Coffee intake linked to lower suicide risk

Observational data from 200,000 people enrolled in the Health Professionals Follow-up Study and the Nurse’s Health Study I and II showed that drinking two to three cups of coffee a day was associated with a 45% lower risk of suicide, and drinking more than four cups with a 53% reduced risk, compared with drinking less than one cup of coffee a week.

Decaffeinated coffee or tea consumption was not associated with suicide risk.

And the link between coffee and suicide was unchanged by smoking status or alcohol use.
