Canola oil is one of the healthiest cooking oils available, with zero trans fat and the lowest amount of saturated fat of all common cooking oils. And because canola oil is so versatile and affordable, it’s ideal for making a wide range of healthy foods, both at home and on a commercial scale. Canola oil comes from the seeds of the canola plant, one of the most widely grown crops in Canada. After harvesting, canola seeds are crushed to release the canola oil.
