Khaberni - In a new development that expands the understanding of the benefits of olive oil, a recent study revealed that consuming extra virgin olive oil may be linked to improved brain functions, and not just supporting heart health as commonly believed.
According to Verywell Health, the study showed that people who consume higher amounts of this type of oil have a higher diversity in gut bacteria, an indicator associated with microbiome health, along with better performance in cognitive tests.
The results suggest the role of what is known as the "gut-brain axis," a complex communication system that links the digestive system and the brain. It is thought that beneficial gut bacteria may produce compounds that affect inflammation and brain functions, explaining this connection.
Extra virgin olive oil also contains plant compounds known as "phenols," such as hydroxytyrosol and oleocanthal, which are antioxidants that may help reduce inflammation and protect nerve cells from damage as one ages.
A moderate amount could make a difference
The data showed that an increase in consuming olive oil by about 10 grams per day, just over two teaspoons, was linked to an improvement in cognitive outcomes, with the effect reaching about 53 grams per day, approximately four tablespoons.
Despite these positive indicators, researchers emphasize that the study is observational, meaning it shows a correlation between olive oil consumption and improved mental functions, but it does not prove that the oil is the direct cause of this improvement.
The results may also be affected by other factors, such as lifestyle or overall diet, which calls for more studies to confirm this relationship.
These findings bolster the growing hypothesis about the role of the microbiome in general health, especially in relation to the brain, opening up the field for a deeper understanding of how food affects cognitive functions as we age.
