Effect of Polyphenol Intake and Adherence to the Mediterranean Diet on Oxidative Stress During Pregnancy

Обзор

This study is a randomized controlled clinical trial designed to evaluate the effect of a polyphenol-rich dietary intervention during pregnancy on endothelial function, oxidative stress biomarkers, and maternal and neonatal outcomes. Pregnancy is associated with metabolic and vascular adaptations, and complications such as gestational diabetes and hypertensive disorders are linked to endothelial dysfunction and increased oxidative stress. Dietary factors, particularly adherence to the Mediterranean diet and intake of polyphenol-rich foods, may play a protective role. Pregnant women will be randomly assigned to either an intervention group or a control group. The intervention consists of daily consumption of 10 g of natural non-alkalized cocoa and structured dietary counseling aimed at achieving at least five daily servings of fruits and vegetables, alongside general Mediterranean diet recommendations. The intervention will last 12 weeks, from early to mid-pregnancy. Biomarkers of endothelial function and oxidative stress will be measured at different time points, along with clinical maternal outcomes (including gestational diabetes and hypertensive disorders) and neonatal outcomes. The aim is to determine whether this dietary intervention improves endothelial function, reduces oxidative stress, and contributes to better pregnancy outcomes.
