How Green Tea Supports Brain Health and Fights Dementia

Ever wondered if your favorite cup of green tea could do more than just refresh you? According to a recent study (Shibata S, et.al., 2025), it might actually help protect your brain as you age.

Researchers in Japan examined the effects of green tea and coffee consumption on brain health among 8,766 people. They used brain scans to measure cerebral white matter lesions (a marker for brain aging and potential dementia risk), as well as hippocampal and total brain volumes.

Here's what they found:

• Green Tea Wins: People who drank more green tea had fewer cerebral white matter lesions. This is significant because fewer lesions could mean a lower risk of developing dementia. However, green tea didn’t show a noticeable impact on the size of the hippocampus (key for memory) or overall brain volume.

• Coffee? Not So Much: Surprisingly, coffee drinkers didn’t experience similar benefits. The study found no significant connection between coffee consumption and any of the brain health markers measured.

What Does This Mean for You?

If you’re looking for a simple lifestyle tweak to support brain health, reaching for a cup of green tea might be worth considering. If you don’t like the taste of green tea, you can take good quality green tea capsules. While more research is needed, these findings suggest that green tea could play a role in keeping your brain sharp and reducing dementia risks.

Next time you’re deciding on a drink, go green—it could be a small step toward a healthier future for your mind!
