MICROBIOTA INTESTINAL: ROL EN OBESIDAD
Farías N,María Magdalena; Silva B,Catalina; Rozowski N,Jaime;
Revista chilena de nutrición , 2011, DOI: 10.4067/S0717-75182011000200013
Abstract: obesity and diabetes have become major public health issues in our country. the increasing prevalence of obesity and its association with diabetes might not only be explained by genetic contribution, nutritional habits or decreased physical activity. in addition, recent studies have focused on the intestinal microbiota as environmental factors that increase energy yield from diet, regulate synthesis of gut hormones, peripheral metabolism and systemic inflammatory tone. obesity is associated with substantial changes in composition of gut microbiota, suggesting that the development of obesity on some people may be due to these changes. existing evidence warrants further investigation of the microbial ecology oh the human gut and points to modification of the gut microbiota, by functional foods or antibiotics, as one means to treat and prevent obesity.
MICROBIOTA INTESTINAL: ROL EN OBESIDAD GUT MICROBIOTA: ROLE IN OBESITY

Abstract: La obesidad es una patología metabólica altamente prevalente en nuestro país y constituye un gran problema de salud pública. Según lo han demostrado recientes estudios, la obesidad y su asociación con la diabetes no son únicamente el resultado de la contribución genética, los hábitos alimentarios o la falta de actividad física, sino que también se ha comprobado que la microbiota intestinal constituye un factor ambiental determinante en el desarrollo de estas patologías. Este vínculo estaría relacionado con una modulación, por parte de la mi-crobiota, en la extracción energética de los alimentos, la secreción de hormonas intestinales, el metabolismo a nivel periférico y el tono inflamatorio sistémico. Lo anterior se refleja en las diferencias significativas en cuanto a la composición de la microbiota intestinal que se observa en quienes padecen obesidad. En relación a la evidencia actual, resulta importante investigar los efectos en la modificación de la microbiota intestinal, mediante el uso alimentos funcionales y antibióticos, a fin de aplicar tanto tratamientos terapéuticos como preventivos contra el desarrollo de la obesidad.

Abstract: it has been observed that foods with similar amount of starch can genérate different glycemic responses. in the present paper we review the one factor that probably determines these differences: the physical state of starch infood. the literature support the idea that the physical state (called microstructure) of starch is a very important factor because determine the rate and the total amount of glucose that will be released (in the digestión process) for absorption and metabolic use. many studies relating the microstructure and glycemic response, and its physiological effects, are still needed to make new carbohydrate foods with specific nutritional requirements

Abstract: Se ha observado que alimentos que contienen almidón en cantidades similares pueden generar respuestas glicémicas diferentes. En este trabajo se realizó una revisión bibliográfica tendiente a estudiar uno de los factores que modelaría estas diferencias: el estado físico del almidón contenido en el alimento. Los resultados expuestos indican que el estado físico (que llamaremos microestructura) del almidón es uno de los factores principales a considerar, ya que determinaría cómo y qué fracción del total será digerida, lo cual a su vez determina cómo y cuánto será absorbido para su uso metabólico. Estudios tendientes a una mejor cuantificación, tanto de la microestructura como de la respuesta glicémica y efectos fisiológicos, parecen ser necesarios si se tiene como objetivo el poder dise ar alimentos que cumplan con requerimientos nutricionales específicos It has been observed that foods with similar amount of starch can genérate different glycemic responses.

Abstract: the metabolic syndrome (ms), also known as ?syndrome x? or ?insulin resistance syndrome?, is defined by the simultaneous presence, in an individual, of several risk factors which induce a higher risk of contracting diabetes mellitus and cardiovascular disease. their common link is, probably, insulin resistance (ir) and/or hyperinsulinism. it is considered that the ms is caused by genetic and environmental factors including an imbalanced diet. a food consumption pattern typical of the mediterranean countries has been proposed as the reason for the low cardiovascular morbidity and mortality and the longer life expectancy in those countries. the present review discusses the characteristics of the mediterranean diet and its health benefits related to the ms

