Study found the diet was linked to improved attention and a higher IQ.
Monounsaturated fatty acids — or MUFAs — have been regularly linked to health benefits.
MUFAs are particularly prevalent in the diet traditionally eaten in Mediterranean countries.
The presence of these fatty acids in the diet may help to explain the health benefits of certain types of foods, such as:
- Olive oil
- Peanut oil
- Nuts, such as almonds, cashews, pecans and macadamias
- Canola oil
- Olives
- Nut butters
The conclusions come from a study of 99 healthy older adults.
Each provided blood samples and had intelligence tests along with brain scans.
Their intelligence was also linked to a more efficient attentional system in the brain.
Professor Aron Barbey, who led the study, said:
“Our findings provide novel evidence that MUFAs are related to a very specific brain network, the dorsal attentional network, and how optimal this network is functionally organized.The next step will be to directly test whether a higher intake of MUFAs will affect cognition and intelligence.
Our results suggest that if we want to understand the relationship between MUFAs and general intelligence, we need to take the dorsal attention network into account.
It’s part of the underlying mechanism that contributes to their relationship.”
Professor Barbey said:
“Our ability to relate those beneficial cognitive effects to specific properties of brain networks is exciting.
This gives us evidence of the mechanisms by which nutrition affects intelligence and motivates promising new directions for future research in nutritional cognitive neuroscience.”
