Long term, moderate, coffee consumption might lower dementia risk
7 April 2026
Carly Page, writing for The Register:
Researchers from Mass General Brigham tracked more than 130,000 people for over four decades and found that those who regularly consumed moderate amounts of caffeinated coffee or tea had an 18 percent lower risk of developing dementia compared to those who rarely touched the stuff.
The thing is coffee consumption has to be consistent — spread across decades — and in moderation. Two, maybe three, cups per day. But caffeine seems to be the active ingredient, not coffee per se.
Drinkers of teas with higher caffeine levels might also enjoy the same benefits. Matcha, and black tea, are among tea beverages high in caffeine.
