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.).

Detailed description

In a randomized, acute, single-blinded and cross-over study, participated 21 volunteers with high cardiometabolic risk, aged 30-65, were randomized and divided into two groups. The first group consumed a meal of mashed potatoes with added refined olive oil, rich in fat and carbohydrates (300g, control meal), while the second group consumed mashed potatoes with added olive oil, enhanced with 10% w/w orange peel extract (functional meal). After a one-week washout period, the volunteers were crossed over and consumed the meals in reverse. Blood samples were withdrawn in a fasting state, 30, 90 and 180 min after meal consumption. Plasma Total Antioxidant Capacity (FRAP), serum lipid levels \[Total, High-Density Lipoprotein (HDL-) and Low-Density Lipoprotein (LDL-) cholesterol and triglycerides\], glucose and uric acid were determined at each time point using a biochemical analyzer (Roche Cobas c111).
