Is Vegetable Oil Healthy? No It Makes You FAT

Most people assume vegetable oils are healthy for them, but the truth will shock you.

Vegetable oils are thought to be healthy because they are made from vegetables. Duh!

The truth is they are very misunderstood by the general population just like whole grains are.

More studies are coming out finding consuming vegetable oils are very bad for your health and are making you fat.

Putting the wrong vegetable oils into your body can cause inflammation in your gut. It will then spread out into your arteries and nervous system along with the rest of your body.

Vegetable oils can block the enzymes used to help break down fat for energy. This can cause you to gain belly fat and make you gain weight.

Bad vegetable oils are widely used in processed foods because they are so cheap for food manufacturers.

They add them to foods to help prevent mold growth and improve shelf life. Yet at the same time, these food manufacturers are turning healthy foods into ones that cause inflammation.

Vegetable oils can cause intestinal problems such as leaky gut syndrome and immune system disorders.

It’s crazy to think smoking cigarettes is probably better for your health than consuming these vegetable oils.

I’m sure you’ll agree it can be confusing to know if vegetable oils are healthy for you.

Here you will discover which vegetable oils are bad for your health and are causing you to gain weight.

You also uncover the best vegetable oils for your health that will help you slim your waistline and improve your health.

Why Vegetable Oils Are Bad For You

why vegetable oils are bad for you

Vegetable oils have long been thought to be healthy for you. Not only for your weight but also for your heart health.

We’ve been swindled!

This study in BMJ analyzed data from older studies and found the link between vegetable oils and heart health was not as solid as we thought all along.

The researchers found eating too many of these vegetable oils can actually increase your risk of heart disease.

The reason these vegetable oils are so bad for you is they contain high amounts of omega-6 fatty acids.

Eating too many of these omega-6 fatty acids is very bad for you as humans weren’t designed to eat so much of them.

Food manufacturers just started producing vegetable oils a little over 100 years ago. Throughout human existence, we didn’t have access to these heavily processed vegetable oils so our bodies are not accustomed to processing them.

Between the years 1909 and 1999 vegetable oil consumption is now at a thousand times what used to be. In 1909 just 2.7% of your calories came from linoleic acid, but in 1999 7.2% comes from it.

Vegetable oils go through a heavy manufacturing process. Unlike butter and coconuts because they can’t be pressed or naturally separated.

To remove oils from these vegetables and seeds the manufacturers have to use processing, heating, chemicals and toxic solvents like hexane.

Chemically removing, deodorizing and altering these vegetables causes a lot of problems that are harmful to your body.

Even if you go with one of these bad vegetable oils that’s “organic” it will still be high in omega-6s. They are usually more expensive too.

The heavy processing these vegetable oils go through deplete them of phytonutrients.

Food manufacturers use these vegetable oils to increase shelf life for processed foods at the expense of your waistline.

The worst offenders include:

  • canola
  • corn
  • cottonseed
  • soybean
  • sunflower
  • safflower
  • grapeseed

These vegetable oils tend to be very heavily processed. Chemical solvents are used on them.

Refined oils are also more popular because unrefined oils often taste very bad and contain unwanted compounds.

So increased shelf life and better taste make it an easy decision for food manufacturers to put them in their foods.

Omega-6 | Omega-3 Fatty Acid Imbalance

Your body needs the essential fatty acids omega-6 and omega-3s from your diet since we can’t make them on our own.

Your body needs them for vital functions such as your immune system. Your body also needs to maintain a balance between the two of them.

Long ago the omega-6 and omega-3 fatty acid ratio was 4:1 to 1:2 but today it’s more like 16:1 on average.

Ideally, you’d have a 1:1 ratio or at least close to it to maintain a proper essential fatty acid balance.

Studies have found an imbalance of omega-6 fatty acids can cause inflammation and obesity. Balancing it out with omega-3 fatty acids will help to fight inflammation.

The more omega-6s you put into your body the more omega-3’s you’ll need to counteract it.

But just consuming more omega-3s will not be enough. You also need to lower your intake of omega-6s. A good start is to stop eating processed foods and vegetable oils.

omega3 vs omega6

The traditional Western diet is very high in omega-6s and low in omega-3s. This is one of the reasons why the Western world has so many problems with obesity, diabetes, heart disease, depression, and cancer.

Most studies link omega-6s to cancer such as a study out of the University of Western Ontario.

The researchers found saturated fats produced the least number of cancers while omega-6s produced the most. Crazy enough they found polyunsaturated fatty acids stimulated cancer growth while saturated fats did not.

Most of these vegetable oils contain too much linoleic acid. This is a fatty acid that will cause inflammation in your body when exposed to heat.

This will increase oxidative stress when it makes its way to your cell membranes and lipoproteins. Oxidative stress can cause damage to your cells and accelerate aging in your body.

Throughout history, humans have had very small amounts of linoleic acid in the diet, but the modern Western diet contains way too many from these bad vegetable oils.

Healthy vs Unhealthy Fats

Healthy vs Unhealthy Fats

Vegetable oils contain very high amounts of processed polyunsaturated fats.

Since the 1950s many of these vegetable oils have replaced saturated fats in the diet. This has caused a lot more problems than good.

In the 1950s a campaign came out against saturated fats linking them to heart disease and weight gain. In reality, they were good for you all along.

