The Claim

Daily consumption of 50 mL of Greek high-phenolic early harvest extra virgin olive oil for 12 months increases the flexibility index of resting-state EEG brain connectivity, reflecting more adaptable communication between brain areas, in older adults with mild cognitive impairment, with a more prominent effect than moderate-phenolic olive oil or Mediterranean diet alone.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Older adults with mild memory problems who take a special olive oil (early harvest, high in polyphenols) every day for a year get a more flexible brain, meaning their brain areas can communicate more easily. This works better than taking other olive oils or just following a Mediterranean diet.

See the scientific wording

Daily consumption of 50 mL of Greek high-phenolic early harvest extra virgin olive oil for 12 months increases the flexibility index of resting-state EEG brain connectivity, reflecting more adaptable communication between brain areas, in older adults with mild cognitive impairment, with a more prominent effect than moderate-phenolic olive oil or Mediterranean diet alone.

Why this might work

Drinking a special olive oil with lots of healthy plant chemicals helps protect brain cells. These chemicals calm down overactive brain signals and allow brain areas to communicate in a more flexible way, which helps with memory and thinking.

  1. Study: Greek High Phenolic Early Harvest Extra Virgin Olive Oil Reduces the Over-Excitation of Information-Flow Based on Dominant Coupling Mode (DoCM) Model in Patients with Mild Cognitive Impairment: An EEG Resting-State Validation Approach

    The study showed that drinking a special olive oil every day for a year helped make brain connections more flexible and less noisy in older people with memory issues, and it worked better than regular olive oil or just a healthy diet.
