Key Takeaways

  • Drink 2-3 cups of coffee daily for maximum dementia risk reduction (18-19% lower risk vs non-drinkers).
  • Choose caffeinated over decaf – decaf showed no protective effects in the study.
  • Finish caffeine intake within 4 hours of waking to avoid sleep disruption, even if you “feel fine”.
  • Use filtered coffee – unfiltered may raise LDL cholesterol.
  • Avoid adding sugar/cream – negates health benefits.

Bottom Line

Moderate caffeinated coffee consumption (2-3 cups before noon, black and filtered) may significantly reduce dementia risk based on long-term data – implement this simple habit if you tolerate caffeine well.
