halal or kosher food
Yes, tuna is a kosher fish. Canned tuna must be kosher certified though.
Yes, but Ashkenazi Jews are stricter than Sephardi Jews.
Only if it's kosher.
Sharks, rays, eels, and catfish are all good examples of fish (in the traditional sense) that are non-kosher.
Orthodox Jews are only allowed to eat kosher foods.
Yes. The ingredients should be kosher.
Jews who keep kosher do not eat prawn, since it's not a kosher species of sea creature.
No, this is not allowed for those who keep kosher.
If the food is Kosher, it is not forbidden. That said, you can't mix Kosher milk with Kosher meat, as the mixing of meat and dairy is not allowed. Certain parts of Kosher animals may not be eaten either. Blood, the fat which surrounds the vital organs, and the sciatic nerve and its adjoining blood vessels may not be eaten.
According to the Torah, it is technically allowed. But thousands of years ago the Rabbis made a decree that chicken is considered like meat in all aspects. Therefore, you are not allowed to cook chicken and cheese together. If you do cook them together, it is not kosher and Jews are not allowed to eat it.
There are so many different things that KOSHER Jews are not allowed to eat. Shellfish is not allowed, so that means shripmp and scallops are not allowed.
