Naturally occurring fats include fats that appear in wild-raised meats (which can include organic pasture-raised livestock), fish, and other animal products; in their native form in nuts/seeds; coconuts; and avocados. Minimally processed cold-pressed oils, which are just basically cold ground seeds, are in this list. This also includes unprocessed coconut, cacao, and palm oils.

Industrially-produced fats include most commercial oils (corn, soy, safflower, sunflower, etc.), margarine, any other kind of fake fat. These oils are highly processed with heat and chemicals, which destroys their nutritional value, often changes their molecular configuration, and fundamentally alters their behaviour in the body. I also recommend against saturated fats from industrially raised grain-fed animals. What the animal eats affects its fatty acid profile.

I’ve also dug up some articles citing research saying that LDL cholesterol can be further divided into two parts, large and small LDL, with only small LDL posing a risk to your heart health.

Unfortunately I can’t link to them at the moment, since i don’t know where they are, but they seemed pretty credible to me.

And even on a high-fatty diet that’s even higher in inflammatory fats nothing’s ever come up bad on a doctor’s visit. No high cholesterol levels or triglycerides or blood pressure issues or what have you.
