Seed oils require advanced processing techniques that have only been around for a few decades, a mere blip in the timeline of human evolution. Consuming seed oils introduces substances that our bodies are not well-equipped to handle. Additionally, seeds and nuts contain a high concentration of defense chemicals, which is therefore also found in their oils. While avocado and olive oils are generally considered healthier options, they are often blended with lower-quality oils, so it's important to choose high-quality varieties. Furthermore, avocado and olive oils typically include their seeds (such as the pits of olives and avocados), which may not be ideal either. Personally, I prefer using tallow, lard, butter, and ghee for cooking.

General rule of thumb is to avoid oils that are highly processed and high in linoleic acid because it oxidizes easily which causes havoc in the body. Coconut is a good one, I think avocado too. Olive is fine, but you gotta be careful it's real, there's a lot of olive oils thar are diluted with soybeanoil.
