Is Oil Vegan? And Why You Should Avoid It If You Want To Lose Weight!

There isn’t one kitchen that you can walk through and not find a bottle of oil close to the stove. And, it is really hard to find any processed food in the grocery store that doesn’t list oil as one of its ingredients.

So true, right? So this begs the question, is oil vegan?

The short answer is that not all oils are. And while the most common oil is vegetable oil, there are lots of other kinds of oils that you might not even be aware of! In this blog post you will learn which oils are vegan and which are not.

You will also learn how healthy are all these oils. And how oil can be detrimental if you are trying to lose weight on a vegan diet. So, keep reading…

How Are Oils Made?

Edible oils are fats extracted from animal or plant sources. Therefore, they are considered to be processed! 

Aside from cooking, baking, and dressing salads, edible oils can also be found in health supplements. Before any extraction process, raw materials undergo cleaning and grinding. 

Afterwards, they pass through magnets to remove trace metals, then hulls or skins are taken off. Once the raw materials are ready for extraction, they undergo heating  and pressing

To further extract more oil, manufacturers use chemical solvents.


Most of the solvents used in oil extraction simply evaporates, while the other remaining solvents are removed by condensation. There are also processes that may alter the chemical compositions of oils to give them the longest shelf life possible.

Lighter but flavorful oils are often cold-pressed and minimally processed. However, cold-pressing is only suitable for a few sources like olive, peanuts, sunflowers, and coconuts.

In early times, and I mean ancient times, people would heat up oily plants until they exude oils. Another method is roasting then grinding and boiling plants until oil rises to the top. These methods are still in use today, commonly by small businesses that offer homemade natural oils.

Other Processes in Commercial Oil Refinement

Aside from eliminating impurities, refining removes color, bitterness, and even odour. This involves the use of high heat and alkaline substances. This process creates a soapy residue, which is removed through a centrifuge.

  1. Degumming – a refinement process that eliminates insoluble substances like phosphorus and fatty acids. This improves the quality and shelf life of cooking oils.
  2. Bleaching – reduces the color through the use of activated carbon or clay that absorbs the pigments.
  3. Winterization – this is only done in oils that will be kept in cold storage, such as those for salad dressing use. To stay liquid even when refrigerated, the waxes are separated by rapid chilling then removed through filtration.
  4. Deodorizing – a distillation method that eliminates volatile tastes and odors by using extreme heat between 440⁰F – 485⁰F.

The amount and method of processing significantly affects not just the quality but also the natural nutritive value of oils. The more refinement it undergoes, the more nutrients are lost. However, some manufacturers replace or add nutrients through fortification.

Common Sources Of Edible Oils

Now that we are clear on how oil is made, let’s find out which oils are vegan and which are not!

1. Vegan Oils

2. Non-vegan oils


Cooking Oils And Smoke Points

When you use cooking oils for frying, do you notice how some oils smoke, burn, and “evaporate” faster than the others? Well that’s what ‘smoke point’ is, put simply. But that’s not all there is to it.

When you heat oil, its properties change, and some, if not all, of its nutrients may evaporate or oxidize with it. Different cooking oils vary in smoke points, but refining processes typically improve smoke points.

The higher the smoke point is, the more refined an oil is. Oils with more saturated fats oxidize slower.

Higher smoke points also allow you to cook longer before you need more oil. However, overheating edible oils past its smoke point may create free radicals.

This is why oils that are less refined or not refined at all, are not ideal for high heat cooking. With lower smoke points, they are more ideal for cooking with minimal heat only, or just for dressing and seasoning use.

So next time you pick oil from the grocery shelves, consider how you’ll use it according to its smoke point.

Ethical Issues In Oil Production

Have you heard about ethical oils? If you are, to some extent, meticulous with where you food comes from, I’m sure you have.

With the continuous rise in demand for edible oils, a lot of companies have turned to drastic measures. The most popular example is that of the palm oil industry which was revealed to be largely responsible for deforestation.

Palm oil is the most in demand oil all over the world. However, to obtain raw materials, many companies destroy rainforests. Consequently, this results to the loss of homes (habitats) for A LOT of forest animals. Can your conscience bear that?

Before this reality came into light, millions of hectares of rainforests and wild animals, especially orangutans were nearly wiped off. Thanks to the growing advocacies towards environmental preservation, more companies are now switching to more ethical sources.

