Olive Oil (Early Harvest)

Overview

Early harvest extra virgin olive oil is a precision food in the BRAIN Diet, harvested from olives picked earlier in the season when they contain significantly higher concentrations of bioactive compounds. Olive oil's brain benefits come from polyphenols, not fatty acids. Early harvest oils have substantially higher levels of the key secoiridoids and phenolics that provide brain health benefits:

  • Oleuropein aglycone → mitophagy, SIRT1, AMPK activation (up to 53-56% more CoQ10 than later harvest)
  • Oleocanthal → NF-κB inhibition, anti-inflammatory effects
  • Oleacein → antioxidant, NRF2 activation
  • Tyrosol / Hydroxytyrosol → neuroprotective effects

These enhanced bioactive levels support mitochondrial function, antioxidant networks, and anti-inflammatory pathways, making early harvest olive oil a valuable component of precision dietary strategies for brain health. The implementation of the BRAIN diet must go beyond a standard nutrient density focus; it's about choosing foods for their specific bioactive potential: early harvest extra virgin olive oil with higher levels of CoQ10, oleuropein, oleocanthal, oleacein, hydroxytyrosol, tyrosol, and total polyphenols.

Electron transport chain cofactor and antioxidant relevant to mitochondrial function

Chemical structure

Oleacein

Secoiridoid polyphenol in extra-virgin olive oil; antioxidant and NRF2 activation

Chemical structure

Oleocanthal

Secoiridoid polyphenol in extra-virgin olive oil; NF-κB inhibition and anti-inflammatory effects

Chemical structure

Oleuropein

Major secoiridoid polyphenol in olive oil; oleuropein aglycone supports mitophagy, SIRT1, and AMPK activation

Chemical structure

Preparation Notes

  • Best used for salad dressings, drizzling, and low-heat applications to preserve polyphenols and CoQ10
  • Avoid high-heat cooking to prevent degradation of bioactive compounds
  • Store away from heat and light to preserve antioxidant properties and CoQ10 levels
  • Look for harvest date information on labels; early harvest typically occurs in September-October (Northern Hemisphere)
  • Total CoQ dropped by 53%-56% between three weeks of the harvesting of two brands, highlighting the critical importance of harvest timing
  • Higher polyphenol content provides stronger antioxidant and anti-inflammatory effects compared to standard EVOO
