The core rules of kashrut (dietary laws) are:
* Land animals must have split hooves and chew their cud.
* Fish have to have scales and fins.
* Birds cannot be amongst those listed as forbidden in the Torah and cannot be hunters/scavengers
* Animals must be killed in a specific manner and must be free of all disease
* As much blood as possible must be removed from meat as consumption of blood is forbidden
* Dairy and meat cannot be combined in the same meal and there's a waiting period between eating one then the other.
* Orthodox Jews and some Conservative Jews will not eat certain fruits and vegetables because it's too difficult to guarantee that all bugs have been washed away (cauliflower, asparagus, and the like).
Additionally, food must be prepared and handled following kashrut. Any food that does not meet these requirements cannot be eaten by those who are religiously observant.
Yes. Torah-observant Jews will make sure that the ingredients are kosher.
When it comes to meats, Kosher is not synonymous with Halal, so no, we cannot eat Kosher Gelatin. Gelatin is considered kosher by many Jews regardless of its source of origin. For Muslims, if gelatin is prepared from swine or cows that are not dhabeeha, it is haraam.
Kosher is the diet of Jews. Jews keep kosher. If you keep kosher you cannot eat: shellfish, pork, or dairy mixed with meat. The main land of Jews is Israel. So technically, the nationality of kosher is Israel.
Yes, but Ashkenazi Jews are stricter than Sephardi Jews.
Meat or poultry should have Rabbinical kosher-certification. So, to answer the question, any meat or poultry that is kosher can be eaten by kosher observant Jews.
Anything that's kosher.
Jews are only able to eat kosher food because it is against their religion to eat non kosher food.
Religious Jews eat only kosher foods. Gluten is an ingredient in food.
Orthodox Jews keep a strictly kosher home.
Religiously observant Jews will only eat kosher food.
bagels and lox, and cholent - though not together! Correction: Although bagels and lox and cholent are specific items that Orthodox Jews might eat (assuming they're kosher), that would make for a rather boring and not too nutritious diet. Orthodox Jews can eat anything that is kosher.
Religiously observant Jews will not eat any food that is not kosher. The basis of kashrut is the Torah, this is a part of the guidelines for living righteously given to the Jews by HaShem.
