NCT05771571

Brief Summary

The purpose of this study was the investigation of the hypothesis that the enhancement of a refined olive oil with orange peel extract, may improve the postprandial lipidemic, glycemic profile and blood oxidative status, of volunteers with high cardiometabolic risk, due to increased content of bioactive compounds (polyphenols, carotenoids etc.).

CROSSOVER
Model Details: Participants were randomly divided into control and interventional group. In the first study period, the control group consumed the meal with the refined olive oil and the interventional group received the meal with the novel, functional olive oil, enhanced with 10% w/w orange peel extract. After a washout week participants were crossed over and consumed the meals in reverse.
