There is no agreement on the purpose of Kashrut. It's not explicitly stated in the Torah. It could be an arbitrary test of faith, to seperate Jews from other cultures, a guideline for healthy eating, or other reasons unknowable.

It's not that simple. Kashrut and Halal laws overlap in some areas but there's nothing hard and fast like "Kosher = Halal."
