IF Jesus had declared the distinction of clean and unclean foods were over, Peter would not have reacted the way he did in Acts 10:9 - 18, Acts 11:5 - 18 where Peter had to overcome his phobia of Gentiles as an unclean race to dismiss as unclean. Peter well understood not to eat unclean foods as did all Jews.
Lastly remember the reason we all die? Lust for an apple in the Garden of Eden. We have to control our appetites for only clean things. God has rules.
Bob , not really sure why this is a discussion topic if you are a non Jew.
We all know that Jesus freed His followers from the Old Testament food laws in Leviticus .
That’s not even an issue for a Christian.
