Enhanced Mediterranean Diet for Alzheimer's Disease Prevention

Start: March 7, 2019
End: February 2023
Enrollment: 200

What Is This Study About?

This study investigates how the Mediterranean diet and low-fat eating patterns affect cognitive function and other measures, such as brain volume and blood pressure, in cognitively normal older adults. Participants will be randomly assigned to either a Mediterranean or low-fat diet for one year. The Mediterranean diet consists of fruits, vegetables, grains, dairy, olive oil, seafood, and nuts. Additionally, participants will be randomized to take either 2 grams of an omega-3 fatty acid supplement or placebo. During the study, participants will track the food they eat, be monitored by a registered dietitian, and engage in monthly food demonstrations and cooking classes. They will also pick up a bag of groceries weekly for six months from a local grocery store. After one year, people may continue in the study for up to two years for additional measurements.
