Vegetable oils are oils extracted from seeds, nuts, and fruits of plants and are used in many applications such as cooking, cosmetics, and other industries. Among the most commonly used vegetable oils are olive oil, corn oil, soybean oil, cottonseed oil, coconut oil, and canola oil. Vegetable oils differ from one another in terms of their physical and chemical properties and uses, and some contain high levels of healthy fatty acids, vitamins, and antioxidants.
