In spite of what many believers think, the Bible does not, in the Old or New Testaments, abolish or do away with God's laws about foods that he created either to be eaten (clean) or avoided (unclean).
In the seventh chapter of Mark, the dispute between the Pharisees and Christ did not concern, at all, what could or could not be eaten. It involved whether his followers could eat a few grains of food without having to wash, ceremonially, their hands several times! Peter's vision of Acts 10 commonly thought to make all unclean meats clean to eat, was God's way of conveying to bigoted Peter that no human was worth less than others were.
Paul the apostle also upheld the Biblical laws regarding what is good and not good to eat as still being valid for believers (1Timothy 4:1 - 3). He showed that while some things were made for us to ingest others clearly were not.
Clean foods in the Bible are those that, in their natural state, do not harm the human body and which man can use for his nourishment and health. Those considered unclean, however, are those which are unhealthy to consume and poisonous to the body.
Below is a list of various meats and fishes humans have taken upon themselves to consider as food. Please note that this list does not denote every animal on the planet and where it is classified but rather those that humans, somewhere, have tried to use for nourishment.
