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:
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:
Researchers studying cancer in mice even suggest 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].
If anyone has a criticism of the idea that vegetable oils are harmful, I would be very interested.
