Why are seed oils problematic?

Seed oils are considered problematic by several health experts due to a range of concerns:

1. Omega-6 Fatty Acids: Seed oils, such as canola and soybean oil, are high in omega-6 fatty acids, which are pro-inflammatory when consumed in excess. A high ratio of omega-6 to omega-3 fatty acids can promote chronic inflammation, tied to numerous health issues, including chronic diseases 1 2.

2. Oxidation and Free Radicals: Seed oils are easily oxidized, leading to the formation of free radicals which can cause cellular damage. This oxidative stress is linked to various diseases, including cardiovascular disease and possibly cancer 1 2 3.

3. Impact on Metabolism and Mitochondria: These oils can interfere with metabolic functions and are associated with mitochondrial dysfunction. This includes issues with satiety, hunger signals, and overall metabolic health 2 4.

4. Toxic Byproducts: The processing of seed oils involves high heat and chemicals, which can introduce harmful substances like benzene, phthalates, and heavy metals into the oils. These substances are known for their carcinogenic and endocrine-disrupting properties 4 5.

5. Cardiovascular Health: Epidemiological studies often fail to consider populations that don't consume seed oils. When looking at populations without seed oil consumption, there is a notable absence of many chronic diseases found in Western populations that do consume these oils 6.

Overall, reducing or eliminating seed oils from the diet could help mitigate these risks and improve general health outcomes.
