Canola oil has very high in healthier unsaturated fats. It contains higher in the omega-3 fatty acid alpha-linolenic acid (ALA) than any other oil except flaxseed oil.
The studies shows 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 may reduce risk of heart disease.
