What Are Vegetable Oils?

Oil is a processed food that comes from a whole food. It takes 1375 olives to make a liter(34 f oz) of oil!

When they manufacture oils, they separate the oil from the vegetables, nuts or seeds. You can do it in two ways. Either by heating up the produce and then squeeze out the oil.

Or only use a mechanical process. This process is a lot slower than heating up the crop and yield less oil.

So why are vegetable oils bad for you? Let's find out.

Why Vegetable Oils Are Bad For You

Vegetable oils are pure fat and lack nutrients. It's the most calorie dense substance you can eat.

Oils clog arteries which lead to heart disease. Vegetable oils also raise the risk of cancer.

Have you ever done your dishes and let the oil go down your sink? If you do it often, you will clog your pipes.

Extra Virgin Olive Oil

When fat goes down the drain, it hardens and obstructs sewer pipes. Fats lead to a sanitary sewer overflow where raw sewage backs up into your home and streets.

Not only does this nasty mess cause health issues, but it also can run into a nearby stream or river.

Restaurants are responsible for proper disposal of their fats, oils, and grease (FOG). They must maintain a grease trap to stop oils from entering the main sewer line.

If oils cause all this problem to the sewers imagine what they will do to your body?

Millions of dollars are spent each year cleaning out sewer pipes clogged by FOG.

Refined oils are one of the worst oils. These oils cause serious health problems. So what are refined oils?

The Dangers Of Refined Oils

Refined vegetable oil starts from the seeds of various plant sources.

There are many different kinds of commercially refined vegetable based oils, these include:

  • Canola oil
  • Corn Oil
  • Safflower oil
  • Soybean oil
  • Sunflower oil
  • Peanut oil

Manufacturers create refined oils by using intensive mechanical and chemical processes. Through this method, they extract the oil from the seeds.

This process removes the natural nutrients from the seeds. Oxidation occurs when they separate the oil from the seeds. Cancer-causing free radicals are a result of oxidation.

To create refined vegetable oils it has to take several steps, these include:

The Refined Oil Process

1. Gathering seeds such as soybean, rapeseed, cotton, sunflower

2. Cleaning the seeds from dirt and dust then crush them

3. Heating the crushed seeds in a steam bath

4. Use high heat and friction to press the oil from the seed pulp

5. The seed pulp and oil are then put through a hexane solvent bath and steamed again to squeeze out more oil.

6. The oil mixture goes through a centrifuge. Producers then add phosphate to separate the oil and seed residues.

7. After solvent extraction, the oil gets separated, and the water evaporates.

8. The vegetable oil is then going through further refining techniques. These include degumming, neutralization, and bleaching

9. Deodorization is the final step in the refining of vegetable oils. Steam at high temperature removes odors and tastes in the end product.

If you thought that was bad, then you will not like what I'm going to tell you next.

Hydrogenated Oils And Its Devastating Effect On Our Health

The process of refining vegetable oil damages the fats and makes the oils go rancid.

The makers didn’t stop there. They wanted to create a cheap alternative to butter by using vegetable oils. The problem is that oils are liquid at room temperature.

So to make the oils firm, they had to alter the molecule structure of the oils.

This process is called hydrogenation. During hydrogenation, the producers add hydrogen gas to the oil under pressurized conditions.

Hydrogen particles bind with the fat and increase the melting point.

Margarine is the name of the end product. Did you know that margarine is one molecule from plastic?

If you let, margarine stay in the pantry bacterias won’t touch it.

You can try it for yourself. Take your margarine and let it stand in the cupboard for months. You will notice that it won't decompose by bacteria.


Margarine is just one molecule from plastic

There is no wonder that margarine is bad for your health.

If you love French fries then you need to pay attention next.

French Fries Are Cancer Sticks

French fries raise the risk for cancer. One study examined French fries, fried chicken, fried fish, and doughnuts. They found out that these foods increased the odds of getting prostate cancer by 33%.

Some studies linked acrylamide in French fries to endometrial-, ovarian-, and lung cancer. They also saw connections to kidney-  and esophageal cancer.

Many of us have heard that you need omega 3 by using fish oils. But did you know that fish oil can increase the risk of prostate cancer?

Fish Oils Can Lead To Prostate Cancer

Scientific research shows that fish oil does not lead to better health. Fish oils don't appear to decrease death, heart attack, or stroke, but also elevate the cancer risk.

Men with high levels of long-chain omega-3 fat are at greater risk for prostate cancer. Some industrial pollutants like PCBs increase the prostate cancer risk. The general population gets PCBs from fish, meat, and dairy products. 

Fish oil supplements

Fish oil can increase the risk of prostate cancer

PCB is highest in freshwater fish. Because vegans don't eat animal products, they have less PCB than meat eaters.

