How many cups of coffee should you drink daily? Study reveals the beverage's impact
A recent scientific study has once again placed coffee at the center of conversations about brain health and lifestyle habits. The research, published in JAMA and conducted by experts from Harvard School of Public Health and Mass General Brigham, followed over 131,000 people for up to 43 years to identify any relationship between daily coffee consumption and the risk of developing dementia over time.

TL;DR
- Consuming 2-3 cups of caffeinated coffee daily is associated with a reduced risk of dementia.
- A study of over 131,000 people tracked for up to 43 years found an 18% lower risk of dementia in moderate coffee drinkers.
- The benefits appear specific to caffeinated coffee; decaffeinated coffee showed no clear association with lower dementia risk.
- Compounds like caffeine and polyphenols in coffee may offer anti-inflammatory and protective effects on brain cells.
- Optimal daily intake for cognitive health appears to be 2-3 cups, emphasizing moderation and consistency over excess.
