Olive oil helps the different parts of your brain communicate better with each other.

See the scientific wording

Olive oil consumption enhances functional connectivity between different brain regions.

Why this might work

Eating olive oil brings helpful plant compounds to the brain that fight damage and inflammation. This keeps the brain's protective barrier strong and stops harmful proteins from building up. As a result, brain cells work better and communicate more effectively with each other.

What the research says

3 studies

  1. Study: Extra-Virgin Olive Oil Enhances the Blood–Brain Barrier Function in Mild Cognitive Impairment: A Randomized Controlled Trial

    People who ate extra-virgin olive oil for six months had better communication between brain areas, but those who ate refined olive oil did not see this benefit.

  2. 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 found that a special kind of olive oil helped the brains of people with memory problems communicate better, supporting the idea that olive oil can improve brain connectivity.

  3. Study: Resting-state brain connectivity following extra virgin olive oil intake in healthy adults: a randomised crossover pilot neuroimaging substudy.

    The study found that drinking extra virgin olive oil made the visual part of the brain's connections stronger compared to regular olive oil.
