>less healthy is to use high-oleic sunflower oil or olive oil or avocado oil, and the least healthy is to use classic sunflower oil, corn oil, soy oil or sesame oil, like in this study. Most vegetable oils are linoleic. It is only recently that high oelic cooking oil has become a thing. I'm not aware of how prevelant it is in china. And of course olives and avocados are not vegetables. The study actually represents what vegetable oil is pretty well. The data go back to when HO vegetable oils were not a thing, and I speculate they are still not a thing in china, though I may be wrong. The title is still a bit misleading given that the study is more specific than the conclusion but I think you are overstating the dgree to which that is the case.

Inside the article it is said that the vegetable oil that was used for cooking in most of the studied cases was sesame oil. The most abundant fatty acid is sesame oil is linoleic acid, it is not a HO vegetable oil, so it will be degraded during frying much more than HO oils or than animal fat. So the study has not compared vegetable oils in general as food, in comparison to animal fat, but it has compared sesame oil used in high temperature cooking vs. animal fat. This is significant because pristine vegetable oils are expected to be a healthier food than animal fat, while vegetable oils that have been strongly heated are expected to be a less healthy food than strongly heated animal fat. Therefore any study that compares vegetable oil with animal fat must make very clear which of the 2 cases have been studied.

  >This is significant because pristine vegetable oils are expected to be a healthier food than animal fat, while vegetable oils that have been strongly heated are expected to be a less healthy food than strongly heated animal fat. Not true. Omega 6 is worse than animal fat even not fried. It just isn't part of the study. >it is not a HO vegetable oil Like I said, "HO vegetable oil" is not really a thing in the first place. At the very least it's reasonable to not include it in the plain meaning of vegetable oil.
