Extra Virgin Olive Oil (EVOO) Health Benefits on Cognitive Function in Older Adults

Fat is satiating and delicious yet foreign and feared. For many years, fat has been considered taboo for its association with processed foods, weight gain, and, well, fat.

But is it time to reconsider? And are all fats really created equal?  

Regardless, I hope you’re ready to make room for extra virgin olive oil because the health benefits it provides are seemingly endless.


A recent study in Barcelona, Spain confirms. The study followed 447 cognitively healthy volunteers for a span of roughly 4 years. The study included three groups: a control group advised to reduce dietary fats, a group assigned to consume a liter of extra virgin olive oil per week, and another to consume 30 grams of mixed nuts per day through a Mediterranean diet.

Based on six cognitive tests, the studies evaluated provide evidence that a Mediterranean diet supplemented with olive oil or nuts over a Mediterranean diet with reduced dietary fats showed an Improvement in Cognitive Function for older populations. This indicates the Mediterranean diet, rich in extra virgin olive oil may benefit older populations who are experiencing age-related cognitive decline

It’s clear that reducing fats is not a solution to improving age-related cognitive decline. But a Mediterranean diet supplemented with olive oil or nuts could be! It’s associated with improved cognitive function as opposed to a reduced-fat Mediterranean diet making the addition of extra virgin olive oil (EVOO) and nuts beneficial to your diet. So keep your fats in your diet and choose them wisely. High quality extra virgin olive oil (EVOO), like Olivaio, is a great option. 

And next time you check your pantry or fridge, grab a healthy fat that compliments your dish. Better yet, make a dish that includes nuts and extra virgin olive oil (EVOO)!

Mediterranean dishes sound delicious right about now. Just down below I have some quick and healthy dishes for you. Enjoy!
