Of the studies in question, Harvard noted that one of them: “published in 2015 and updated in 2018 compared healthy older adults who followed a Mediterranean diet with extra olive oil or extra nuts versus a control reduced-fat diet.
“The enhanced Mediterranean diet groups fared equally well, and both had better cognitive performance outcomes than the reduced-fat diet group.”
While the results of this study were promising, Harvard added a key caveat: “No study, however, had been able to determine the critical components of the Mediterranean diet that makes it so good for the brain.”
That is until recently.
