Mediterranean-style diet is good for your mind.
The Mediterranean diet has a positive impact on cognitive function, but an inconsistent effect on mild cognitive impairment (MCI, which often is a precursor to Alzheimer's disease), according to researchers who analyzed 12 studies. In 75 percent of the studies, a higher adherence to a Mediterranean diet was associated with better cognitive function, lower rates of cognitive decline, and a reduced risk of Alzheimer's disease. A Mediterranean-style diet features an abundance of plant foods, including vegetables, fruit, legumes, and whole grains, olive oil as the primary fat, and limited meats and sweets. Previous research has tied the diet with a lower risk of diabetes and heart disease. The study was published in the July 2013 issue of Epidemiology.
