Frequently Asked Questions

Vegetable oil is a mix of different plant seeds, nuts, and less commonly from fruit seeds. It's a pure liquid fat that has been harshly treated with aggressive levels of heat, solvents, and chemicals.

The main ingredients used are rapeseed and soybean oils because of their cheap costs, although there are many different variations this is the typical base.

Vegetable oil is made from many different kinds of plant or fruit seeds and nuts. Most commonly found are canola, cottonseed, soybean, sunflower, and olive oil mixes. The seeds are separated by source and taken to extraction chambers, they're heated, rinsed with solvents, and then pressed to soften their oily barriers.

After softening the seed they're then sent to a was to have the oils completely separate from the cakey residue. At this point, the vegetable oil is heavily mixed with solvents and goes through more treatments to remove the chemicals used in the earlier processes.

The product is now heavily foul smelling and rancid, the next treatment bleaches and deodorizes the oils to mask the smell and keep the color consistent. After going through more heating treatments it's then bottled for distribution.

No, vegetable oil has a few positive health effects (that you can find everywhere else) and is outweighed by the plethora of negatives. It has always been branded as heart healthy because of its good amount of omega-3s, but fail to market the fact that the oil is completely rancid, full of oxidized fats, harmful free radicals, saturated fat, and loads of trans fats.

Through all of the harsh treatments the final product goes through, there's no way vegetable should be considered "heart healthy". There have been many studies pointing to the causation of many heart and organ related diseases, complications, failures, cancers, and infections.

Vegetable oil is available almost anywhere, many major supermarkets such as Walmart, Metro, and in online market places such as Amazon.

Being cheap for the amount of volume you get makes it a really common option for man households. Sitting between 0.14$ to 0.23$ per 100/ml.

Break Down and Background

Vegetable oil is a widely used household frying oil that has many variations and different ingredients. It's a tricky product to analyze since it has so many variables.

It contains both omega-6 and omega-3 fatty acids. They're essential omega fatty acids, that can only come from your diet since your body can't produce them.

The typical North American diet has a poor ratio of omega-3 to omega-6 fats that can cause a series of chronic internal inflammation, cancer, diabetes, and cardiovascular disease.

We'll be covering vegetable oil variations from the most basic ingredients to the more complex ingredients used in making vegetable oils, lard, or shortening. Which can include in part or in whole:

Unlike the popular olive oil and coconut oil extraction method of cold pressing the ingredients to create the final product, plant-based oils can be done in many harmful, toxic, and unnatural methods.

Olive oil or canola oil are the primary ingredients and base of almost all vegetable oil-based cooking products and was granted approval to be used in U.S food markets in 1985.

This spiked the rates of heart disease and cardiovascular complications throughout the country ever since.

Vegetable oil is also an ingredient used in many desserts, salad dressings, vegetarian and vegan friendly foods, ready-to-go meals, and fried food recipes.

Vegetable oils have a global consumption rate of almost 200 million metric tons per year, sitting at around a 26$ billion to 27$ billion dollar market.

It's best not to get mixed up between the actual vegetable oil product and the category of produce oils; such as soybean oil, corn oil, peanut oil, as well as other edible and essential oils.

Most mainstream health and medical professionals, dietitians, and the American Heart Association (AHA) consider vegetable oil to have great health benefits, but in reality it can cause heart disease and a variety of other health problems.

Here's how vegetable oil is made:

  1. The canola oil base is made with a GMO version of rapeseed that's also heavily treated with herbicides and pesticides.

  2. The rapeseed plant is then deseeded, crushed to soften the outer seed coat layer.

  3. The flakes are then transitioned to a steam heated drum or stack cooker to rupture the vegetable oil membranes. This reduces its viscosity, helping the droplets to clump up and bind together denaturing their hydrolytic enzymes (breaking down its fat molecules).

    The vegetable oil is quickly heated from 80 to 90°C (176 to 194°F) to break down the myrosinase enzyme in canola, myrosinase hydrolyzes the glucosinolates (the defense mechanism of cruciferous plants when damaged) that destabilizes the oil.