Fish oil is not essential. Fish get their omega 3 from plants. Being deficient in Omega 3 is difficult. 1-2 tablespoons of ground flaxseeds are enough to meet your daily need of omega 3. Other ways to get enough Omega 3 is to eat green leafy vegetables at several meals.

Those on a plant-based diet become quite efficient in creating their own omega 3.

Trans fat is another death trap you need to avoid.

Trans Fat Increases The Risk Of Sudden Death

Animal fat and hydrated oils are the biggest sources of trans fats. Trans fats increase one’s risks of heart disease, sudden death, and diabetes.

Trans Fat

  • Trans fats are inside animal fat, dairy products, and hydrogenated oil
  • This fat is solid at room temperature and makes crispier crackers and flakier pie crusts
  • Common in: Animal meat, processed food, chips, crackers,cookies, margarine, salad dressings, margarine and hydrogenated oils

The National Academies of Science concluded there is no safe intake of trans fats. According to the official USDA Nutrient Database, animal products contain up to 1 to 5% trans fats. 

Some of these food include:

  • Cheese
  • Yoghurt
  • Chicken fat
  • Bologna
  • Milk
  • Burgers
  • Turkey meat
  • Hot Dogs

They also found small amounts of trans fats in non-hydrogenated vegetable oils. There is a dispute whether the trans fats in animal products are as bad as the fats in hydrogenated oils.

Recent studies support the claim that all trans fats increase heart disease. That is true whether it comes from animals or the industry. The safest way to avoid trans fats is to eat a vegan diet void of any oils.

Okay to this point I have talked about refined oils and trans fat. But what about coconut oil and olive oil? Aren’t they supposed to be healthy? Read on and find out.

Cold-pressed Olive Oil And Coconut Oil Are Good For You, Right?

Most of the studies on the adverse effects of olive oil used refined olive oil, not extra virgin. So what did these studies say about olive oil?

Olive oil may cause the same paralysis of your arteries as fast food and cheesecake. It impairs the endothelial function as much as the rest of these high-fat meals. Olive oil isn't far better than eating a sausage or Egg McMuffin.

But what about extra virgin olive? Extra virgin olive oil retains a fraction of the phytonutrients found in the olive fruit. It doesn't induce the same spike in inflammatory markers caused by regular olive oil.

Saturated Fat

  • Saturated fatty acids consists of chains of only single bonds
  • Saturated fat is solid at room temperature, which is why it is also known as "solid fat"
  • Poultry and fish have less saturated fat than red meat
  • Common in coconut oil, palm oil, cocoa butter,butter, margarine, cakes, cookies, milk cheese, meat, or desserts

Cold pressed olive oil may have more of a neutral effect, compared to butter. Butter has a harmful effect on your body that can last for up to six hours.

There is a large study that examined the link between olive oil and heart attacks.  They found that virgin olive oil may be better than regular olive oil.

But neither reduced heart attack rates after controlling for healthy dietary behaviors.

Olive oil in a bowl

Olive oil is a calorie dense liquid without any nutrients

Eating olive oil is like going from worst to bad. It is still a poison for the body and is a calorie dense liquid with little nutritional value. 1 cup(2.4 dl) of olive oil contains a whopping 1909 calories.

Many praise coconut oil as a health food. It has a lot of saturated fat and is not much better than butter. It is as harmful as butter when it comes to our cholesterol.

But didn’t research show the Mediterranean diet is healthy? They used a ton of olive oil and thrived. Well, let's find out!

The Heath Benefits Of The Mediterranean Diet

People on the  Mediterranean diet eat more vegetables than the Standard American Diet. Recent studies show that the Mediterranean diet reduces several health risk factors. These include heart disease, cancer, brain disease, and death.

The famous Lyon Diet Heart Study compared this diet to the SAD diet. In this study, they randomized 600 patients who had their first heart attack into two groups.

The control group got no dietary advice. They then told the other group to eat a Mediterranean-type diet.

Mediterranean Diet

The Mediterranean diet is healthier than the Standard American Diet

The Mediterranean group ate more bread and fruit. They also consumed less meat, butter, and cream. Other than that, there were no significant changes in wine, olive oil, or fish consumption.

After four years, the control group had 44 individuals with a second heart attack. But only 14 suffered another attack in the group that changed their diet.

So they reduced the chance of having a heart attack from 4% down to 1%. Their disease progressed a lot less than the regular diet group by about four times .

Unsaturated Fat

  • Unsaturated fat is liquid at room temperature
  • It's divided into:
  • Monounsaturated fat: Sources include avocado, nuts, and vegetable oils, such as canola, olive, and peanut oils
  • Polyunsaturated fat: Common in safflower-, sunflower-, sesame-, soybean-, and corn oils
  • Polyunsaturated fat is also the primary fat found in seafood.

But is it still the healthiest food you can eat? Or is an high carb low fat diet better?

The Amazing Results Of A Low Fat Vegan Diet In Heart Patients

Dr. Caldwell Esselstyn is the author of the book Prevent and Reverse Heart Disease. Esselstyn published a case series of 198 heart patients. He made them switch to a whole plant diet with no animal products or oils.

