An everyday drink has been found to have significant benefits for brain health. This revelation comes from a comprehensive study conducted by Japanese researchers at the University of Tokyo. The focus of the study was green tea, a beverage believed by scientists to have the potential to reduce damage to the brain’s white matter, which is a crucial indicator of dementia risk.
The study involved 8,76 individuals aged 65 and above, with data collected between 2016 and 2018. The data was analyzed using magnetic resonance imaging. The findings revealed that participants who consumed three cups of green tea daily had, on average, 3% fewer brain injuries compared to those who only drank one cup. Furthermore, those who consumed between seven and eight cups daily experienced a 6% reduction in brain damage.
While the study does not establish a direct cause-and-effect relationship, the correlation between green tea consumption and reduced brain injuries remains significant. This is true even after adjusting for factors such as age, sex, physical activity, and education level. However, no effect was observed on hippocampal volume, and no beneficial effects were noted in individuals with depression or those genetically predisposed to Alzheimer’s disease.
The researchers suggest that the beneficial effects of green tea could be linked to its ability to lower blood pressure, unlike coffee, which can increase it. However, as the study was conducted exclusively on Japanese participants, further research is needed to confirm these findings in other populations. The daily consumption of green tea could become a key factor in maintaining brain health and preventing dementia.
