The Claim

Daily consumption of 50 mL of Greek high-phenolic early harvest extra virgin olive oil for 12 months significantly reduces the frontal theta/beta ratio in the eyes-open resting-state EEG of older adults with mild cognitive impairment, indicating improved attentional control (p=0.0032).

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

Every day for a year, older adults with mild memory problems drank a small glass of a special Greek olive oil made from early-picked olives that is rich in healthy plant compounds. Brain wave tests showed a specific change in brain activity that means they became better at focusing and paying attention.

See the scientific wording

Daily consumption of 50 mL of Greek high-phenolic early harvest extra virgin olive oil for 12 months significantly reduces the frontal theta/beta ratio in the eyes-open resting-state EEG of older adults with mild cognitive impairment, indicating improved attentional control (p=0.0032).

Why this might work

Eating a special olive oil with lots of natural plant chemicals every day for a year helps protect brain cells and calm down overactive brain signals. This makes the brain's communication more organized and less chaotic, which helps people with memory problems pay attention better. The brain waves become more balanced, showing improved focus.
