"Nutrition has been linked to cognitive performance, but researchers have not pinpointed what underlies the connection. A new study found that monounsaturated fatty acids -- a class of nutrients found in olive oils, nuts and avocados -- are linked to general intelligence, and that this relationship is driven by the correlation between MUFAs and the organization of the brain's attention network."

"The researchers found that general intelligence was associated with the brain's dorsal attention network, which plays a central role in attention-demanding tasks and everyday problem solving. In particular, the researchers found that general intelligence was associated with how efficiently the dorsal attention network is functionally organized used a measure called small-world propensity, which describes how well the neural network is connected within locally clustered regions as well as across globally integrated systems"
