Scientists Discover How Coffee Impacts Memory, Mood, and Gut Health

A study found that regular coffee changes gut microbes and metabolite activity, offering a biological link to digestion and brain health.

Both caffeinated and decaf coffee were associated with better mood and lower stress.

Decaf was linked to improved learning and memory, while caffeinated coffee was associated with less anxiety and sharper attention.

The findings suggest different coffee types may affect the gut-brain axis in distinct ways.
