In this case, the article is clearly a piece that's advocating coffee drinking. When research crosses over from "setting up and experiment and proving/ disproving a hypothesis" to "advocating something as good or not good in general", its important to look at the source of funding and apply a heavy discount on the validity of the research if its advocating "for the money". This is not research "related" to coffee, so your hypothesis is not valid in this instance.
