2.5 Studies on the side-effects of caffeine.

OAKLAND, California (UPI) -- Coffee may be good for life. A major study has found fewer suicides among coffee drinkers than those who abstained from the hot black brew.

The study of nearly 130,000 Northern California residents and the records of 4,500 who have died looked at the effects of coffee and tea on mortality.

Cardiologist Arthur Klatsky said of the surprising results, ``This is not a fluke finding because our study was very large, involved a multiracial population, men, women, and examined closely numerous factors related to mortality such as alcohol consumption and smoking.''

The unique survey also found no link between coffee consumption and death risk. And it confirmed a ``weak'' connection of coffee or tea to heart attack risk -- but not to other cardiovascular conditions such as stroke.

The study was conducted by the health maintenance organization Kaiser Permanente and was reported Wednesday in the Annals of Epidemiology.
