Well what about all the allergies to shellfish,as well as pork?Besides hogs are considered the landdwelling garbage disposals,just like shellfish do for the oceans,and catfish serve the same purpose in fresh water.
Besides,if hogs had been intended for human consumpsion,why is the milk highly toxic to all other animals,other than pigs?
Also when one develops certain health problems their doctor restricts their intake of Biblically unclean meats.
Personally gave up eating pork several years ago,interesting a number of personal health issues disappeared shortly threre after.
