multi-post series plausibly arguing that vegetable oil is our biggest health problem from food. _this seems potentially important and shocking/disturbing_

by convention, “vegetable oil” doesn’t include olive, coconut or avocado oil (which seem to be healthier). it’s mostly soy bean oil and seed oil. but beware of egregious fraud:

> Avocado oil is an edible oil extracted from the pulp of avocados, the fruit of Persea americana. It is used as an edible oil both raw and for cooking, where it is noted for its high smoke point. It is also used for lubrication and in cosmetics.
> Avocado oil has an exceptionally high smoke point: 250 °C (482 °F) for unrefined oil and 271 °C (520 °F) for refined. The exact smoke point depends on the quality of refinement and the way the oil is stored.

> A study performed at the University of California, Davis in 2020 determined that a majority of the domestic and imported avocado oil sold in the US is rancid before its expiration date or is adulterated with other oils.[6][7] In some cases, the researchers found that bottles labeled as “pure” or “extra virgin” avocado oil contained nearly 100% soybean oil.[6]

There’s a lot of stuff in the posts. Here’s one quote from [part 3](https://www.jeffnobbs.com/posts/why-is-vegetable-oil-unhealthy):

> Researchers studying cancer in mice even [suggest](https://pubmed.ncbi.nlm.nih.gov/3921234/) that dietary polyunsaturated fats like omega-6 are _required_ in order to induce tumors in mammals. In other words, even when trying to do so, researchers may be unable to intentionally form tumors in lab animals without feeding them fats like omega-6. The same phenomenon is found with liver damage: omega-6 consumption is _required_ for the development of alcohol-induced liver injury, and the severity of the liver damage is correlated with the amount of omega-6 in the diet. Furthermore, replacing omega-6 fats with more traditional fats, like those from coconut, reverses alcohol-induced liver damage, even when maintaining the same level of alcohol consumption [[26](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4808795/)].

**If anyone has a criticism of the idea that vegetable oils are harmful, I would be very interested.**
