The Claim
In older adults at high cardiovascular risk, a Mediterranean diet supplemented with extra-virgin olive oil has a beneficial effect on cognitive performance and mild cognitive impairment, and this effect is independent of age, education, APOE genotype, smoking, physical activity, body mass index, hypertension, dyslipidemia, diabetes, and other confounders.
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.
Eating a Mediterranean diet with extra-virgin olive oil helps older adults with heart risk keep their thinking and memory sharp, and this benefit isn't just because of their age, education, genetics, smoking, weight, high blood pressure, cholesterol, or diabetes. The diet itself makes the difference.

Eating a Mediterranean diet with extra-virgin olive oil provides substances that calm the body's inflammation and stop harmful molecules from damaging brain cells. This keeps the blood vessels in the brain healthy and prevents memory and thinking problems.
What the research says
1 studyStudy: Virgin olive oil supplementation and long-term cognition: the Predimed-Navarra randomized, trial
The study showed that older people at risk of heart disease who ate a Mediterranean diet with extra-virgin olive oil had better memory and thinking, even after accounting for other health issues like age, education, and blood pressure, so the diet itself seems to help the brain.
