Treif

Treif is a word that's used in the Jewish religion and refers to food that's not allowed to be eaten. It's kind of like when your parents tell you not to eat too much candy because it's bad for you, except in this case, it's not just about being unhealthy - it's a religious rule.

For example, in Jewish tradition, animals like pigs, shellfish and rabbits are considered treif, meaning they can't be eaten. This is because they're considered unclean or impure in some way. So when somebody says that a food is "treif," they mean that it's not allowed to be eaten by Jewish people.

There are other restrictions too, like not eating meat and dairy together, or making sure the animal was killed in a specific way. Some Jewish people follow these rules very closely, and others are more flexible. But no matter what, treif is a word that reminds people of the importance of following these religious dietary laws.
