Canola Oil vs Vegetable Oil: Which is Healthier?

By Dr. Nikita Toshi +2 more

Key Highlights:

  • Both canola and vegetable oil are commonly used in cooking, each with its own set of nutritional values and health benefits.
  • While canola oil is considered healthier due to its lower saturated fat content, vegetable oil blends may vary, influencing the quality and quantity of specific nutrients.
  • The choice between the two extends beyond nutritional profiles as their cooking properties, such as smoke point, flavour, and shelf life, also matter.
  • Several other types of oils like avocado oil, extra virgin olive oil, grapeseed oil, MCT oil, peanut oil, and sesame oil also possess health benefits worth considering.
  • Proper storage of these cooking oils is crucial to ensure their longevity and quality.

Introduction

Ever find it hard to make a choice when faced with loads of cooking oils on the supermarket shelf? You know, staring at labels from canola to vegetable. Wondering which to pick? What factors should you consider? Health gains? Cooking needs? Fret no more! We’re here to simplify those tricky, oily choices.


This article will guide you. We’ll focus on two popular picks – Canola and Vegetable oils. With this guide, you’ll face the oil aisle with ease.

Understanding Canola oil

Canola oil is a common name in many homes. You see it used in almost all kinds of cooking. But what exactly is it? Why the widespread use?

What is Canola oil?

Canola oil is made from a plant known as ‘rapeseed.’ The seeds are crushed to get the oil. Most Canola plants are genetically modified for harvest and resistance to disease. But this raises issues about safety and potential sensitivity to chemicals used in its growth.

Nutritional values of Canola oil

Canola oil is loved for its healthy nutrient balance. It has low bad fats and high good fats. These good fats can help keep cholesterol levels in check and reduce heart disease risk.

Health benefits of using Canola oil

Canola has health benefits despite concerns about GMOs.

Role in heart diseases and cholesterol

It’s got low bad fat content. Bad fats are linked with high blood cholesterol levels. So, Canola oil can help maintain a healthy heart. Regular use could lower heart disease risks.

Did you Know?

  • Canola oil improves insulin sensitivity compared to other dietary fat sources. source: PMC
  • In 2022, the United States imported vegetable oils worth $10.9 billion, driven by increased demand for biodiesel and renewable diesel. source: USDA
  • Vegetable oil is a processed food product fortified with vitamins A and D for food aid purposes. source: USAID
  • Vegetable oil aids in the absorption of fat-soluble vitamins and helps increase the caloric density of diets. source: USAID

Based on what I have seen, canola oil is known for its high content of heart-healthy monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs), such as oleic acid, linoleic acid, and alpha-linolenic acid (ALA). It also contains plant sterols and tocopherols, which have been shown to have cardioprotective properties.

Cooking with Canola oil

Canola oil is a favourite in many kitchens because of its versatility.

Canola oil in frying, baking, and sautéing

Due to its high heat tolerance and neutral taste, it fits into any form of cooking. From baking your beloved muffins to frying foods or sautéing vegetables.

Effect on taste and texture

Despite being low in artery-blocking fats, Canola oil does not alter the outcome of your cooking. It adds a mild crispy feel when used to fry and protects the taste of your ingredients.

Over the years, I have learned that vegetable oil is a source of edible fatty acids (saturated, monounsaturated, and polyunsaturated) that play a crucial role in cellular metabolism. These fatty acids serve as a way to store and provide energy for the body when needed. Additionally, they are essential for cell division and growth, contributing to better physical health.

Exploring Vegetable oil

Now, let’s look at another common choice in kitchens – the vague “vegetable oil.” How does it compare?

What is Vegetable oil?

“Vegetable oil” is a generic term. It’s oil taken from plants. It could be a mix of sunflower, corn, soy, safflower, or even canola oil. Specific blends may not be revealed, which can blur the known nutritional benefit.

Nutritional values of Vegetable oil

The nutritional values in Vegetable oils aren’t fixed. They hinge on the unique blend. This affects the amount of helpful nutrients like vitamins. But, they usually contain more saturation than Canola oil.

Health benefits of using Vegetable oil

The upsides of Vegetable oils are all about their mix. Some oils like Soy and Corn bring omega-6 fats into your meals. However, too much could imbalance the body’s omega-3 to omega-6 ratio. This could cause inflammation, among other health issues.

Role in heart diseases and cholesterol

Vegetable oils do have heart-friendly unsaturated fats. But, their often-high saturation might add some risk to heart health. This is particularly true if you use them a lot in your meals without enough omega-3-rich foods.

Cooking with Vegetable oil

Vegetable oils serve many purposes in the kitchen because they’re flexible.

