Abstract Background The COVID-19 pandemic has changed food consumption. Objective Evaluate the association between metabolic phenotypes, changes in food consumption during the pandemic, and health outcomes in obese women. Methods Cross-sectional observational study including 491 women without previous diagnosis of chronic diseases, evaluated according to metabolic phenotype. During the pandemic, a subsample was re-evaluated by online questionnaires via Google Forms. Analyzed anthropometric, biochemical, and dietary data as well as health outcomes (coronary artery disease, type 2 diabetes, hypertension, dyslipidemia or death). Information on mortality was collected from the Internal Affairs Office of the State of Rio de Janeiro and the Health Department of the State of Rio de Janeiro. Statistical analysis was performed using the statistical program SPSS 21, with Mann-Whitney test, Pearson’s chi-squared, Spearman correlation, and binary logistic regression, at a significance level of 5%. Results The anthropometric, glucose, and lipid profiles showed significant differences between the metabolically healthy and metabolically unhealthy groups (p = 0.00). Before the pandemic, women in the metabolically unhealthy group had higher dietary intakes of lipids (p = 0.01), saturated fat (p = 0.01) and sodium (p = 0.04), during the pandemic, they consumed more energy (p = 0.04), lipids (p = 0.02), saturated fat (p = 0.02), proteins (p = 0.03) and sodium from ultra-processed foods (p = 0.03). Consequently, health outcomes were more prevalent in the metabolically unhealthy group (p = 0.00). Conclusion Observed that metabolically healthy women had qualitatively better food intake and fewer health outcomes throughout the study.

Abstract Background Dietary treatment containing fiber-rich foods may contribute to lowering weight in obese women. Objective To investigate the effect of a hypoenergetic diet combined with pumpkin seed flour (PSF) consumption on diet quality, anthropometric indices, and glucose and lipid metabolism in obese women. Methods We conducted a randomized, double-blind, placebo-controlled, 90-day clinical trial with obese women, distributed into the following two groups: hypoenergetic diet + placebo (PG) and hypoenergetic diet + pumpkin seed flour (PSFG). A total of 100 participants were included in the PSFG (n = 47) and PG (n = 53). We evaluated neck circumference (NC); waist to height ratio; conicity index; fat mass (FM); lipid profile; blood concentrations of glucose and insulin; homeostatic model assessment for insulin resistance (HOMA-IR); quantitative insulin sensitivity check index (QUICKI); and blood pressure at baseline, 30, 60, and 90 days. Dietary analysis was determined by differences between diet quality indices before and after prescribing the experimental diet. Chi-squared, Student’s t-tests and analysis for repeated measures were used, and values were considered significant at p < 0.05. Results The dietary pattern improved after 90 days in both groups. The PSFG presented lower NC (p < 0.001), FM (p = 0.010), triglycerides (TG) (p = 0.025), insulin (p = 0.003), and HOMA-IR (p = 0.018). The PG presented a lower diastolic blood pressure (p = 0.004) and low-density lipoprotein cholesterol (LDL-c) (p = 0.056). Conclusion A hypoenergetic diet combined with PSF consumption contributes to lowering NC, FM, HOMA-IR, TG, and insulin concentrations.

Abstract Introduction: Currently, two types of phenotypes have been recognized in individuals who are obese. Among the factors related to lifestyle, diet has a relevant influence, although there is no consensus regarding the role of diet in metabolic phenotypes; furthermore, diet is a strong moderator of chronic systemic inflammation. Objective: Investigate dietary inflammatory potential between metabolic phenotypes and to compare the differences between anti-inflammatory and pro-inflammatory diets in individuals with the same phenotype. Methods: This is a cross-sectional observational study that utilized the database of 533 individuals divided into 4 groups, according to metabolic phenotype and dietary inflammatory characteristic. Sociodemographic, clinical, anthropometric and biochemical characteristics were evaluated and the inflammatory index of the diet was calculated. Results: The mean Dietary Inflammatory index (DII) of the total sample was 0.974±1.02, with a maximum of 4.34 and a minimum of −1.74. In the metabolically unhealthy groups, we found a statistical difference in relation to systolic blood pressure when comparing the anti-inflammatory [median 120 (110.0-130.0)] and pro-inflammatory diets [median 130 (120.0-140.0); p = 0.022], and mean isoprostane concentrations were lower in the metabolically healthy group with anti-inflammatory diet. In regression analysis, the only variable that demonstrated a higher risk of alterations in all groups when compared to the metabolically healthy and anti-inflammatory group were isoprostane concentrations. Conclusion: We are able to conclude that an anti-inflammatory diet is associated with lower oxidative stress in metabolically healthy obese, and a pro-inflammatory diet is associated with higher systolic blood pressure values.

