The Claim
Consumption of extra virgin olive oil increases resting-state functional connectivity in the left occipital cortex, specifically within the visual network, including superior and inferior lateral areas associated with visuospatial attention, motion perception, and object recognition.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Extra virgin olive oil strengthens connections in a part of the brain that processes what you see. This area is on the left side at the back, and it's involved in paying attention to visual details, noticing movement, and recognizing objects.
See the scientific wording
The increase in resting-state functional connectivity after extra virgin olive oil intake is localized to the left occipital cortex, specifically the visual network, including superior and inferior lateral areas involved in visuospatial attention, motion perception, and object recognition.
Extra virgin olive oil contains special plant chemicals called polyphenols. When you drink it, these chemicals go into your blood and then travel to your brain. In the brain, they protect brain cells from damage and help them talk to each other better. This makes the connections in the part of the brain that handles vision stronger, so your brain areas that process what you see work together more smoothly.
What the research says
1 studyThe study shows that drinking extra virgin olive oil improves brain connections in the back part of the brain that processes vision, which matches the claim, but it doesn't say whether it's only on the left side or exactly which visual areas are involved.
