Canola oil comes from the seeds of the canola plant. Once harvested, canola seeds are crushed and the oil contained within the seed is extracted. The average canola seed is 45% oil.
Canola oil is heart-healthy. It has the least saturated fat of any common cooking oil. In fact, it has less than half the saturated fat of olive or soybean oil. The US Food and Drug Administration (FDA) authorized a qualified health claim for canola oil's ability to reduce the risk of heart disease when used in place of saturated fat.
