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.”
I tend to be quite suspicious of any study that contends any single factor increases risk of death from “all causes.”
At best, it might involve some sort of mildly interesting correlation, but it says nothing about either the factor (in this case, coffee) or its connection to such a massive spectrum of death.
