Recent research suggests that regular olive oil consumption may significantly lower the risk of dying from dementia-related causes.
Olive Oil and Dementia Risk
A study published in JAMA Network Open examined over 92,000 U.S. adults across 28 years and found that those who consumed more than 7 grams (about half a tablespoon) of olive oil daily had a 28% lower risk of dementia-related mortality compared to those who rarely consumed it.

The study also revealed that swapping just one teaspoon of margarine or mayonnaise with olive oil led to an 8% to 14% reduction in dementia-related death rates.
Replacing Unhealthy Fats with Olive Oil
This suggests that olive oil itself, rather than overall diet quality, plays a key role in brain health.
Replacing Unhealthy Fats with Olive Oil
Olive oil is rich in monounsaturated fats and polyphenols, which have antioxidant and anti-inflammatory properties.

These compounds help reduce oxidative stress and inflammation, both of which are linked to cognitive decline.
How Olive Oil Protects the Brain
Adding at least half a tablespoon of olive oil daily—whether as a salad dressing, drizzled over vegetables, or as a butter alternative—is a simple and effective way to support brain health and longevity.
