Study: Mediterranean diet may delay cognitive decline
The News Journal

A Mediterranean diet, traditionally known as a "heart-healthy" nutrition plan, is rich in fruits, vegetables, whole grains, legumes, nuts and emphasizes replacing butter with healthy fats, such as olive oil.Participants with a high risk for heart issues were split into three groups with three different dietary guidelines. One group ate a Mediterranean diet supplemented with olive oil, another ate a Mediterranean diet rich with nuts and the third group was just recommended to decrease dietary fats. The participants' median age was 66.Three-hundred-thirty-four participants underwent cognitive tests after about four years of following the diets. Researchers found that participants who ate the Mediterranean based diets scored better on tests that measured learning strategies, short-term auditory and verbal memory and color trail tests.
