High consumption of total olive oil is associated with a reduced risk of cardiovascular mortality, but not cancer or all-cause mortality.
Eating more olive oil (especially extra-virgin) can significantly lower your risk of dying from heart-related causes. However, do not expect it to prevent cancer or extend your overall lifespan beyond cardiovascular benefits. It is a specific, powerful tool for heart health, not a general 'life extension' pill.
GoodQualifiesHIGH confidence
Higher baseline total olive oil consumption was associated with 48% (HR: 0.52; 95% CI: 0.29 to 0.93) reduced risk of cardiovascular mortality. No significant associations were found for cancer and all-cause mortality.
Why this rating
Same high-quality observational analysis within PREDIMED.
