La lute\u00edna forma parte de una clase de compuestos antioxidantes llamados carotenoides, y es el principal carotenoide encontrado en el \u00e1rea central de la retina humana\u00a0\u00a0(conocida como m\u00e1cula), de tal forma que, aparentemente, se relaciona con la protecci\u00f3n contra la degeneraci\u00f3n macular relacionada con la edad, causa importante de ceguera en adultos mayores.<\/p>\n

Actualmente, se piensa que la lute\u00edna funciona de dos maneras:<\/p>\n

    \n
  1. Como filtro para la luz azul de alta energ\u00eda y la luz ultravioleta<\/li>\n
  2. Como antioxidante que sofoca a los radicales libres inducidos por la luz y especies reactivas del ox\u00edgeno<\/li>\n<\/ol>\n

    Aunque no se conoce bien el papel desempe\u00f1ado por la lute\u00edna en la fisiolog\u00eda del ojo, los v\u00ednculos entre ella y la salud ocular son tan fuertes, que diversas organizaciones de salud nacionales y regionales han recomendado que se incremente su ingesta en la dieta.<\/p>\n

    La lute\u00edna se encuentra en muchas fuentes alimenticias, y la principal son los vegetales de hoja verde, pero tambi\u00e9n se encuentra en menor cantidad en otras frutas y verduras coloridas, como, br\u00f3coli, pimiento naranja, elote, guisantes, caqui y mandarina.<\/p>\n

    Desafortunadamente, la mayor\u00eda de las encuestas sobre la dieta indican que pocas personas consumen cantidades \u00f3ptimas de alimentos ricos en lute\u00edna.<\/p>\n","protected":false},"excerpt":{"rendered":"
