Kashrut is a set of rules that Jewish people follow when it comes to the food they eat. It's kind of like a guidebook that tells them which foods are okay to eat and which ones are not.
One of the main rules of kashrut is that certain animals are not allowed to be eaten, like pigs, camels, and rabbits. Other animals, like cows and chickens, are okay to eat but only if they are killed and prepared in a special way.
Another rule is that meat and dairy products cannot be eaten together. This means that if you have a cheeseburger, you are breaking the rule. Jewish people are also not allowed to eat certain parts of an animal, like its blood.
In addition to these rules, there are also guidelines for how the food is prepared and cooked. For example, utensils used for meat and dairy products must be kept separate and cleaned differently.
Overall, kashrut helps Jewish people make mindful and intentional choices about the food they eat and how it is prepared.
