The dietary laws in the Old Testament were given to the Jews. They were part of the covenant God made with the nation of Israel.
The Bible says that God has made a new covenant / New Testament based on the death of Jesus Christ who died as a sacrifice for sin:
Heb 10:19 Therefore, brethren, having boldness to enter the Holiest by the blood of Jesus,
Heb 10:20 by a new and living way which He consecrated for us, through the veil, that is, His flesh,
Christianity is based on the death burial and resurrection of Jesus not on the old covenant God made with Israel.
God shows Peter the old has passed away in Acts 10:9-13.
Answer 1 - Concerning Christianity in General
Yes. There are absolutely no dietary restrictions within Christianity, despite its roots in Judaism (which does have a restriction on pork).
The reasons for this are many, but as an example, Peter had a vision from God where all foods were now permissable:
Acts 10:10-15 - Then he [the apostle Peter] became very hungry and wanted to eat; but while they made ready, he fell into a trance and saw heaven opened and an object like a great sheet bound at the four corners, descending to him and let down to the earth. In it were all kinds of four-footed animals of the earth, wild beasts, creeping things, and birds of the air. And a voice came to him, "Rise, Peter; kill and eat." But Peter said, "Not so, Lord! For I have never eaten anything common or unclean." And a voice spoke to him again the second time, "What God has cleansed you must not call common."
There are other references too:
In 1 Timothy 4, Paul writes of "departures from the faith" and "doctrines of demons" that would pervert the true church. Among these false doctrines are commands to abstain from some foods:
1 Timothy 4:3-5 - ...and commanding to abstain from foods which God created to be received with Thanksgiving by those who believe and know the truth. For every creature of God is good, and nothing is to be refused if it is received with thanksgiving; for it is sanctified by the word of God and prayer. Look again. For those who BELIEVE and KNOW the TRUTH, NOTHING IS TO BE REFUSED if it is received with prayerful thanksgiving.
Also, Christ himself said that it is not what goes INTO a man's mouth that makes him unclean, but what comes OUT of it (lies, slander deceit etc).
So Christians are not under ANY dietary restrictions. Christians could even eat meat sacrificed to idols if doing so didn't violate their conscience (1 Corinthians 8)!
The only slight restriction is that some Christians (notably Roman Catholics) refrain from eating meat on Fridays, in commemoration of Christ's crucifixion , usually eating fish instead. However this semi-fasting is not a requirement of Christianity - merely a custom that has sprung up among some Roman Catholics.
Answer 2 - Concerning Eastern Orthodoxy
The answer above is informative and is well referenced. There is no doubt about its authenticity. With full respect of the arguments above, I just like to add one side point. I have some Orthodox Christian friends. They state that they are forbidden from eating pork. This a cultural attitude rather than a strict religious requirement. In the Islamic World, eating pork is seen as a cultural negative and therefore many pork-containing Pre-Islamic Christian dishes in the Islamic World have simply disappeared in much the same way that Indian pork-containing dishes have simply disappeared do to centuries of Islamic control prior to British colonialism.
Copts, Maronites, and Assyrians do not normally eat pork in their respective countries, but are emphatic that eating pork is religiously acceptable and have no issue with performing these actions in the West. Please see the Related Links below for a further discussion on this.
Answer 3 - Concerning Christianity in General
Yes. In the Book of Acts, Peter had a vision of a sheet descending from heaven carrying all kinds of food that was once not permitted, when he heard the voice of God saying that from then on all food would be permitted. Therefore, for the Christian all food is permitted - no kind of food is forbidden. However, in some branches of the Christian Church there are some restrictions that are a matter of custom rather than 'rules'. For example, those in the Salvation Army are not permitted to drink alcohol (for social reasons as they do much-needed work among alcoholics) , and some Roman Catholics eat no meat on a Friday (as Jesus was crucified on a Friday and they mark it as a day of fasting) but, as stated, these are customs rather than Christian rules.
There are those, such as the writer of the answer below, who are confused by Jesus' teaching. They cite the fact that Jesus upheld the prohibition against pork because he had come 'not to abolish the Law'.
However, this is untrue. If one used this logic, then Jesus doing healings on the Sabbath (which he did) would immediately abolish the Law. His eating of food without ritual washing (which he did) would immediately abolish the Law. His fraternising with women (which he did) would immediately abolish the Law. His talking to a Samaritan woman who was living with someone not her husband flouted the Jewish Law on three accounts. His command that the disciples should regard the Cup of wine at the last Supper as his blood flouted the Jewish Law so much because of the total and absolute ban on blood consumprion by Levitical Law. The list goes on...
The problem was that the Laws were made for humanity but humanity had twisted them making them a burden. God's original Law was that we were to love God and to each other. This was the essence of the 10 commandments. Hence Jesus' comment that he wished to fulfill the Law meant just that; to free us up from the petty rules and regulations that covered Jewish culture, in order that we should love God in the way He intended. And that extended to eating pork.
If the following answer was true, then Christians would not only not be able to eat pork, they would have to be circumcised, ritually wash before each meal, never have blood transfusions in hospital, go to church on Saturdays, never eat shellfish, never wear clothes made from two kinds of cloth, and - of course - all men would have to be circumcised. So to suggest that Jesus, out of all these petty rules, and more, singled out the prohibition on pork alone, is clearly absurd.
Answer 4As a Christian, I am to imitate (meaning of disciple) the life of Christ. To this extent, I follow His dietary customs - abstaining from pork, shellfish, etc as found in the Dietary Laws of Judaism (primarily Leviticus 11 and Deuteronomy 14).
The main Scripture used to say this law is no longer in affect has most pointing to Peter in Acts 10 and his dream. Read properly in its full context, the reader quickly learns the dream was telling Peter the Gentiles (viewed as unclean) are now included (all cleansed by Christ) in God's Plan and has nothing to do with dietary laws.
Traditional Jews do not eat pork at any time. It is forbidden in the Hebrew Bible (Deuteronomy ch.14).
Jews and Muslims do not eat pork because it is considered haram (forbidden) in their respective religious beliefs. In Judaism, the prohibition against pork consumption is outlined in the Torah, while in Islam, it is forbidden in the Quran. Both religions consider the consumption of pork to be impure and spiritually detrimental.

Pork.
It is forbidden explicitly in Quran, God holy book, to eat pork or meat of pig. It is a direct and explicit God command, as mentioned in Quran, that is not subject to justification or debate. It should be followed as sign of God obedience even if there is no apparent justification for it. However, it is proved recently that Pork meat has negative impacts on your health. It is worthy to mention that Pork is also forbidden in Judaism and Christianity although the Christian church allows its eating. Refer to related question for more information.
