Quick Summary
Your morning coffee or tea could be quietly supporting your brain health. A long-term study found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia and better cognitive performance over time. The benefits appeared strongest at 2–3 cups of coffee or 1–2 cups of tea daily—and even held true for people genetically predisposed to dementia.
