A new study shows that eating vegetables protects brain function in aging adults. As part of the Chicago Health and Aging Project (CHAP), researchers at Rush University Medical Center examined the association between rates of cognitive change and dietary consumption of fruits and vegetables among 3,718 participants, aged 65 years and older. Those who consumed greater than 2.8 servings of vegetables per day had significantly slower rates of mental decline than those who ate fewer servings. Green leafy vegetables, in particular, were most strongly associated with a decreased rate of mental decline. Fruit consumption was not associated with cognitive change.
