God set down dietary laws in the Law.
Jesus fulfilled the Law and thus, did away with the provisions of the Law (dietary restrictions, animal sacrifice, a human high priest, etc).
The dietary and sacrificial prescriptions of the Law are specifically removed in the New Testament books of Acts, Galatians, and Hebrews.
The New Testament continues to call homosexual relations a sin and an abomination.
But not Jesus. In fact, He never said a word on the subject. He had plenty to say on divorce, though, and that practice is promoted by the government. Go figure.