During the height of this controversy, many vegans chose to avoid palm oil products from brands without responsible sourcing. Palm oils are vegan in itself of course. However, its irresponsible production goes against the vegan principle that aims to avoid contributing to animal and environmental harm.

While the palm oil industry is a popular culprit, this ethical issue also happens with other in-demand consumer products. Soybean oil, for example, has also made contributions to rainforest destruction. For this reason alone, many vegans consider oils that are not “deforestation-free” as ethically non-vegan.

Another ethical issue is the exploitation of workers. For example, coconut trade in parts of Southeast Asia use chained monkeys to harvest coconuts. Can you even imagine that? I’ll spare you the disturbing details, don’t worry. Also, in some regions, farmers are overworked and underpaid.

The rise in consumer demand should not be a reason to resort to inhumane measures. Fortunately, there are now more organizations that help to eradicate these practices. It may be quite a long shot, but through the years, it has made a lot of difference already.

This is why for conscious consumers like us vegans, product certifications for responsibility and sustainability are a big deal. Ecolabels like Fairtrade, RSPO, USDA Organic, Food Alliance, and more, all contribute to one or more of these causes.


Oils And Its Fat Contents

Edible oils are fats whether they come from plant or animal sources. While it’s worth noting that not all fats are bad (and we need the good ones!), oils do have both. Take a look at these common fats found in oils.

1. Saturated

(no double bonds) – commonly found in animal food sources. They are solid at room temperature, and can increase bad cholesterol levels.

There are contradicting studies about its effects on health until today. However, the American Heart Association recommends that they only make up 5-6% of your total daily calories.

2. Unsaturated Fats

the good fats! Well, mostly. It is liquid at room temperature, and can improve cholesterol levels.

      a. Monounsaturated (1 double bond)

      b. Polyunsaturated fats (2 or more double bonds)  

  • Omega 3
  • Omega 6

3. Trans fat

the worst kind of fat that often results from hydrogenation during food processing. It is also known as hydrogenated oil.


The Vegan Oil FAQs

Do you still have questions? I’m far from done yet! Here are the most common questions you might still be asking.

1. Is coconut oil vegan?

Coconut or copra oil is vegan. It is one of the most popular oils with immune-boosting properties. However, it is higher in saturated fats than other oils.

Here are some great vegan coconut oil brands (for cooking, baking, and hair/skin care!):

  • Viva Naturals organic, cold-pressed, unrefined, made from fresh, hand-picked coconuts
  • Nutiva – organic, cold-pressed, unrefined, non-GMO, non-hydrogenated, Fairtrade-certified
  • Vita Coco – ethical, cruelty-free, organic, BPA-free packaging, unrefined

2. Is palm oil vegan?

Strictly speaking, only “deforestation-free” or “ethical” palm oils are vegan. However, palm oil, in itself, which is from the fruits of palm trees, is vegan. Here are eco-friendly, vegan palm oil brands you can try:

3. Is sustainable palm oil vegan?

Yes. While they are less common, responsibly-sourced palm oils are vegan. They are the ones made with commitment to environmental consideration.

4. Is olive oil vegan?

Yes! They are made from olive fruits. Light olive oils are more ideal for cooking than the popular extra virgin variety. Most olive oils today have some percentage of EVOO in it. Also, you’ll find that there are so much more EVOOs than regular olive oils.

5. Is extra virgin olive oil vegan?

Yes. The label “extra virgin” only refers to the lack of refining process. Extra virgin olive oils (EVOO) are ideally cold-pressed and does not use any chemicals. However, with a low smoke point, EVOOs are not ideal for cooking and are best for salad dressing use instead.

Be careful when buying olive oils though. As it turns out, majority of olive oils sold in the US (and other countries) are actually fake. Fake olive oils are either olive oils diluted with cheaper oils, or a mixture of cheaper oils flavored with olive. Choose brands with certifications of authenticity.

6. Is vegetable oil vegan?

In itself, yes. However, depending on the manufacturing process, non-vegan ingredients may be present. Ethical sourcing and production must also be put into consideration. Cooking oils with “vegetable oil” labels is often a combination of different vegetable oils.

