Researchers at the University of Exeter and the University of the West of England recruited 26 healthy seniors aged 65 to 77, 12 of whom consumed 30 ml of blueberry juice per day for 12 weeks, equivalent to 230 grams of blueberries. 14 people only took placebo. Subjects subsequently underwent a series of cognitive ability tests and brain MRI scans.
The results showed that compared with the elderly in the placebo group, the elderly who drank the blueberry juice concentrate daily had a certain degree of improvement in cognitive function, brain blood supply, and brain activity, and the working memory was also improved. Working memory refers to the system in which people temporarily store information while completing cognitive tasks.
Previous studies have shown that a higher proportion of vegetables and fruits in the diet helps reduce the risk of dementia. The researchers pointed out that blueberry contains more flavonoids, flavonoids have antioxidant and anti-inflammatory effects, which may be related to the health benefits of blueberry juice concentrate.
The research report has been published in the Canadian journal Applied Physiology, Nutrition and Metabolism. However, it should be noted that the blueberry concentrate used in the study and some research funds are from a juice producer.Please feel free to contact us or send an email to [email protected]
