• •Olive oil, especially extra-virgin, is linked to lower rates of heart disease, type 2 diabetes, and dementia.
• •Polyphenols in olive oil are believed to protect the brain by reducing inflammation and preventing damage from free radicals.
• •Extra-virgin olive oil shows greater cognitive benefits compared to standard olive oil due to higher polyphenol levels.
• •Replacing animal fats with olive oil or other plant oils is a positive step for brain health.

Research suggests that olive oil, particularly the extra-virgin variety, can play a role in fighting cognitive decline and may even protect against Alzheimer's disease. Studies show that the consumption of olive oil is linked to a lower risk of dementia-related death, with the benefits potentially stemming from its high polyphenol content. While extra-virgin olive oil is considered the best choice, other plant-based oils can also be a healthy alternative to animal fats. Ultimately, opting for quality olive oil and considering other plant-based oils could be a beneficial strategy for brain health.
