Prevention With Oleanolic Acid of Insulin Resistance (PREOLIA)
September 10, 2021 updated by: Emilio Gonzalez Jimenez, Universidad de Granada
Prevention With Oleanolic Acid of Insulin Resistance and Metabolic Syndrome in Adolescents
Oleanolic acid (OA), a triterpene that is highly present in olive leaves, has been proposed as component of functional foods in the prevention of metabolic syndrome due to its anti-inflammatory activity.
In this research project we will study the presence of OA in postprandial TRL in healthy adolescents and in normal weight.
Moreover, THP-1 macrophages will be incubated with LPS for 48h after pretreatment with OA at different concentrations.
Also, TRL will be isolated from healthy adolescents before and 2 and 5h postprandially after the intake of a meal containing the functional olive oil or common olive oil and incubated with THP-1 macrophages.

Intervention / Treatment |
---|---|
Experimental: OA-enriched functional olive oil
|
Eleven adolescents will consume OA-enriched functional olive oil.
After eating the olive oil, aliquots of cubital blood will be drawn at 2 and 5 hours of the postprandial period.
During that time, free access to water intake will be allowed.

Active Comparator: Olive oil not enriched in OA
|
Eleven adolescents will consume olive oil.
After eating the olive oil, aliquots of cubital blood will be drawn at 2 and 5 hours of the postprandial period.
During that time, free access to water intake will be allowed.
