad cardiovascular (ECV) en relación con la composición corporal, la actividad física y la evaluación del estado nutricional de los adolescentes. Métodos: Una revisión de la literatura se realizó en las siguientes bases de datos electrónicas: PUBMED, SCIELO y COLECCIÓN CONCHRANE. Los siguientes términos asociados se utilizaron "composición de la inflamación y las enfermedades cardiovasculares y el estado nutricional, organismo o la actividad física". Había temas creados para la discusión de la materia: factores de obesidad y riesgo de enfermedad cardiovascular en la adolescencia; expresión de marcadores inflamatorios en la adolescencia; desarrollo de la enfermedad cardiovascular con marcadores inflamatorios y, por último, los marcadores de inflamación, la actividad física y la evaluación nutricional. Resultados: Se observó que los marcadores inflamatorios pueden manifestarse en la adolescencia y se relaciona con factores de riesgo de enfermedades cardiovasculares. La actividad física y la evaluación nutricional ofrecida como medidas no farmacológicas para el control de la incidencia de los marcadores inflamatorios y factores de riesgo cardiovascular. Conclusiones: Los estudios de intervención pueden aclarar cómo la adopción de un estilo de vida más adecuada puede influir en el proceso inflamatorio.

Objective: The goal of this study was to investigate the preventive effects of defatted flaxseed meal on the appearance of aberrant crypt foci (ACF) in mice treated with 1,2-dimethylhydrazine (DMH). Materials and Methods: ACF were induced by intraperitoneal administration of 20 mg/kg body weight of DMH for 8 weeks. The animals were divided into three treatments (n=8): AIN93M diet without fibers + DMH (C-); AIN93M diet with defatted flaxseed meal (LIN); and AIN93M diet with defatted flaxseed meal + DMH (LINCA), for 15 weeks. The technique RT-PCR was used to evaluate the expression of p16, p21, p53, cyclin D1, and cyclin E in the distal colon. In addition, flow cytometric analysis of CD4 and CD8 spleen cells, the quantification of short-chain fatty acids (SCFA) in stool, the quantification of Bifidobacterium spp., Clostridium spp. in feces. Results: LIN and LINCA showed increased Bifidobacterium spp. compared with control (C-). In relation to the weight of the organs, the groups LIN and LINCA showed higher values for the liver and kidney compared with control (C-). Regarding ACF, the group LINCA presented fewer ACF in the middle and distal colon compared with control (C-). When we analyzed ACF with more than three crypts the group LIN and LINCA did not present ACF in the middle and distal segments. LINCA presented increased p53 gene expression. Conclusion: This finding suggests that defatted flaxseed meal reduces ACF by increasing the expression of p53 and increase Bifidobacterium spp.

Objetivo: El objetivo de este estudio fue investigar el efecto preventivo de la harina de linaza desgrasada en el desarrollo de focos de criptas aberrantes (FCA) en ratones tratados con 1,2-dimethylhydrazina (DMH). Material y Métodos: FCA se indujo por inyección intraperitoneal de 20 mg / kg de DMH por kilogramo de peso corporal durante 8 semanas. Los animales fueron divididos en 3 grupos (n = 8): dieta sin fibra de la dieta AIN93M DMH + (C); Dieta AIN93M con harina de linaza desgrasada (LIN); dieta AIN93M y la dieta con harina de linaza desgrasada + DMH (Enlace) durante 15 semanas. RT-PCR se utilizó para evaluar la expresión de p16, p21, p53, ciclina D1, ciclina E y el colon distal. Los análisis CD4 y CD8 se realizaron con citometría de flujo, así como la cuantificación presencia de Bifidobacterium spp. y de Clostridium spp. en las heces. La cuantificación de ácidos grasos de cadena corta (AGCC) fue realizada por lo método de cromatografía de gas. Resultados: LIN y LINCA mostraron un aumento significativo de Bifidobacterium spp., en comparación con el control (C) (p <0,05). Con relación al peso de los órganos, los grupos LIN y LINCA mostraron valores aumentados de hígado y riñón en comparación con el control (C) (p<0,05). Encuanto a la FCA, los grupos FCA LINCA mostró menor en los dos puntos media y distal en comparación con el control (C) (p <0,05). Cuando analizamos FCA con más de tres focos de criptas aberrantes, los grupos LIN y LINCA no presentaron FCA en los segmentos medial y distal, en contraste con el grupo control (p <0,05). LINCA mostró aumento de la expresión del gen p53 (p <0,05). Conclusión: Estos resultados sugieren que la harina de linaza desgrasada reduce FCA, para aumentar la expresión de p53.

