What Makes Olive Oil High in Polyphenols?
Not all olive oils are the same. Several factors influence polyphenol levels:
- Early harvest – Greener olives generally contain more polyphenols.
- Olive variety – Varieties such as Koroneiki are naturally rich in polyphenols.
- Cold extraction – Gentle processing helps preserve natural compounds.
- Freshness – Recently harvested oils generally contain higher levels.
