The Ugly truth about vegetable oils you should know!

The Ugly truth about vegetable oils you should know!

Is vegetable oils the healthiest cooking oil?

The ugly truth is NO! I get a lot of questions about what fats and oils I use for cooking. It makes sense; after all, there is much confusion about fat in general. So with the increasing hype over “heart healthy” vegetable oils and their sky-rocketed consumption level, it is no wonder people have questions about these highly over-recommended products. So let’s talk about vegetable oil: What are they? Why do I avoid them? Lets find the healthiest cooking oil?

Ready? Let’s do this.

Vegetable Oils ! What are they?

Vegetable oils are oils that have been extracted from various seeds. The most common include rapeseed (canola oil), soybean, corn, sunflower, safflower, peanut, etc. Unlike coconut oil or olive oil that can be extracted by pressing, these new-fangled oils have to be extracted in very unnatural ways.
A non-traditional food with a questionable short history

Unlike traditional fats (butter, tallow, lard, olive oil, etc.) our industrial vegetable oils are a very new addition to the “food” world. In fact, they were practically non-existent until the early 1900s. However, with the invention of certain chemical processes and a need for “cheap” fat substitutions, the world of fat has not been the same since.

Consider that at the turn of the 20th century that amount of vegetable oils consumed was practically zero. Today the average consumption is 70 lbs a year. Per person. (And since I know plenty of people who do not touch the stuff, that means lots of people are consuming even more!)

The truth about vegetable oils: And why you should avoid them!

Of course, that number jumped dramatically once the campaign against saturated fats and cholesterol took its public rampage. (Hint: Cholesterol and Saturated Fat are essential to good health.)

Even today, despite the fact that heart disease and cancer continue to rise at an alarming rate while butter consumption is down (and vegetable oil consumption is at an all-time high), people are still believing the hype and buying this very non-traditional, non-healthy food-like product.

Vegetable oil: an unnatural process from the start.

Before we talk about the process by which vegetable oils are made, let’s first look at one of my favorite traditional fats: Butter.

Butter is a simple process that comes when cream separates from milk. This is a natural process that only takes a little patience. Once the cream and milk have separated, all you need to do is skim off the cream and shake it until it becomes butter. (And it really is as easy as it sounds, I’ve made butter lots of times. Takes about 5 minutes.)

Now let’s compare that to the production of canola oil. Here’s an overly simplified version of the process:

  • Step 1: Find some “canola seeds.” Oh wait, they do not exist. Canola oil is made from a hybrid version of the rapeseed… most likely genetically modified and heavily treated with pesticides.
  • Step 2: Heat the rapeseeds at unnaturally high temperatures so that they oxidize and are rancid before you ever buy them.
  • Step 3: Process with a petroleum solvent to extract the oils.
  • Step 4: Heat some more and add some acid to remove any nasty wax solids that formed during the first processing.
  • Step 5: Treat the oil with more chemicals to improve the color.
  • Step 6: Deodorize the oil to mask the horrific smell from the chemical processing.

Of course, if you want to take your vegetable oil one step further, just hydrogenated it until it becomes a solid. Now you have margarine and all its trans-fatty wonder.

Whats Wrong with Vegetable oil?

Hopefully, at this point, you can see how NOT real these oils are. And in my book, “not real” is reason enough to avoid them. So how can they continue to be marketed as “heart healthy”?

Along with the continued myth about saturated fats and cholesterol, these oils are promoted as healthy because they contain monounsaturated fats and Omega 3 fatty acids. So that is what advertisers focus on to draw you into the fake health claims. However, it does not paint the whole picture.

Without going into extreme detail (although I’ll link up to more reading if you want all the gruesome details), here are the many problems with vegetable oils:
The polyunsaturated fat issue

Vegetable oils contain very high levels of polyunsaturated fats (PUFAs). However, did you know that the fat content of the human body is about 97% saturated and monounsaturated fat? Our body needs fat for rebuilding cells and hormone production. Also, it can only use what we give it.

Polyunsaturated fats are highly unstable. They oxidize easily. These oxidized fats cause inflammation and mutation in cells. That oxidation is linked to all sorts of issues from cancer, heart disease, endometriosis, PCOS, etc. PUFAs are bad news.

