description Hypertension is one of the most important risk factors associated with the development of cardiovascular diseases. Numerous studies have revealed that a diet enriched in olive oil can have a beneficial effect on blood pressure. This systematic review includes the effects of olive oil on blood pressure in individuals without previous cardiovascular events. Liquid oil shows a decrease in blood pressure, while capsules have not produced any effect. Diastolic blood pressure decreased after the consumption of olive oil, -0.73 mm Hg, 95% CI (-1.07, -0.40); p < 0.001, I2 = 86.9%, with high heterogeneity among the included studies. This reduction was mainly due to extra virgin olive oil (EVOO) from 10 ml to 50 ml/day: -1.44 mm Hg, 95% CI (-1.89, -1.00); p < 0.001. Regarding systolic blood pressure the observed decrease is not statistically significant. Further studies on the consumption of EVOO are needed to confirm these results.
