Research has reported a significant connection between higher green tea consumption and fewer cerebral white matter lesions in older adults without dementia. Findings suggest that drinking three or more glasses of green tea daily may help protect brain health, while coffee consumption showed no significant effect.
Cerebral white matter lesions, often indicative of small vessel disease, have been associated with cognitive decline, vascular dementia, and Alzheimer's disease (AD).
Data collection occurred between 2016 and 2018, including dietary assessments, MRI scans, and cognitive evaluations of 8,766 participants aged 65 and older.
Brain MRI scans provided data on the volume of white matter lesions (WML), hippocampal volume (HV), and total brain volume (TBV). Advanced statistical models were applied to adjust for confounding factors, including demographics, health conditions, lifestyle habits, and genetic risk factors for Alzheimer's disease.
The analysis excluded participants with mild cognitive impairment (MCI), dementia, or incomplete data.
After adjusting for confounding factors, higher green tea consumption was significantly associated with lower WML volumes. Participants consuming 600 ml of green tea daily had WML volumes that were 3% lower than those consuming 200 ml or less, and those consuming 1,500 ml daily had WML volumes that were 6% lower than those in the reference group.
No significant associations were observed between green tea intake and hippocampal or total brain volumes. Coffee consumption did not significantly affect WML volume, HV, or TBV.
The study also examined subgroups based on depression status and the presence of the ApoE ε4 allele. Significant reductions in WML volumes with increased green tea consumption were observed only in individuals without depression or the ApoE ε4 allele.
Findings suggest that the antioxidant and anti-inflammatory properties of green tea catechins, such as epigallocatechin gallate, may mitigate vascular damage and promote brain health, though specific components were not experimentally validated.

It’s the combination of theophylline and EGCG which helps keep the capillaries open; most minor strokes are the result of capillary blockage more than the carotid artery. Matcha is more effective than brewed sencha, but if all you drink is green tea then your brain capillaries will thank you.
It's EGCG among other catachin compounds that provide such amazing health benefits.
For green tea drinkers, it's important to not brew green tea in too hot of water as the catachins activity can be degraded at higher temps.
Folks might also consider green tea extracts as supplements.
3 glasses of green tea a day? Yuk. Is there a pill for that?
Can we send green tea to our geriatric Congress, in 55 gallon drums?
You can obtain green tea supplements, as capsules or tinctures.
When I cook Chinese style foods, I do make a combo of hot jasmine green tea and Oolong tea, but otherwise, it would have to be supplements for me.
Oh great! Now I have to worry about having a deficiency of white matter lesions? WHITE MATTER LIVES MATTERS
Nice - and I like green tea.
Drinking good, aged Tequila burns those hated white spots right off.
3%. What was the accuracy of the measurement?
Extra thanks for this article, CM. I have been wondering for quite a while about which supplemental route to choose as more advantageous- EgCg or olive leaf extract, or something else, (Resveratrol/grapeseed extract) and this provides at least some idea.
I take 20% oleuropein olive leaf extract and green tea extract from time to time.
C.M. Thanks! Will up my intake of Green Tea and matcha!
