Abstract Extra-virgin olive oil (EVOO) possesses beneficial health effects due to its antioxidant activity. In a controlled before-and-after supplementation trial (45 healthy adults), we examined the effects of daily consumption (30 days (d), 50 mL/d) of EVOO rich in phenolic compounds, antioxidant activity and antioxidant enzymes (catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPX)). Participants completed for 30 d a 24-h dietary record. Anthropometric characteristics… Expand
Evidence to Support the Anti-Cancer Effect of Olive Leaf Extract and Future Directions
TLDR
This review aims to amalgamate the current literature regarding bioavailability and mechanisms involved in the potential anti-cancer action of olive leaf polyphenols. Expand
Phenolic content of extra virgin olive oil is essential to restore endothelial dysfunction but not to prevent vascular inflammation in atherosclerotic lesions of Apo E deficient mice
Abstract Extra Virgin Olive Oil (EVOO) contains monounsaturated fatty acids and multiple minor components with biological properties and health benefits. We evaluate whether a diet supplemented onExpand
Antioxidative Effects of Olive Polyphenols Compared to Vitamin E in Piglets Fed a Diet Rich in N-3 PUFA
TLDR
Only minor positive effects of dietary OLE on the oxidative stress parameters were observed and OLE did not show concentration dependence, so OLE could be used as an effective feed additive for beneficial effects on intestinal health and meat quality, among others. Expand
Effects of virgin olive oil phenolic compounds on health: solid evidence or just another fiasco?
TLDR
RCT in extensive and diverse population groups, with different disorders and phenolic doses adjusted to usual VOO consumptions are necessary to achieve high quality scientific evidence before nutritional recommendations can be given to the general public. Expand
Effects of virgin olive oil phenolic compounds on health: solid evidence or just another fiasco?
Current research suggests that virgin olive oil (VOO) phenolics are potent preventive and therapeutic agents against metabolic diseases associated with inflammation and oxidative stress.Expand
Effect of Mediterranean Diet Enriched in High Quality Extra Virgin Olive Oil on Oxidative Stress, Inflammation and Gut Microbiota in Obese and Normal Weight Adult Subjects
TLDR
The results indicate that MD rich in HQ-EVOO induces an increase of LAB in GM and could have a potential role in the prevention of inflammation. Expand
A review of the evolution in the research of antioxidants in olives and olive oil during the last four decades
TLDR
Olives and olive oil antioxidants are not only absorbed by the body, but can also attach to the lining of the digestive tract, contributing to the health impact afforded by these products. Expand

An extra-virgin olive oil rich in polyphenolic compounds has antioxidant effects in OF1 mice.
TLDR
Protection by extra-virgin OO against oxidative stress occurs primarily through a direct antioxidant effect as well as through an indirect mechanism that involves greater expression and activity of certain enzymes with antioxidant activities. Expand
Olive oils high in phenolic compounds modulate oxidative/antioxidative status in men.
TLDR
The olive oil phenolic content modulated the oxidative/antioxidative status of healthy men who consumed a very low-antioxidant diet. Expand
Daily consumption of a high-phenol extra-virgin olive oil reduces oxidative DNA damage in postmenopausal women.
TLDR
Urinary excretion of hydroxytyrosol and its metabolite homovanillyl alcohol were significantly increased in subjects consuming high-EVOO, despite the small sample size, the present study showed a reduction of DNA damage by consumption of an EVOO rich in phenols, particularly hydroxyTYrosol. Expand
Effects of differing phenolic content in dietary olive oils on lipids and LDL oxidation
TLDR
The hypothesis that virgin olive oil consumption could provide benefits in the prevention of oxidative processes is supported, as dose-dependent changes in oxidative stress markers, and phenolic compounds in urine, were observed with the phenolic content of the olive oil administered. Expand
The Effect of Polyphenols in Olive Oil on Heart Disease Risk Factors
TLDR
The EUROLIVE Study aims to assess the effect of sustained daily doses of olive oil, as a function of its phenolic content, on the oxidative damage to lipid and LDL cholesterol levels and the lipid profile as cardiovascular risk factors in healthy men. Expand
The effect of green tea in oxidative stress.
TLDR
The data suggest for green tea drinking a beneficial effect, by reducing the development or the enhancement of oxidative stress and, therefore, protecting the individual for oxidative stress diseases. Expand
Extra virgin olive oil biophenols inhibit cell-mediated oxidation of LDL by increasing the mRNA transcription of glutathione-related enzymes.
TLDR
The mechanisms underlying the protective effect exerted by extra virgin olive oil biophenols, namely, protocatechuic acid and oleuropein, on LDL oxidation mediated by murine J774 A.1 macrophage-like cells are investigated and the activation of mRNA transcription of GSH-related enzymes represents an important mechanism in phenolic antioxidant action.

Administration of minor polar compound-enriched extra virgin olive oil decreases platelet aggregation and the plasma concentration of reduced homocysteine in rats.
TLDR
Results show that MPC in EVOO inhibit platelet aggregation and reduce the plasma rHcy concentration, effects that may be associated with cardiovascular protection. Expand
Antioxidant effect of two virgin olive oils depends on the concentration and composition of minor polar compounds
In vitro studies show that some individual minor polar phenolic compounds (MPC) present in virgin olive oil prevent oxidation of human low-density lipoproteins (LDL), but few data are available onExpand

TLDR
A significant role of olive oil polyphenols in the down‐regulation of proatherogenic genes in the context of a traditional Mediterranean diet is indicated and the benefits associated with a TMD and olive oilpolyphenol consumption on cardiovascular risk can be mediated through nutrigenomic effects.