OBJETIVO: Verificar a correlação entre medidas de localização da gordura corporal com índice de massa corporal (IMC), percentual de gordura corporal (%GC) e estatura, de acordo com o estado nutricional em adolescentes do sexo feminino. MÉTODOS: Realizou-se estudo transversal controlado, com 113 adolescentes (G1: 38 eutróficas mas com gordura corporal elevada; G2: 40 eutróficas e G3: 35 com excesso de peso), de 14 a 19 anos, de escolas públicas de Viçosa-MG. Aferiu-se peso, estatura, circunferência da cintura (CC), circunferência umbilical (CUm), circunferência do quadril (CQ), circunferência da coxa, relação cintura/quadril (RCQ), relação cintura/estatura (RCE), relação cintura/coxa (RCC), índice de conicidade (IC), diâmetro abdominal sagital (DAS), diâmetro coronal (DC), pregas cutâneas centrais (PCC) e periféricas (PCP). Avaliou-se o %GC por bioimpedância elétrica tetrapolar. RESULTADOS: O aumento da gordura central, representada pela CC, CUm, RCE, DAS, DC e PCC, e o aumento da gordura periférica indicado pela CQ e da coxa foram proporcionais ao aumento do IMC e %GC. A CC e principalmente CUm apresentaram as correlações mais fortes com a adiposidade, enquanto RCQ, RCC, IC e PCC/PCP as mais fracas. A estatura apresentou correlação com praticamente todas as medidas de localização de gordura, sendo de fraca a regular com as medidas da cintura. CONCLUSÕES: Os resultados indicam colinearidade entre massa corporal e adiposidade total com tecido adiposo central e periférico. Recomenda-se o emprego da CUm na avaliação do estado nutricional de adolescentes, pois ela apresentou maior capacidade para predizer adiposidade em cada grupo, além de correlação fraca a regular com a estatura.

OBJECTIVE : To verify the correlation between body fat location measurements with the body mass index (BMI), body fat percentage (BF%) and height, according to the nutritional status in female adolescents. METHODS : A controlled cross-sectional study was carried out with 113 adolescents (G1: 38 with normal weight, but with high body fat level, G2: 40 with normal weight and G3: 35 overweight) from public schools in Viçosa-MG, Brazil. The following measures were assessed: weight, height, waist circumference (WC), umbilical circumference (UC), hip circumference (HC), thigh circumference, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), waist-to-thigh ratio (WTR), conicity index (CI), sagittal abdominal diameter (SAD), coronal diameter (CD), central (CS) and peripheral skinfolds (PS). The BF% was assessed by tetrapolar electric bioimpedance. RESULTS : The increase in central fat, represented by WC, UC, WHtR, SAD, CD and CS, and the increase in peripheral fat indicated by HC and thigh circumference were proportional to the increase in BMI and BF%. WC and especially the UC showed the strongest correlations with adiposity. Weak correlation between WHR, WTR, CI and CS/PS with adiposity were observed. The height showed correlation with almost all the fat location measures, being fair or weak with waist measurements. CONCLUSIONS : The results indicate colinearity between body mass and total adiposity with central and peripheral adipose tissue. We recommend the use of UC for assessing nutritional status of adolescents, as it showed the highest capacity to predict adiposity in each group, and also showed fair or weak correlation with height.

Aims: The consumption of prebiotics has been associated with improvement in the lipid profile. Thus, this review aims to describe the main mechanisms by which inulin-type fructans improve the lipid profile and thereby reduce the cardiovascular risk. Data synthesis: Inulin-type fructans have been demonstrated to improve the lipid profile through a number of mechanisms. These mechanisms include: decrease in gene expression of hepatic enzymes responsible for de novo synthesis of lipids; increase of muscle lipoprotein lipase enzyme activity, enhancing the production of short-chain fatty acids; altered production of polyamines which increases the production of satiogenic peptide; altered blood glucose and insulinemia; increase of fecal excretion of bile salts and cholesterol and increase of the Bifidobacterium population. Conclusions: The consumption of inulin-type fructans enhances lipid profile. Generally, the mechanisms vary according to the physiologic state of the individual and the type of diet to which the inulin-type fructans are added. Thus, inulin may be used for the prevention and/or treatment of cardiovascular diseases.

Objetivos: El consumo de prebióticos ha sido asociado con el mejoramiento del perfil lipídico. Por tanto, esta revisión tiene como objetivo describir los principales mecanismos por los cuales fructanos tipo inulina, mejoran el perfil lipídico reduciendo el riesgo cardivascular. Síntesis de los datos: Los fructanos tipo inulina, han demostrado una mejora del perfil lipídico, a través de varios mecanismos, incluyendo: disminución de la expresión génica de las enzimas hepáticas responsables por la síntesis de novo de lípidos; aumento de la actividad enzimática del lipoproteína lipasa muscular; aumento de la producción de ácidos grasos de cadena corta; producción alterada de poliaminas que aumentan la producción del peptido Satiogen; alteración de la glicemia e insulinemia; aumento de la populación de Bifidobacterium y el incremento de la excreción fecal de las sales biliares y el colesterol. Conclusiones: El consumo de los fructanos tipo inulina mejora el perfil lipídico. Generalmente, los mecanismos varian de acuerdo com el estado fisiológico del individuo y el tipo de dieta, en la que son adicionados los fructanos tipo inulina. Por tanto, la inulina puede ser utilizada para la prevención y/o tratamiento de enfermedades cardiovasculares.