Of the 198, 177 stuck to the diet, whereas the other 21 quit.What happened to the 21 patients who jumped the wagon? More than half suffered from heart problems within four years.

They either had a fatal heart attack, needed angioplasty, or a heart transplant. Of the 177 who stuck to the plant-based diet, only one had a major incident after the same period. That's less than 1% recurrence.

The Mediterranean diet may be better than the SAD diet because they eat more plants. So, improvements in health may be in spite of, rather than because of the oil.

Vegetable oils are bad because they are in liquid form. But what happens if you eat whole foods before they become oils? Is it better for your health?

Are Nuts Better Than Olive Oil?

A Spanish study wanted to examen the effect of replacing refined olive oil in people's diet.  They created three groups. One group ate refined olive oil, the other one extra virgin olive oil. The third group replaced oils with almonds and walnuts.

They wanted to know the risk of heart disease after a month on each food plan. The only difference in each diet was the main source of fat. So what were the results?

The people in the nut groups did much better than the other groups. They dropped their total cholesterol about 7%. Knocking about twenty points off their bad cholesterol.

The extra virgin olive oil did somewhat better than the refined olive oil. But nuts and seeds remained the best source of fat.


Eating almonds in its whole state is much better than consuming oils

So if you want to get fat the healthy way then eat the food in its whole solid state instead consuming it as an oil. If you like olive oil, eat olives.

Instead of using flaxseed oil buy flaxseeds. Replace sunflower oils or others seed oils with sunflower seeds and so forth. But if you don't eat vegetable oils or animal products won't you get too little fat?

Almost everything we eat has fat in it. It's difficult to be deficient in fats, and many people get far too much. If you are eating a plant-based diet, then getting enough fat is not an issue.

Much like you get all the protein you need from eating plans, you will get plenty of fat. There is loads of fat in nuts, seeds, and avocado.

You don’t need to add much. If you have heart disease, type 2 diabetes or are overweight, then avoid high-fat plant foods.

Okay, so I convinced you that oils are bad. But how do you cook your food if you can’t use oils? That’s a great question.  Let's summarize what we learned today and then find ways to replace oils in your cooking.


All oils are processed food.

Oils contain a lot of calories and little nutritional value.

Refined oils follow a long process before they make the oil. 

Olive oil and coconut oils are usually cold pressed through a mechanical process to make the oil.

Vegetable oils lead to more heart disease, diabetes, and cancer.

Seeds, nuts, and avocado in its natural state are beneficial for your health in moderation.

Okay, so here is how to remove cooking oils from your diet and become healthier.

So if you have vegetable oils and are not using it for your skincare or others reasons, remove them now.

Use the following methods to replace oils in your cooking.

1. Use water instead of oil

One easy way to fry without oil is to replace it with water. I have tried it myself, and the food doesn't stick if you use enough liquid.

Another way to succeed is to buy a good non-stick pan. Use one with a non-toxic ceramic coating or similar.

2. Waterless cookware

A second way to cook without oil is to buy waterless cookware. Waterless cookware is unique cookware where you cook the food with almost no water. 

The cookware cooks the vegetables in their liquid. The outer layer consists of surgical stainless steel. Waterless cookware usually has a five ply metal layer and extra thick bottom.

To cook with them, you have to fill the casserole to at least two-thirds. You then heat the food on medium heat. When the pan starts to whistle, or you reach 158 F °(70 C °), you turn the heat to low.

Cook according to the instruction manual. After a couple of minutes, your vegetables should be soft without using any water or oil.

3. Steam vegetables

You can also steam your vegetables instead of frying. To steam vegetables, please follow these instructions:

1. Cut the vegetables into uniform bite-sized pieces, the way you plan to serve them. Smaller pieces will cook quicker.

2. Add an inch or two (2.5-5cm) of water to your saucepan. Insert the steamer basket. The water should be under the basket. Pour out some water if necessary.

3. Bring the water to a boil over high heat. When you hear the water bubbling and see steam starting to emerge from the pot, it's ready.

4. Add the vegetables, cover and reduce the heat.

5. Check the food after a few minutes.

The vegetables are ready when they are tender.

4. Pressure cooker

A pressure cooker uses steam to cook food. A sealed pot, with a lot of steam inside, builds up a high pressure. Cooking with a pressure cooker helps to cook the food faster.

5. Bake your food

Use a parchment paper when you bake your food.

If your baking needs oils replace it with the following things:

Applesauce, vinegar, mashed bananas, mashed potatoes, mashed pumpkin, tomato sauce, etc.

6. Airfryer

An Airfryer allows you to prepare food using hot air. So now you can enjoy crisp French fries without using oils. With this appliance, you can fry, roast, bake or grill all kinds of delicious food.

Philips is a good brand.
