Which dietary category prohibits the consumption of both pork and shellfish?

The dietary category that prohibits the consumption of both pork and shellfish is kosher. This practice is based on the dietary laws outlined in the Torah, which dictate specific guidelines regarding what is permissible to eat. In kosher rules, certain animals are considered unclean and therefore prohibited, including pork, which is explicitly mentioned in the scriptures as non-kosher. Additionally, shellfish such as shrimp, lobster, and crabs are also classified as non-kosher due to their categorization as seafood that does not have both fins and scales, which are necessary for a fish to be considered kosher.

These dietary laws are strictly adhered to by those who observe kosher practices, making it an integral part of their lifestyle and faith. In contrast, while other dietary categories impose various restrictions, they do not necessarily include both pork and shellfish prohibitions in the same way kosher does.
