Hypothesis: A functional olive oil tailored to provide the best relationship between phenolic compounds (amount and type) phenolic bioavailability and bioactivity (antioxidant and anti-endothelial dysfunction) will be a useful tool for increasing not only circulating HDL cholesterol concentration, but also the functionality (antioxidant, anti-inflammatory, and reverse cholesterol transport capacity) of human HDL in vivo.
The first step is to determine, in healthy human subjects in postprandial condition, the best relationship between phenolic compounds (amount and type) / bioavailability and bioactivity (antioxidant, anti-inflammatory and anti-endothelial dysfunction) using olive oils enriched with its own broad-spectrum phenolic compounds.

Estimate

Other olive oil

Each volunteer will be given, in random order, a single dose of 30 ml on a base of 80 g bread, of the following functional olive oils (FOO): FOO750 ppm, FOO500 ppm, which are enriched with two different amounts of broad-spectrum phenolic compounds from the virgin FOO250 ppm; all prepared at the Universitat de Lleida. Post-ingestion the volunteers will rest for 8h in a comfortable warm room. During the run-in period of 2 weeks prior the first postprandial study and 1 week between each FOO treatment period, all subjects will undergo a 2-day pre-treatment wash-out period of a phenol-free diet (saturated fatty acids in the diet will be 10-13% of energy in an isocaloric diet). Volunteers will avoid non-essential physical activity during the 3 days prior to the treatment day.
