WorkplanOlive oils with low,
medium and high phenolic content will be administered to healthy volunteers during three
weeks. Three main points will be examined:
1. The role of olive oil and olive oil phenolic compounds in the protection of oxidative
stress.
2. Oxidative stress occurs after meals with fat. This is called "postprandial
oxidative stress". The beneficial effect of olive oil and that of its phenolic
compounds on the postprandial oxidative stress will be examined. 
3. Whether the substitution of other raw fats by olive oil results in healthier fatty acid
composition of the LDL.
One important point of the study is that the olive oil administered dose will be
close to that used daily in Mediterranean countries (25 mL/day).
