Esos componentes son los fenoles, que en el laboratorio han demostrado poseer efectos antioxidantes, antiinflamatorios y preventivos de la formación de trombos. Según el Dr. Pérez Jiménez, la ingesta elevada de alimentos que contienen fenoles puede mejorar la salud cardiovascular y proteger el corazón.
Los investigadores compararon los efectos derivados del consumo de aceite de oliva rico en fenoles frente a un aceite de oliva del que se habían extraído la mayoría de estas sustancias en un grupo de 21 voluntarios que presentaban colesterol elevado.
Midieron la capacidad de los vasos para responder a cambios rápidos en el flujo sanguíneo tras haber consumido alimentos ricos en grasa que contenían un tipo u otro de aceite de oliva.
La función de los vasos mejoró en aquellos voluntarios que consumieron el aceite de oliva rico en fenoles durante las 4 primeas horas. También observaron en este grupo mayores niveles de óxido nítrico y menores niveles de estrés oxidativo.
