STUDY SHOWS THAT REGULAR TEA DRINKING BOOSTS BRAIN HEALTH
Posted on October 09 2019
A study by the National University of Singapore recently found that regular tea drinkers have better brain cognition. The participants aged 60 and above who took part in the study had an MRI and neuropsychological tests to see what affect tea may have had on their cognitive function.
They found that those who had drunk green tea, oolong or black tea at least 4 times per week for 25 years had better brain efficiency.
Assistant professor Feng Lei from the National University of Singapore explained in a EurekAlert press release, why connectivity is so important:
"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 organised, 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. 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 organisation brought about by preventing disruption to interregional connections."
“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,” he added.
The results were published in the scientific journal Aging.
Professor Feng also led a study in 2017of 957 Chinese seniors and found that regular consumption of tea lowers cognitive decline in the elderly by 50% and up to 86 percent for those who are genetically predisposed to the debilitating disease.
