Vegetable Oil: Important Facts, Health Benefits, and Recipes

Vegetable oil is a category of commonly used cooking oils derived from various plant sources and preferred for the high smoke point, versatility, and mild flavor.

What is Vegetable Oil?

Vegetable oil is a general term for oil that is extracted from fruits, seeds, grains, and nuts - basically anything plant-based.  The top four vegetable oils consumed in the United States are soybean, canola, palm, and corn oil.  Some other vegetable oils are: coconut, cottonseed, olive, peanut, safflower, and sunflower. Vegetable oils are often used because of their neutral flavor, like in baking or frying. In addition, because vegetable oils are plant-based they are lower in saturated fat.

Is Vegetable Oil Good For You?

That is up for debate. Vegetable oil is sometimes seen as a healthier option versus butter because it typically is lower in saturated fat. But depending on the type of oil (canola, olive oil, grapeseed oil, etc.), the health benefits and impact vary. Many oils have been processed and treated with hexane to extract more oil from the vegetable, which some people say can be bad for health. Most vegetable oils are high in omega-6 fatty acids (linoleic acid), which some studies claim cause inflammation.

5 Benefits of Vegetable Oil

  1. Vegetable oils are low in saturated fats
  2. Vegetable oils are plant-based and therefore have no cholesterol
  3. Most vegetable oils are high in omega-6 fatty acid (linoleic acid), a polyunsaturated fat. We need omega-6 for brain function, skin and hair growth, bone health, and metabolism. But consuming too much can be harmful to our health.
  4. Some research says that the plant sterols in soybean oil may lower LDL cholesterol levels
  5. Some vegetable oils (olive and avocado) are a good source of monounsaturated fats, which can be heart healthy

History, Background, and General Facts about Vegetable Oil

  • The top four vegetable oils consumed in the United States are soybean, canola, palm, and corn oil. 
  • Some other vegetable oils are: coconut, cottonseed, olive, peanut, safflower, and sunflower. 
  • Vegetable oil is often used because it has a neutral flavor, like in baking or frying.
  • The problem with this type of generic oil is that you often don’t know what it is made from and how it is processed. 
  • Most vegetable oils are high in omega-6 fatty acid, a polyunsaturated fat. We need omega-6 for brain function, skin and hair growth, bone health, and metabolism
  • Health-conscious consumers prefer oils that are made by crushing or pressing plants or seeds, rather than those produced using chemicals.

What Are The Cuisines That Regularly Include Vegetable Oil?

  • Chinese - fried rice, dumplings, donuts
  • Korean - fried chicken
  • Southern US - fried chicken, fried okra, fried cabbage
  • Myanmar (formerly Burma) - fried noodles
  • Italian - donuts (Ciambelle al Mosto)
  • Mexican - flautas, sope, taquitos

  • Vietnamese - fried tofu and fish
  • North America - French fries, beignets, fried chicken, donuts, fair food (fried candy bars and fried butter)
  • Chilean - sopaipillas
  • Spain - churros

What Is The Best Way To Store Vegetable Oil?

Store vegetable oil in a cool, dark place away from heat (including away from stoves or cabinets above or near stoves) like a pantry. Avoid buying large batches unless you will be using them right away. Vegetable oils go rancid quickly, so better to buy small batches.

If the oil is in a clear bottle and you don’t plan on using it quickly, wrap it in plastic or foil to keep light out or put it in the refrigerator.

What is the Difference Between Vegetable Oil and Canola Oil?

Vegetable oil and canola oil are both commonly used cooking oils, but there are some differences between them. Here's a breakdown of their distinctions:

  1. Source and Processing:
  • Vegetable oil: "Vegetable oil" is a broad term that refers to any oil derived from plant sources. It can be made from a variety of plants, including soybeans, corn, sunflower seeds, safflower seeds, and more. The specific composition of vegetable oil can vary depending on the plants used and the processing methods employed.
  • Canola oil: Canola oil is a type of vegetable oil that is specifically derived from the seeds of the canola plant, which is a cultivar of the rapeseed plant. Canola oil is produced by crushing the seeds and extracting the oil. It is then refined to remove impurities and undergoes processing to achieve a neutral flavor and higher smoke point.
  1. Flavor and Smoke Point:
  • Vegetable oil: Vegetable oils can have varying flavors and smoke points depending on their source. They can have a neutral flavor or a mild taste derived from the plant they are made from. The smoke point can also vary, but it is generally higher than that of butter or olive oil, making vegetable oil suitable for a range of cooking methods.
  • Canola oil: Canola oil has a mild and neutral flavor, making it versatile and suitable for a wide range of cooking applications. It has a relatively high smoke point, typically around 400°F (204°C), which makes it ideal for frying, baking, sautéing, and other high-heat cooking methods.
  1. Nutritional Profile:
  • Vegetable oil: The nutritional composition of vegetable oil can vary depending on the specific plant sources used. Generally, vegetable oils are low in saturated fats and cholesterol-free. They are a source of polyunsaturated and monounsaturated fats, which are considered more heart-healthy.
  • Canola oil: Canola oil is known for its heart-healthy profile. It is low in saturated fats and contains a good balance of omega-3 and omega-6 fatty acids. Canola oil also has a relatively high content of monounsaturated fats, similar to olive oil.

When choosing between vegetable oil and canola oil, it often comes down to personal preference, the desired flavor, and the cooking method being used. Both oils can be used interchangeably in many recipes, but canola oil's mild flavor and higher smoke point make it a popular choice for many home cooks and professional chefs.
