A recent study conducted by researchers from Harvard University has found that daily consumption of tea and coffee is associated with a lower risk of dementia. The strongest protective effects were observed among individuals who consumed two to three cups of caffeinated coffee daily, showing an 18% reduction in dementia risk compared to those with lower intake. Similarly, participants who drank one to two cups of tea daily experienced a 16% reduced risk of developing dementia.

The findings, published in the Journal of the American Medical Association (JAMA), also indicate that higher consumption of both beverages is linked to a slower rate of cognitive decline. This highlights how regular intake of caffeinated drinks like coffee and tea could play a significant role in maintaining brain health as individuals age. However, the study noted no such benefits associated with decaffeinated coffee, suggesting that caffeine may be a crucial factor in these protective effects.

Overall, the implications of this research are notable, suggesting that moderate caffeine consumption might serve as a preventive strategy against cognitive decline and dementia. These findings could influence dietary recommendations for older adults as medical professionals seek ways to promote better brain health among aging populations.