Abstract: the aim of this study was to determine food and nutrient intake of underweight pregnant women of the south-east metropolitan region. we studied 411 pregnant women attending health control clinics in years 2002 to 2004. dietary intake was determined by a 24-hour recall taken at home in week 20 and 35 by trained nutritionists. nutrient intake was analyzed using the software food processor 7.9, and compared with the recommended servings from the ministry of health. baseline characteristics (mean ± sd): age 23.8 ± 5.4 years, weight 49.3 ± 4.7 kg, height 156.9 ± 5.9 cm, gestational age 11.5 ± 3,7 weeks. compared with the recommendations the intake of energy and macronutrients was adequate while the intake of vitamin a, c, e and b6, calcium and zinc were 75% of the recommendations. the intake of omega-3 fatty acids averaged 61 ± 50 and 71 ± 24 mg/day in week 20 and 35, respectively, a sixth of the nih recommendation. deficient intakes were foundfor dairy products, fruits, vegetables and meats, however there was a higher intake of cereals. conclusions: the nutrient intake ofpregnant women in this group is insufficient in several micronutrients, resulting from inadequate food intake; this should be corrected by improving the quality of their diet or other measures such as supplementation with these micronutrients.
ROL DE LA DIETA MEDITERRáNEA EN LA PREVALENCIA DEL SINDROME METABóLICO MEDITERRANEAN DIET AND ITS ROLE IN THE PREVALENCE OF METABOLIC SYNDROME

Abstract: El Síndrome Metabólico (SM), conocido también como Síndrome X o Síndrome de Insulino Resistencia (IR), se define por la presencia, en un individuo, de un conjunto de factores asociados e interrelacionados entre si que inducen un mayor riesgo de diabetes mellitus (DM) y enfermedad cardiovascular (EC), y cuyo nexo común es posiblemente la resistencia a la insulina (RI) y/ o el hiperinsulinismo. Se ha considerado que el SM obedece a causas genéticas y ambientales, destacando en estas últimas, una dieta desequilibrada, condicionante de muchos de los atributos del SM. Por otro lado, se ha sugerido que los hábitos alimentarios de los países Mediterráneos son los principales determinantes de la baja prevalencia de morbi-mortalidad cardiovascular y general, e incremento de la expectativa de vida de estas poblaciones. Con el objetivo de reforzar las estrategias de prevención cardiovascular en el SM, se ha postulado que pudieran beneficiarse adicionalmente al adoptar una dieta tipo mediterránea. Para ello se requiere realizar simples modificaciones en su estilo de vida, que se traducirán en un incremento substancial de la expectativa de vida. En esta revisión se resume la evidencia científica con respecto al posible efecto de la dieta mediterránea en el desarrollo y control del SM The Metabolic Syndrome (MS), also known as Syndrome X or Insulin Resistance Syndrome , is defined by the simultaneous presence, in an individual, of several risk factors which induce a higher risk of contracting diabetes mellitus and cardiovascular disease.

Abstract: Existe escasa información en nuestro país sobre la alimentación de diferentes grupos de la población. El objetivo del estudio es conocer la dieta consumida por escolares que efectúan actividad física regularmente y determinar su composición corporal. Se evaluaron 105 escolares entre 11 y 14 a os pertenecientes a dos clubes deportivos, quienes en promedio realizan actividad física programada 8 horas por semana. La evaluación antropométrica incluyó peso, estatura, pliegue tricipital y subescapular, además de un registro alimentario de 24 horas. Se evaluó el nivel socioeconómico mediante la encuesta ESOMAR. Como era de esperar el peso y la talla aumentaron progresivamente con la edad. El porcentaje de grasa corporal aumentó entre 11 y 13 a os de edad para luego descender a los 14 a os. Un 86% presentó un estado nutricional normal y 14% sobrepeso. No se observó obesidad en este grupo de ni os. Tanto la ingesta energética como los macronutrientes fueron suficientes en todos los grupos, encontrándose déficit solo para calcio y potasio que se asocia a baja ingesta de lácteos, frutas y verduras. En conclusión, este grupo presenta patrones similares de consumo alimentario que escolares de la misma edad, sin embargo presentan mejor estado nutricional, probablemente debido al mayor nivel actividad física.