7. Is sunflower oil vegan?

Yes. They are made from sunflower seeds. It’s a versatile oil that can be used for cooking and skin care. Try these eco-friendly, vegan sunflower oil brands:

8. Is canola oil vegan?

Yes it is. Canola oil is from the seeds of a modified rapeseed plant that was first bred in Canada. Hence its name that came from “Canadian oil”. In contrast with rapeseed oil, canola oils have less than 30 micromoles of glucosinates and less than 2% erucic acid.

Vegan canola oil brands:

9. Is sesame oil vegan?

Yes, they are from sesame seeds. It is more stable and is known to be high in Vitamin K. Its nutty flavor makes it more ideal for seasoning than cooking.

Some vegan sesame oil brands you can check out:

10. Is rapeseed oil vegan?

Extracted from the seeds of the rape plant, yes it is vegan. Rapeseed is high in erucic acid and glucosinates, but new varieties have been bred to reduce this significantly. Here are some vegan rapeseed oil brands:

11. Is fish oil vegan?

No. Obviously, they are derived from fish, but are more commonly used in nutritional supplements and not for cooking.

12. Is soybean oil vegan?

Yes. However, if you’re a strict vegan, you might want to look at ethical brands. The soybean industry is known to contribute to deforestation as well, so choose eco-friendly vegan soybean oil brands like this:

13. Is corn oil vegan?

Yes, it is made from the germ of corns. Also known as maize oil, it has a high smoke point which makes it ideal for frying. Do note though that corns are often a victim of genetic modification, so choose non-GMO vegan corn oil brands only. Here’s one:

14. Is cottonseed oil vegan?

Yes. Made from the seeds of the cotton plant, it’s also a versatile oil which is high in unsaturated fats. However, its use for cooking is not as popular as it is in Africa. This means finding a good brand available in the US will be tough.

15. Is peanut oil vegan?

Yes it is. Peanut oil also has antioxidant properties. It also comes by the name groundnut oil (peanut is a type of groundnut). Check out these vegan peanut oil brands:

16. Is Olba’s oil vegan?

Yes. It is a brand of essential oil made by combining eucalyptus, peppermint, wintergreen, juniper berry, cajeput, and clove. It is not an edible oil, but is vegan-friendly.


Which Oils Are Not Vegan?

This question may sound silly but if you think about it, it’s actually a valid question. For one, with the way food processing goes these days, including the cryptic names of food additives, it can be hard to tell what really goes in that food package.

This is the case with some edible oils, because a lot has to be done to make it what it is. In the strictest form of veganism, these are the things that can make any oil non-vegan:

1. Unethical sourcing

The good thing is, sustainable brands are now easier to spot because it’s something they can boast on their labels. The RSPO (Roundtable for Sustainable Palm Oil) certification for example, is your green light for ethical palm oils.

Otherwise, you’d be left in doubt if that package of oil killed orangutans, elephants, rhinos and whatnot on its way to you.

2. Non-vegan ingredients

The more refined a cooking oil is, the more you can bet there are other stuff in it. Commonly, cooking oils that don’t include the name of its primary source (or even its ingredients!) are made up of different oils, and can be a mixture of both vegetable and animal oils. Opt for oils with 100% traceability as much as possible.

3. Contamination during manufacture

Or more specifically, contact with non-vegan ingredients during production, whether intentional or not. The most common giveaway you’ll see is when packages say something along the lines of “made in a facility that also produces dairy, meat (and other non-vegan stuff)”.

This is quite  uncommon with edible oils though, but it doesn’t mean it doesn’t happen.

Do Edible Oils Have Health Benefits?

Vegetables, nuts, and seeds can easily make anyone think that anything that comes from it is healthy. This is probably why a lot of people think using oil is healthy.

Depending on the source material and processing done, oils may have potential health benefits.

For example, cold-pressing preserves some of the natural nutrients in oil sources. Conventional refining, on the other hand, strips off these naturally-occurring nutrients.

Here are some of the popular oils and their natural nutrients:

Canola – contains Omega 3 and 6, plant sterols, and vitamin E

Coconut – high in MCTs (medium-chain triglycerides) and contains lauric acid, which has antibacterial, antifungal, and antiviral properties

Corn – it has linoleic acid, vitamin E, and plant sterols

Olive – rich in antioxidants, contains oleic acid, and some E and K vitamins

Palm – contains some vitamin E, carotenoids, palmitic acid, oleic acid, linoleic acid, and stearic acid

Peanut – contains vitamin E and phytosterols

Sesame – has Omega 3 and 6, and some vitamins E and K

Soybean – has linoleic acid, plant sterols, vitamins E and K

Keep in mind, however, that some of these nutrients are often insignificant in amount. They may also change during processing and heating.


