400 adults, aged 73-76, participated in study

As we age, our brains naturally shrink and our risk of having a stroke, dementia or Alzheimer's rise, and almost everyone experiences some kind of memory loss.
Scientists know that people who exercise regularly, eat a healthy diet, avoid smoking and keep mentally stimulated generally have healthier brains than people who aren't as careful about diet and exercise.
Now, a new study seems to confirm that eating an easy-to-follow Mediterranean diet can have lasting benefits for brain health. The study was published Wednesday in the journal Neurology.
For the study, researchers analyzed the diets of about 400 adults, 73 to 76 years old, in Scotland over a three-year period. During this same time, the researchers took MRI scans of the participants to analyze their overall brain volume and thickness of the brain's cortex.
The researchers found that those who closely followed a Mediterranean-like diet were less likely to lose brain volume as they aged, compared with those who didn't follow such a diet.
However, more research is needed to determine an association between a Mediterranean diet and a specific effect on risk for degenerative brain diseases, such as dementia.
A 2015 study from the journal Neurology also suggests that a Mediterranean diet (which includes wine!) may help make your brain about five years younger.
