Strengthening the Brain

The MIND diet is a hybrid of the Mediterranean diet and the Dietary Approaches to Stop Hypertension diet (its name is a combo of those two diets). And it just passed its latest test.

In a study published in September in the Journal of Alzheimer’s Disease scientists show the MIND diet can slow cognitive decline and reduce the risk of Alzheimer’s disease dementia.

This held true despite the fact that study participant’s brains still developed the abnormal clumps of proteins associated with Alzheimer’s disease.

First author Klodian Dhana is an assistant professor at Rush University. His focus is on identifying risk factors of dementia. In the absence of a cure for Alzheimer’s disease, scientists aim to identify which modifiable lifestyle factors can lower the risk of cognitive decline. Nutrition, he tells me, “has gained interest because it can be readily modified.”

“I hope the findings of this study motivate people to practice a healthier lifestyle through nutrition, exercise, and cognitive activities,” he says.

HOW THE DISCOVERY WAS MADE — Dhana and colleagues examined data pulled from Rush University’s ongoing Memory and Aging Project representing 569 participants. These individuals lived in the greater Chicago area and began sharing their vitals in 1997. In 2004, an annual food frequency questionnaire was thrown into the mix, which evaluated how often they ate specific foods. All participants agreed to undergo clinical evaluations while they were alive and a brain autopsy when they died.

Each participant was assigned a MIND diet score based on how closely they adhered to meals within it. Within the MIND diet are 10 brain-healthy food groups and five unhealthy groups: The unhealthy group includes butter and stick margarine, cheese, fried and fast food, pastries and sweets, and red meat.  READ MORE...
