In regards to eating unclean foods, God very clearly states several times that this was an abomination to them - not to God.

Leviticus 11:10-13 And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you: They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcases in abomination. Whatsoever hath no fins nor scales in the waters, that shall be an abomination unto you. And these are they which ye shall have in abomination among the fowls; they shall not be eaten, they are an abomination: the eagle, and the ossifrage, and the ospray,

Leviticus 11:20 All fowls that creep, going upon all four, shall be an abomination unto you.

Leviticus 11:23 But all other flying creeping things, which have four feet, shall be an abomination unto you.

Leviticus 11:41-42 And every creeping thing that creepeth upon the earth shall be an abomination; it shall not be eaten. Whatsoever goeth upon the belly, and whatsoever goeth upon all four, or whatsoever hath more feet among all creeping things that creep upon the earth, them ye shall not eat; for they are an abomination.

A couple of verses don't specify who is in view - but the overall passage does various times.
