Regular coffee consumption, both caffeinated and decaffeinated, is linked to improved mood and significant changes in gut microbiota composition, highlighting coffee's broader impact beyond just caffeine.
Caffeinated coffee specifically reduces anxiety and enhances cognitive functions like vigilance and attention, while decaffeinated coffee improves learning, memory, and sleep, indicating distinct benefits from different coffee types.
The study reveals coffee's influence on the gut-brain axis through altered gut metabolites and specific bacterial species, suggesting a complex interplay between coffee, gut health, and mental well-being.

A recent study indicates that regular coffee consumption, including decaffeinated varieties, correlates with improved mood and altered gut microbiota composition. These changes were observed in both caffeinated and decaffeinated coffee drinkers.
The research identified associations between coffee intake and reduced stress, depression, and impulsivity. Caffeinated coffee specifically correlated with decreased anxiety and enhanced vigilance, attention, and blood pressure.
Decaffeinated coffee was linked to improvements in learning, memory, physical activity, and sleep. The study also noted changes in specific gut metabolites and bacterial species, such as Cryptobacterium curtum and *Eggertella sp.
CAG:209*, associated with coffee consumption.
These findings suggest coffee's influence extends beyond caffeine, impacting the gut-brain axis through its interaction with gut microbes and metabolism.
