They talk about other sources, and yes those are bad, but coconut oil is not and it has been proven.
"Populations That Eat a LOT of Coconut Are Healthy
Coconuts
If coconut fat were bad for you, then we should see some very sick people in populations that eat a lot of it.But we don’t. Populations who eat a large percentage of calories from coconuts are MUCH healthier than Western nations.The Tokelauans ate more than 50% of calories as coconut and were the biggest consumers of saturated fat in the world. The Kitavans ate up to 17% of calories as saturated fat, mostly from coconut."
See entire article @ Authority Nutrition (they give a lot of false information on this site, and although this article is not entirely correct, it has the correct information about Coconut oil)
