In the 1970s, in response to tighter restrictions on rapeseed oil, scientists in Canada used plant cross-breeding to create a crop called canola or Brassica napus L. — an edible type of the rapeseed plant. Rapeseed oil at the time contained high amounts of erucic acid – an omega-9 fatty acid associated with heart muscle damage in animal studies, and glucosinolates — antinutrients that prevent iodine absorption. The plant they developed had lower levels of erucic acid and glucosinolates. The term canola comes from ‘Canada’ and ‘ola’ for oil. Canola plant looks almost identical to the rapeseed plant, but it has different nutrients, and its oil is considered safe for human consumption.
