A recent study from Japan has revealed a significant link between daily green tea consumption and a reduction in brain lesions associated with an increased risk of dementia. The research, which analyzed data from 8,766 volunteers aged 65 and older, highlights the potential cognitive benefits of incorporating green tea into one’s diet.
The study, conducted between 2016 and 2018, examined self-reported consumption of green tea and coffee alongside MRI brain scans to assess brain volume and other features across five regions of the brain. Researchers found a notable correlation: participants who consumed three cups of green tea daily had three percent fewer white matter lesions, while those drinking seven to eight cups a day exhibited a six percent reduction compared to individuals who consumed just one cup.
White matter lesions are small abnormalities in the brain that can disrupt cognitive function and are linked to a higher risk of dementia. Although the study establishes a strong association between higher green tea intake and fewer brain lesions, it does not confirm a direct causal relationship. The researchers noted that coffee consumption did not show the same association with brain health.
Green tea is rich in antioxidant compounds known as catechins, which are believed to reduce inflammation and oxidative stress, both of which are related to neurodegenerative diseases. Furthermore, the lower caffeine content in green tea compared to coffee may contribute to better cardiovascular health, which previous studies have linked to reduced dementia risk.
While the findings are promising, the study does have limitations. It did not observe any significant effects of green tea on hippocampal or total brain volume, nor did it impact individuals with diagnosed depression or those carrying the APOE4 gene, a strong indicator of Alzheimer’s disease. Additionally, the study’s participants were exclusively Japanese, which raises questions about the applicability of the results to more diverse populations.
Researchers emphasize the need for further studies to confirm these findings and explore the effects of green tea across different demographics. Despite these limitations, the study suggests that increasing green tea consumption, particularly to three or more cups per day, may be beneficial for brain health and could help prevent dementia.
As research continues, individuals may consider adding an extra cup of green tea to their daily routine to potentially harness its health benefits, which also include advantages for weight management, heart health, and cancer prevention.
