Olive oil polyphenols are know for beneficial properties that reduce cardiovascular risk factors. Consumption is a cornerstone of the Mediterranean diet for its ability to produce health high-density lipoprotein profiles (HDL). However, data on polyphenol effects of HDL quality are scarce. This study assessed whether polyphenol-rich olive oil consumption could enhance the HDL main function, its cholesterol efflux capacity, and some of its quality-related properties, such HDL polyphenol content, size, and composition. The results once again show extra-virgin olive oil’s capacity for improved health. This article also give you some healthy advice from Today’s Practitioner editor as to how to tell your patients to buy good quality extra-virgin olive oil.
