Note that this article is talking about "coffee", not "caffeine". Many of the benefits can be had from decaf. As I understand coffee is one of the major sources of antioxidants in standard American diets which is probably a big reason for this.
The article also states:
> People often equate coffee with caffeine, but coffee beans actually have over 100 biologically active compounds. These substances can help reduce oxidative stress and inflammation, improve insulin sensitivity, boost metabolism, inhibit the gut’s absorption of fat and block receptors known to be involved with abnormal heart rhythms.
"The most-common methods of decaffeination involve chemical solvents, usually ethyl acetate or methylene chloride. In the direct method, the coffee beans are steamed and then rinsed repeatedly with the chemical solvent to flush away the caffeine."[0]
It is not a given that the coffee doesn't have extra unhealthy chemicals or is stripped away of vital nutrients besides caffeine.

and...?
The problem with a statement like this is that their have been decades of studies with normal coffee while there have been far fewer with decaf.
