Myth 3: Canola oil is made from rapeseed plants, which are toxic.
Fact: Canola oil comes from the crushed seeds of canola plants — not rapeseed plants, which are, in fact, harmful. Rapeseed oil contains high levels of erucic acid, which is linked to heart disease and therefore is not allowed to be sold in the US. While the two plants are cousins, they're distinctly different in their composition. In the 1960s, farmers used breeding methods to help eliminate the erucic acid from canola plants, and canola oil is now regulated to contain negligible amounts of the compound, ensuring that canola oil is 100 percent safe. In fact, it also happens to be one of the healthiest oils (behind olive oil) because it has less saturated fat and more heart-protective omega-3s than other vegetable oils. Canola oil is just seven percent saturated fat compared to olive oil, which is 15 percent saturated fat.
