Coffee Consumption Linked to Mood and Gut Microbiota Changes
A study found that both caffeinated and decaffeinated coffee consumption is associated with improved mood and changes in gut microbiota.

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.
