ROL DE LA DIETA MEDITERRáNEA EN LA PREVALENCIA DEL SINDROME METABóLICO
Valenzuela B,Andrea; Arteaga Ll,Antonio; Rozowski N,Jaime;
Revista chilena de nutrición , 2007, DOI: 10.4067/S0717-75182007000300003
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
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: introduction: it has been described in the literature that dietary cholesterol produces only slight changes in serum cholesterol in healthy individuals. nevertheless, several studies have shown a marked heterogeneity in the response to a variation of cholesterol in the diet. one of the factors involved in this response is the apo e genotype, also singled as a risk factor for cardiovascular disease. there are no studies in chile that evaluate the response to dietary cholesterol in individuals and its relationship to the apo e genotype. objective: to evaluate the response to a cholesterol load in individuals and relate it to their apo e genotype. materials and methods: a prospective randomized and cross-over study was carried out in 36 male volunteers either normolipemics or isolated hypercholesterolemic aged 25-55 years old, who were given one egg/day for 4 weeks in addition to their normal diet. total, ldl, and hdl cholesterol were measured before and after the intervention, as well as apo b concentration and apo e genotype. results: apo e genotype was 79% e3/3 and 16% e 4/3 in this population. the addition of one egg to their normal diet did not change significantly any of the variables studied. conclusions: normocholesterolemic or hypercholesterolemic individuals did not respond to a load of cholesterol given in the form of one egg/day. the implications for population recommendations are discussed

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
RELACIóN ENTRE LA RESPUESTA GLICéMICA DEL ALMIDóN Y SU ESTADO MICROESTRUCTURAL RELATIONSHIP BETWEEN GLYCEMIC RESPONSE OF STARCH AND ITS MICROSTRUCTURAL STATE

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: 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.

Abstract: El objetivo del estudio es conocer la ingesta de nutrientes y alimentos de las embarazadas bajo peso de la Región Metropolitana Sur-Oriente. Se estudiaron 411 embarazadas que asistían a control de salud durante los a os 2002 al 2004. Se aplicó una encuesta por recordatorio de 24 horas domiciliarias en la semana 20 y 35 por Nutricionistas. Las dietas fueron analizadas utilizando el software Food Processor 7,9, posteriormente se comparó el consumo con las porciones recomendadas por el Ministerio de Salud. Características basales (promedio y D.S.): edad, 23,8 ± 5,4 a os; peso, 49,3 ± 4,7 kg; talla, 156,9 ± 5,9 cm; edad gestational, 11,5 ± 3,7 semanas. Al comparar la ingesta con las recomendaciones se encontró un consumo adecuado de energía y macronutrientes, se encontraron valores menores del 75% de la ingesta recomendada para vitamina A, C, E y B6, calcio y zinc. La ingesta de ácidos grasos omega-3 fue en promedio de 61 ± 50 y 71 ± 24 mg/día en la semana 20 y 35, un sexto de la recomendación NIH. Al comparar la ingesta de alimentos con las recomendaciones, se encontraron ingestas deficientes para, lácteos, frutas, verduras y carnes, por el contrario se encontró una ingesta superior de cereales. Conclusiones: La ingesta de nutrientes en este grupo de embarazadas es insuficiente en varios micronutrientes, producto del inadecuado consumo de alimentos, ello debiera ser corregido, mediante la mejoría de la calidad de su alimentación u otras acciones tales como la suplementación de estos micronutrientes en alimentos de consumo frecuente.
