A Little More...
It was also mentioned in the site I was referred to, that avoiding pork was not intended by our Heavenly Father as a health measure. It was said that the laws were merely to keep the Israelites separate from other nations by their customs. But in Exodus 15:26, scripture states:
He said, "If you listen carefully to the voice of the Lord your God and do what is right in his eyes, if you pay attention to his commands and keep all his decrees, I will not bring on you any of the diseases I brought on the Egyptians, for I am the Lord, who heals you."

And Leviticus 14 and 15 at least are clear in giving commands and regulations for quarantine, cleanliness, and health.

There also seems to be a difference in commands of which disobedience is punished, and others that are actually instruction, the ignorance or disobedience of which is followed by natural consequences.
