Why buy canola oil: Neutral flavor and a high smoke point—the point at which an oil literally begins to smoke—make canola an excellent choice for baking and sautéing. Smoke point is an important consideration if you’re planning to cook at high heat—as you do when you’re frying or grilling. At an oil’s smoke point, nutrients are destroyed and potentially health-harming compounds are formed. Canola oil generally doesn’t have many antioxidants, as olive oil does, but it does have a relatively long shelf life. In addition, canola is the richest cooking-oil source of alpha-linolenic acid, an omega-3 fat that has been linked to heart health.
