Three Cups of Green Tea Can Kill Dementia
Agra, Uttar Pradesh — 05th of October, 2025
Green tea has long been cherished in many cultures — but recent scientific research suggests something even more compelling: drinking three cups of green tea daily may help preserve brain health and reduce the risk of dementia-related changes.
A large-scale Japanese study involving 8,766 older adults without dementia found that those who drank three or more cups of green tea per day had about 3% fewer white matter lesions in their brains compared to those drinking just one cup. Participants who consumed seven to eight cups daily showed 6% fewer lesions. (White matter lesions are linked to cognitive decline, memory issues, and risk of Alzheimer’s disease.) alzinfo.org
Although the study did not find a measurable effect on brain volume (i.e. overall brain shrinkage), the association between higher green tea intake and fewer brain lesions remained even after adjusting for factors like age, gender, education, and physical activity.
What’s Behind the Benefit?
Green tea is rich in antioxidant compounds, particularly flavonols and EGCG (epigallocatechin gallate), which help protect cells (including brain cells) from oxidative stress and inflammation. These processes are implicated in age-related neurodegenerative changes.
Earlier research has also shown that higher flavonol intake is associated with lower risk of Alzheimer’s disease in later years, and that green tea’s antioxidants may support cardiovascular health, which is intimately tied to brain health.
Why we care?
For people in Agra and across Uttar Pradesh, this research underscores how simple dietary habits—like substituting regular tea or sugary drinks with green tea—may contribute to long-term brain wellness. While green tea isn’t a guarantee or cure, its consistent use could be a valuable, low-cost tool in nurturing cognitive health.
At Sensoriom, we believe in blending traditional wisdom with modern nutritional science. We encourage residents, especially those in urban and semi-urban communities like Agra, to explore dietary upgrades that are accessible, sustainable, and backed by evidence.
A Note of Caution & Practical Tips
The study is associational, not proof of direct causation. It points to a link, not a guarantee.
Individuals with certain medical conditions (e.g. sensitivity to caffeine, stomach acidity, iron absorption issues) should consult a health professional before increasing green tea consumption.
Start gradually: one cup a day, and monitor how your body responds.
To maximize absorption, consider having green tea in between meals rather than immediately after a heavy meal.
Opt for high-quality green tea leaves (loose leaf, minimally processed) to ensure better bioactive compound retention.
Sensoriom’s Mission: From Agra to All India
By sharing insights like the potential brain benefits of green tea, Sensoriom reinforces its commitment to nutritional awareness, community health education, and sustainable food practices. We aim to bring evidence-based knowledge into the everyday lives of people in Agra, Mathura, Bharatpur, and across the Hindi heartland.
