, May 19 (Xinhua) -- Research shows that drinking
a day can improve the brain power of
News Network reported on May 19.
, according to a study, improving memory, language fluency and brain response time by nearly 10 percent in less than two months, the Daily Mail reported on May 16. Scientists attribute the results to a chemical known as flavonoids. Flavonoids are a natural substance rich in citrus fruits.
it is said that flavonoids can improve memory by activating the signaling path of the sea mass. The sea mass is an area of the brain associated with learning and storing information.
team at the University of Reading in the UK asked 37 healthy volunteers to drink 500ml (about two cups) of orange juice a day for eight weeks.
brain function of participants (24 women and 13 men, all aged 60 to 81) improved significantly. The researchers measured their memory, brain response time and language fluency before and after the experiment, and each participant received a total score. Their score increased by 8%. In less than two months, this is a clear improvement.
researchers say they may not advise people to drink 500 milliliters of orange juice a day, and adding a certain amount of orange juice to their diet can improve brain health, saving money and convenience.
, author of the study and a researcher at the University of Reading's School of Psychology, said: "The global population is ageing rapidly. It is estimated that the number of people aged 60 and over could triple by 2100. Therefore, in improving cognitive function in the elderly, we must find a simple and cost-effective way.
Although many fruits and vegetables - as well as tea, cocoa and red wine - are known to contain flavonoids, citrus fruits contain flavanone, a type of flavonoid that is very beneficial to the body. "Flavanone is one of the easiest flavonoids to absorb," the study authors said.
previous studies have highlighted the potential effects of flavonoids, but this is the first time scientists have studied the role of flavonoids found in citrus fruits.
study was published in the American Journal of Clinical Nutrition.
