How Coffee Helps Your Gut And Your Brain

A University College Cork study found that 3 to 5 cups of coffee a day was linked to more beneficial gut bacteria, lower inflammation, and better mood and cognition.

Caffeinated coffee was associated with less anxiety and improved attention, while decaffeinated coffee was linked to better sleep, activity, and memory.

Researchers say the benefits may work through the microbiota-gut-brain axis, with coffee’s polyphenols likely playing a role.

The findings suggest moderate coffee intake may support gut, immune, mood, and cognitive health beyond simply boosting alertness.
