Fish-Rich Mediterranean Diet Associated With Higher Cognition

Consuming a Mediterranean diet, particularly with lots of fish, was associated with higher cognitive function, National Eye Institute (NEI) researchers and colleagues reported recently. The cognition study is a post hoc analysis of data from the Age-Related Eye Disease Study (AREDS) and AREDS2. The multicenter US clinical trials tracked the natural history of age-related macular degeneration (AMD) and cataract and evaluated vitamin supplements’ effects on their progression. At baseline in both studies, researchers used food questionnaires to assess 9 components of the Mediterranean diet: whole fruits, vegetables, whole grains, nuts, legumes, fish, and olive oil and reduced consumption of red meat and alcohol.
