Seed oils are being consumed every day if you use common cooking oils, eat pre-packaged foods, or eat out at restaurants.

Although seed oils have several health benefits, they are not without their dangers, as they are high in saturated fat, which can lead to heart disease and type 2 diabetes if consumed in excess. The ample amounts of data suggest that they are harmful to long-term intake in the proportions most people eat today.

The intake of seed oils is also the number one contributor to the obesity epidemic, which harms our health. Here, it is essential to note that seed oils are highly processed and contain high levels of Omega 6 fatty acids which can lead to inflammation in the body. Seed oils may also be linked to causing cancer in the human body.

However, it’s important to note that this research is still relatively new, and more studies are needed to confirm these potential health risks.

Let’s dive deeper and learn more about seed oils, their uses, the potential health risks, and some alternatives to them.

WHAT ARE SEED OILS?

Seed oils are oils extracted from the seeds of plants and are typically used in cooking or as a food ingredient. They can also be found in some cosmetics and skincare products.

WHAT ARE THEY USED FOR?

Seed oils are used in various products, including cooking oil, salad dressing, and margarine. They are also used in industrial applications, such as lubricants and paints.

Seed oils are generally considered to be healthy, but there are some concerns about their safety. Some research suggests that consuming seed oils may increase the risk of certain diseases, such as cancer and heart disease.

TYPES OF SEED OILS:

There are a few different types of seed oils that are commonly consumed.

These include:

  • canola oil
  • soybean oil
  • cottonseed oil
  • grapeseed oil
  • sunflower oil

Each of these oils has a different effect on the body and come with risks.

WHICH SEED OILS ARE THE MOST DANGEROUS?

1. Soybean oil:

Soybean oil is a common seed oil and is one of the most dangerous seed oils to avoid. It is high in unhealthy omega-6 fatty acids, which can promote inflammation in the body. Additionally, soybean oil is often highly processed and refined, which contains harmful chemicals that can damage your health. Although it’s too dangerous, its intake is increasing daily as, since 1909, soybean oil alone has increased 1,000-fold in the United States. It is used in many processed foods, as well as being sold as a cooking oil.

Soybeans are often genetically modified (GMO), which means that they have been altered at the genetic level by companies such as Monsanto. GMO soybeans have been linked to various health problems, so it’s best to avoid them if possible.

2. Corn oil:

Like soybean oil, corn oil is also high in omega-6 fatty acids. These fatty acids can promote inflammation and other health problems. Corn oil is often highly processed and refined, which may contain harmful chemicals that can damage your health.

3. Cottonseed oil:

Cottonseed oil is another dangerous seed oil commonly consumed but must be avoided. It contains many omega-6 fatty acids, which can cause inflammation. Additionally, cottonseed oil is often highly processed and refined, which may contain harmful chemicals that can damage your health. It is usually found in processed foods, as well as being sold as a cooking oil. Cottonseed oil has been linked to an increased risk of cancer because it contains high levels of gamma-linolenic acid (GLA).

4. Canola (rapeseed) oil:

Canola oil is one of the most popular seed oils. It is another dangerous seed oil to avoid because it is high in unhealthy omega-6 fatty acids. These fatty acids can promote inflammation in the body when consumed in large amounts. Additionally, canola oil is often highly processed and refined using harsh chemicals and solvents, which may contain harmful chemicals that can damage your health if consumed regularly. Allergens and heavy metal risks are also associated with canola oil. It is used in a variety of processed foods and is also sold as a cooking oil.

Apart from these, grapeseed oil, rice bran oil, safflower oil, and sunflower oil are also dangerous. Even grapeseed safflower and sunflower contain the most linoleic acid among the seed oils. Linoleic acid is found to be the culprit for several diseases.

WHY ARE SEED OILS DANGEROUS, OR WHAT ARE THE HEALTH DANGERS OF CONSUMING SEED OILS:

Seed oils are dangerous for several reasons. There are mentioned a few health dangers of consuming seed oils that you should be aware of.

  • Inflammation-causing: First, they are high in omega-6 fatty acids. This can lead to inflammation in the body and has been linked to several chronic diseases, such as cancer, obesity, and heart disease.
  • Immunosuppressive: According to studies, linoleic acid in seed oils is also harmful to the immune system. If seed oils are given to critically-ill patients, they further deteriorate their health.
  • Atherosclerosis:  Seed oils are often highly processed and refined. This means that they can contain harmful chemicals and toxins that can damage your health. Processing makes the oil oxidized, and oxidized low-density lipoprotein is linked with atherosclerosis. Seed oils are typically high in unhealthy saturated fats. These fats can elevate your cholesterol and cause heart disease. Research suggests that oxidized linoleic acid byproducts resulting from the heating of linoleic acid during cooking increase oxidative stress or cellular damage and larger cardiovascular lesions. Lower levels of good cholesterol and impaired glucose metabolism result from regular and long-term consumption of linoleic acid in seed oils.
  • Diabetes: a cell study in 2006 found that linoleic acid in seed oils caused more plasma membrane loss and DNA fragmentation in insulin-secreting cells compared to omega-3 EPA, oleic acid, and stearic acid. This suggests the negative effect of seed oils on insulin-secreting cells in people at risk of diabetes or those who already have diabetes.
  • Less nutritional value: seed oils are highly processed and refined, which strips them of many of their natural nutrients and antioxidants.
  • Digestive issues: Another problem with seed oils is that they are often rancid when they reach the shelves. This is because they’re exposed to light and air during processing and storage, which causes them to oxidize. Rancid oils contain harmful compounds that can damage your health. Rancid oils can cause digestive issues and are linked to chronic diseases like cancer.
  • Obesity: seed oils are often used in processed foods. These foods are typically high in calories and low in nutrients, which can lead to weight gain and other health problems. And simply consuming these oils leads to weight gain because they are high in calories and have little nutritional value. In a study, increased linoleic acid consumption resulted in 16% more weight gain than the olive oil group. A 2017 study found that a 22.5% linoleic acid-based diet caused increased body weight gain, increased insulin resistance, and decreased activity levels compared to the 1% linoleic acid-based diet.
  • Damage the reproductive health: according to a 2010 study, linoleic acid in seed oils interfered with the maturation of egg cells and inhibited early development of the embryo, suggesting that the increased consumption of linoleic acid has some association with declining fertility rates.
  • Impaired neurological development and Alzheimer’s disease: a 2008 study found that high intake of omega-6 fatty acids as part of early infant nutrition is linked with poor neurodevelopment. Another study in 2017 showed that increased dietary intake of linoleic acid for six months led to increased weight gain, impairments in working memory and brain structure, and the development of beta-amyloid plaque in the brain compared to the control group.
  • Cancer: observational studies have reported omega-6 fatty acids to be linked with tumor growth promotion and, more importantly, with lung and breast cancer. Although 1-2% of the daily calorie intake of linoleic acid and omega-6 fatty acids is required and alright but too much regular consumption is hazardous for health. Studies have demonstrated increased mammary tumor growth rates with an increased linoleic acid intake of up to 10% of energy intake. Also, an increased mammary tumor mass was found.

