Pint of Orange Juice a Day Improves Brain Function in Elderly: Study

Drinking orange juice every day could help improve thinking in people 60 years of age and older, according to the U.K.'s University of Reading.

Researchers enrolled healthy older adults (mean age of 67 years) and tested their memory, reaction time, and verbal fluency. The results were combined into an overall score known as "global cognitive function."

Participants were divided into two groups. One group drank 500 ml (just under a pint) of orange juice a day for eight weeks. A second group was given a control drink matched for taste and calories. At the end of the trial, all participants underwent cognitive testing for a second time.

Volunteers who drank orange juice showed an 8 percent overall improvement in cognitive function when compared to the control group. While the improvement was small, researchers say it was significant, and was the equivalent of remembering one more item on a 15 item shopping list.

This amount of improvement over a short eight-week period could translate into substantial improvements over a lifetime.

While the researchers aren't recommending that people begin drinking orange juice every day, they believe that the study shows that the brain-boosting nutrients found in orange juice are an important part of a healthy balanced diet.

Orange juice contains generous amounts of phytochemicals called flavonoids. Recent studies show that they may improve memory by stimulating the hippocampus, a part of the brain linked with learning and memory.

"The population is aging rapidly across the world. Estimates suggest that the number of persons aged 60 or over could triple by 2100," said Dr Daniel Lamport of the University of Reading. "It's therefore imperative that we explore simple, cost-effective ways to improve cognitive function in old age.

"Small, easily administered changes to the daily diet, such as eating more flavonoid-rich fruits and vegetables, have the potential to substantially benefit brain health," Lamport continued. "We know that people find it difficult to sustain big changes to their diet but simple alterations are much easier to maintain permanently."
