Scope The main findings of the “Virgin Olive Oil and HDL Functionality” (VOHF) study and other related studies on the effect of phenol‐enriched virgin olive oil (VOO) supplementation on cardiovascular disease are integrated in the present work. Methods and results VOHF assessed whether VOOs, enriched with their own phenolic compounds (FVOO) or with those from thyme (FVOOT), improve quantity and functionality of HDL. In this randomized, double‐blind, crossover, and controlled trial, 33 hypercholesterolemic subjects received a control VOO (80 mg kg −1 ), FVOO (500 mg kg −1 ), and FVOOT (500 mg kg −1 ; 1:1) for 3 weeks. Both functional VOOs promoted cardioprotective changes, modulating HDL proteome, increasing fat‐soluble antioxidants, improving HDL subclasses distribution, reducing the lipoprotein insulin resistance index, increasing endogenous antioxidant enzymes, protecting DNA from oxidation, ameliorating endothelial function, and increasing fecal microbial metabolic activity. Additional cardioprotective benefits were observed according to phenol source and content in the phenol‐enriched VOOs. These insights support the beneficial effects of OO and PC from different sources. Conclusion Novel therapeutic strategies should increase HDL‐cholesterol levels and enhance HDL functionality. The tailoring of phenol‐enriched VOOs is an interesting and useful strategy for enhancing the functional quality of HDL, and thus, it can be used as a complementary tool for the management of hypercholesterolemic individuals.
