Excess Coffee May Be Linked To Early Death

Mr.Intel writes "Should we believe it? Those of us under 55 who drink a lot of coffee – more than four cups per day – may be at greater risk of an early death. And not just death from heart problems, but death from all causes. The study, published in Mayo Clinic Proceedings (abstract), followed people for almost two decades, and found that in both sexes, younger people were more likely to die of anything than people who drank less."

      Could be stress, but then you would expect the extra deaths would be mostly due to heart problems, which they didn't see. I'll hazard a guess that it has to do with liver function. It could just be if your liver is constantly busy breaking down caffeine it neglects some of its other duties. It could be that constantly breaking down caffeine changes the expression level of the enzymes that break down caffeine (like CYP1A2), and that is what causes problems. Or it could just be that caffeine is revealing a pre-existing problem: People who can't metabolize caffeine very quickly generally don't drink 28+ cups of coffee per week. They also tend to have different versions of CYP1A2 compared to people who metabolize caffeine quickly. So maybe the CYP1A2 alleles that are efficient at processing caffeine are lousy at some other more important task.
