Forget Everything You Know About Cooking Oils

 Your entire childhood, you probably saw your good old mom cooking with vegetable oil. Without giving it a second thought, you chomped down every delicious meal made with it, no cooking tastes like mom’s cooking, right? You saw it everyday in the cupboard while reaching for Oreo’s, you saw it on countless grocery lists, etc. What you didn’t know was that your mom, for whom you are the brightest star in the universe, was quite literally poisoning you.

Vegetable oils are processed seed oils like soybean oil, sunflower oil, corn oil, cottonseed oil, safflower oil and canola oil. They are very high in biologically active fats called Omega-6 polyunsaturated fatty acids, which are borderline toxic to the human body.

Let’s look at some other horrific facts about vegetable oils.

Are Cooking Oils Safe or Dangerous?

11 Serious Concerns About Vegetable Oils

Fats in the diet are highly controversial.

Saturated fat was previously blamed for raising cholesterol and causing heart disease, but this has now been disproven .

For some reason, dietary guidelines still recommend that we consume vegetable oils instead of saturated fats like butter.

This includes oils like soybean oil, cottonseed oil, canola oil, safflower oil, sunflower oil and grapeseed oil (and a few others).

Vegetable oils are claimed to lower cholesterol levels, which should help prevent heart disease, the world’s biggest killer.

However… many studies have raised serious concerns about these oils

Despite lowering LDL cholesterol, they can have negative effects on other aspects of health and metabolism.

Here are 11 reasons why you may want to avoid vegetable oils.

  1. Vegetable Oils Are Extremely High in Omega-6 Linoleic Acid

Vegetable oils are the biggest source of Omega-6 fatty acids in the diet… by far.

They are particularly high in the Omega-6 fatty acid linoleic acid. This fatty acid causes a host of problems when consumed in excessive amounts… especially when Omega-3 intake is low (which is usually the case).

Vegetable oils are very high in an Omega-6 fatty acid called linoleic acid, which can contribute to all sorts of problems in large amounts.”

2.Linoleic Acid Builds up in Cell Membranes

Fats are more than just sources of energy.

Studies have shown that the linoleic acid content of human fat cells and cell membranes has increased drastically in the past few decades.

3.Eating Linoleic Acid Increases Oxidative Stress and Contributes to Endothelial Dysfunction

Again, polyunsaturated fats like linoleic acid have two or more double bonds in their chemical structure.

Linoleic acid from vegetable oils increases oxidative stress in the body, contributing to a state called endothelial dysfunction. This is a stepping stone towards heart disease.

4.Vegetable Oils Lower LDL Levels, But They Also Lower HDL

One of the main reasons vegetable oils are (mistakenly) considered healthy, is that consuming them can lower Total and LDL cholesterol levels.

It is true that vegetable oils can lower Total and LDL cholesterol levels. However, they can also lower HDL, the “good” cholesterol.

5.Vegetable Oils Increase Oxidized LDL Lipoproteins

Vegetable oils increase the susceptibility of LDL lipoproteins to oxidation, a crucial step in the development of heart disease.

6.Some Studies Have Linked Them to Increased Risk of Heart Disease and Death

Heart disease is the world’s most common cause of death.

The evidence regarding vegetable oils and heart disease is mixed, but several high quality studies have found them to increase heart disease risk.

7.Vegetable Oils Are a Disaster For Cooking

As mentioned above, one problem with the fatty acids in vegetable oils, is that they tend to react with oxygen.

Vegetable oils are high in polyunsaturated fats, which easily damage during cooking and may even vaporize and form compounds that can contribute to lung cancer when inhaled.

8.Vegetable Oils May Raise The Risk of Cancer

There is some evidence that vegetable oils can raise the risk of cancer.

Several lines of evidence suggest that vegetable oil consumption can raise the risk of cancer, which makes perfect sense given the fact that they make the cells more susceptible to oxidative damage.

9.Vegetable Oil Consumption Has Been Linked With Violent Behavior

One place where polyunsaturated fats gather is in the brain.

Polyunsaturated fats are concentrated in the brain, and many believe that our high vegetable oil consumption is leading to mental health problems, including violent behavior.

10.Vegetable Oils Are Highly Refined and Processed Foods With no Beneficial Nutrients

One thing that most nutrition folks agree on,  is that whole foods are best.

Most vegetable oils are highly processed and refined products, which are completely lacking in essential nutrients.

11.Commonly Sold Vegetable Oils Are Loaded With Trans Fats

Unless you’ve been living under a rock, you’ve probably heard of trans fats before.

They are usually found in highly processed foods. They are so toxic that the governments around the world have set laws in order to remove them from foods.

Take Home Message

There are many healthy fats that humans have been eating for hundreds of years without any problems (since before all the “modern” diseases became common).

This includes extra virgin olive oil (best) and coconut oil. These are exceptionally healthy in the context of a balanced, real food based diet.

Unfortunately, the same can NOT be said about vegetable oils. These are refined and processed fats that have been shown to cause harm in numerous studies.
