Canola is a specifically bred variety of rapeseed and is part of the mustard (or Brassica) family whose other members include broccoli, Brussels sprouts, cabbage, kale and mustard greens. Canola oil contains a fatty acid profile of: 5% saturated fat, 57% monounsaturated acid (oleic acid), 23% polyunsaturated omega-6 and 10â15% polyunsaturated omega-3. It is thought that its high oleic acid content (similar to levels found in olive oil), low saturated fat content and relatively high omega-3 content make canola oil particularly beneficial for heart health.
