Does olive oil have phenols?
Olive oil is a source of at least 30 phenolic compounds. The major phenolic compounds in olive oil are oleuropein, hydroxytyrosol and tyrosol. Recently there has been a surge in the number of publications that has investigated their biological properties.
Does heating olive oil destroy polyphenols?

How much hydroxytyrosol polyphenols is in olive oil?
Hydroxytyrosol, comprising over 40 % of total olive oil phenolics, mainly contributed to the antioxidant activity of olive oils.
Which olive oil has the most phenols?
extra virgin olive oil

Why you shouldn’t cook with extra virgin olive oil?
While EVOO is fairly stable to heat in terms of its fat composition, it is quite unstable to heat in terms of its phenol and polyphenol composition. Recent studies show that phenols and polyphenols in EVOO—for example, hydroxytyrosol or luteolin —are not stable to heat and degrade relatively quickly.
Is Avocado oil healthier than olive oil?
