What are the reasons for the prohibition of pork in Islam, especially with studies claiming it is healthy and contains a lower fat percentage than other meats?

Previous fatwas have pointed out the harms of eating pork. What I have read in some magazines that it is one of the healthiest meats is contradicted by studies that have shown its many harms. There is a research supported by images on the website of the International Commission on Scientific Signs in the Qur'an and Sunnah, and information on this topic can be found on the website of Al-Iman University. There are also fatwas that outline the foundations for inviting Christians to Islam.
