Blueberry Juice Improves Brain Function In Older People: Study

A recent study claims that drinking 30ml of concentrated blueberry juice daily can improve brain function of elderly people.

The brain function in older people tends to decline with age, but a glass of blueberry juice can improve brain blood flow, boost brain activation and some aspects of working memory amongst older adults.

Researchers studied 26 healthy adults, out of which 12 adults were given concentrated blueberry juice, providing the equivalent of 230g of blueberries, once a day, while 14 were given a placebo.

Those who consumed the blueberry supplement showed increased signs of blood flow to the brain and cognitive function, compared to the group that was given placebo.

Experts also indicated a significant improvement in working memory.

“The study shows that with just 12 weeks of consuming 30ml of concentrated blueberry juice every day, brain blood flow, brain activation and some aspects of working memory were improved in this group of healthy older adults,” said Joanna Bowtell from the University of Exeter in Britain.

The researchers pointed that blueberries are rich in flavonoids, a component found abundantly in plants. These flavonoids possess antioxidant and anti-inflammatory properties, which prompt in causing these positive effects in the elderly.

The study was published in the journal Applied Physiology, Nutrition, and Metabolism.
