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.

Introduction: Breast cancer is the second most common cancer in the world, and the most frequent cancer among women. Moreover, there are factors that influence the risk for breast cancer including the age, genetic and endocrine factors, and lifestyle. Objectives: To evaluate the consumption of fatty acids; compare the fatty acids composition in the breast adipose tissue of women with breast cancer and benign breast disease as well as potential risk factors; and describe the genotypic frequency of the Pro12Ala PPARγ polymorphism. Material and methods: A hospital-based case-control study was conducted including incident cases (n = 38 breast cancer; n = 75 benign breast disease; n = 166 control). Lifestyle features, socioeconomic issues, dietary intake, anthropometry, and blood and tissue data were assessed. Results: No differences were observed for fatty acids intake. Interestingly, lauric acid (p = 0.001), myristic acid (p = 0.036), stearic acid (p = 0.031), and total saturated fatty acids (SFAs) (p = 0.048) had lower concentrations in BC than in BBD women, while palmitoleic acid (p = 0.022), erucic acid (p = 0.002), total monounsaturated fatty acids (MUFAs) (p = 0.039) and oleic acid/stearic acid ratio (p = 0.015) increased. There was no significant association between PPARγ polymorphism and studied groups (p = 0.977). The age at first full pregnancy (p = 0.004) was significantly associated with the development BC, whereas BMI (p = 0.005); percentage of body fat (p = 0.024); physical activity (p = 0.036); and age at menarche (p = 0.008), at first full pregnancy (p < 0.001), and of first mammogram (p = 0.018) were significantly associated with the development of BBD. Conclusion: The results suggest a different fatty acids composition of breast adipose tissue, a biomarker of long-term dietary intake, particularly for SFAs, MUFA and 18: 1 n-9/18: 00 ratio. Our findings also show that are differences in the factors related to the development of BC and BBC.

Introducción: el cáncer de mama (CM) es el segundo cáncer más común en el mundo, y el cáncer más frecuente entre las mujeres. Por otra parte, hay factores que influyen en el riesgo de padecer CM, entre los que se encuentran la edad, factores genéticos y endocrinos, y el estilo de vida. Objetivos: evaluar el consumo de ácidos grasos; comparar la composición de ácidos grasos en el tejido adiposo de mama de las mujeres con CM y enfermedad benigna de mama (EBM), así como los posibles factores de riesgo; y describir la frecuencia genotípica del polimorfismo Pro12Ala PPARγ. Material y métodos: se llevó a cabo un estudio caso-control basado en hospitales, incluyendo casos incidentes (n = 38 cáncer de mama, n = 75 enfermedad benigna de mama, n = 166 control). Se evaluaron las características del estilo de vida, las cuestiones socioeconómicas, la ingesta dietética, la antropometría y los datos de sangre y tejidos. Resultados: no se observaron diferencias para la ingesta de ácidos grasos. Curiosamente, ácido láurico (p = 0,001), ácido mirístico (p = 0,036), ácido esteárico (p = 0,031) y los ácidos grasos totales saturados (AGS) (p = 0,048) tenían concentraciones más bajas en CM que en mujeres EBM, mientras ácido palmitoleico (p = 0,022), ácido erúcico (p = 0,002), los ácidos totales grasos monoinsaturados (MUFA) (p = 0,039) y la relación ácido oleico/ácido esteárico (p = 0,015) aumentó. No hubo asociación significativa entre el polimorfismo PPAR gamma y los grupos de estudio (p = 0,977). La edad al primer embarazo (p = 0,004) se asoció de forma significativa con el desarrollo de CM, mientras que el IMC (p = 0,005), porcentaje de grasa corporal (p = 0,024), la actividad física (p = 0,036) y la edad de la menarquia (p = 0,008), al primer embarazo (p < 0,001), y de la primera mamografía (p = 0,018), fueron significativamente asociados con el desarrollo de EBM. Conclusiones: los resultados sugieren una composición diferente de ácidos grasos del tejido adiposo de la mama, un biomarcador de la ingesta dietética a largo plazo, particularmente para SFA, MUFA y 18: 1 n-9/18: 00. Nuestros hallazgos también muestran que existen diferencias en los factores relacionados con el desarrollo de CM y EBM.

Introduction: The prevention strategy of breast cancer is still the key factor for early diagnosis and the most effective method for tracking the disease. Objective: This study aimed to evaluate the association vitamin D level with breast cancer in women. Methods: This hospital case-control study was conducted with 181 women with breast cancer and 197 healthy controls. Vitamin D status, calcium, phosphorus and PTH serum dosage and data collection related to lifestyle and patient's history, besides anthropometric measurements were performed. Univariate analysis (Chi-square and raw odds ratio) and multivariate analysis were performed through multivariate logistic regression. Results: This study shows a higher value of vitamin D in health controls (26.9 mg/dL) than in breast cancer women (24.8 mg/dL). Higher numbers of women with sufficient vitamin D status (34.85%) were found in control group than cancer group. Using the multiple logistic regression model, the family history of breast cancer (OR 36.37, 95%CI 4.75-278.50) and menopause (OR 5.17, 95% CI 2.72-9.80) had a direct association with breast cancer, while the level of vitamin D (OR 0.95, 95%CI 0.91-0.99) and moderate physical activity (OR 0.31, 95%CI 0.10-0.93) maintained the inverse associations with the disease. Conclusion: Vitamin D status and the practice of moderate physical activity were considered protective factors for breast cancer. However, menopause and family history of breast cancer were considered a risk factor for breast cancer.