Here’s what doctors and researchers have to say about seed oils:

  • Dr. Mary Enig, Ph.D., renowned researcher, and nutritionist, said this about seed oils: “They [seed oils] are loaded with toxic compounds that promote inflammation in the body.”
  • Dr. Cate Shanahan, family physician and author of Deep Nutrition, says that seed oils are “parent compounds for a whole host of industrial chemicals that have never been tested for safety in humans.”
  • Dr. Artemis Pishiaras, MD, warns that seed oils can cause “gut dysbiosis, weight gain, diabetes, cancer, heart disease…and even death.”

These are just a few experts who have spoken about the dangers of consuming seed oils. If you still need convincing, consider this: seed oils are some of the most processed and chemically-altered foods on the market today. They’re also high in omega-6 fatty acids, which promote inflammation in the body. So if you want to improve your health, it’s best to avoid these oils altogether.

So, bottom line? Avoid consuming seed oils at all cost and look for alternative safe options.

HOW DO I AVOID CONSUMING SEED OILS?

Considering the possible risks of consuming seed oils, consider limiting your intake or avoiding them altogether.

There are a few things you can do to avoid consuming seed oils.

First, be aware of the seed oils high in omega-6 fatty acids and work on reducing them from your diet.

Try to avoid processed foods that contain seed oils

Another way to prevent consuming seed oils is to cook with healthy fats instead that have a good content of heart-healthy monounsaturated fats. Good options include olive oil, coconut oil, and butter. This will help you reduce your overall intake of omega-6 fatty acids.

Have enough omega-3 fatty acids in your diet as they are anti-inflammatory and can aid in offsetting the effects of omega-6 fats. Good sources of omega-3s include fish, flaxseeds, and chia seeds. By increasing your intake of omega-3s, you can help balance your omega-6 to omega-3 ratio and reduce your risk of chronic disease.

Read the food labels carefully and choose only those products that don’t contain seed oils in their list of ingredients, or buy an organic product that does not use any seed-based oil in its production.

In short, the best way to avoid seed oils is to eat a healthy diet. Eat whole, unprocessed foods, such as fruits, vegetables, and lean protein. Avoid processed foods, especially those that contain seed oils. When cooking at home, use healthy fats, such as olive or coconut oil.

WHAT ARE SOME ALTERNATIVES TO SEED OILS?

A few different types of oils can be used as an alternative to seed oils.

These include:

  • Coconut oil
  • Olive oil
  • Avocado oil
  • Walnut oil
  • Macadamia nut oil

Each of these oils has unique benefits and drawbacks, so it’s essential to choose the one that’s right for you.

Olive oil is a much healthier option and a good choice for cooking, as it’s relatively stable at high temperatures. It’s rich in healthy monounsaturated fats and antioxidants, which have been shown to protect against heart disease and other chronic conditions.

Coconut oil is high in saturated fat and should be avoided if you’re trying to lose weight. However, it can help treat skin conditions like psoriasis and eczema.

Avocado oil is another option similar to olive oil in terms of its nutrient profile. It’s also a good choice for cooking, as it has a high smoke point.

Walnut oil and macadamia nut oil are excellent choices for those looking to boost their intake of omega-3 fatty acids. These oils are also relatively stable at high temperatures, making them suitable for cooking.

THE WRAP-UP:

Consumption of seed oils is a significant health risk that most people are unaware of. The good news is that it’s easy to avoid consuming these oils. There are many seed oils, but the most common ones include soybean oil, corn oil, canola oil, and cottonseed oil. All these oils are extracted from a plant’s seeds and are linked to various health problems such as chronic inflammation, obesity, and cancer.

The best way to avoid consuming seed oils is by choosing products that do not contain them in their list of ingredients or by buying organic products which do not use any seed-based oil in their production process. To avoid consuming seed oils, we must read food labels carefully and eat a well-balanced diet based on healthy, unprocessed foods.

The Meta-Center’s staff follow our internal super human disciplines which I created approximately 7 years ago.  These disciplines are many, but one of the bullet points is to completely eliminate all seeds oils from the diet.  Based on your questions, comments or as time goes on, we may get into the other 20+ protocols.
