It's a common trope to state bad input taints meat taste but I think it's unproven. I think it's more likely that apex diet concentration of complex organic molecules causes taste differences.

Feed pigs on acorns exclusively, yes you get a specific ?malic? Acid outcome in fat.

Feed sheep on seaweed, same with iodine. Corn vs grass fed beef, same.

But "predators eat trashy meat so their flesh is trashy" doesn't ring true. "Obligate carnivore predators in the feline family process meat differently, and emit proteins into their own flesh" may be a mouthful but it's where I am.

Think swordfish and mercury
