Most people are not aware of this, but vegetable oils were not originally called vegetable oils. They were originally called seed oils. In order for a person to be able to consume vegetable oils, they all have to be chemically extracted from grain, seeds, or beans. They were given name “vegetable oil” because the word “vegetable” appeared to be healthier when marketing the products (“seed oil, “grain oil”, and “bean oil” just don’t sound as healthy in marketing!). They are literally industrial oils, and were used only as such prior to being utilized in foods beginning in the early 1900’s. Things like animal fats/lard/tallow, fish oil, coconut oil, olive oil, and avocado oil do not have to be chemically extracted to be obtained and consumed. Hence, they have been consumed for centuries.
