We have no indication that the proscription was based on ceremonial, or shadowy, issues. As far as we can determine, all of the forbidden categories are so classified because God wanted His people to be healthy and happy.

This conclusion is verified by the findings of modern nutritionists, who have identified many of the "unclean" meats as heavy with deleterious fat or disease elements. In ancient times, God accused His people of destroying themselves for lack of knowledge (Hosea 4:6), and promised freedom from disease if they followed His laws (Exodus 15:26). Why should we continue the destructive rebellion which marked the course of Israel's past?
