I don't know what time-tested means but mustard oil is banned in EU/US for edible uses due to high erucic acid. So you parents were right!

Seams not all mustard oil is Banned in the EU.

I've got a bottle of Uncle Roy's cold pressed extra virgin "spicy" mustard seed oil at my local Spar.

The label reads "erucic acid free", so I'm guessing they somehow remove it?

It even has the awful pun of "The healthy Oilternative".

I understand they also remove (most of?) it from Canola Oil.

Thanks for letting me know, I'll try to get my hands on it.

Mustard oil has been used in the subcontinent since the Indus valley civilization 4,500 years ago. It’s extremely well understood. Unlike solvent extraction of oil.

You write this as if there isn't controversy about mustard oil, which is banned in the United States because it contains high levels of a likely heart toxin ("Among South Asians living in the US, ASCVD risk is four-fold higher than the local population") and limited throughout Europe. The entire point of solvent extraction is convert rapeseed oil, which would otherwise be similarly problematic (they're basically the same plant!) into something less toxic than mustard oil (that's literally why it's called "canola").

I don't care either way; let the mustard oil flow. I don't buy the mustard oil thing either. Just don't pretend that mustard oil is somehow healthier than canola. Use whichever fat tastes best to you.

Canola oil is simply a mustard-seed oil from a hybrid mustard bred for low erucic acid content. Solvent extraction is widely used, but not something that defines canola oil. Cold-pressed and expeller-pressed canola oil are also produced on a smaller scale.

No, in populations which traditionally use mustard oil heart problems are common. So it's time tested to cause heart failure.
