More evidence that a Mediterranean-style diet is good for the brain comes from an analysis of data from 7,756 U.S. adults, ages 50 to 85, published in Alzheimer’s & Dementia. The researchers scored the participants’ diets (as assessed by questionnaires at the study’s baseline) for how closely they adhered to a version of the Mediterranean diet—rich in whole grains, vegetables, fruits, nuts, fish, legumes, and olive oil, with little red meat and a moderate amount of alcohol.
Those whose diets most adhered to that eating pattern scored better on tests of cognitive function over the next two to 10 years than those whose diets adhered the least. High consumption of fish and vegetables in particular was linked to better cognitive function. In addition, a high intake of fish—but not the Mediterranean diet overall—was associated with a slower rate of cognitive decline over five to 10 years.
