Seed oils, like sunflower, corn, soybean, and canola oil, are ubiquitous in the modern diet. These oils are a major component of ultra-processed foods. There's growing concern about the negative health impacts of consuming these oils, especially once they've oxidized.

What is Oxidation?

Oxidation is a chemical reaction involving the interaction of a substance with oxygen. Seed oils, with their high PUFA (polyunsaturated fat) content, are especially prone to oxidation. This oxidation process can happen due to factors like heat, light, and exposure to air. Oxidized seed oils produce harmful compounds like free radicals.

Oxidation and Inflammation

Free radicals from oxidized seed oils can trigger inflammation within the body. Inflammation is a natural immune response, but chronic, unresolved inflammation is linked to various health problems including:

  • Heart disease: Inflammation can contribute to plaque buildup in arteries.
  • Autoimmune conditions: Conditions like rheumatoid arthritis may be exacerbated by chronic inflammation
  • Cancer: Inflammation may increase the risk of certain cancers.
  • Metabolic disorders: There's a link between inflammation and issues like obesity and type 2 diabetes.

Protecting Yourself

To reduce your exposure to oxidized oils and associated inflammation:

  • Limit processed foods: These are often a major source of oxidized seed oils.
  • Choose healthy fats: Opt for olive oil, butter, tallow, ghee, or coconut oil, which are more stable.
  • Store oils properly: Keep oils in a cool, dark place and in tightly sealed containers.
