Orange juice good for ageing brain: Study

Orange juice is a major source of flavonoids -- being particularly rich in a sub-class of flavonoids, known as flavanones.

This study is thought to be one of the first to show that regularly consuming orange juice flavanones could have a positive effect on older people's cognition.

"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 said.

"This is an important discovery which strengthens the growing body of evidence that flavonoid rich foodstuffs could play a big role in tackling cognition decline in old age," he concluded.
