In what way is Speciesism connected with canibalism by any species?
But regardless, eating humans is unhealthy and thus contrary to evolution. Its the same reason why animals that live for a long time (~100) rarely have many enemies, especially if they are omnivores. Evolutionary, it is better to eat meat that do not had years to build up on heavy metals and toxins.
So to put it to a simple point, regardless of the morality with cannibalism, humans would still not eat other humans. There is no -ism needed to explain why we do not eat sulfur, or drink mercury.
