Caffeine
I don’t drink coffee. I don’t really like the stuff (although I really like coffee flavored ice cream), the acid rips my stomach apart, and the caffeine makes me jumpy. One cup in the morning will give me a miserable day and a sleepless night. The New York Times offers details here (link courtesy of Tom Smith at The Right Coast), and a researcher at the National University of Ireland, Galway says “Lifelong use could account for 10 to 20 per cent of cardiovascular mortality”.
But note this. The researcher, Jack James, is coordinator of the EU-funded Caffeine and Health in Europe project. Did you think it would stop at tobacco and booze and fast food? Hah.
