Canola oil is also very high in healthier unsaturated fats. It's higher in the omega-3 fatty acid alpha-linolenic acid (ALA) than any other oil except flaxseed oil. ALA is particularly important to have in your diet because your body can't make it. Studies show that ALA may help protect the heart through its effects on blood pressure, cholesterol, and inflammation. The FDA allows canola oil makers to label their products with a qualified health claim that there’s "limited and not conclusive" scientific evidence that switching out saturated fat for the same amount of canola oil may reduce risk of heart disease.
