People who eat a diet rich in fish, fruits, vegetables and low in meat may lose fewer brain cells as they age. Also known as: Brain Shrinkage according to a new study.

In the study of 674 older adults, the researchers looked at whether the participants’ diets during the past year included the following nine components of the so-called Mediterranean diet:

eating lots of:

  • vegetables,
  • legumes,
  • cereals,
  • fish,
  • fruits
  • nuts;
  • consuming healthy monosaturated fats
    • like olive oil
      • avoiding saturated fats;
    • drinking moderate amounts of alcohol;
    • eating low amounts of meat and dairy products.

The average age of the people in the study was 80.

Researchers found:

The researchers scanned the participants’ brains, finding those whose diets included at least five of these nine components had brain volumes measuring 13.11 milliliters larger  on average, compared with those did not.

This difference in brain volume between the two groups is equivalent to the amount of shrinkage that happens over five years of aging, the researchers said.

“These results are exciting, as they raise the possibility that people may potentially prevent brain shrinking and the effects of aging on the brain simply by following a healthy diet,” study author Yian Gu, of Columbia University in New York, said in a statement.

When the researchers took a closer look at the relationship between brain shrinkage and the Mediterranean diet, they found that the diet’s protective effect was driven to the greatest extent by two components: eating more fish and eating less meat.

The finding suggests:

This finding suggests that “eating at least 3 to 5 ounces of fish weekly or eating no more than 3.5 ounces of meat daily may provide considerable protection against loss of brain cells equal to about three to four years of aging,” Gu said. [7 Ways the Mind and Body Change With Age]

None of the people in the new study had dementia. The researchers noted, greater amounts of brain shrinkage have been linked to a greater risk of cognitive decline.

The new study was observational, and more research is needed to examine the relationship between the Mediterranean diet and brain structure, Gu told Live Science. The new study does not prove that following the Mediterranean diet prevents brain shrinkage; it  shows there is a link between the two.

The mechanism between the Mediterranean diet and a greater brain volume is not clear. It may have something to do with the beneficial effects of nutrients present in the foods, the researchers said. For example, omega-3 fats as well as vitamins B and D in fish have been shown to promote the growth of neurons and slow brain shrinkage, they said.

The new study was published today (Oct. 21) in the journal Neurology.
