Question about the pigs and kosher in Judaism

Shalom aleichem. I’ve heard from a famous local jew talking about a line of thought which I wasn’t familiar. It might be weird at first, but from what I understood, he explains the kosher laws aren’t the “main” reason why jews don’t eat pork, but actually leads to a kind of pre-adamic concept civilization. That people were souless and not spiritual, and commonly reincarnate as pigs, and by eating pork, might be doing a sort of anthropophagy, according to him, referring on jewish mysticism.

Do you guys ever heard of this, or do know the about “movement” it is based on?
I’d like to understand it a bit further.
