The sad thing about this is science reports keep coming out on these animals that the Bible calls unclean and NOT food and how unhealthy they are for us. Yet, if you present this evidence to someone in the church, most likely they will refer to this passage to say it's okay to eat it. If you go back to where God says what animals are food and what aren't food, a lot of the ones that are listed as not food are the "garbage cans" of the wild. They scavenge and clean up already dead things or eat things most people would never dream of eating. Especially pigs. Look up "swine" in your favorite concordance and read all the verses associated with the word.
