Regularly drinking green tea may help protect the brain from age-related damage, according to a recent large-scale study.
The research, which analyzed data from over 8,700 adults without dementia, found that green tea consumption is linked to fewer white matter lesions in the brain. These lesions are changes closely tied to cognitive decline, Alzheimer’s disease, and vascular dementia.
As people age, the brain undergoes structural changes. White matter lesions tend to accumulate over time, influenced by genetics, vascular health, and lifestyle habits. White matter is essential for efficient communication between brain regions.
The study reported that adults who drank about three cups of green tea daily had roughly 3 percent fewer lesions than those who drank less than one cup. Drinking six cups daily was associated with a 6 percent reduction in lesions.
Unlike green tea, coffee did not show measurable effects on white matter, hippocampal volume, or total brain size in the same analysis.
The protective effects are attributed to compounds in green tea, particularly catechins like epigallocatechin gallate (EGCG). These antioxidants and anti-inflammatory compounds help protect brain cells, reduce vascular damage, and support overall neural health.
To incorporate green tea into a brain-health routine, the study suggests drinking 3 to 6 cups daily to match the protective levels observed. Unsweetened or lightly brewed green tea maximizes antioxidant intake.
Pairing green tea with other healthy habits, such as regular movement, quality sleep, and nutrient-dense meals rich in omega-3s, colorful produce, and lean proteins, may amplify cognitive benefits.
Green tea offers a simple, science-backed way to support brain function over the long term. Each cup provides a daily boost for cognitive resilience, and when combined with healthy habits, these small rituals can contribute to lasting protection for the brain as it ages.
