☕➡️🧠 From Coffee Cup to Cerebral Cortex

☕🧠 Can your daily coffee protect your brain? In a JAMA study of 131,821 adults followed for up to 43 years, moderate caffeinated coffee and tea intake was associated with a lower risk of dementia and modestly better cognition. The sweet spot: 2–3 cups of coffee or 1–2 cups of tea per day. Notably, decaffeinated coffee showed no benefit. A compelling population-level prevention signal—simple habits, long horizons, meaningful impact.
