Rapeseed oil is rich in mono-unsaturated fats, and poly unsaturated fats as well as Omega 3, 6, 9 (essential fatty acids) which are all known to help lower cholesterol. Rapeseed also known as Canola oil is a great source of healthy fats and these EFA’s are from plant sources which is even better, and help to promote good cardiovascular health. Rapeseed oil also contains alpha-linolenic acid (ALA). It is important to find food sources containing these fats because the body doesn't naturally produce them. Rapeseed is now commonly used as  cooking oil.
