Key Points:
- A long-term study published in JAMA found that people who drink caffeinated coffee and tea have an 18% lower risk of developing dementia compared to those who consume little or none, with the strongest benefits seen in those drinking two to three cups of coffee or one to two cups of tea daily.
- The research analyzed data from 131,821 participants over several decades, tracking their self-reported caffeine intake and cognitive health, but did not find a significant association between decaffeinated coffee and dementia risk.
- Experts, including Dr. Céline Gounder, caution that the study shows only an association, not causation, and that other factors like underlying health conditions could influence dementia risk; more research is needed to confirm these
