Olive oil intake and CVD risk

Higher olive oil intake tracked lower major CVD events and cardiovascular death in PREDIMED participants.

Olive oil intake and risk of cardiovascular disease and mortality in the PREDIMED Study

Guasch-Ferré M, Hu FB, Martínez-González MA, et al. · BMC medicine · 2014

What they did

In 7,216 PREDIMED participants, baseline olive oil intake was related to incident major CVD events and mortality over median 4.8 years.

Each additional 10 g/day olive oil associated with 13% lower major CVD events (HR 0.87) and 16% lower CV mortality (HR 0.84).

The limits

Observational intake contrasts within a trial cohort are not equivalent to randomising olive oil alone; residual confounding possible.

Key terms

Olive oil: Key Mediterranean fat source analysed by intake.
Major CVD events: Composite hard cardiovascular endpoints.
Hazard ratio: Relative risk per intake contrast.
PREDIMED: Mediterranean diet randomised trial cohort used here observationally.
EVOO: Extra-virgin olive oil.
Tablespoon (~10 g): Intake unit used in models.
