Rapeseed has been grown for 4,000 years. The Romans burned it in lamps. Medieval Europeans used it for lamp oil. The industrial revolution used it to lubricate steam engines. It worked brilliantly: high heat tolerance, doesn't break down easily. Perfect for machinery. Toxic for humans.

The problem: Rapeseed contains 50% erucic acid. This compound causes heart lesions in animals. Feed it to rats, their hearts develop fatty deposits and scarring. It also contains glucosinolates that suppress thyroid function. Your body actively rejects it as poison.

They call it "Canola" - Canadian Oil Low Acid. Marketing genius. Same plant, different branding.😡
