MSN, Yahoo highlight UC blueberry study
Regular consumption in middle age could reduce chances of dementia
A recently published study from the University of Cincinnati found that adding blueberries to the daily diets of certain middle-aged populations may lower the chances of developing late-life dementia.
Robert Krikorian, PhD, professor emeritus and director of the division of psychology in the UC College of Medicine’s Department of Psychiatry and Behavioral Neuroscience, led the double-blind study.
The researchers enrolled 33 patients from around the Cincinnati area between the ages of 50-65 who were overweight, prediabetic and had noticed mild memory decline with aging. Krikorian said this population has an increased risk for late-life dementia and other common conditions.
Over a period of 12 weeks, the patients were asked to abstain from berry fruit consumption of any kind except for a daily packet of supplement powder to be mixed with water and consumed either with breakfast or dinner. Half of the participants received powders that contained the equivalent of one-half cup of whole blueberries, while the other half received a placebo.
Krikorian said those in the blueberry-treated group showed improvement on cognitive tasks that depend on executive control.
“The sample size is an obvious limitation of the study, so it will be important to reproduce these findings, especially by other investigators,” Krikorian said. “In the meantime, it might be a good idea to consume blueberries on a regular basis.”
The study was highlighted by national and international publications, including The Daily Mail/MSN and Yahoo News, and by the local Simply Medicine program on 55KRC radio.
