Turns out your coffee addiction may be doing your brain a favor

A 43-year study by Mass General Brigham tracking over 130,000 participants found that moderate caffeinated coffee or tea consumption (2–3 cups daily) was associated with an 18% lower risk of dementia and better cognitive test scores. The researchers caution the findings are observational and cannot prove causation, though prior research points to plausible mechanisms like improved blood flow and reduced inflammation.
