That video starts out with saying that Canola oil is derived from the canola plant. But there is no canola plant.
The plant is actually called “rape”, and until Canada decided that rapeseed oil had a marketing problem that’s what it was called. Canola is an acronym for Canada Oil Low Acid. It’s a patented trademark owned by the Canadian Canola Council.
Canola oil has a high Omega 6 to Omega 3 ratio. I think that this is true of most seed oils, and that seems to be behind the claim that they are bad for you.
I don’t know if there is any proof that seed oils are actually harmful or if this is just another health food fad. It’s a recent obsession.