The Health Effects Of Oil Consumption

While edible oils are very much widely used, it is recommended to keep consumption to a minimum.

Sure, it makes a lot of food taste so much better, but do you know what oils do to your body when you enjoy it regularly? Although usually made from ‘vegetables’, they are not as healthy as it sounds.

Here are some of the negative effects of oils in general:

  • Can slow down blood flow
  • May increase risk of obesity
  • Exposure to toxic chemicals during heating
  • Excessive Omega 6 contributes to chronic inflammation
  • Too much polyunsaturated fats can make your body more sensitive to oxidation
  • High trans fats make you prone to chronic illnesses

Oils may have additional health benefits, which I’m sure are being pointed out to you in the packaging labels.

However, these benefits that brands claim are often insignificant,  and you’d have to consume so much oil to even really see any benefit. By the time you do, you’ll have more fats and calories than whatever benefits you got are worth.

In short, it’s NOT worth it. So just use oils sparingly.

Another thing:

If you regularly consume packaged food products or eat in restaurants, you should include this when counting your oil consumption.

Oil is a regular ingredient in fast food and processed foods. What’s worse is packaged food products often contain hydrogenated oils too, the bad one! Yikes!

Oil Substitutes: What’s Better Than Oil?

It is true that we need good fats for better health, but obtaining these good fats from whole foods is the way to go.

Think avocadoes, nuts, and seeds. Edible oils are processed foods that must only be consumed in moderation, or better yet, not at all. If you think you’ve been consuming too much oils, you can replace them with these:

For baking, you can substitute half or all of the oil with any of the following (consider the taste combination):

  • Mashed bananas
  • Fruit purée
  • Applesauce
  • Cornstarch (with water)

If you must cook in high heat, choose oils with higher smoke points such as:

  • Avocado oil
  • Coconut
  • Corn oil

Smoke points are often written in the package labels. If not, look for it in the product’s website.

Only use your cooking oils up to their given smoke point. This will prevent too much oxidation that can expose you to free radicals and other toxic chemicals.

What To Look For If You Must Choose Oils

Now I know most of us will still have to do some cooking during most days. If you find it difficult to completely avoid oil, you can still use a bit of it every now and then. Here are the things you should look for when buying oil:

  • Minimally processed, or if possible, not processed at all
  • Cold-pressed or expeller-pressed
  • No trans fats
  • Ethically and responsibly sourced
  • Non-GMO
  • Organic
  • Eco-friendly (look for ecolabels)
  • Not packed in plastic (choose bottles or other eco-friendly packages)

Oil and Weight-Loss

I will cut right to the chase. Ready for it?

Stop using oil to cook your food!

Don’t drizzle oil on your salad.

And if you want to take it to the next level for maximum results, don’t buy food that contains oil (read the ingredient list on the packaging label for this).

In general, 1 tablespoon of oil is a whopping 120 calories.

Think about it, every time you add a tablespoon of oil to that pan when you are cooking dinner, know that you will already have added 120 calories to your meal without actually eating anything!

Do you know what is also 120 calories (or less):

  1. 1 pound of spinach
  2. 12 stalks of celery
  3. 28 baby carrots

Wow! I don’t even think I could finish 12 stalks of celery, I would be full half-way through. But a tablespoon of oil? I would need to drink manyyyyyy tablespoons to ever get full.

Understand that you don’t need oil to cook. You can bake your food. You can steam your food. You can put your food in the microwave or toaster. There are non-sticking pans you can buy (although the ones are expensive). I even own an air-fryer!

There is no excuse to use oil.

When I made this one little switch, I lost 5 pounds in a few months. It required no effort from me. Super simple!

Give it a shot! What do you have to lose? Only 5 pounds!

Most edible oils are vegan, but still, must only be used minimally or not at all.

 Edible oils are still fats no matter what vegetable, nut, or seed they come from. Although most oils contain nutrients, their fat content is significantly high. Also, most oils are unstable in high heat and may release toxic chemicals during oxidation.

With no clear health benefits and heavy processing, oils definitely lean more towards the unhealthy side. Not too mention, they stay around your waist too! So if you are trying to lose weight on a vegan diet, oils are a no-no.
