There's also an issue of lower fat/connective tissue content in plant-based meats (again, necessary to support joint and muscle recovery). Also, IIRC, the fats and oils in meat hold up better to high-temperature cooking than the ones in meat analogues. Best I can do is go pescatarian (which has its own issues at-scale).
They are processed food. I'm under no illusion that they are healthy.
I won't say I've never had them, but I generally turn my nose up at them and stick with real animal flesh or traditional vegetarian food.
