ScienceDaily reports that:
In a population of initially well-functioning older adults, we found a significant correlation between strong adherence to the Mediterranean diet and a slower rate of cognitive decline among African American, but not white, older adults. Our study is the first to show a possible race-specific association between the Mediterranean diet and cognitive decline.

Let me take a wild guess... while the Mediterranean Older White Adults are nuts ([citation] [wikipedia.org]... watch it or read it), at the same age the American Older White Adults are already salads (which is a species of vegetable)
The fact that older African-Americans jumped [wikipedia.org] or danced [imdb.com] before?
