Research by the University of Exeter has found that drinking concentrated blueberry juice could improve brain function in older people.
The study showed that people aged 65-77 who drank concentrated blueberry juice every day showed improvements in cognitive function and in some cases improvement in working memory.
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 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.”
26 healthy adults participated in the study – 12 had concentrated blueberry juice, while the rest received a placebo.