    Breaking down this enzyme keeps the product stable, and some manufacturers have reported reaching heats of up to 120°C (250°F) for 15 to 20 minutes.

  4. The mix is then pressed together to form a mix of thick cell membranes and residues called a press cake. A petroleum solvent (hexane) is then used to penetrate the cake and extract the trapped oils. At this stage, the mix is 99% petroleum and less than 1% canola oil.

  5. It's then heated once again from 95 to 115°C for 1 to 1.5 hours to remove the solvent and moisture.

  6. Finally, the fats are then refined with a color enhancing chemical, it's then deodorized to improve the color and mask the smell from the chemicals and rancid oils.

That's just the base, not exactly a healthy choice but it's still regarded by the health community as a heart healthy product. A step above that is margarine, which hydrogenates the canola as well as other legume and nut oils.

Then you'll have a solid piece of margarine that's high in omega-6, saturated and trans fats.

Along with the continued myths behind saturated fats and cholesterol levels, it's promoted as being heart healthy because of the good source of omega-3 and omega-6 fatty acids, saturated fats, and polyunsaturated fats.

The final product is given a deceiving name when in actuality, whole vegetables are not used nor contain any oil what so ever. This is a marketing trick that gives a harmless name to a harmful product.

The list of the vegetable oil benefits and side effects vary depending on how high in omega-6 fatty acids they are, what genetically modified (GMO) plants they’re extracted from, and how they’re processed.

These are not our preferred vegetable oils of choice when it comes to eating and feeling your best. Especially since this is a mix of the most oxidized oils and harmful fats mixed into one product, vegetable oil.

An extra virgin olive oil base can be the exception, but because of the processing needed to produce one uniform oil, they destroy most of the beneficial properties of the olive based vegetable oil.

What does using these ingredients say about it’s quality and safety? It’s classified it as a waste product. Produced from the waste and residue of other manufactured products.

Originally, that other product is hand soap, designed in the late 1800s to 1900s. The waste that comes from it’s production was an early form of cottonseed oil

The byproducts and waste ingredients was used back then and is even now used with no major innovations since its conception.

Vegetable Oil Health Benefits

The advantages of using it are few and far between. With all of the toxic process and refining systems done to the natural oils before creating a finished product labeled as a vegetable oil, you’ll find that the list of its beneficial results are few and very short lived.

There are a few redeeming qualities, one of which is its high smoke point. This is the reason why brands advertise it as a frying oil since it's more efficient at deep frying foods compared to other vegetable oils on the market.

Vegetable oil also contains a small amount of saturated fat, monounsaturated fats, high levels of omega-6 fats, and some levels of omega-3 fatty acids most of which have gone bad; all while having 0 grams of trans fats.

1. Can Increase Your Metabolism

A study conducted in Sao Paulo State University states that the olives that are used in typical vegetable oils have been shown to benefit fat loss by increasing your basal metabolic rate (BMR).

This is because these good fats have important alpha-linolenic acids, phenolic compounds, anti-blood clotting, and anti-inflammatory, as well as the loads of antioxidants; all of which leads to increasing your overall basal metabolic rate.

2. May Improve Your Heart Health

Unsaturated fats are found in abundance. According to the study conducted in the State University of New York, they found that you can reduce bad LDL cholesterol, heart complications, and raised healthier blood sugar levels in people who used legume or nut based oils in their diets on a regular basis.

Vegetable Oil Side Effects and Detriments

1. Triggers Many Chronic Diseases

Chronic inflammation is a major factor of the typical American diet, especially because of its continued growth in popularity.

Many studies show that a diet with an elevated level of omega-6 fatty acids increased your risk of heart disease, obesity, arthritis, inflammatory bowel, and cardiovascular disease.

Issues stemming from vegetable oil consumption are comparable to vegetable shortening.

Vegetable oil is an unhealthy substitute for butter, and if consumed too much and too often it can cause very harmful problems down the line due to all of the omega-6 fats.

A few less common diseases caused by vegetable oils include:

  • Age-related macular degeneration

  • Higher rates of miscarriages

  • DNA oxidation

  • Retinal pigment epithelial degeneration

  • Premature rupture of cell membranes

Now we get into the core of the negative effects when consuming vegetable oil. First is the quality and source.

