The Claim

In older adults with mild cognitive impairment, after 12 months of daily consumption of Greek high-phenolic early harvest extra virgin olive oil, a reduction in the nonlinearity index of EEG brain connectivity is associated with improvements in neuropsychological test scores, as shown by multi-linear regression analysis (R²=0.1758, p=0.0365).

In plain English

In older adults with mild memory problems, eating a special type of Greek olive oil every day for a year was linked to better scores on thinking tests. The study found that this improvement came with a change in brain activity, where the brain's electrical signals became more regular and less jumbled.

See the scientific wording

Reduction in the nonlinearity index of EEG brain connectivity after 12 months of daily consumption of Greek high-phenolic early harvest extra virgin olive oil is associated with improvements in neuropsychological test scores in older adults with mild cognitive impairment, as shown by multi-linear regression analysis (R²=0.1758, p=0.0365).

Why this might work

The special olive oil contains natural chemicals called phenols. These phenols reduce damage in brain cells caused by stress. This makes the brain's signaling clearer and more balanced. As a result, the brain becomes more flexible and less overactive, which supports better thinking and memory.

    The study found that people with mild memory problems who took a special olive oil for a year had calmer brain activity, and those with the biggest change in brain activity also scored better on thinking and memory tests.
