> I was confused too... but in the US, the terms coconut tree, palm tree and coconut palm are used interchangeably.
You're still confused. Coconut tree and palm tree aren't interchangeable; to be a coconut tree, the tree has to grow coconuts. All palm trees count as "palm trees", whether they grow coconuts or not. The prototypical palm tree grows dates.
I’ve never seen palm kernel oil listed as a food ingredient. It seems to be most commonly used in cosmetics.
This is a mix up on why certain oils are on the current “oils to avoid” list. Palm oil gets a bad reputation mainly because of environmental issues with how it's grown, not because it's unhealthy. But all these concerns get lumped together in the “bad oils” list.
