Singapore: Researchers have found that regular tea drinkers have better-organized brain regions, which is associated with healthy cognitive function compared to non-tea drinkers.

"Our results offer the first evidence of tea's positive contribution to brain structure and suggest that drinking tea regularly has a protective effect against the decline of aging-related brain organization," according to a study by Feng Lei, Assistant Professor at the National University of Singapore.

Previous researchers have demonstrated that tea consumption was beneficial to human health and its positive effects included improved mood and prevention of cardiovascular disease.

For the study published in Aging magazine, the research team recruited 36 adults aged 60 and over and collected data on their health, lifestyle and psychological well-being.

Elderly participants also had to undergo neuropsychological tests and magnetic resonance imaging (MRI).

The study was conducted from 2015 to 2018.

After analyzing the cognitive performance and imaging results of the participants, the research team found that people who consumed green tea, oolong tea or black tea at least four times a week for about 25 years had interconnected brain regions more effectively. .

"We have shown in our previous studies that tea drinkers had better cognitive function compared to non-tea drinkers," said Lei.

"Our current findings regarding the brain network indirectly corroborate our previous findings by showing that the positive effects of regular tea consumption are the result of better brain organization resulting from the prevention of disruption of interregional connections," he said. he added.
