— Findings about what specific components of
diets are most beneficial are frequently
changing.
However, an ongoing study of older adults
shows evidence that one type of diet can
help mitigate cognitive problems.
An ongoing prospective study called the
Chicago Health and Aging Project has shown
that adherence to the Mediterranean diet can
reduce the risk of cognitive decline with
older age.
“This diet emphasizes vegetables, fruits,
fish, olive oil, lower meat consumption, and
moderate wine and non-refined grain intake,”
said lead author Dr. Christy Tangney of Rush
University Medical Center in Chicago.
“Instead of espousing avoidance of foods,
the data support that adults over age 65
should look to include more olive oil,
legumes, nuts, and seeds in their diet in
order to improve their recall times and
other cognitive skills, such as identifying
symbols and numbers.”
The nearly 4,000 participants in this study
included black and white adults aged 65 and
older.
They were given a battery of cognitive tests
which were assigned scores and then a
clinical interview. Those who ranked in the
highest in terms of following such a
Mediterranean-type diet were more protected
from cognitive decline.
The adults were given these cognitive tests
every 3 years for 15 years. “Finally, we
want older adults to remember that physical
activity is an important part of maintaining
cognitive skills,” added Tangney.
