Impact of Extra Virgin Olive Oil Oleocanthal Content on Platelet Reactivity

• Status: Completed
• Trial end date: 2015-09-01
• Target enrollment: 0
• Participant gender: Male

Summary

Data from limited dietary intervention trials suggest that the cardiovascular health benefit of extra virgin olive oil (EVOO) may increase with phenolic content. However, while EVOOs contain an array of bioactive compounds, little information exists regarding the physiological effects of specific chemical species. Among the EVOO-derived phenolics with demonstrated anti-inflammatory effects in animal and in vitro models is oleocanthal, an inhibitor of cyclooxygenase (COX). The current study compared the impact of acute intake (40 mL) of EVOO on platelet reactivity in healthy adult males (n=9). The volunteers were randomly assigned to consume three EVOOs in a double-blind controlled trial. The EVOO were characterized and chosen for equivalency in their total phenolic content and fatty acid profiles, but differing in their oleocanthal to oleacein ratio.
