Don’t disagree that most vegetable oils are superior to animal ones, but I think in this particular case it’s much harder to say.
In general high level meat eaters have higher morbidity and mortality. But hard to tease out all the dietary specifics involved.
For fats we do know, better is monounsaturated (best/good) > polyunsaturated > saturated > trans fats (which are frankly quite bad).
I have so far not come across good study comparisons of specific animal oils vs. vegetable matching carbon chain length, oxidation and cis/trans state; so feel we are lacking data to reasonably understand if there are differences in healthiness of saturated animal oil vs. saturated vegetable oil.
Most animals fats are primarily saturated, whereas there are many healthier vegetable oils like olive, avocado, tree nuts, etc. and for this reason alone vegetable oils are almost always healthier.
Lots of folks get excited about coconut oil because it’s vegetable oil, so it must be good. But it’s mostly saturated fat and hence solid at room temp; also why it has one of the longest vegetable oil shelf lives. In terms of coconut oil healthiness, we would need good study data on this that is so far lacking. I would bet coconut oil is probably not a healthy choice.
Also unclear is if bovine or imposter vegan burger here generates more free radicals when cooked and so on.
