I didn't see any evidence pointing a smoking gun at "good fats." For instance, the indictment of milk skirts the issue of organic vs. not, whole vs. 2% vs. 1% vs. skim milk, etc. That greater consumption of beef, pork and lunch meat (all requiring a lot of energy to chew and digest) were implicated in progression makes a fair amount of sense, so that's more of what I would take from it. (That said, an occasional cheeseburger IMHO never did anyone any harm.)
But like all studies relying on self-reported diet, there's a grain of salt involved. I see the message of the combined studies so far as eating a variety of minimally processed foods, and I also see considerable justification for putting real food into feeding tubes, as opposed to corn-syrup-based formulas.
Coconut oil is a specific chain type, so I wouldn't be using that as my only fat, but I wouldn't rush to jettison it as part of the fat portfolio, if it seems to help.