Your body needs healthy fats for rebuilding cells and hormonal production. Good fats should not be avoided.

When you’re eating too many processed polyunsaturated fats it’ll cause your body to use them in cells repairing and creation. You can see how eating these bad fats is affecting you not only in your waistline but on a cellular level.

This will cause inflammation and mutation in your cells that can lead to weight gain, heart disease, and cancers.

The cells in your arteries can begin to clog as the inflammation these heavily processed vegetable oils starts to build up.

These bad vegetable oils make their way to your skin cells and can cause skin cancer. You’ll even be more likely to sunburn just from eating too many of these vegetable oils.

Vegetable Oils Are Liquid Death

Vegetable Oils Have Trans Fats

Trans fats are the worst of their kind. They are unsaturated fats modified by food manufacturers to be solid at room temperatures.

The vegetable oils you’re eating contain mostly heat sensitive polyunsaturated fatty acids. When they are heated they turn into toxic compounds including trans fats.

Margarine was once thought to be very healthy for you. But these hydrogenated oils are horrible for your health and weight.

Trans fats are highly toxic and linked to the increased risk of heart disease, diabetes, cancer, and obesity.

Governments have finally begun taking action against trans fats by banning them in foods. They’re also making food manufacturers significantly lower their content in foods.

Many vegetable oils contain these trans fats even in small amounts.

This study found soybean and canola oils contain 0.56 to 4.2% fatty acids from trans fats.

You really need to reduce the trans fats in your diet to the absolute minimum.

They’re horrible for your health and waistline. I would even go so far as to say smoking cigarettes is better for your health.

Want A Heart Attack?

vegetable oils heart disease

Heart disease is the number one killer in the entire world for both men and women. Even more than cancer.

At one time it was thought saturated fats were the enemy. It turns out they were harmless all along.

Vegetable oils are one of the main causes behind the high amounts of weight gain and the serious health problems associated with it in the Western world.

This study in Epidemiology found the more margarine consumption the more likely people were to have a heart attack. But when they ate more butter the heart attacks would go down.

There are other many studies proving that eating too many of the of these heavily processed vegetable oils will significantly increase your risk of heart disease.

According to this study, people with the highest amounts of omega-6s also have the greatest risk for heart disease.

The inflammation caused by consuming too many omega-6 fatty acids is reason enough to get them out of your diet for good.

Even this study found omega-6s increased the risk of heart disease. While consuming more omega-3’s had a protective effect against them.

Try supplementing with some omega-3 rich supplements like fish oil or Krill oil to fight this inflammation that can cause weight gain and heart disease.

Healthiest Oils For Human Consumption

Bad vegetable oils, also known as “liquid death,” are so heavily processed they’re like putting actual motor oil in your body.

Whenever you have trouble remembering the list of bad vegetable oils just remember the three C’s and the three S’s.

  • corn
  • canola
  • cottonseed
  • soybean
  • sunflower
  • safflower
  • then add in grapeseed

When heavily refined these temperature sensitive vegetable oils destroy the healthy polyunsaturated fatty acids along with their antioxidants. Turning them into zombie mutated ones instead.

You can also swap out these bad vegetable oils for saturated and monounsaturated fatty acids. These include:

  • extra virgin olive oil
  • peanut oil
  • grass-fed butter
  • macadamia nut oil
  • coconut oil
  • palm oil
  • animal fats

The days are gone when it was thought eating fats would not only be bad for you but also make you fat.

Turns out eating the wrong kinds of fats in the form of vegetable oils were the criminals in disguise.

Along with sugar and processed carbs, these bad vegetable oils should be eliminated from your diet.

Your health will improve and your waistline will shrink. You’ll feel incredibly better getting these bad vegetable oils out of your diet for good and replacing them with the good fats.

You can find my complete list of healthiest cooking oils here.

Conclusion

Most of the popular vegetable oils you’ll find at the supermarket today are very bad for your health.

They’ll give you weight gain, depression, heart disease, arthritis, diabetes and even cancer.

Getting rid of these bad vegetable oils from your diet will make a big improvement in your health and your weight.

Instead switch them out for healthier choices of vegetable oils including extra virgin olive oil, coconut oil, and palm oil.

Vegetable oils are not healthy for you and it’s much better to consume natural saturated fats such as those from butter and animal meats.

    Hi Josh. I’m a 26 year old male, Of a thin build. What exercise regime would you recommend to build a lean body. I do not wish to bulk up. Somewhere along the lines of a soccer players body if you get me. I’m already skinny so I think cardio will only have a negative effect on my efforts. Your summer arms workout looks interesting. Any help would be great. Thanks

      Hi Stephanie, I’d recommend my diet and workout program from TThe Flat Belly Formula but I’m also biased 😉 – Just focus on eating more clean and healthy foods to increase your caloric intake. This will make you put on more weight but not a lot of fat. Hope this is what you’re looking for.

    Hi,

    So, sunflower oil is bad for us. Is it still ok to eat raw sunflower seeds? What about pumpkin seeds?

      Raw pumpkin and sunflower seeds in moderation are a great source of many nutrients that you need in your diet for your body to run optimally. Just make sure you stay away from sunflower oil because of the high saturated fat content and omega-6’s.
