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. (Source: Medical Express)

Working memory allows the brain to briefly hold immediate information while it’s needed in the short-term. Most kids with learning and attention issues have trouble with working memory.[1]

The study showed that in just 12 weeks of consuming 30ml of blueberry concentrate daily may improve blood flow to the brain, brain activation, as well as some aspects of working memory in healthy older adults.

During the study, one group 12 participants were given concentrated blueberry juice once a day, and the other group 14 people were given a placebo. The participants took a range of cognitive tests, before and after the 12-week study period. MRI scans monitored to monitor brain function and resting blood flow.

Compared to the placebo group, participants who took the blueberry concentrate showed significant increase in brain activity and cognitive function, as well as improved blood flow to the brain.

In a previous post, we listed blueberries among the 10 brain and memory boosting foods, herbs, and supplements.

So, can you simply eat blueberries for similar effect? Yes, but you would have to eat 230g of blueberries daily. That’s about two and a quarter cups of blueberries every day. I don’t know about you, but I’ll go with concentrate. Blueberry supplements are available in liquid and pill form as well.

Eating blueberries is still a good thing – you don’t want to replace real fruits with juices.
