A collaborative research project now underway at the North Carolina Research Campus in Kannapolis, North Carolina, will determine if eating blueberries and doing light exercise can help older adults keep their memory strong. During the course of the three-year study, the researchers will work with 240 participants between the ages of 65 and 85 to see if these simple habits can slow down memory loss as people get older.

The 12-week study requires volunteer participants to consume a small amount of blueberry powder dissolved in water (or a placebo without blueberry) everyday and complete 45 minutes of walking or stretching. The goal of this study is to see if these healthy habits like eating blueberries and doing regular light exercise may help improve memory and slow down memory loss in older adults. 

Previous studies have shown that blueberries contain a large quantity of bioactive compounds, called anthocyanin, that were shown to enhance neuronal activity, reduce oxidative stress and inflammation and improve blood flow in the brain. Moreover, clinical studies suggested that blueberries can improve memory performance and reduce cognitive decline with aging.

One participant shared, “I joined the study because I had experienced some memory loss and thought that it would be an opportunity to potentially help others through the research.” She’s been so inspired, she planted a blueberry bush to enjoy blueberries more often.

Mary Ann Lila, PhD, an expert in the field of polyphenols and human health, said “This study is interesting and exciting because it may show how two simple lifestyle changes like eating blueberries and staying active can support the brain and body.” David Nieman, PhD, director of the Appalachian State University Human Performance Lab is overseeing the exercise component of the study, while Carol Cheatham, PhD at the UNC-CH Nutrition Research Institute will lead the cognitive evaluations. This multi-university collaboration is a hallmark trait of research conducted at the NC Research Campus, in Kannapolis, NC, where all three universities have a presence.

This study could help doctors guide older patients to better cognitive health through simple habits. For more information or to determine participant eligibility, visit the recruitment website or contact Dr. Camila Olson at 704-250‑5352.

The study, Age-related Cognitive Changes: Effect of Combined Flavonoid Intake and Physical Exertion Mediated by the Gut Microbiome, is supported by the National Institutes of Health – National Institute on Aging.
