A small study in the journal Applied Physiology, Nutrition, and Metabolism showed an improvement in cognitive function, bloodflow to the brain, and brain activation in older people who drank concentrated blueberry juice every day for 12 weeks.

The 26 participants were healthy adults between the ages of 65 and 77. People who consumed more than 5 daily servings of fruits and vegetables were excluded from the study. Twelve participants consumed 30mL (less than a quarter cup) of the concentrated juice each day, while the other 14 received a daily placebo instead.

The participants did a variety of cognitive tests before and after the study period. Magnetic resonance imaging (MRI) scans collected information about bloodflow and brain function during these tests.

Participants in the blueberry juice group showed statistically significant increases in brain activity by the end of the study compared to those in the placebo group.

The study was led by researcher Joanna Bowtell.
