Yeah. A bit tongue in cheek, utility is to utilon as sin is to sin-on.
It’s like a very immature concept in my head and I’m still trying to map out what’s hiding in there, but it seems useful to me at the moment to figure out what a sin-on is made of and figure out order-of-magnitude type detail about things, as a way of trying to make reasonably consistent choices.
I think salmon is meat, but it might be one of the less bad things (don’t know), and this is something I’ll deliberately examine if it solves some health stuff.
