Plant based oils often have low oxidation temperatures, and oxidized oils are not particularly healthy. Saturated fats usually have higher oxidation temperatures making them more suited to high temperature cooking.
Peanut oil is a pretty good choice for high heat pan frying. The makeup is really what matters- saturated, polyunsaturated, monounsaturated, etc.
Although for what it’s worth my life got a lot better when I learned roasting, braising, simmering, reductions, etc and stopped trying to pan fry everything.
EVOO, Ghee (from grass fed butter), Coconut oil, Avocado oil, Sesame oil, Tallow, Lard and Butter (from grass fed animal) is all that you should be eating. Everything else belongs to trash bin.