Vegetable oil in frying, baking, sautéing

Vegetable oils hold up well in several forms of cooking like Canola oil. They have high heat tolerance, and their taste doesn’t affect the food you’re cooking.

Effect on taste and texture

Like Canola, Vegetable oil doesn’t change the taste of your food. It does give a light crunch to fried foods though.

Comparison: Canola Oil vs Vegetable Oil

Now, let’s compare these oils. What’s similar and what’s different?

1. Nutrition profile comparison

On paper, they’re different. They both carry healthy unsaturated fats. Yet, Canola oil wins the balance game with its lower saturation and high monounsaturated fats.

2. Fatty Acid composition

Canola oil does well with its high level of heart-friendly fats. This gives it a slight advantage over most blended Vegetable oils. These fats can improve cholesterol levels and lessen heart disease risk when eaten with control.

3. Vitamin and Mineral content

Vegetable oils can be uncertain about vitamins and minerals because of differing oil blends. Canola oil, on the other hand, clearly contains vitamin E and vitamin K.

Cooking properties comparison

Both oils are great for high-heat cooking.

1. Smoke Point

Because Canola oil is full of heat-stable fats, it could be a little better than Vegetable oil. But generally, both oils can stand high heat with ease.

2. Flavour

Neither Canola nor Vegetable oil overpower the taste of the food being cooked. They keep the taste pure and gentle.

3. Shelf Life

If kept the right way in a cool, dark place, both oils can last quite long.

Other Healthy Oils as Alternatives

While we’ve compared Canola and Vegetable oils, there are others that are healthy as well. They bring different nutrients and benefits and suit diverse dietary needs and meals.

1. Avocado oil

Take Avocado oil, for example. It does well with searing, browning, or baking foods due to its high heat tolerance. It has more monounsaturated fats than Canola oil but less polyunsaturated fats. However, it may cost you more because avocados are in high demand.

  • Health Benefits and Nutritional Value

Avocado oil carries a good amount of heart-friendly fats and lesser polyunsaturated fats. These nutrient ratios make it a great choice for heart health.

2. Extra Virgin Olive Oil

Extra Virgin Olive Oil is a big deal in the Mediterranean region. It’s a great salad addition thanks to its unique flavour. Its high monounsaturated fat content is good for the heart.

  • Health Benefits and Nutritional Value

Extra Virgin Olive Oil is packed with heart-friendly monounsaturated fat. You can use it safely in low to medium heat cooking.

3. Grapeseed Oil, MCT Oil, Peanut Oil, Sesame Oil

Oils like Grapeseed oil, MCT oil, Peanut oil, and Sesame oil all come with varied pros and cons. They differ in terms of heat tolerance, and health impacts among other things.

  • Brief overview and benefits

These oils bring varied health benefits to the table. For instance, Grapeseed oil is a great all-purpose oil, MCT oil is light on calories but energy-rich. Peanut oil provides many benefits, including a high quantity of resveratrol, a heart-healthy element.

Safe storage of cooking Oils

Correct storage of cooking oils matters. It helps them keep their nutrients and taste.

Tips for proper storage

Store your oils away from oxygen, light, and heat. It’ll make them last longer. Ideally, keep them in a cool and dry place. Avoid placing them near a stove. If the oil bottle is clear, wrap it up in aluminium or similar to block out light. Opened oil bottles infused with herbs and veggies should be kept in the fridge and used within four days.

Factors affecting oil shelf life

The shelf life of oil can be shortened by rancidity. Rancidity speeds up when oil is exposed to light, heat, and oxygen. It often leads to a bad smell or taste due to the breakdown of peroxides.

Signs of rancid oil

Watch out for signs of ageing oils. You’ll notice changes in colour, cloudiness, and a rancid smell. Also, most cooking oils keep their best quality within the first three months after purchase.

Conclusion

While it can seem hard to buy the right cooking oil, knowing what’s what can help. Grasping the ins and outs of oils, especially Canola and Vegetable oils, can be an enlightening experience!

At the supermarket, consider the amounts of saturated and monounsaturated fats, smoke point, and flavour. And don’t forget your dietary needs and cooking requirements. Being open to healthier alternatives like Avocado and Olive oil can work wonders for your health and cooking journey.

Choosing between Canola and Vegetable oil

Picking between Canola and Vegetable oil calls for careful thought. If you’re targeting lower saturates and higher monounsaturated fats, go for Canola. If you want something diverse, Vegetable oil can offer that.

Factors to consider while buying oils

When shopping for oils, always aim for less than four grams of saturated fats per tablespoon. If getting Vegetable oil, avoid those that have partially hydrogenated oils. Look for a blend with canola, safflower, sunflower, and soybean oils. These are lower in saturates. Avoid blends with palm or palm kernel oil.
