Green Tea May Protect Aging Brain: Study
Tokyo, 15 Jan (ONA) --- A study by Kanazawa University has linked daily green tea consumption to reduced white matter lesions in older adults without dementia.
Research conducted by the university’s Graduate School of Medical Sciences reveals that drinking three or more glasses of green tea daily may benefit brain health. The study found that higher green tea intake is associated with fewer cerebral white matter lesions—brain changes connected to cognitive decline and Alzheimer’s disease.
The findings, part of the Japan Prospective Studies Collaboration for Ageing and Dementia, analyzed MRI data to explore the effects of green tea and coffee on brain structure, including white matter lesions, hippocampal volume, and total brain size. Although both beverages are known for their neuroprotective properties, coffee showed no significant effect in this study.
Published in npj Science of Food, the research highlights a strong link between regular green tea consumption and reduced white matter lesions in older adults without dementia, even after adjusting for other factors.
"Our findings indicate that drinking green tea, especially three or more glasses per day, may help prevent dementia," the researchers stated. However, they stressed the need for further longitudinal studies and basic research to validate these results.
The study suggests that green tea could be an easy and accessible way to support cognitive health in aging populations.
