Most of use go on a diet to lose weight or to improve our physical condition. But researchers in Australia have concluded that the Mediterranean diet is not only good for you physically, but mentally as well.
Writing in the journal Frontiers in Nutrition, lead author Roy Hardman from Swinburne University of Technology in Melbourne and his colleagues say the diet appears to slow cognitive decline.
The Mediterranean diet includes a lot of plant foods, like leafy greens, fresh fruit and vegetables, cereals, beans, seeds, nuts, and legumes. There is less dairy and red meat, and olive oil is the preferred source of fat.
"The most surprising result was that the positive effects were found in countries around the whole world,” Hardman said. “So regardless of being located outside of what is considered the Mediterranean region, the positive cognitive effects of a higher adherence to a MedDiet were similar in all evaluated papers."
Heart healthy too

And in line with this latest research from Australia, the Mayo Clinic staff notes that the Mediterranean diet has also been associated with a lower incidence of Alzheimer's disease.
