The issue isn't really about pigs. But about IQ.
The people who don't eat pigs mostly do so because their bloodthirsty barbaric god forbade them to do so. It's haram. It's not kosher. Whatever. Bad juju. Bad kharma. Some other nonsense.
Now this obviously didn't originate from their dark and backwards god, which is fictional. It originated in their history as a way of teaching poor people not to eat things that would kill them. Probably a rule that originated 2000 odd years ago.
But they still follow it today.
Now 2000 years ago eating a pig may very well have been dangerous enough for these rules to be required. That's not in dispuite. But obviously these issues have been solved by now.
By intelligent peoples. With industry, and science, and insight, and intellect.
Which if the various subhumans had in great quantities amongst their population would have precluded the rules for the religious dogma anyway.
But even though they know its safe they are still trapped in their millenia-old rules.
Because they are not inquisitive. Intelligent. Industrious. Insightful. Or scientific.
Imagine you have a tribe of idiots and a tribe of western europeans. Both don't understand the world around them really. And you need them to not do something. So you invent a magic man in the sky and say HE said not to do the thing. Tell them stories about how mighty and powerful and wise he is.
One groups accepts the rule and never deviates from it. The other, even if they accepted the rule at it's creation, would eventually through discovery and experementation realise that it's BS. You can eat pork if you want. You just have to cook it properly. One group is humans, the other are animals in human shape.
