The Law that God gave to Moses prohibited the eating of unclean meat like swine flesh/pork.
Jesus and his disciples did not eat unclean meat since they follow the Law of Moses.
The Muslims also do not eat unclean meat since it was prohibited by God in the Holy Qur'an.
I will quote some passages in The Old Testament and in Jesus' Gospel and the Holy Qur'an forbidding the eating of pork meat.
Torah
Leviticus
11:7 And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he [is] unclean to you.
11:8Of their flesh shall ye not eat, and their carcase shall ye not touch; they [are] unclean to you.
Deuteronomy
14:8 And the swine, because it divideth the hoof, yet cheweth not the cud, it [is] unclean unto you: ye shall not eat of their flesh, nor touch their
dead carcase.
Isaiah
65:3 A people that provoketh me to anger continually to my face; that sacrificeth in gardens, and burneth incense upon altars of brick;
65:4 Which remain among the graves, and lodge in the monuments, which eat swine's flesh, and broth of abominable [things is in] their vessels;
66:16 For by fire and by his sword will the LORD plead with all flesh: and the slain of the LORD shall be many.
66:17 They that sanctify themselves, and purify themselves in the gardens behind one [tree] in the midst, eating swine's flesh, and the abomination,
and the mouse, shall be consumed together, saith the LORD.
Gospel of Jesus
5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven:
but whosoever shall do and teach [them], the same shall be called great in the kingdom of heaven.
Acts
10:12 Wherein were all manner of fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air.
10:13 And there came a voice to him, Rise, Peter; kill, and eat.
10:14 But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean.
15:20 But that we write unto them, that they abstain from pollutions of idols, and [from] fornication, and [from] things strangled, and [from]
blood.
15:29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves,
ye shall do well. Fare ye well.
Holy Qur'an
002.173 He hath forbidden you only carrion, and blood, and swine flesh, and that which hath been immolated to (the name of) any other than Allah. But
he who is driven by necessity, neither craving nor transgressing, it is no sin for him. Lo! Allah is Forgiving, Merciful.
005.003 forbidden unto you (for food) are carrion and blood and swineflesh, and that which hath been dedicated unto any other than Allah, and the
strangled, and the dead through beating, and the dead through falling from a height, and that which hath been killed by (the goring of) horns, and the
devoured of wild beasts, saving that which ye make lawful (by the death-stroke), and that which hath been immolated unto idols. And (forbidden is it)
that ye swear by the divining arrows. This is an abomination. This day are those who disbelieve in despair of (ever harming) your religion; so fear
them not, fear Me! This day have I perfected your religion for you and completed My favour unto you, and have chosen for you as religion al-Islam.
Whoso is forced by hunger, not by will, to sin: (for him) lo! Allah is Forgiving, Merciful.
016.115 He hath forbidden for you only carrion and blood and swineflesh and that which hath been immolated in the name of any other than Allah; but he
who is driven thereto, neither craving nor transgressing, lo! then Allah is Forgiving, Merciful.
016.116 And speak not, concerning that which your own tongues qualify (as clean or unclean), the falsehood: "This is lawful, and this is forbidden,"
so that ye invent a lie against Allah. Lo! those who invent a lie against Allah will not succeed.
002.168 O mankind! Eat of that which is lawful and wholesome in the earth, and follow not the footsteps of the devil. Lo! he is an open enemy for
you.
005.005 This day are (all) good things made lawful for you. The food of those who have received the Scripture is lawful for you, and your food is
lawful for them. And so are the virtuous women of the believers and the virtuous women of those who received the Scripture before you (lawful for you)
when ye give them their marriage portions and live with them in honour, not in fornication, nor taking them as secret concubines. Whoso denieth the
faith, his work is vain and he will be among the losers in the Hereafter.
042.021 Or have they partners (of Allah) who have made lawful for them in religion that which Allah allowed not ? And but for a decisive word (gone
forth already), it would have been judged between them. Lo! for wrong-doers is a painful doom.

It has been mentioned in The Holy Qur'an that God transformed some men into apes and swines; Jesus also when he was casting off demons cast the evil
spirits in a herd of swine.
005.060 Shall I tell thee of a worse (case) than theirs for retribution with Allah ? (Worse is the case of him) whom Allah hath cursed, him on whom
His wrath hath fallen and of whose sort Allah hath turned some to apes and swine, and who serveth idols. Such are in worse plight and further astray
from the plain road.
There were 6,666 demon spirits and the disciples were affrighted;
'Where is your faith? It is necessary that the demon should depart, and not I.' The demons therefore cried: 'We will come out, but permit us to
enter into those swine.' There were feeding there, near to the sea, about ten thousand swine belonging to the Canaanites. Thereupon Jesus said:
'Depart, and enter into the swine.' With a roar the demons entered into the swine, and cast them headlong into the sea.
I just want to know who allowed the eating of pork to Christians? I used to be a Christian and used to eat pork until I became Muslim and learned that
God prohibited it to his people. Never ate pork since.
Peace!