Abstract Introduction: Vegetarian diets have favorable effects on cardiovascular risk, provided that they do not contain ultra-processed foods (UPF). Objective: To compare the metabolic profile, cardiovascular risk, body composition, and food consumption in vegan (VEG), lacto-ovo vegetarian (LOV), and omnivorous (OMNI) women. To verify the association between UPF consumption and cardiovascular risk. Methods: Cross-sectional study with 119 VEG (n = 43), LOV (n = 38), and OMNI (n = 38) women. Anthropometric and biochemical parameters and the Framingham risk score were assessed. Food consumption was assessed by means of a 3-day food register, and intake of macronutrients, micronutrients, and UPF was estimated. The correlation between UPF consumption and cardiovascular risk was assessed using Spearman's coefficient, with a significance level of 5%. Results: The groups showed low cardiovascular risk, without significant difference between them. The VEG and LOV groups had lower body mass index, neck circumference, body shape index, and systolic blood pressure (p < 0.05) than the OMNI group; greater consumption of carbohydrates, sugars, dietary fibers, micronutrients, beta-carotene, and carotenoids; and lower consumption of total fat, saturated fatty acids, and cholesterol (p < 0.05). Consumption of UPF was lower in the LOV group (5.7 [0.0– 19.8]) than in the OMNI group (14.9 [5.1 – 22.3]; p < 0.05). UPF consumption was associated with SBP (ρ = 0.439; p = 0.007) and blood sugar (ρ = 0.422; p = 0.010) in the VEG group, and in the LOV group it was inversely associated with LDL-c (ρ = −0.456; p = 0.010). Conclusion: Vegetarian women showed better body composition and dietary quality than OMNI women. It is important to take consumption of UPF in vegetarians into consideration, in order to improve cardiovascular risk in women.

Resumo Fundamento: A obesidade é reconhecida como um fator de risco importante no desenvolvimento de várias complicações metabólicas. Porém, alguns indivíduos obesos apresentam um perfil metabólico favorável. Objetivo: O objetivo do presente estudo foi identificar um parâmetro fácil para reconhecer mulheres obesas metabolicamente saudáveis (OMS) Métodos: Foram selecionadas 292 mulheres não diabéticas com índice de massa corporal (IMC) ≥ 30 kg/m2 e a coorte final foi composta de 239. De acordo com o estado metabólico determinado pelo modelo de avaliação da homeostase (HOMA), as participantes foram classificadas como obesas metabolicamente saudáveis (OMS) ou obesas metabolicamente não saudáveis (OMNS). Compararam-se ambos os grupos quanto às características bioquímicas, antropométricas e de composição corporal. Resultados: A idade média da coorte foi de 43,9 ± 10,9 anos e o IMC médio foi 37,2 ± 5,3 kg/m2. No total, 75,7% das participantes foram classificadas como OMS pelo HOMA. O ponto de corte para a circunferência da cintura (CC) de 108,2 identificou mulheres OMS com sensibilidade de 72,4% (intervalo de confiança [IC] de 95%: 59,8-82,3%), especificidade de 66,9% (IC 95%: 59,71-73,3%) e razão de verossimilhança negativa (RVN) de 0,41 (IC 95%: 0,36-0,47). Adicionalmente, o ponto de corte de 99,2 para o índice de adiposidade visceral (IAV) identificou mulheres OMS com sensibilidade de 89,7% (IC 95%: 79.2-95.2%), especificidade de 48,6% (IC 95%: 41,4-55,9%) e RVN de 0,21 (IC 95%: 0.15-0.30). Conclusões: Mulheres classificadas como OMS apresentaram menor CC, menor percentual de gordura corporal e menores níveis séricos de glicose e de insulina. A CC foi identificada como um parâmetro fácil para identificar mulheres OMS.

Abstract Background: Obesity is recognized as a major risk factor for the development of several metabolic complications. However, some obese individuals have a favorable metabolic profile. Objective: The aim of this study was to identify an easy parameter for recognizing metabolically healthy obese (MHO) women. Methods: A total of 292 non-diabetic women with a body mass index (BMI) ≥ 30 kg/m2 were selected, and 239 composed the final cohort. We classified the participants according to their metabolic state determined by homeostasis model assessment (HOMA) into MHO or metabolically unhealthy obese (MUO). Both groups were compared regarding biochemical, anthropometric, and body composition characteristics. Results: The average age of the cohort was 43.9 ± 10.9 years and the average BMI was 37.2 ± 5.3 kg/m2. In total, 75.7% of the participants were classified as MHO by HOMA. A cutoff of 108.2 cm for waist circumference (WC) identified MHO participants with a sensitivity of 72.4% (95% confidence interval [CI]: 59.8-82.3%), specificity of 66.9% (95% CI: 59.71-73.3%), and negative likelihood ratio of 0.41 (95% CI: 0.36-0.47). Additionally, a visceral adiposity index cutoff value of 99.2 identified MHO women with a sensitivity of 89.7% (95% CI: 79.2-95.2%), specificity of 48.6% (95% CI: 41.4-55.9%), and negative likelihood ratio of 0.21 (95% CI: 0.15-0.30). Conclusion: Women classified as MHO exhibited smaller WC measurements and lower body fat percentages, as well as lower blood glucose and insulin levels. WC emerged as an easy parameter for identifying MHO women.

Abstract Background: The eggplant (Solanum melongena) is a fruit of world consumption. Its processing in the form of flour is a way to avoid losses and to take advantage of its nutritional characteristics. Objective: This study assessed the physicochemical composition (moisture, proteins, lipids, crude fiber, carbohydrates, minerals, niacin, saponins, titratable acidity, dietary fiber, and total phenols) of eggplant flour prepared from the whole fruit dehydrated in an oven. Methods: In vitro antioxidant activity was assessed using the following methods: 2.2-diphenyl-1-picrylhydrazyl radical (DPPH); Ferric Reducing/Antioxidant Power (FRAP); and analysis of polyphenols using HPLC (chlorogenic acid, caffeic acid, ferulic acid, and rutin). Results: It was possible to observe: 23.09% carbohydrates; 13.34% proteins; 1.85% lipids; 39.19% total fibers; 1,540 mg/100 g total soluble phenolic compounds; 840 mg/100 g saponins; minerals (potassium, magnesium, copper, iron, zinc, manganese); and niacin. In vitro antioxidant activity was observed through DPPH (455.6 mg ascorbic acid/100 g) and FRAP (486.8 mg ascorbic acid/100 g). The HPLC method determined the presence of ascorbic acid, tyrosine, and phenolic acids (chlorogenic acid, caffeic acid, and ferulic acid). Conclusion: The eggplant flour had great fiber content in addition to good content of phenolic compounds and saponins with important antioxidant capacity observed through in vitro assays. As a result, eggplant flour is a good addition to the diet of the population, since it can bring potential health benefits.

