Olive oil is only as healthy as its polyphenols.
A review of 26 human studies compared the two: olive oil high in polyphenols, and olive oil low in them. Only the high-polyphenol oils showed a meaningful effect. The low ones showed little to none.
Which is confronting, because most oil in the supermarket is low in polyphenols. “Extra virgin” says nothing about the number.
So there is really only one thing to check before you buy: the lab result. A serious brand publishes it. Ours is 1,250+ mg/kg, around 7x the average, tested every batch by an independent lab.
