When did kosher food begin?

Kosher laws originate from the Torah. The Bible states that Jews must adhere to a set of dietary restrictions known as kashrut. These laws first appear in the Book of Leviticus, with additional details and interpretations provided in the Talmud and other rabbinic literature. The exact date of the origin of kosher food cannot be precisely determined, as it is rooted in ancient Jewish religious practices. However, the basic principles of kashrut have existed since the time of Moses, dating back thousands of years.
