Yeah, as I understand, these were attempts at guidelines for avoiding diseases, because e.g. pork goes bad very quickly.
But we didn't properly figure out how diseases spread until well past the Middle Ages, so that's why they seem to so random...
It also didn't help that in ancient times pigs apparently had a propensity for digging up graves and eating corpses... (Not 100% sure if this is true, but my high school teacher was Jewish and mentioned that as one of the main reasons for why pork isn't kosher)
