Only Four Foods Prohibited
[16:115] He only prohibits for you dead animals, blood, the meat of pigs,* and food which is dedicated to other than GOD. If one is forced (to eat these), without being deliberate or malicious, then GOD is Forgiver, Most Merciful.
*16:115 & 118 The most devastating trichinosis parasite, Trichinella spiralis, (also the pork tapeworm Taenia solium) survives in the meat of pigs, not the fat. More than 150,000 people are infected annually in the United States. See 6:145-146, and Appendix 16.
[16:116] You shall not utter lies with your own tongues stating: “This is lawful, and this is unlawful,” to fabricate lies and attribute them to GOD. Surely, those who fabricate lies and attribute them to GOD will never succeed.
[16:117] They enjoy briefly, then suffer painful retribution.
[16:118] For the Jews, we prohibited what we narrated to you previously.* It was not us who wronged them; they are the ones who wronged their own souls.
[16:119] Yet, as regards those who fall in sin out of ignorance then repent thereafter and reform, your Lord, after this is done, is Forgiver, Most Merciful.
Human-made Dietary Prohibitions
[10:59] Say, “Did you note how GOD sends down to you all kinds of provisions, then you render some of them unlawful, and some lawful?” Say, “Did GOD give you permission to do this? Or, do you fabricate lies and attribute them to GOD?” [10:60] Does it ever occur to those who fabricate lies about GOD that they will have to face Him on the Day of Resurrection? Certainly, GOD showers the people with His grace, but most of them are unappreciative.
[5:3] Prohibited for you are animals that die of themselves, blood, the meat of pigs,* and animals dedicated to other than GOD. (Animals that die of themselves include those) strangled, struck with an object, fallen from a height, gored, attacked by a wild animal—unless you save your animal before it dies—and animals sacrificed on altars. Also prohibited is dividing the meat through a game of chance; this is an abomination. Today, the disbelievers have given up concerning (the eradication of) your religion; do not fear them and fear Me instead. Today, I have completed your religion, perfected My blessing upon you, and I have decreed Submission as the religion for you. If one is forced by famine (to eat prohibited food), without being deliberately sinful, then GOD is Forgiver, Merciful.
Did the Jews have different dietary prohibitions?
[6:146] For those who are Jewish we prohibited animals with undivided hoofs; and of the cattle and sheep we prohibited the fat, except that which is carried on their backs, or in the viscera, or mixed with bones. That was a retribution for their transgressions, and we are truthful.
[4:160] Due to their transgressions, we prohibited for the Jews good foods that used to be lawful for them; also for consistently repelling from the path of GOD.

Dietary Prohibitions
The Quran teaches that God is extremely displeased with those who prohibit anything that was not specifically prohibited in the Quran (16:112-116). The upholding of any prohibitions not specifically mentioned in the Quran is tantamount to idolatry (6:142-152). Such prohibitions represent some other god(s) besides God. If you worship God ALONE, you will uphold His teachings ALONE and honor the commandments and prohibitions instituted only by Him.
The absolute specificity of dietary prohibitions in the Quran is best illustrated in 6:145-146. We learn from these two verses that when God prohibits “meat,” He prohibits “meat” and nothing else, and when He prohibits “fat,” that is what He specifically prohibits. These two verses inform us that “the meat” of pigs is prohibited, not “the fat.” Obviously, God knew that in many countries, lard would be used in baked goods and other food products, and that such usage does not render the foods Haraam (prohibited). The Quran specifically prohibits four meats (2:173, 5:3, 6:142-145, and 16:112):
Say, “I do not find in what was revealed to me
anything prohibited for any eater
unless it is (1) carrion, (2) running blood,
(3) the meat of pigs, for it is unclean, and
(4) meat blasphemously dedicated to other than God.”
If one is forced to eat these
without being malicious or deliberate,
then your Lord is Forgiver, Most Merciful. [ 6:145 ]
