The relevance is that if it was a clear black and white issue like the Sabbath or State of the Dead, it would have been agreed upon early on during the formation of the church.
Now, the Scripture that says the lost will be eating the swine and the mouse does not contradict what I have been saying here. Those that are eating the swine and the mouse have no regard for the health message. They are not concerned about treating their body as the temple of God. They will also be doing all types of other immoral behavior.
What I am talking about is the issue of straining the gnat out or the water. If eating pork made us ceremonially unclean, we would want to go to great lengths to avoid it. However if we avoid it due to the health concerns, than it becomes trivial if there is lard in my beans or pig collagen in my Jell-O.
