The eight industrial toxic seed oils are Canola, Corn, Cottonseed, Soy, Sunflower, Safflower, Grapeseed, and Rice bran.

Omega-6s are found in oils such as corn, safflower, sunflower, soy, and vegetable and products made with those oils. Excess consumption of omega-6s can trigger the body to produce pro-inflammatory chemicals.

What’s wrong with industrial seed oils?

There are six main problems with industrial seed oils, all of which play a significant role in chronic inflammatory diseases.

1. The consumption of industrial seed oils represents an evolutionary mismatch.
2. Eating industrial seed oils raises our omega-6-to-omega-3 fatty acid ratios, with significant consequences for our health.
3. Industrial seed oils are unstable and oxidize easily.
4. They contain harmful additives.
5. They’re derived from genetically modified crops.
6. When industrial seed oils are repeatedly heated (as restaurants do in fryers), even more, toxic byproducts are created.

How are industrial seed oils making us sick?

Industrial seed oils are far from the “healthy” label they carry. A number of chronic inflammatory diseases have been linked to a number of chronic health problems such as:

• Asthma
• Autoimmune disease
• Cognitive and mental health issues such as depression, anxiety, cognitive decline, dementia, and even Alzheimer’s disease.
• Diabetes and obesity
• Heart disease (they are far from being heart-healthy!)
• Gut health issues such as irritable bowel syndrome (IBD) and inflammatory bowel disease (IBS)
• Inflammation
• Infertility
• Macular degeneration
• Osteoarthritis

The best thing you can do for your own health and the health of your family is to get rid of all vegetable oils and margarine from your home.  Simply throw them out. Replace them with saturated fats for cooking and extra virgin olive and avocado oil for dressing.

Summary:

At this point, it should be clear that we want to avoid omega-6 fats in our cooking oil. The following is a good graphic to represent what to avoid.

Oils from tropical plants such as cacao, coconut, and palm are lowest in omega-6, while oils from cold-weather plants such as sunflower and soybean are highest in omega-6 and best avoided.
