Abstract

BACKGROUND & AIMS: The specific association of olive oil consumption with coronary heart disease (CHD) or stroke has not been totally established.

OBJECTIVE: to examine whether olive oil consumption is associated with subclinical atherosclerosis, the risk of total cardiovascular disease (CVD), CHD, and stroke.

METHODS: Three cohorts were included: AWHS (2318 men), SUN Project (18,266 men and women), and EPIC-Spain (39,393 men and women). Olive oil consumption was measured at baseline using validated questionnaires.

RESULTS: In the AWHS, 747 participants had a positive coronary artery calcium score (CACS>0), and the OR (95% CI) was 0.89 (0.72, 1.10) in those with virgin olive oil consumption ≥30 g/day (v. <10 g/day). In the SUN Project (follow-up 10.8 years) 261 total CVD cases occurred, and the HR was 0.57 (0.34, 0.96) for consumptions ≥30 g/day (v. <10 g/day). In the EPIC-Spain (follow-up 22.8 years) 1300 CHD cases and 938 stroke cases occurred; the HRs for stroke according, 0 to <10 (ref), 10 to <20, 20 to <30, and ≥30 g/day of olive oil consumption, were 0.84 (0.70, 1.02), 0.80 (0.66, 0.96), 0.89 (0.74, 1.07). A weaker association was observed for CHD. The association was stronger among those consuming virgin olive oil, instead of common (refined).

CONCLUSIONS: Olive oil is associated with lower risk of CVD and stroke. The maximum benefit could be obtained with a consumption between 20 and 30 g/day. The association could be stronger for virgin olive oil and might operate from the early stages of the disease.
