High baseline consumption of extra-virgin olive oil (EVOO) is associated with a significantly reduced risk of major cardiovascular events (myocardial infarction, stroke, or cardiovascular death) in individuals at high cardiovascular risk.
If you are at high risk for heart disease, incorporating extra-virgin olive oil into your daily diet (aiming for roughly 3-4 tablespoons or more per day if possible, as seen in the highest benefit group) is associated with a significantly lower risk of heart attacks and strokes. Ensure you are using extra-virgin quality to get the protective polyphenols, as refined olive oil did not show the same benefit.
Participants in the highest energy-adjusted tertile of baseline total olive oil and extra-virgin olive oil consumption had 35% (HR: 0.65; 95% CI: 0.47 to 0.89) and 39% (HR: 0.61; 95% CI: 0.44 to 0.85) cardiovascular disease risk reduction, respectively, compared to the reference.
Why this rating
Based on a large, multicenter, randomized controlled trial (PREDIMED) with rigorous adjudication, though this specific analysis is observational within the trial framework.
