Here's a breakdown:
* Kashrut: The Jewish dietary laws are known as kashrut. These laws dictate which foods are permissible (kosher) and which are forbidden (trefah) for Jewish people to consume.
* Treifah: This word specifically refers to foods that are forbidden by kashrut. It's a broader term than "non-kosher" and encompasses a range of forbidden foods, including:
* Meat from non-kosher animals: This includes pork, shellfish, rabbits, and other animals that are not ritually slaughtered or lack cloven hooves and chew cud.
* Mixing meat and dairy: Jewish law forbids eating or preparing meat and dairy together, including utensils used for each.
* Blood: Blood is considered trefah and must be drained from meat before consumption.
* Certain insects: Specific insects are considered trefah.
* Certain birds: There are specific birds that are forbidden under Jewish law.
Beyond food, "trefah" can sometimes be used metaphorically to refer to something that is morally or spiritually forbidden or undesirable.
It's important to note that the concept of "trefah" is rooted in Jewish religious and cultural traditions and doesn't have a universal meaning outside of that context.
