Regular Tea Drinkers Cognitively Healthier?

Updated: Mar 3


A recent study from Yong Loo Lin School of Medicine at the National University of Singapore shows that daily consumption of tea can reduce the risk of cognitive decline in older persons by 50%. As quoted by Yong Loo Lon School of Medicine at the National University of Singapore, “Our results offer the first evidence of positive contribution of tea drinking to brain structure, and suggest that drinking tea regularly has a protective effect against age-related decline in brain organization,”.


The participants that consumed either green tea, oolong tea, or black tea at least 4 times a week for about 25 years had brain regions that were interconnected in a more efficient way. “Take the analogy of road traffic as an example—consider brain regions as destinations, while the connections between brain regions are roads. When a road system is better organized, the movement of vehicles and passengers is more efficient and uses less resources. Similarly, when the connections between brain regions are more structured, information processing can be performed more efficiently,” explains Feng.


“We have shown in our previous studies that tea drinkers had better cognitive function as compared to non-tea drinkers. Our current results relating to brain network indirectly support our previous findings by showing that the positive effects of regular tea drinking are the result of improved brain organization brought about by preventing disruption to interregional connections,” he says.


Cognitive performance and brain organization are intricately related, more research is needed to better understand how functions like memory emerge from brain circuits, and the possible interventions to better preserve cognition during the aging process. Feng and his team plan to examine the effects of tea as well as the bioactive compounds in tea can have on cognitive decline.
