Drinking concentrated blueberry juice improves brain function in older people, according to research by the University of Exeter.
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 outcognitive tests.
There was also evidence suggesting improvement in working memory.
Blueberries are rich in flavonoids, which possess antioxidant and anti-inflammatory properties.
Dr Joanna Bowtell, head of Sport and Health Sciences at the University of Exeter, said: “Our cognitive function tends to decline as we get older, but previous research has shown that cognitive function is better preserved in healthy older adults with a diet rich in plant-based foods.
“In this study we have shown that with just 12 weeks of consuming 30ml is more than an ounce ours is a gram 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.”
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.that is a 1/4 of a lb lots of money compared to us without all the other components .they will never compare to ours.
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.
The study excluded anyone who said they consumed more than five portions of fruit and vegetables per day, and all participants were told to stick to their normal diet throughout. Our product has more than 5 servings we win
Previous research has shown that risk of dementia is reduced by higher fruit and vegetable intake, and cognitive function is better preserved in healthy older adults with a diet rich in plant-based foods.
Flavonoids, which are abundant in plants, are likely to be an important component in causing these effects.
