It could also be a category error: Vegetable seed oils seem to correlate strongly with bad health outcomes. Meanwhile, other oils (e.g. olive oil) with similar levels of the same types of fatty acids have better outcomes. https://www.youtube.com/watch?v=7kGnfXXIKZM https://www.youtube.com/watch?v=7kGnfXXIKZM Is it the type of fat, or the process through which it's extracted, that's most important? I don't know if the answer is as clear as we'd like it to be. Going back to the article: Isn't it possible that the trans fat in question is actually toxic like other trans fats, but in a way that's narrowly beneficial in this circumstance?

> Vegetable seed oils seem to correlate strongly with bad health outcomes. Based on what evidence? Here's a good roundup of our best evidence, and it shows that seed oils improve health outcomes: https://www.the-nutrivore.com/post/a-comprehensive-rebuttal-to-seed-oil-sophistry https://www.the-nutrivore.com/post/a-comprehensive-rebuttal-... Since you like Youtube videos, here's a good talk between Gil Carvalho and Simon Hill that also goes through the evidence: https://www.youtube.com/watch?v=_ri4S7MLu3A https://www.youtube.com/watch?v=_ri4S7MLu3A Another summary of the evidence on seed oils by Layne Norton: https://www.youtube.com/watch?v=L2fSaFnt0FM https://www.youtube.com/watch?v=L2fSaFnt0FM I skimmed your video and it's the same old low-carb narratives with very little evidence cited which should always be a red flag. People who can't point to our best metaanalyses or human health outcome research on something to back their point will generally spin narratives because it's all they have left to do.

  When vegetable/seed oils are turned into solid fats, like shortening or margarine, trans fats (in particular, partially hydrogenated oils) occur. They have only recently been restricted in the US, at least to some extent.

    That's true but it's a separate matter. Yes, vegetable and seed oils can be unhealthy if they are processed into trans fats, but otherwise they can be healthy. Whole Foods, for example, banned trans fats 20 years ago, but they sell many products with vegetable and seed oils, and those are generally healthy.
