Mediterranean diet reduces brain shrinkage in old age

  • The Mediterranean diet is the diet most associated with cognitive and health benefits in older adults.
  • A new study has found larger brain volumes among those following this sort of diet, equivalent to that of brains five years younger.
  • Much of this was associated with two components of the diet in particular: eating fish regularly, and eating less meat.

Another study adds to the growing evidence that a Mediterranean diet is good for the aging brain.

The New York study used data from 674 non-demented older adults (average age 80). It found that those who closely followed such a diet showed significantly less brain shrinkage. Specifically, total brain volume was an average 13.11 milliliters greater, with grey matter volume 5 millilitres greater, and white matter 6.4 millilitres greater.

Eating at least five of the recommended Mediterranean diet components was associated with benefits equivalent to five years of age. By far the most important of these components was regular fish and reduced meat intake — at least 3 to 5 ounces of fish weekly; no more than 3.5 ounces of meat daily.

This is consistent with a considerable amount of research indicating the benefits of fish in fighting age-related cognitive decline.
