Phase 1 |
Detailed Description
The study is divided in two sub-studies to explore each objective.
One the one hand, a group of people will drink olive oil, or wine, or both. This is done to see if combining these two drinks will improve the absorption and bioavailibility of phenolic compounds that they contain, promoting by synergy their antioxidant activity at a postprandial level. The main compounds studied are the Resveratrol (RSVT), the Hydroxytyrosol (HT), tyrosol (TIR) and their metabolits.
One the other hand, an group of people will drink 3 different beers ( with 3 different degrees of alcohol), or wine, in order to study the absorption of TIR in relation to the alcohol degree. It also aims at assessing if the gas contained in beer contributes to TIR absorption.
At different times after the administration of drinks, urine and blood samples will be collected.

Endothelial function will be assessed as flow-mediated dilation using endoPAT 2000 (Itamar Medical device). Flow-mediated dilation is the most widely used method to test endothelial function since it is non-invasive, and measures by ultrasounds the response to increased shear stress, commonly in the brachial artery