Background: In order to prevent chronic, non communicable disease, it is essential that lifestyle is modified to include a diet high in fiber. Aim: To assess the effect oat bran (OB) in conjunction with nutrition counseling (NC) have on lipid and glucose profile, anthropometric parameters, quality of diet, and ingestion of ultraprocessed foods (UPF) and additives in hypercholesterolemia sufferers. Method: This was a 90-day, double-blind, placebo-controlled, block-randomized trial undertaken on 132 men and women with LDL-c ≥ 130 mg/dL. The participants were sorted into two groups: OB Group (OBG) and Placebo Group (PLG), and were given NC and 40g of either OB or rice flour, respectively. Lipid and glucose profile were assessed, as were the anthropometric data, quality of diet (Diet Quality Index revised for the Brazilian population - DQI-R) and whether or not UPF or additives were consumed. Results: Both groups showed a significant decrease in anthropometric parameters and blood pressure, as well as a significant reduction in total and LDL cholesterol. There was also an improvement in DQI-R in both groups and a decrease in consumption of UPF. Blood sugar, HOMA-IR and QUICKI values were found to be significantly lower only in the OBG. Conclusion: Our findings in lipid profile and anthropometric parameters signify that NC has a beneficial effect, which is attributable to the improved quality of diet and reduced consumption of UPF. Daily consumption of 40 g of OB was found to be of additional benefit, in decreasing insulin-resistance parameters.

Antecedentes: con el fin de prevenir la enfermedad crónica, no transmisible, es esencial que el estilo de vida se modifique para incluir una dieta alta en fibra. Objetivo: evaluar el efecto de la harina de avena (DE) en conjunto con consejos de nutrición (NC) sobre el perfil lipídico y glucémico, los parámetros antropométricos, la calidad de la dieta, y la ingestión de alimentos ultraprocesadas (UPF) y aditivos en los enfermos de hipercolesterolemia. Método: se realizó un ensayo de 90 días, doble ciego, controlado con placebo, aleatorizado realizado en 132 hombres y mujeres con c-LDL ≥ 130 mg/dl. Los participantes fueron clasificados en dos grupos: DE Group (OBG) y el grupo placebo (PLG), y se les dio NC y 40 g de DE o de harina de arroz, respectivamente. Se evaluó el perfil lipídico y la glucemia, así como los datos antropométricos, la calidad de la dieta (Índice de Calidad de la dieta revisada para la población brasileña ICD-R) y si se consumieron UPF o aditivos. Resultados: ambos grupos mostraron una disminución significativa en los parámetros antropométricos y la presión arterial, así como una reducción significativa en el colesterol total y LDL. También hubo una mejora en la ICD-R en ambos grupos y una disminución en el consumo de la UPF. La glucemia, HOMA-IR, y QUICKI fueron significativas en inferiores sólo en el grupo que consumió salvado de avena. Conclusión: nuestros hallazgos sobre las modificaciones en el perfil lipídico y en los parámetros antropométricos significan que los consejos nutricionales tienen un efecto beneficioso, que es atribuible a la mejoría en la calidad de la dieta y al menor consumo de alimentos ultraprocesados. El consumo diario de 40 g de salvado de avena proporciona un beneficio adicional, al disminuir los parámetros de resistencia insulínica.

Introduction: chia is a seed rich in such nutrients as proteins, n-3 fatty acids and especially alpha-linolenic acid (ALA), minerals, fibers and antioxidants. Efforts have been made to assess whether human consumption of chia can reduce cardiovascular risk factors; however, it has not been established as effective and the findings of the few studies to have looked into the matter are inconsistent. Aim: to systematize the findings of studies assessing the effect the consumption of chia seed, either milled or whole, has in the prevention/control of cardiovascular risk factors in humans. Methods: this is a systematic literature review (SLR) with no meta-analysis. The articles scrutinizedwere identified in the electronic databases Lilacs, Medline (Pub- Med version), Cochrane, Scielo, Scopus, and Web of Science under the keywords "dyslipidemia" or "dislipidemia", "hyperlipidemia" or "hiperlipidemia", "obesity" or "obesidade", "salvia" or "salviahispanica", "Lamiaceae" or "chia", "hypertension" or "hipertensão", "hypertrygliceridemia" or "hipertrigliceridemia", and "riscocardiovascular" or "cardiovascularrisk." We chose for our selection English-, Portuguese- or Spanish-language articles about clinical trials on humans and published within the last ten years. The biases of risk analysis were carried out considering 6 of the 8 criteria of the Cochrane Handbook for Systematic Reviews of Interventions Version 5.1. Findings: seven studies (n = 200) fit our inclusion criteria. Of the chosen clinical trials, only one was not randomized. Five of the studies were blind experiments. Two of the studies were acute trials, both of them randomized. Of the chia seed interventions, one study showed a significant drop in systolic blood pressure (SBP) and inflammatory markers, yet there was no change in body mass, lipid profile or blood sugar. In four of the studies reviewed there was a significant spike in ALA and eicosapentaenoic acid (EPA), with no significant change to other parameters. In the acute trials, post-prandial blood hipertriglisugar was significantly lower. Only one study showed a significant drop in triglycerides (TG), body mass and inflammatory markers; however, the chia seed in that case was mixed with other foods. Most of the studies showed unclear or low risk of bias. Two studies showed a high risk of bias because not all the pre-specified primary outcomes were reported in the findings. Conclusion: most of the studies did not demonstrate statistically significant results in relation to cardiovascular disease (CVD) risk factors. The evidence regarding the relationship between chia seed consumption and cardiovascular risk factors are insufficient, and the studies included in this review present numerous limitations. Further research is hence needed.

