Almond baru (Dipteryx alata Vog.) Awakens scientific interest for its nutritional composition. The aim of this randomized controlled clinical trial was to evaluate the effect of consumption of almond baru associated normocaloric prescription on body composition, lipid profile and antioxidant enzymes activity in overweight women. The study included 46 overweight women who were prescribed normocaloric diet and were randomized into a placebo group (PG, n = 22, 800 mg maltodextrin) and intervention group (IG, n = 24, 20 g almonds baru ). Adiposity, blood pressure, serum lipids, biochemical parameters and enzyme activity of catalase, glutathione peroxidase (GPx) and superoxide dismutase (SOD) measurements were determined at baseline and at study completion. Statistical analysis was performed using Stata software for Windows (version 12.0). Comparisons of means and pre-and post-intervention differences between groups were analyzed by Student's t test. The pre-and post-intervention differences within groups were analyzed by t test for paired samples were significant p <0.05. Body mass decreased in GP and GI, however the reduction in adiposity was observed only in GI. The reduction in waist circumference was 1.7 times higher in GI, compared to GP (p = 0.01). The lipid composition, just got GI reduction (p <0.05) in serum total cholesterol (-12.8 mg / dL), LDL cholesterol (-10.47 mg / dL) and triglycerides (-15.00 mg / dL), and increasing concentrations of HDL (+3.63 mg / dl, p <0.01). The activity of GPx and SOD increased in GI (p <0.05), with differences between groups for GPx (+0.08 versus -0.07 U / mg, p <0.001, respectively). Therefore, consumption of 20 g almonds baru associated with prescription normocaloric reduced adiposity, improved lipid profile and increased the activity of antioxidant enzymes in overweight women.O consumo de oleaginosas está associado à redução do risco para doenças cardiovasculares. A amêndoa de baru (Dipteryx alata Vog.) desperta interesse científico por sua composição nutricional. O objetivo desse ensaio clínico controlado e randomizado foi avaliar o efeito do consumo da amêndoa de baru associado à prescrição normocalórica sobre a composição corporal, perfil lipídico e atividade de enzimas antioxidantes em mulheres com excesso de peso. Participaram do estudo 46 mulheres com excesso de peso que receberam prescrição de dieta normocalórica e foram randomizadas em grupo placebo (GP, n= 22; 800 mg de maltodextrina) e em grupo intervenção (GI, n= 24; 20 g de amêndoa de baru). Medidas de adiposidade, pressão arterial, lipídios séricos, parâmetros bioquímicos e atividade enzimática das enzimas catalase, glutationa peroxidase (GPx) e superóxido dismutase (SOD) foram determinados no início e ao final do estudo. A análise estatística foi realizada utilizando o software Stata for Windows (versão 12.0). As comparações das médias e diferenças pré e pós-intervenção entre os grupos foram analisadas pelo teste t de Student. As diferenças pré e pós-intervenção intra-grupos foram analisadas pelo test t para amostras pareadas, considerando como significativo p<0,05. A massa corporal reduziu em GP e GI, no entanto a redução da adiposidade foi observada apenas em GI. A redução da circunferência da cintura foi 1,7 vezes maior em GI, quando comparada ao GP (p=0,01). Quanto ao perfil lipídico, apenas GI obteve redução (p<0,05) nas concentrações séricas de colesterol total (-12,8 mg/dL), LDL (-10,47 mg/dL) e triacilgliceróis (-15,00 mg/dL), e aumento nas concentrações de HDL (+3,63 mg/dL, p<0,01). A atividade das enzimas GPx e SOD aumentaram em GI (p<0,05), com diferença entre os grupos para GPx (+0,08 contra -0,07 U/mg, p<0,001, respectivamente). Portanto, o consumo de 20 g de amêndoa de baru associada à prescrição normocalórica reduziu a adiposidade, melhorou o perfil lipídico e aumentou a atividade de enzimas antioxidantes em mulheres com excesso de peso

Gut Microbiota, Probiotics and Diabetes

Diabetes is a condition of multifactorial origin, involving several molecular mechanisms related to the intestinal microbiota for its development. In type 2 diabetes, receptor activation and recognition by microorganisms from the intestinal lumen may trigger inflammatory responses, inducing the phosphorylation of serine residues in insulin receptor substrate-1, reducing insulin sensitivity. In type 1 diabetes, the lowered expression of adhesion proteins within the intestinal epithelium favours a greater immune response that may result in destruction of pancreatic β cells by CD8+ T-lymphocytes, and increased expression of interleukin-17, related to autoimmunity. Research in animal models and humans has hypothesized whether the administration of probiotics may improve the prognosis of diabetes through modulation of gut microbiota. We have shown in this review that a large body of evidence suggests probiotics reduce the inflammatory response and oxidative stress, as well as increase the expression of adhesion proteins within the intestinal epithelium, reducing intestinal permeability. Such effects increase insulin sensitivity and reduce autoimmune response. However, further investigations are required to clarify whether the administration of probiotics can be efficiently used for the prevention and management of diabetes