Introducción: la estrategia de prevención del cáncer de mama sigue siendo el factor clave para el diagnóstico precoz y el método más eficaz para el seguimiento de la enfermedad. Objetivo: este estudio tuvo como objetivo evaluar el nivel de vitamina D asociado con el cáncer de mama en las mujeres. Métodos: este estudio de casos y controles hospitalarios se llevó a cabo con 181 mujeres con cáncer de mama y 197 controles sanas. Se estudió el nivel de vitamina D, calcio, fósforo y la dosis de suero PTH; se recopilaron de datos relacionados con el estilo de vida y com la historia de las pacientes, además se realizaron mediciones antropométricas. El análisis univariante (Chi-cuadrado probabilidades y primas ratio) y el análisis multivariado se realizó mediante regresión logística multivariante. Resultados: este estudio muestra un valor más alto de vitamina D en los controles de salud (26,9 mg/dl) que en las mujeres con cáncer de mama (24,8 mg/dl). Se encontraron más mujeres con suficiente vitamina D (34,85%) en el grupo control que en el grupo de cáncer. Usando el modelo de regresión logística múltiple, la historia familiar de cáncer de mama (OR 36,37; IC del 95%: 4,75 a 278,50) y la menopausia (OR 5,17; IC del 95%: 2,72 a 9,80) se halló una relación directa con el cáncer de mama, mientras que el nivel de vitamina D (OR 0,95; IC del 95%: 0,91 a 0,99) y la actividad física moderada (OR 0,31; IC del 95%: 0,10 a 0,93) mantienen las asociaciones inversas con la enfermedad. Conclusión: el estado de vitamina D y la práctica de actividad física moderada se consideraron factores de protección para el cáncer de mama. Sin embargo, la menopausia y la historia familiar de cáncer de mama se consideran un factor de riesgo para el cáncer de mama.

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.

RESUMEN La acumulación de grasa corporal es uno de los principales factores de riesgo de enfermedades cardiometabólicas. La obesidad puede ser considerada como una enfermedad inflamatoria sistémica crónica en adultos y en los jóvenes. El control del proceso de inflamación subclínica a través de la práctica de actividad física (AF) puede mitigar los efectos de los factores de riesgo que desencadenan la aterosclerosis, que empeora con la edad. El objetivo de este estudio fue realizar una revisión sistemática de los efectos de la actividad física y/o ejercicio sobre los marcadores cardiometabólicos y otros factores de riesgo de enfermedades cardiovasculares en adolescentes. La revisión sistemática se realizó en las bases de datos electrónicas Scopus, Pubmed, Conchrane Collection y SciELO. Los términos utilizados en la búsqueda fueron "cardiovascular diseases AND inflammation AND adolescents AND physical activity OR exercise". Fueron evaluados 24 artículos originales, 14 estudios longitudinales y 10 transversales. 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.

The significance of polyphenol intake for the prevention of chronic diseases is controversial. Objective: this study investigated the chemical composition and antioxidant potential of an anthocyanin-rich extract from Euterpe edulis fruits (LPEF) and its effects on liver steatosis in dyslipidemic apoE-/- knockout mice. Materials and methods: mice were divided into G1 (C57BL/6) standard diet; G2 (apoE-/-) standard diet, G3 (apoE-/-) 2% LPEF, G4 (apoE-/-) 6% LPEF, G5 (apoE-/-) 10% LPEF, G6 (apoE-/-) 2% α-tocopherol acetate. After 75 days of treatment, the animals were euthanized. The LPEF contained a high level of monomeric anthocyanins (301.4 mg/100g) and marked antioxidant activity. Results: Catalase activity was reduced in G3, G4, G5 and G6 compared to G2. Superoxide dismutase was reduced only in G4. The animals in G4, G5, and G6 showed low HDL and triglycerides levels compared to G2. The proportion of lipid droplets in liver tissue was reduced in G4 and G5 compared to G2, G3, and G6. Conclusion: The results indicated that E. edulis pulp is rich in anthocyanins and the LPEF dietary consumption can reduce the severity of liver steatosis in apoE-/- mice, an effect that is potentially mediated by the antioxidant activity of this extract and modulation of triglyceride serum levels.

El papel de los polifenoles en la prevencion de enfermedades cronicas es controvertido. Objetivo: este estudio investigo la composicion quimica y el potencial antioxidante de un extracto del fruto de Euterpe edulis rico en antocianinas (LPEF) y sus efectos en la esteatosis hepatica en ratones apoE-/- knockout con dislipidemia. Material y metodos: los ratones fueron divididos en los siguientes grupos; G1 (C57BL/6) con una dieta estandar; G2 (apoE-/-) con dieta estandar; G3 G3 (apoE-/-) con 2% de LPEF; G4 (apoE-/-) con 6% de LPEF; G5 (apoE-/-) con 10% de LPEF y G6 (apoE-/-) con 2% acetato α-tocoferol (α-tocopherol acetate). Despues de 75 dias de tratamiento, los animales fueron eutanizados. El LPEF contenia un alto nivel de antocianinas monomericas (301,4 mg/100 g) con notable actividad antioxidante. Resultados: la actividad catalasa fue reducida en los grupos G3, G4, G5 y G6 comparada con G2. La superoxidasa dismutasa solo se redujo en el grupo G4. Los animales de G4, G5 y G6 mostraron bajos niveles de HDL trigliceridos, comparados con G2. La proporcion de lipidos en el tejido hepatico fue reducida en G4 y G5, comparado con G2, G3 y G6. Conclusion: los resultados indicaron que la pulpa de E. edulis es rica en antocianinas, y que el consumo de LPEF en la dieta puede reducir la severidad de la esteatosis hepatica en ratones apoE-/-, un efecto que es potencialmente mediado por la actividad antioxidante de este extracto y la modulacion en los niveles sericos de trigliceridos.

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.
