Your Morning Brew Could Protect Your Brain
30 May
Summary
- Drinking 2-3 cups of coffee or 1-2 cups of tea daily associated with lower dementia risk.
- Higher intake of caffeinated coffee linked to reduced cognitive decline and better performance.
- Decaffeinated coffee and tea showed no association with cognitive health benefits.
A significant long-term study has revealed a strong association between moderate daily consumption of caffeinated coffee and tea and a reduced risk of dementia. The research, which followed over 131,000 participants, indicated that individuals drinking 2 to 3 cups of caffeinated coffee or 1 to 2 cups of tea daily experienced the most notable benefits.
Participants with the highest intake of caffeinated coffee showed an 18% lower risk of developing dementia compared to those with the lowest intake. Similar positive cognitive outcomes, including better objective performance, were observed with higher caffeinated tea consumption.
Crucially, the study found no such association with decaffeinated coffee, suggesting caffeine plays a role. However, experts stress that these beverages are not a sole solution, recommending a holistic approach to brain health that includes a balanced diet, regular exercise, and adequate sleep.
Researchers also noted that it is challenging to isolate the effects of caffeine from other compounds present in coffee and tea, which may act synergistically. The findings align with broader research highlighting the importance of lifestyle factors in maintaining cognitive function.
