 As far as land animals go, pork is generally not the best for us to consume. Spiritually speaking, pigs are designed by nature to clean up garbage. They eat the leftovers and the scraps that we don't want, and God designed them for this purpose to help create manure, to help nourish our plants and trees. The hog farming system is one of the filthiest system of all of our land farm operations, and when we eat pigs, we are taking that pollution and contamination into our bodies. There have also been people who, trying the carnivore diet, found that certain attributes of their bloodwork got a lot worse when they had a lot of pork products, but when they took it out, their blood became normal. Even biblically, it was written that God forbid people not to eat pigs because they were unclean to us. This wasn't an accident or some arbitrary rule. Bottom line, we'll be happier and healthier without it, and if we stop buying it, the food industries will be forced to change and evolve, and so if you're eating meat, I'd recommend sticking with chicken and beef.
