title: Impact of olive oil-rich diet on serum omentin and adiponectin levels: a randomized cross-over clinical trial among overweight women.
abstract: This study aimed to investigate the effect of olive oil-rich diet on omentin and adiponectin concentrations. This cross-over randomized trial included 17 overweight women. Participants were assigned to consume either a usual (16% saturated fatty acids [SFA] and 8% monounsaturated fatty acid [MUFA]) or an olive oil-rich diet (16% MUFA and 8% SFA) for 6 weeks crossing over after a 2-week washout period. There was no significant difference in the changes of omentin between two dietary interventions. However, in the adjusted model for polyunsaturated fatty acids and fat mass, usual diet tended to decrease omentin levels whilst olive oil-rich diet tended to increase (-56.1 ± 32.0 versus 40.6 ± 32.0 ng/mL; p = .056). Adiponectin levels increased during two periods, but changes were greater during olive oil-rich diet with a trend toward significance (4.8 ± 3.0 versus 13.4 ± 3.0 μg/mL; p = .06). Consumption of olive oil-rich diet tended to increase omentin and adiponectin in comparison with the usual diet.