Introducción: la chía es una semilla rica en nutrientes tales como proteínas; ácidos grasos omega 3, especialmente ácido alfa-linolénico (ALA); minerales; fibras y antioxidantes. Se han hecho esfuerzos para evaluar si el consumo humano de chía puede reducir los factores de riesgo cardiovascular; sin embargo, no se ha establecido como eficaz y los resultados de los pocos estudios que han examinado la cuestión son incompatibles. Objetivo: sistematizar los hallazgos de los estudios que evaluaron el efecto del consumo de la semilla de chía, ya sea molida o entera, tiene en la prevención/control de los factores de riesgo cardiovascular en los seres humanos. Métodos: se trata de una revisión sistemática de la literatura (SLR), sin metaanálisis. Los artículos escrutados eran identificados en las bases de datos Lilacs electrónicos, Medline (PubMed versión), Cochrane, Scielo, Scopus y Web of Science bajo la palabra clave "dyslipidemia" o "dislipidemia", "hyperlipidemia" o "hiperlipidemia", "obesity" o "obesidade", "salvia" o "salviahispanica", "Lamiaceae" o "chia", "hypertension" o "hipertensão", "hypertrygliceridemia" o "hipertrigliceridemia" y "riscocardiovascular" o "cardiovascularrisk". Elegimos para nuestra selección artículos en inglés, portugues o español sobre ensayos clínicos en seres humanos publicados en los últimos diez años. Los sesgos de análisis de riesgo se realizaron considerando seis de los ocho criterios del Manual Cochrane para Revisiones Sistemáticas de Intervenciones Versión 5.1. Resultados: siete estudios (n = 200) encajan con los criterios de inclusión. De los ensayos clínicos seleccionados, solo uno no fue aleatorio. Cinco de los estudios fueron experimentos ciegos. Dos de los estudios eran ensayos agudos, ambos asignados al azar. De las intervenciones de semillas de chía, un estudio mostró una disminución significativa de la presión arterial sistólica (PAS) y los marcadores de inflamación; sin embargo, no hubo cambios en la masa corporal, el perfil de lípidos o el azúcar en sangre. En cuatro de los estudios revisados no había un pico significativo en ALA y ácido eicosapentaenoico (EPA), ni ningún cambio significativo en otros parámetros. En los ensayos agudos, el nivel postprandial de azúcar en sangre fue significativamente menor. Solo un estudio mostró un descenso significativo de los triglicéridos (TG), la masa corporal y los marcadores inflamatorios; sin embargo, la semilla de chía en ese caso se mezcló con otros alimentos. La mayoría de los estudios mostraron riesgos claros o bajo sesgo. Dos estudios mostraron un alto riesgo de sesgo, porque no todos los resultados primarios preespecificados fueron reportados en los hallazgos. Conclusión: la mayoría de los estudios no demostraron resultados estadísticamente significativos en relación con los factores de riesgo cardiovascular (ECV). La evidencia sobre la relación entre el consumo de semillas de chía y los factores de riesgo cardiovascular son insuficientes, y los estudios incluidos en esta revisión presentan numerosas limitaciones. Por lo tanto, se necesita más investigación.

Introduction: the prevalence of obesity has increased, especially among women. Aim: the aim of this study was to assess the effect of a hypoenergetic diet combined with coconut flour on anthropometric and biochemical data and the quality of the diet. Methods: we carried out a crossover clinical trial involving a step with hypoenergetic diet only and another with the diet associated with coconut flour consumption (26 g) over the course of nine months. The volunteers were recruited from the São Gonçalo city of Rio de Janeiro. Anthropometric, biochemical and dietary data were collected monthly. The diet quality index revised for the Brazilian population (DQI-R) and the consumption of ultra-processed foods and additives were assessed. The Wilcoxon and Mann-Whitney tests were performed, with p < 0.05 considered statistically significant. Results: forty-two women of an average 47.5 ± 9.5 years of age participated. The hypoenergetic diet promoted a decrease in body fat, body mass index, waist circumference, waist-to-height ratio, visceral adiposity index, diastolic blood pressure, triglycerides and VLDL. The consumption of coconut flour promoted a drop in glucose and total cholesterol levels when supplementing the hypoenergetic diet. The improvement to diet quality can be noted in the decrease in consumption of ultra-processed foods like vegetable oil, chocolate and soft drinks. Conclusion: the hypoenergetic diet promoted a decrease in the anthropometric parameters, blood pressure and triglycerides. The consumption of coconut flour promoted a decrease in glucose and total cholesterol levels when supplementing the hypoenergetic diet. The improved diet quality can be seen in the decrease in consumption of ultra-processed foods.

