Coffee has positive impacts to your gut health — even when it’s decaf

Coffee, whether caffeinated or decaf, may support gut health and mood, based on Irish researchers' findings and the new reference.
Regular coffee consumers showed higher levels of certain gut bacteria linked to better health, aligning with the idea that habitual intake supports a healthier microbiome.
Decaffeinated coffee was associated with notable improvements in learning and memory, suggesting non-caffeine components drive cognitive benefits.
The study tracked 62 participants over two years, including a two-week coffee abstinence period, to assess gut-brain axis effects.
Coffee’s benefits extend beyond caffeine, including polyphenols that may reduce brain inflammation and support mood.
Caffeine itself may reduce inflammation, while decaf’s cognitive benefits point to non-caffeine compounds like polyphenols.
Researchers emphasize the gut–brain axis as a key area for understanding how coffee affects mood, stress, and cognitive function.
Experts suggest coffee could be part of a healthy, balanced diet to support gut and brain health, not just a caffeine hit.
The article notes coffee’s potential role in reducing dementia risk, slowing aging, and lowering death risk in line with broader coffee research.
The research team includes APC Microbiome Ireland at University College Cork, led by Professor Cryan, and they conducted a two-year study with coffee drinkers and non-drinkers.