Nuts and Human Health Outcomes: A Systematic Review

There has been increasing interest in nuts and their outcome regarding human health. The consumption of nuts is frequently associated with reduction in risk factors for chronic diseases. Although nuts are high calorie foods, several studies have reported beneficial effects after nut consumption, due to fatty acid profiles, vegetable proteins, fibers, vitamins, minerals, carotenoids, and phytosterols with potential antioxidant action. However, the current findings about the benefits of nut consumption on human health have not yet been clearly discussed. This review highlights the effects of nut consumption on the context of human health

Probiotics in Crohn's disease remission: a systematic review

Crohn's disease (CD) is an inflammatory condition that can affect the entire gastrointestinal tract due to an exacerbated and inadequate immune system response. Objective. This study aimed to conduct a systematic review, through clinical trials, about the use of probiotics in humans with CD. Materials and methods. Research was carried out in the PubMed, Scopus and Science Direct databases using the keywords “Crohn's disease” and “probiotics”. We conducted the review by searching clinical trials published from 2000 to December 2019. Results. Of 2,164 articles found, only nine were considered eligible for this review. The studies investigated patients with CD at different stages of the pathology, and in three studies the potential effect of probiotics in the active phase was observed; in two, in the remission phase; and in four, after intestinal surgery. The sample size of the studies ranged from 11 to 165 individuals and the age of the participants between 5 and 71 years. Gram-positive bacteria were used in six clinical interventions and in two studies yeasts were used. As for the significant results obtained with the treatment with probiotics, in one study there was beneficial clinical effects in patients and, in another, there was an improvement in intestinal permeability. Conclusion. Currently, it is not possible to establish a recommendation for probiotic therapy to control CD due to the few clinical trials with significant results. There is a need for more research on clinical intervention with probiotics in CD to clarify the action, define doses and time of use.La enfermedad de Crohn (EC) es una afección inflamatoria que puede afectar todo el tracto gastrointestinal debido a una respuesta del sistema inmunitario exacerbada e inadecuada. Objetivo. Realizar una revisión sistemática, a través de ensayos clínicos, sobre el uso de probióticos en humanos con EC. Materiales y métodos. La investigación se realizó en las bases de datos PubMed, Scopus y Science Direct utilizando las palabras clave “enfermedad de Crohn” y “probióticos”. La revisión se hizo en ensayos clínicos publicados desde 2000 hasta diciembre 2019. Resultados. De 2164 artículos encontrados, solo nueve fueron considerados elegibles. Los estudios investigaron pacientes con EC en diferentes etapas de la patología, y en tres estudios se observó el efecto potencial de los probióticos en la fase activa; en dos, en remisión; y en cuatro, tras cirugía intestinal. El tamaño de la muestra fue entre 11 y 165 individuos y la edad entre 5 y 71 años. Se utilizaron bacterias grampositivas en seis intervenciones clínicas y en dos estudios se utilizaron levaduras. En cuanto a los resultados significativos obtenidos con el tratamiento con probióticos, en un estudio hubo efectos clínicos beneficiosos en los pacientes y, en otro, hubo una mejora en la permeabilidad intestinal. Conclusión. Actualmente, no es posible establecer una recomendación de terapia con probióticos para el control de la EC debido a los pocos ensayos clínicos con resultados significativos. Existe la necesidad de más investigación sobre la intervención clínica con probióticos en EC para aclarar la acción, definir dosis y tiempo de uso

Métodos de análise da composição corporal em adultos obesos

Os métodos de avaliação da composição corporal em obesos têm sido amplamente discutidos, uma vez que nesses indivíduos a avaliação é dificultada devido às limitações dos equipamentos e características dos métodos utilizados. Esta sessão temática tem o objetivo de esclarecer as características, vantagens e limitações dos métodos de avaliação da composição corporal em adultos obesos. A quantificação de gordura corporal e mas-sa livre de gordura, assim como a avaliação da perda de massa muscular e de massa óssea em obesos são temas de grande interesse científico, uma vez que são utilizados para diagnosticar a obesidade osteosarcopênica. A avaliação da composição corporal de obesos pelo modelo de múltiplos compartimentos é padrão-ouro na prática científica. Por outro lado, o método de absorciometria radiológica de feixe duplo é considerado o padrão de referência em pesquisas e na prática clínica. Estudos indicam que a ressonância magnética e a tomografia computadorizada, em alguns casos, são fortemente correlacionadas com a absorciometria radiológica de feixe duplo. Os demais métodos apresentam limitações em avaliar a composição corporal, bem como suas modificações durante a redução ponderal em indivíduos obesos

