Palm oil is a vegetable oil. The production of vegetable oil (read: palm oil) creates an end product that looks and feels like oil, but has all kinds of other bad shit in it. It gets refined, heated, bleached, heated, deoderized, etc...
The same thing happens to flour. We process the living shit out of it, then bleach it, then we have to add-in all the stuff we removed so that it still has some semblance of nutrition.
It's like the deep fried pickle. A pickle in and of itself is a pickle, but when you deep fry it, is it still a pickle? Some will argue yes. Does it still have the same general health characteristics, or more importantly, the lack of negative characteristics as the deep-fried one? No.
