In Islam, pork was forbidden for human consumption more than 1400 years ago. The wisdom behind this Divine prohibition was only discovered in the 20th century by doctors and scientists.
The abstention from eating pork is one of the steps taken by Islam to practice hygiene and to attain purity of soul. There is a saying in English that “a man becomes what he eats”. According to physicians and medical experts, pork is a harmful diet. The Qur’an has prohibited the swine-flesh, hence why Muslims would not touch it. The Bible has also forbidden swine-flesh, but Christians but most will still consume it.
The life of a man is a compound of body and soul. Anything, which is harmful for the body, hurts the soul as well.
