- Researchers found that both caffeinated and decaffeinated coffee alter gut bacteria, linked to better mood and lower stress.
- Coffee consumption, defined as 3-5 cups daily, increased specific bacteria like 'Eggertella sp' and 'Cryptobacterium curtum', which may protect against harmful microbes.
- Decaffeinated coffee improved learning and memory, suggesting non-caffeine compounds like polyphenols contribute to cognitive benefits.
- Caffeinated coffee reduced anxiety and enhanced focus, attention, and alertness, while also lowering inflammation risk.
- The study highlights coffee's role in reshaping the gut microbiome and influencing the gut-brain axis, offering complementary health effects regardless of caffeine content.
