From CNBC:
When it comes to enhancing brain health and reducing the risk of dementia, one kitchen staple consistently rises to the top: olive oil.
As a medical professional who specializes in disease prevention and longevity, I frequently recommend olive oil as a cornerstone of a brain-healthy diet, largely due to its powerful antioxidants and anti-inflammatory properties. In fact, a 2024 Harvard study of 92,383 American adults found that regardless of genetic predisposition and overall diet, participants who consumed at least 7 grams of olive oil per day had a 28% lower risk of dementia-related death compared to those who never or rarely consumed olive oil.