Introducción: la prevalencia de la obesidad ha aumentado, sobre todo entre las mujeres. Objetivo: el objetivo de este estudio fue evaluar el efecto de una dieta hipoenergética combinada con harina de coco en los datos antropométricos y bioquímicos y, así como la calidad de la dieta. Métodos: se realizó un ensayo clínico cruzado que incluyó un paso solo con dieta hipoenergética y otro con la dieta asociada con el consumo de harina de coco (26 g) a lo largo de nueve meses. Los voluntarios fueron reclutados de la ciudad de São Gonçalo de Río de Janeiro. Antropométrica, datos bioquímicos y dietéticos fueron recolectados mensualmente. Fueron evaluados el índice de calidad de la dieta revisado para la población brasileña (ICD-R) y el consumo de alimentos y aditivos ultraprocesados. Se realizaron las pruebas de Wilcoxon y Mann-Whitney, con p < 0,05, considerado estadísticamente significativo. Resultados: participaron cuarenta y dos mujeres con un promedio de 47,5 ± 9,5 años de edad. La dieta hipoenergética promovió una disminución de la grasa corporal, el índice de masa corporal, la circunferencia de la cintura, la relación cintura-talla, el índice de adiposidad visceral, la presión arterial diastólica, los triglicéridos y VLDL. El consumo de harina de coco promovió una caída en los niveles de colesterol y glucosa totales al complementar la dieta hipoenergética. La mejora de la calidad de la dieta puede observarse en la disminución del consumo de alimentos ultraprocesados como el aceite vegetal, el chocolate y los refrescos. Conclusión: la dieta hipoenergética promovió una disminución en los parámetros antropométricos, la presión arterial y los triglicéridos. El consumo de harina de coco favoreció una disminución de los niveles de colesterol yde glucosa totales cuando se complementa la dieta hipoenergética. La calidad de la dieta mejorada se puede ver en la disminución del consumo de alimentos ultraprocesados.

Introduction: saturated fat restriction has been recommended for coronary arterial disease, but the role of coconut oil (Cocos nucifera L.) extra virgin, lauric acid source in the management of lipid profile remains unclear. Objective: to evaluate the effect of nutritional treatment associated with the consumption of extra virgin coconut oil in anthropometric parameters and lipid profile. Methods: we conducted a longitudinal study of 116 adults of both sexes presenting CAD. Patients were followed in two stages: the first stage (basal-3 months), intensive nutritional treatment. In the second stage (3-6 months), the subjects were divided into two groups: diet group associated with extra virgin coconut oil consumption (GDOC) and diet group (DG). Held monthly anthropometric measurements: body mass, waist circumference (WC), neck circumference (PP), body mass index (BMI). Gauged to collected blood pressure and blood samples were fasted for 12 hours, for total cholesterol analysis and fractions apoproteins (Apo A-1 and B), glucose, glycated hemoglobin (HbA1C), insulin (I). Comparing the averages at the beginning and end of the study employing the paired Student t-independent. And set the diastolic blood pressure by BMI using ANOVA. Analyses were performed using the SPSS statistical package, being significant p < 0.05. Results: the mean age of the population was 62.4 ± 7.7 years, 63.2% male, 70% elderly, 77.6% infarcted, 52.6% with angina, hypertension and dyslipidemia 100%. In the first stage the nutritional treatment reduced body weight, WC, BMI and PP and insulin concentrations, HbA1C, HOMA-IR and QUICK, without changing the other parameters. In the second stage of the study, it was observed that the GDOC maintained the reduction of body mass, BMI, WC, with a significant difference between groups for DC (-2.1 ± 2,7cm; p < 0.01). In addition, there was an increase in HDL-C concentrations, Apo A, with significant difference in GD, only for HDL-C (3.1 ± 7.4 mg/dL; p = 0.02). Conclusion: it was observed that the nutritional treatment associated with extra virgin coconut oil consumption reduced the CC and increased HDL-C levels in patients with CAD.

Introducción: el aceite de coco (Cocos nucifera L.) virgen extra contiene una alta proporción de ácidos grasos de cadena media que parecen contribuir a la reducción del peso y podría ayudar en la prevención secundaria de la enfermedad arterial coronaria (EAC). Objetivo: evaluar el efecto del tratamiento nutricional asociado con el consumo de aceite de coco virgen extra en los parámetros antropométricos y el perfil lipídico. Métodos: se realizó un estudio longitudinal de 116 adultos de ambos sexos que presentan CAD. Los pacientes fueron seguidos en dos etapas: en la primera etapa (basal-3 meses), se llevo a cabo un tratamiento nutricional intensivo. En la segunda etapa (3-6 días), los sujetos fueron divididos en dos grupos: grupo asociado con el consumo de aceite extra virgen de coco (GDOC) y el grupo de dieta (GD). Se realizaron mediciones mensuales antropométricas: peso, circunferencia de la cintura (CC), circunferencia del cuello (PP) e índice de masa corporal (IMC). Se tomó la presión arterial y muestras de sangre recogidas en ayunas durante 12 horas para el análisis de colesterol total y lipoproteínas, apoproteínas (Apo A-1 y B), glucosa, hemoglobina glucosilada (HbA1c) e insulina (I). Se compararon los promedios al principio y al final del estudio mediante el test t de Student-independiente. Se ajustó la presión arterial diastólica por el IMC mediante ANOVA. Los análisis se realizaron con el paquete estadístico SPSS, siendo significativa p < 0.05. Resultados: la edad media de la población fue de 62,4 ± 7,7 años, el 63,2% hombres, 70% mayores, el 77,6% con infarto de miocardio, el 52,6% con angina de pecho y el 100% con hipertensión arterial y dislipidemia. En la primera etapa del tratamiento nutricional se redujeron las concentraciones de insulina, peso, WC, IMC y PP, HbA1C, HOMA-IR y rápido, sin cambiar otros parámetros. En la segunda etapa del estudio se observó que la GDOC mantiene la reducción del peso, BMI, WC, con una diferencia significativa entre los grupos para DC (-2,1 ± 2,7 cm; p < 0,01). Además, se produjo un aumento en las concentraciones de HDL-C, Apo A, con una diferencia significativa en GD, solo para HDL-C (3,1 ± 7,4 mg/dl; p = 0,02). Conclusión: se observó que el tratamiento nutricional asociado con el consumo de aceite de coco virgen extra redujo la CC e incrementó los niveles de HDL-C en pacientes con CAD.

