Según estos resultados, los adultos que consumen 25 mililitros diarios -equivalentes a dos cucharadas- de aceite de oliva virgen muestran una menor oxidación del colesterol LDL y una mayor concentración de antioxidantes en sangre. Algunas investigaciones han asociado dicha oxidación con un mayor endurecimiento de las arterias, lo cual incrementa el riesgo cardíaco.
El hallazgo ayuda a explicar los beneficios saludables de la dieta mediterránea. Los autores también subrayan que el aceite de oliva virgen contiene altos niveles de antioxidantes, en particular fenoles y vitamina E.
