Las grasas en la alimentación

Authors: Farran, Andreu;

Las grasas en la alimentación

Abstract

Las grasas constituyen un nutriente esencial en la alimentación humana, debido a su papel como fuente de energía, elemento estructural y regulador. Su digestión es un proceso complejo, en el cual participan diferentes lipasas y sustancias emulsionantes contenidas en la bilis. La absorción se produce a través de difusión pasiva micelar que puede ser facilitada por proteínas de la membrana apical del enterocito. El transporte de sustancias grasas se realiza a través de diferentes lipoproteínas plasmáticas (principalmente: quilomicrones, VLDL, LDL, HDL). Las principales fuentes de grasas en alimentación humana son: los aceites y grasas vegetales, y las grasas animales. Existen, sin embargo, algunos alimentos cuyo contenido alto en grasa no es evidente para el consumidor. Las recomendaciones de ingesta en población infantil se centran en controlar la ingesta de grasas, limitar la ingesta de saturados y ácidos grasos trans, asegurando un mínimo de ingesta de ácidos grasos poliinsaturados