2. The Healthy Fats Become Toxic and Rancid

The quality of the mixed oils which make up the vegetable oil are all full of toxins. From the multiple bleaching processes to the extreme heats exerted on the product, the finished product becomes mostly oxidized and rancid from all of the processing.

obesity and diabetes

It gets exposed to high pressures, chemical agents, light, and air. All of which are what causes the vegetable oils to go bad and develop free radicals.

These vegetable oils have a long history with promoting heart disease and cancerous results in clinical testings.

The chemicals used to produce vegetable oil have been shown to produce potential cancer-causing compounds in the body, and have also been linked to liver and kidney damage, heart disease, immune problems, infertility, and high levels of cholesterol.

The canola oil treatment process, which is also the base of all vegetable cooking sprays as well, have had their beneficial fat compositions destroyed by all of the harsh chemicals, high levels of heat, and oxidation.

The biggest cause for concern with the oxidated oils is that it rids your body of any antioxidants, these are used to neutralize oxidation that you get from eating and natural oxidative stress happening to your body over time.

Our body produces these during our regular metabolic processes. Some metabolic processes include:

  • Repair and function of the brain and internal organs

  • Repair, maintenance, growth, and functioning of skeletal muscles

  • Joint and bone mass preservation

On top of that, in a reserved animal study, the rats were fed a diet high in polyunsaturated and omega-6 fatty acids coming from vegetable oil.

In excess of these harmful fats, it inhibited their ability to learn especially under conditions of stress, created toxic waste in the liver, compromised the integrity of the immune system, and depressed the mental and physical growth of infants.

cotton seed oil

The increased levels of uric acid in the bloodstream; causes abnormal fatty acid profiles in the fat tissues has been linked to mental decline and accelerate aging. Excess consumption of PUFAs is associated with an increased rate of cancer, heart-related diseases, and weight gain.

3. Polyunsaturated Fats Oxidize Easily

What makes omega-6 fats oxidize easily is the number of double bond chains in its chemical makeup, the more double bonds the more sensitive the oil.

They have 2 or more carbon to carbon double bonds, these bonds deteriorate very easily when exposed to air, heat, and light. Saturated fats have 0 double bonds while all monounsaturated fats have at least 1.

The dangerous part about having a diet high in PUFAs is that they get stored in your cells for energy. The more your cells accumulate the more prone you’ll be to oxidative stressors.

4. High in Trans Fats

Vegetable oil is high in trans fats, regardless of the nutrition label marker. After going through the different refining phases the product becomes spoiled and is treated to remove any traces (deodorizing, bleaching, mixing, etc).

This makes it so over time, the vegetable oil begins to form harmful agents within itself and this causes the development of trans fats. A research paper has revealed that the average amount found sits between 0.55% and 4.3% of the total volume.

5. Increased Risk of Cardiovascular and Heart Disease

It’s widely suggested that you consume legume or plant-based vegetable oils help reduce your risk of heart disease because of its low levels of saturated fatty acids.

The issue evolves when your diet is full of omega-6s since it can cause inflammation in your heart cavity and all of your other organs.

The research done on the effects of these fats with lowering your bad cholesterol levels is not conclusive, and with all of the adverse detriments stacked against it, it’s best to avoid it altogether. Omega-3s are much more important and effective at controlling your risk of heart disease.

Rating and Recommendation

Extremely Not Recommended

In every case scenario, it should be avoided at all costs.

The positive health effects that are left in finished vegetable oil products is not worth taking a risk on the plethora of negative side effects caused by consuming a rancid and hydrogenated variation.

Regardless of any benefits, with many studies concluding that consuming vegetable oil exposes you to an increased risk of cancer, kidney, liver, heart disease and other issues. It’s not a healthy choice for home cooking or otherwise.

Because it’s so high in trans fat, saturated fat, and omega-6 fats it will lead into so much oxidative stress and DNA damage over time that you should strictly avoid it.

You should think twice before using any to cook your food with and instead, you can use coconut oil for deep frying and cooking in higher temperatures as well as olive oil when looking to pan fry over a stove.