The effectiveness of nutritional treatment is important protective factor for the prevention of recurrences of cardiovascular diseases. The goal of this study was to assess the effectiveness of nutritional treatment and to know the eating pattern and the quality of an adjuvant diet for optimized clinical treatment in patients with chronic coronary artery disease (CCAD). This is a clinical trial with a three-month duration conducted with 116 patients of both sexes with (CCAD) in secondary prevention. The patients underwent nutritional treatment and blood pressure, anthropometric, biochemical and dietetic (24-hour recall) measures were collected. The Brazilian Healthy Eating Index (BHEI-R) was calculated for assessing diet quality. The average age was 62.5 ± 7.8 years. The nutritional treatment reduced: weight -1.5 ± 2.3 kg; p < 0.01; body mass index -0.5 ± 0.9 kg/m2; p < 0.01; waist circumference -2.0 ± 0.1cm; p < 0.01; neck circumference -0.8 ± 0.1; p < 0.01 cm; concentrations of plasma insulin -1.3 ± 0.5mU/ mL p < 0.03, glycated hemoglobin -0.4 ± 0.1 mg/dL; p < 0.01 (- 0,004 mmol/L), and HOMA-IR (-0.8 ± 3.9; p < 0.03); and increased insulin sensitivity 6.64 ± 23,9 x10-3; p < 0.01. The nutritional treatment increased HDL-cholesterol concentrations in patients who adhered to the diet after BHEI-R control 1.7 ± 1.4 mg/dL; p = 0.04 (0,04 mmol/L). Three-month nutritional treatment promoted reduction of saturated fats consumption (-1.9 ± 0.5%; p=<0.01), cholesterol (-67.7 ± 18.6 mg/d; p < 0.01), and sodium (815.2 ± 146.5 mg/d; p < 0.01); and 20.7% of the patients finished the study with a healthy diet. The intensive nutritional treatment was effective in reducing anthropometric measures and improving glycemic control.

La eficacia del tratamiento nutricional es un factor de protección importante para la prevención de la enfermedad cardiovascular recurrente. El objetivo del estudio fue evaluar la eficacia del tratamiento nutricional y para cumplir con el estándar de la comida y la calidad de la dieta adyuvante para el tratamiento médico óptimo en pacientes con enfermedad de la arteria coronaria crónica (EACC). Esta es una prueba que dura tres meses realizado con 116 pacientes de ambos sexos (EACC) en la prevención secundaria. Los pacientes fueron sometidos a tratamiento nutricional y se recogieron la presión arterial, las mediciones antropométricas, (24 horas, recuerdo) y las medidas bioquímicas y dietéticas. Se utilizó el índice Brasileño de Calidad de la Dieta (ICD-R) para evaluar la calidad de esta. La edad media fue de 62,5 ± 7,8 años. El tratamiento nutricional baja: -1,5 ± 2,3 kg; p < 0,01; índice de masa corporal -0,5 ± 0,9 kg/m2; p < 0,01; circunferencia de la cintura -2,0 ± 0,1 cm; p < 0,01; circunferencia del cuello -0,8 ± 0,1cm; p < 0,01; concentraciones de insulina en plasma -1,3 ± 0.5mU/ml; p < 0,03, hemoglobina glucosilada 0,4 ± 0,1 mg/dl; p < 0,01 (-0,004 mmol/L) HOMA-IR (-0,8 ± 3,9; p < 0,03) y una mayor sensibilidad a la insulina 23,9 ± 6,64x10-3; p < 0,01. El tratamiento nutricional aumentó las concentraciones de colesterol HDL en los pacientes que se adhirieron a la dieta después de ICD-R 1,7 ± 1,4 mg/dl; p = 0,04 (0,04 mmol/L). Tres meses de tratamiento redujeron la ingesta nutricional de grasas saturadas (-1,9 ± 0,5%, p=<0,01), colesterol (-67,7 ± 18,6 mg/d; p < 0,01) y sodio (815,2 ± 146,5 mg/d; p < 0,01); y el 20,7% de los pacientes completó el estudio con una dieta saludable. El tratamiento nutricional intensivo fue eficaz en la reducción de las medidas antropométricas y a la hora de conseguir un mejor control glucémico.