Omega 6 issue

There’s much hype about Omega-3’s and how healthy they are. However, what often gets neglected is the fact that it is more about the ratio of Omega-3 and Omega-6 fats that are critical to good health.

Vegetable oils contain a very high concentration of Omega 6 fatty acids. These fatty acids oxidize easily. Omega-3 fatty acids have been shown to reduce inflammation and protect against cancer. Unbalanced levels of Omega-3 and Omega-6 fats have been linked to many types of cancers and a host of other problems. Moreover, as you’ve probably guessed, most Americans are high in Omega-6 fatty acids and low in Omega-3’s. However, people keeping buying into labels on vegetable oils that say “a good source of Omega-3s” without realizing that they are just making the imbalance even worse.
All the other bad “stuff.”

Beyond the unnatural levels of polyunsaturated fats and Omega-6 fatty acids, there are all the additives, pesticides, and chemicals involved in processing. Many vegetable oils contain BHA and BHT (Butylated Hydroxyanisole and Butylated Hydroxytoluene). These artificial antioxidants keep the food from spoiling too quickly, but they have also been shown to produce potential cancer compounds in the body. Moreover, they have been linked to things like immune system issues, infertility, behavioral problems, and liver and kidney damage.

Oh yeah, and many vegetable oil come from genetically modified sources. Not sure why that is bad? Check this out.

In a nutshell, these oils are extremely unhealthy. They’ve been linked to reproductive problems, low birth rate, hormonal issues, obesity, mental decline, liver problems, and the big problems of our day: cancer and heart disease.
So what is safe to use?

In a world that seems overrun with these highly unnatural and toxic fats, it can seem overwhelming when looking for better solutions. And if you try to keep up on the latest “scientific” findings you may be even more confused. Luckily, you do not have to be a nutritionist to know the best fats to use. Look to your ancestors. Look to what food was before the chemical and industrial age came in and made a mega-mart of imposters.

To help you, here are some guidelines when it comes to fats and oil.

Healthy Fats for Cooking !

What is the healthiest cooking oil?

When it comes to any food, keep in mind that where it comes from and how you store it can matter greatly. Traditional oils should be cold-pressed. Organic when possible (especially when dealing with animal fats as the fat is where toxins/pesticides are stored). Do the best you can, and don’t get overwhelmed by all the choices.

  • Coconut Oil (Use expeller-pressed to avoid a coconut flavor)
  • Tallow
  • Lard
  • Butter
  • Palm Oil (Although, please find from a sustainable source as so much palm oil today is being harvested in horrific ways. When in doubt just stick with coconut oil.)
  • Extra-Virgin Olive Oil (Great for non-heat dishes like salad dressings, humus, mayo, etc. Can be used in cooking at lower temperatures or when combined with another saturated fat like butter or coconut oil.)
  • Avocado Oil (Great for non-heat dishes)
  • Other fats (not necessarily for cooking, but essential to good health) include meats, eggs, dairy, and fish (nuts are also good in moderation as they have a high level of polyunsaturated fats).

Oils to be used sparingly

The following oils are okay in moderations. Most contain high levels of Omega-6 fatty acids, so they should not be consumed freely. However, they are considered natural fats and do have health benefits. They are not great for high heat cooking, but acceptable in dressings, mayos, and other non-heat foods.

  • Walnut Oil
  • Flaxseed Oil
  • Macadamia Nut Oil

Oils to avoid completely

Here’s the big list I avoid as much as possible:

  • Canola Oil
  • Corn Oil
  • Soybean Oil
  • “Vegetable” oil
  • Peanut Oil
  • Sunflower Oil
  • Safflower Oil
  • Cottonseed Oil
  • Grapeseed Oil
  • Margarine
  • Shortening
  • Any fake butter substitutes

Simply skipping these oils in the grocery story is not too hard. However, keep in mind that most processed foods contain these oils, too. Salad dressing, condiments, crackers, chips… check your ingredients. Don’t buy them. In fact, just skip processed foods and you’ll save yourself much trouble.

It is hard to avoid rancid vegetable oils completely if you are eating out, and I try not to stress about the occasional night at a restaurant. By keeping these bad boys out of my house, I feel okay consuming these oils when out with family or friends. However, if I find a restaurant that uses quality fats, you better believe they’ll be getting my business!
