Unfortunately, this is the kind of thing that only applies to regular coffee drinkers.
I'm probably the exception here, but my coffee consumption is limited to one espresso a day. I will sometimes have two, but any more and it begins to affect my sleep, and therefore my recovery. It also can make me jittery, and therefore less productive. Still maintaining a 45-60hr work week, and a 8-12hr training week.
My point is that coffee has negative "side-effects" associated with it don't allow it to be easily adopted. It isn't as easy as say reducing sugar consumption, or increasing the amount of green vegetables you eat.
Coming from a family that has a history of diabetes (on my maternal side), and heart disease (on my paternal side), I'd absolutely love to harness the benefits of coffee for those reasons, but I can't!
From the article...
"While decaf doesn't confer ALL the health benefits of the high-test, it's confers most of them. And with craft roasteries proliferating through the civilized parts of America, it's pretty easy to get super-high-quality decaf. So there's no reason to spend the rest of your (probably now longer) life suffering from the caffeine jitters."
