Why http://al-Quran.info/6/145/Ne forbids eating pork?

Because curses are realities and according to Quran, apes and pigs are former human beings https://legacy.quran.com/5/60

Curse of God also makes "Zombies":

➡ This - https://legacy.quran.com/56/60-62
➡ That - https://legacy.quran.com/40/11-13

Understanding the two lives and two deaths in https://legacy.quran.com/40/11 with reference to https://legacy.quran.com/56/61

(1) their "life-1" in this world as a human being.
(2) then "death-1" changed their form.
(3) then they live "life-2" in this world with the changed form.
(4) Then they die the "death-2" which is the "departure" from this world to the other world/realm.

So when God cursed some Satans from human beings:

• Some of them became "Apes".
• Some of them became "Pigs".
• Some of them became "Slaves of Taghūt".

That is why eating pork is forbidden in Quran.
