In the study, healthy people aged 65-77 who drank concentrated blueberry juice every day showed improvements in cognitive function, blood flow to the brain and activation of the brain while carrying out cognitive tests. There was also evidence suggesting improvement in working memory.

Of the 26 healthy adults in the study, 12 were given concentrated blueberry juice providing the equivalent of 230g of blueberries once a day, while 14 received a placebo.

Before and after the 12-week period, participants took a range of cognitive tests while an MRI scanner monitored their brain function and resting brain blood flow was measured.

Compared to the placebo group, those who took the blueberry supplement showed significant increases in brain activity in brain areas related to the tests.