Background: Selenium (Se) is an essential micronutrient that performs physiological functions in the metabolism of thyroid hormone and may have an association with anthropometric variables relevant to cardiovascular disease. Aim: To study the associations between Se status, thyroid hormones and anthropometric variables in dyslipidemic patients. Methods: Eighty-three patients were assessed in a cross-sectional study. Blood samples were analyzed for Se and thyroid hormones. Anthropometric measurements were taken, and dietary Se intake was investigated. Results: Mean plasma Se concentrations were low in the patients, at 88.7 ± 16.7 μg/L. Patients with plasma Se ≥ 95 μg/L were found to have a higher body mass index (BMI) (30.74 �± 4.31 vs 27.68 �± 5.63 kg/m², P = 0.02) and waist-to-height ratio (0.65 �± 0.05 vs 0.59 �± 0.07, P = 0.003) when compared to those with concentrations between 80 and 94 μg/L. Se intake associated positively with T3L/T4L ratio (r = 0.273; P= 0.03), BMI (r= 0.257, P= 0.04) and WC (r= 0.299, P= 0.02). Conclusion: The patients with the highest normal plasma Se concentrations were found to have increases in the anthropometric variables we investigated. There is a need for further study in order to elucidate these findings. Furthermore, we found a positive association between Se intake and the most metabolically active form of the thyroid hormones.

Contexto: El selenio (Se) es un micronutriente esencial que realiza las funciones fisiologicas en el metabolismo de la hormona tiroidea y pueden tener una asociacion con las variables antropometricas pertinentes a la enfermedad cardiovascular. Objetivo: Estudiar la asociacion entre el estado de Se, hormonas tiroideas y las variables antropometricas en pacientes con dislipidemia. Metodos: Ochenta y tres pacientes fueron evaluados en un estudio transversal. Se analizaron muestras de sangre para Se y hormonas tiroideas. Las medidas antropometricas fueron tomadas, y la ingesta de la dieta Se fue investigado. Resultados: La media de las concentraciones de Se en plasma fueron bajas en los pacientes, a 88,7 �± 16,7 mg / l. Se encontro que los pacientes con niveles plasmaticos de Se ≥ 95 mg / L de tener un indice de masa corporal (IMC) (30.74 �± 4.31 vs 27.68 �± 5.63 kg / m², P = 0,02) y la relacion cintura-estatura (0,65 ± 0,05 vs 0,59 �± 0,07, P = 0,003) en comparacion con aquellos con concentraciones entre 80 y 94 g / l. Ingesta de Se asocio positivamente con relacion T3L / T4L (r = 0,273, p = 0,03), indice de masa corporal (r = 0,257, P = 0,04) y WC (r = 0,299, P = 0,02). Conclusion: Se encontro que los pacientes con las mas altas concentraciones de Se en plasma normal tener incrementos en las variables antropometricas que investigamos. Hay una necesidad de un mayor estudio para dilucidar estos hallazgos. Ademas, se encontro una asociacion positiva entre el consumo de Se y la forma mas metabolicamente activa de las hormonas tiroideas.

Obesity and insulin resistance are associated with an increase of cardiovascular risk factors, including adipocytokines. The aim of this study was to investigate the effect of low-calorie diet on serum lipids, adipokines, insulin resistance and body composition in obese women. It was a clinical trial with class I obese women aged 30-45 years submitted to hypocaloric diet for 90 days. Dietary intake, anthropometric parameters, body composition, serum lipids, glucose, insulin, leptin, adiponectin, HOMA-IR and QUICKI indexes were evaluated at the baseline, 30, 60 and 90 days. There was 30% significant decrease in energy intake, and also decrease in body weight, body mass index and waist circumference (p < 0.01) throughout the treatment period. Despite the amount of lean body mass (kg) reduced in average, it was observed that lean body mass (%) had increased (p < 0.01) and that the amount of fat body mass (kg) had decreased significantly in the third month (p < 0.05). Systolic blood pressure reduced up to -5mmHg (p < 0.05) after 90 days. Was observed a decrease (p < 0.05) on serum insulin and HOMA-IR until the 60th day, while the serum adiponectin increased (p < 0.01) during treatment. Corroborating with the reduction of fat body mass and weight, serum leptin also reduced (p < 0.01). These results suggest that the short-term low-calorie diet reduces total body fat, mainly found in the abdominal region, and efficiently improve insulin sensitivity decreasing cardiovascular risk in obese women.

La obesidad y la resistencia a la insulina se asocian con un aumento de los factores de riesgo cardiovascular, incluyendo las adipocitocinas. El propósito de este estudio fue investigar el efecto de una dieta baja en calorías sobre los lípidos séricos, las adipocinas, la resistencia a la insulina y la composición corporal en mujeres obesas. Se trataba de un estudio clínico en mujeres con obesidad de clase I, con edades entre 30-45 años, sometidas a una dieta hipocalórica durante 90 días. Se evaluaron basalmente y a los 30, 60 y 90 días la ingesta dietética, los parámetros antropométricos, la composición corporal, los lípidos séricos, la glucosa, la insulina, la leptina, la adiponectina y los índices HOMA-IR QUICKI. Hubo un descenso significativo del 30 % en el consumo de energía y un descenso del peso corporal, el índice de masa corporal y la circunferencia de la cintura (p < 0,01) durante todo el periodo de tratamiento. A pesar de que se redujo en promedio la masa magra corporal (kg), se observó que la masa magra corporal (%) se incrementó (p < 0,01) y que la cantidad de masa corporal grasa (Kg) disminuyó significativamente al tercer mes (p < 0,05). La presión sanguínea sistólica se redujo en 5 mmHg (p < 0,05) a los 90 días. Observamos un descenso de la insulina sérica y del HOMA-IR en el día 60 (p < 0,05), mientras que la adiponectina sérica aumentó (p < 0,01) durante el tratamiento. Como corroboración de la reducción de la masa corporal grasa y del peso, la leptina sérica también se redujo (p < 0,01). Estos resultados sugieren que la dieta hipocalórica a corto plazo reduce la grasa corporal total, fundamentalmente en la región abdominal y mejora de forma eficiente la sensibilidad a la insulina disminuyendo el riesgo cardiovascular en mujeres obesas.

