New study suggests your daily coffee or tea habit helps fortify the brain against dementia
A major, long-term study published in JAMA found that moderate daily consumption of caffeinated coffee or tea is associated with a lower risk of dementia and slower cognitive decline.
The greatest benefits were observed at 2-3 cups of caffeinated coffee or 1-2 cups of tea per day, with no added protection from higher consumption.
Decaffeinated coffee showed no association with reduced dementia risk, strongly suggesting caffeine is the primary active ingredient responsible for the potential protective effect.
While not proving causation, scientists suggest caffeine may protect the brain by blocking adenosine receptors (linked to reduced amyloid plaque buildup) and by improving vascular health and insulin sensitivity.
The research is observational and shows a modest association, not direct causation. Caffeine is not advisable for everyone, and this habit should be viewed as just one component of a broader brain-healthy lifestyle.
