Tea slows down brain aging

According to a study led by scientists from the National University of Singapore, those who drink tea regularly have a lower risk of cognitive impairment with age. At the same time, the kind of tea does not matter.

The results of previous studies have shown that tea is very useful for health as a prevention of cardiovascular disease, and is also a good way to improve mood. In 2017, a team of scientists demonstrated that daily consumption of tea can reduce the risk of cognitive decline by 50%, however, the mechanisms underlying this effect remain unknown.

Experts continued to study the beneficial properties of tea. From 2015 to 2018, they collected health and lifestyle data from 36 volunteers aged 65 years and performed MRI scans of their brains.

They concluded that those participants who drank tea at least four times a week for 25 years had increased connectivity of some brain structures. The kind of tea, in this case, was not important: black tea, green tea and Oolong had the same effect.

The authors believe that better organization of brain structures makes it work more efficiently and reduces energy costs. They intend to continue to study and find out what biological substances have an impact on improving cognitive function.