Baru Almonds Increase the Activity of Glutathione Peroxidase in Overweight and Obese Women: A Randomized, Placebo-Controlled Trial

Background: Obesity-induced inflammation is frequently associated with higher oxidative stress. In vitro and experimental studies have considered baru almonds (Dipteryx alata Vog) as a legume seed with high antioxidant capacity. The aim of this study was to evaluate whether baru almonds are capable of improving the inflammatory and antioxidant status in overweight and obese women. Methods: In a parallel-arm, randomized placebo-controlled trial, 46 overweight and obese women (age: 40 &plusmn; 11 years; body mass index: 33.3 &plusmn; 4.3) were randomly assigned to receive advice to follow a normocaloric and isoenergetic diet with placebo (PLA, n = 22) or similar advice plus 20 g baru almonds (BARU, n = 24) for 8 wk. Malondialdehyde (MDA), adiponectin, tumor necrosis factor-&alpha;, interleukin-6, interleukin-10, antioxidant enzymes activities (catalase&mdash;CAT; glutathione peroxidase&mdash;GPx; superoxide dismutase&mdash;SOD), and minerals were analyzed in plasma samples. Results: At baseline, groups were similar regarding the body composition, oxidative, and inflammatory parameters. The BARU group increased the activity of GPx (+0.08 U/mg, 95%CI + 0.05 to +0.12 vs. &minus;0.07, 95%CI &minus;0.12 to &minus;0.03, p &lt; 0.01) and plasma copper concentration (p = 0.037) when compared to the PLA group. No differences were observed between groups in CAT and SOD activity or MDA and cytokines concentrations. Conclusions: Baru almond supplementation increased the GPx activity in overweight and obese women

Este estudo descreve alguns resultados do sistema de monitoramento de fatores de risco para doenças crônicas por entrevistas telefônicas no Município de Goiânia, Goiás, Brasil, 2005. Foi estudada amostra probabilística (n = 2.002) da população adulta servida por linhas telefônicas residenciais fixas. Foram analisadas variáveis comportamentais (consumo alimentar, atividade física, tabagismo e consumo de bebida alcoólica), peso e altura referidos e referência a diagnóstico médico de doenças crônicas. Foram calculadas estimativas de prevalência e valores de qui-quadrado. Observou-se baixo consumo de frutas e hortaliças (47,1%), alta freqüência de inatividade física ocupacional (86,6%), no deslocamento para o trabalho (92,6%) e lazer (61,9%), consumo excessivo de bebidas alcoólicas (23,2%), excesso de peso (36,5%), obesidade (10,6%), hipertensão arterial (22,4%), dislipidemias (18,4%) e diabetes (4,4%). A maioria dos fatores de risco apresentou associação inversa com escolaridade e direta com idade, com diferenças significativas entre sexos (p < 0,05). Observou-se alta prevalência dos fatores de risco de doenças crônicas não transmissíveis e de auto-referidas. Aspectos positivos do sistema: baixo custo operacional, possibilidade de monitorar a carga e a tendência das doenças crônicas não transmissíveis no nível local.<br>This study describes results from a surveillance system for risk factors for chronic non-communicable diseases in 2005 in the city of Goiânia, Goiás State, Brazil. A probabilistic sample (n = 2,002) of the adult population living in households with landline telephones was studied by phone interviews. Factors investigated were: food consumption, physical activity, smoking, alcohol intake, self-reported weight and height, and self-reported medical diagnosis of chronic non-communicable diseases. Prevalence and c² values were calculated. The data showed: low consumption (< 5 days/week) of fruits and vegetables (47.1%), high rate of physical inactivity at work (86.6%), in commuting (92.6%), and during leisure time (61.9%), high alcohol consumption (36.5%), and high rates of obesity (10.6%), hypertension (22.4%), dyslipidemia (18.4%), and diabetes (4.4%). Most of the factors were inversely related to schooling and directly related to age (p < 0.05). High prevalence of risk factors for chronic non-communicable diseases was reported. The advantages of this system were: low operational cost and the ability to monitor trends in chronic non-communicable diseases at the local level
