New research: regular tea drinking helps brain health

As we all know, drinking tea can refresh the mind, and the benefits of tea to the brain are more than that A new study finds that people who regularly drink tea tend to have healthier brain structures when they get older, helping to slow down cognitive decline An international research team led by the National University of Singapore recently published a paper in the American Journal of aging, saying that the components in tea can directly affect the connections between brain regions, and regular drinking of tea can help the brain resist age-related structural changes The team took 36 people over 60 years old as research objects, collected their physical state, lifestyle, mental health and other information between 2015 and 2018, and conducted neuropsychological tests and MRI on them By analyzing their cognitive performance and imaging results, the researchers found that people who drank tea at least four times a week for 25 years had more efficient connections between brain regions than those who did not drink tea, whether they drank green tea, oolong tea or black tea Taking road traffic as an example, when roads are well planned, vehicles and pedestrians will travel more efficiently, and when brain regions are better connected, the brain will process information more efficiently, the researchers explained The team found in 2017 that drinking tea every day reduced the risk of cognitive decline in old age by 50% This study further confirms this conclusion The researchers said that people who drink tea often avoid the interference of some ineffective connections in the brain, which can help slow down the decline of cognitive level The next step of the team is to study the relationship between the specific components of tea and cognitive ability, and explore possible interventions to protect cognitive ability in the process of aging.
