What this trial studies

This study investigates the potential benefits of Extra Virgin Olive Oil from early harvested olives in reducing the risk of preeclampsia among high-risk pregnant women. The intervention involves a daily intake of 42 ml of this olive oil, which is rich in antioxidants and may improve vascular health and reduce oxidative stress. The primary objective is to evaluate the incidence of preeclampsia and its related markers during pregnancy in a randomized, parallel-assignment dietary trial involving 156 participants aged 18 to 45. The study aims to assess the impact of this dietary intervention on pregnancy outcomes, including gestational diabetes mellitus.

Why it matters

Potential benefit: If successful, this intervention could significantly lower the risk of preeclampsia and improve pregnancy outcomes for high-risk women.

How similar studies have gone: While dietary interventions for preeclampsia risk are being explored, this specific approach using Extra Virgin Olive Oil is novel and has not been extensively tested in prior studies.
