Nutritional Intervention With Table Olives in Healthy Volunteers

Table Olives Nutritional Intervention: Pharmacokinetics of Polyphenols and Pentacyclic Triterpenes and Assessment of Antioxidant, Cardiovascular and Anti-inflammatory Biomarkers

Olives and olive oil are typical components of the Mediterranean diet being part of its cultural and gastronomic heritage. Since ancient times, olives have been used either for both, oil extraction or whole fruit consumption as table olives. Olive oil stands out from both the nutritional and the health point of view. However, the effect of table olives consumption remains almost unknown. The beneficial properties of olive oil have been initially ascribed to the high concentration of oleic acid. Nowadays, these positive effects have been attributed also to minor compounds such as polyphenols or pentacyclic triterpenes. Table olives contain a higher amount of both polyphenols and pentacyclic triterpenes than their oil, with the same healthy fatty acid profile. Therefore, the present intervention aims at investigating the pharmacokinetic of polyphenols and pentacyclic triterpenes after a single olive intake as well as the assessment of the effect of the consumption of olives during 30 days on the overall health status playing particular attention to the anti-inflammatory, antioxidant and cardiovascular biomarkers.
