Yes it is, it is one of the five books of the Torah תורהThere's much agreement between the Torah and the bible as far as animals to eat and not to eat. In fact, isn't Leviticus (old testament) also in the Torah?
It made sense to me. When one looks at the list without an eye to religion, the list still makes sense because in my mind it eliminates bottom feeders (swine, fish without fins/scales, etc.) The remainders are cleaner animals in general.
I used to adhere to the list for health reasons, rather than religious reasons.
Helth and clean are 2 very important things in our religion.
It is a constant thing in food prepration, befor and afterr eating, when you get up, and go out after visiting the rest room, ect, ect,
The notion "Thara"-טהרה is very dominant!