Background: The metabolic syndrome is related to the increase in cardiovascular diseases. Polyunsaturated fatty acids from fish oil help in reducing cardiovascular risk factors and are natural bindings of PPARy2. Objective: To evaluate the impact of hypocaloric diet associated with microencapsulated fish oil supplementation in women with metabolic syndrome. Methods: We conducted a randomized, single-blind and placebo-controlled clinical trial with adult women who presented metabolic syndrome (n = 30) for 90 days. The volunteers were divided into two groups: placebo group (n = 15) and microencapsulated fish oil group (n = 15) (3 g/day of microencapsulated fish oil containing 0.41 g/day of eico-sapentaenoic acid and decosahexaneoic acid). Anthropometric, body composition, clinical and laboratory parameters were assessed before and after the intervention. Paired t-test was used for comparisons within groups and Student's t-test for comparison between groups. We considered p < 0.05 as significant values. Results: The comparison between groups revealed a significant reduction of blood glucose, insulinemia and the homeostasis model assessment in the microencapsulated fish oil group after 90 days, as opposed to the placebo group. We also observed reduction of the systolic arterial pressure in the microencapsulated fish oil group. Conclusion: A hypocaloric diet associated with the consumption of microencapsulated fish oil was effective in reducing blood glucose, insulinemia and insulin resistance in women with MS.

Antecedentes: El síndrome metabólico se relaciona con un incremento de las enfermedades cardiovasculares. Los ácidos grasos poliinsaturados del aceite de pescado ayudan a reducir los factores de riesgo cardiovascular y son ligandos naturales del PPARy2. Objetivo: Evaluar el impacto de la dieta hipocalórica asociada con suplementación de aceite de pescado micro-encapsulado en mujeres con síndrome metabólico. Métodos: Realizamos un ensayo clínico de distribución aleatoria, simple ciego y controlado con placebo en mujeres adultas con síndrome metabólico (n = 30) durante 90 días. Se dividió a las voluntarias en dos grupos: el grupo placebo (n = 15) y el grupo con aceite de pescado microencapsulado (n = 15) (3 g/día de aceite de pescado microencapsulado que contienen 0,41 g/día de ácido eicosapentaenoico y de ácido decosahexaneoico). Se evaluaron parámetros antropométricos, clínicos y de laboratorio y la composición corporal antes y después de la intervención. Se emplearon la prueba t pareada para las comparaciones dentro de los grupos y la prueba t de Student para la comparación entre grupos. Consideramos valores significativos de p < 0,05. Resultados: La comparación entre grupos reveló una reducción significativa de la glucosa sanguínea, la insulinemia y la evaluación del modelo homeostático en el grupo de aceite de pescado microencapsulado tras 90 días, en comparación con el grupo placebo. También observamos una reducción de la presión arterial sistólica en el grupo con aceite de pescado microencapsulado. Conclusión: La dieta hipocalórica asociada con el consumo de aceite de pescado microencapsulado fue eficaz en la reducción de la glucosa sanguínea, la insulinemia y la resistencia a la insulina en mujeres con SM.

A deficiência de ácido fólico está associada às doenças crônicas não-transmissíveis, complicações na gestação e doenças neurodegenerativas. Objetivou-se discutir o papel do ácido fólico na prevenção de doenças, os aspectos epidemiológicos de sua deficiência, fortificação dos alimentos e suplementação medicamentosa. Realizou-se levantamento bibliográfico, consultando as bases de dados para a obtenção dos artigos completos: MedLine, SciELO, PubMed, Highwire Press e Science Direct. Foram selecionados estudos realizados com seres humanos publicados entre 2004 e 2010. O ácido fólico é importante para as reações de metilação do ácido desoxirribonucléico, prevenção da hiper-homocisteinemia e atua como antioxidante. A deficiência dessa vitamina é descrita em adolescentes, mulheres em idade fértil, gestantes e em idosos. Seu alcance pela dieta é difícil, sendo necessária a inclusão de alimentos fortificados ou suplementos. É importante avaliar o estado nutricional de ácido fólico dos indivíduos antes e após a adoção dessas estratégias, de modo a gerar subsídios para ela-boração de medidas governamentais mais adequadas e eficazes. Destacamos ainda a necessidade da reeducação nutricional para a população brasileira a fim de aumentar o consumo de alimentos fontes de ácido fólico.

Folic acid deficiency is associated with non-communicable chronic diseases, pregnancy-associated complications and neurodegenerative diseases. The objective of this paper was to discuss the role of folic acid in disease prevention, the epidemiological aspects of its deficiency and food fortification and supplementation. Articles were searched in the following databases: MedLine, SciELO, PubMed, Highwire Press and Science Direct. Only original studies with humans published between 2004 and 2010 were included. Folic acid is important for DNA methylation and prevention of hyperhomocysteinemia. It also presents antioxidant activity. Folic acid deficiency has been described in adolescents, women of childbearing age, pregnant women and the elderly. It is difficult to meet the folic acid requirement with diet alone, so fortified foods and supplements are necessary. It is important to assess folic acid levels before and after the implementation of such strategies to enable the development of better and more effective public strategies. It is also important to provide nutrition education for the Brazilian population for them to increase their consumption of dietary sources of folic acid.
