A new study suggests switching your morning cup of coffee or orange juice for a glass of blueberry juice to improve your memory.

The study, published in the Journal of Agricultural and Food Chemistry, found that drinking blueberry juice can boost memory.

According to Time magazine, researchers recruited 16 participants with an average age of 78 for the study. Nine volunteers were asked to drink about two cups of blueberry juice every day for 12 weeks, while the remaining volunteers drank a placebo instead.

They found that the blueberry-juice drinkers showed significantly better performance on two memory tests compared to the control group. In addition, the individuals who drank the juice had improved test scores at the end of the study period.

Researchers say all of the participants reported experiencing age-related cognitive problems prior to the study.

Researchers tell WebMD that there were also trends suggesting reduced symptoms of depression and lower glucose levels among the wild blueberry juice drinkers, but further research will be needed to confirm the results.

Blueberries contain high levels of antioxidants, phytoflavinoids, potassium and vitamin C, and previous studies have shown they can lower the risk of heart disease and cancer.

According to the Alzheimer’s Association, nutritional supplements containing coenzyme-Q10, gingko biloba, coral calcium, huperzine A and omega-3 fatty acids are also believed to help boost memory.
