Coffee Consumption Linked to Lower Stroke Risk and Gut‑Brain Benefits

A Japanese cohort study of 83,269 adults followed for an average of 13 years found that drinking at least one cup of coffee daily was associated with roughly a 20% lower overall risk of stroke and up to a 32% reduction in hemorrhagic stroke compared with non‑drinkers.

An Irish study of 62 healthy adults aged 30‑50 examined the effect of coffee on the gut‑brain axis. Participants who consumed 3‑5 cups per day showed a distinct gut microbiota profile, altered microbial metabolites, and changes in mood, cognitive performance, immune markers and inflammation. These effects disappeared when coffee was stopped for two weeks and returned when coffee consumption resumed, indicating that both caffeine and polyphenols contribute to the observed benefits.

Together the research adds to existing evidence that moderate coffee intake can lower the risk of cardiovascular events, diabetes and stroke while also supporting gut‑brain health.
