My question is one about food.

All my aunts and uncles were/are Roman Catholic and they always ate fish on Fridays which (I think) symbolized Jesus when he feed a city on 1 fish and 1 loaf of bread.

PCB: Muslims don't eat pork do they??? Why??? What does a pig symbolize??

My best friend is Jewish and she does tries to keep kosher and she does not eat pork either.

For other religions, are there any food restrictions??
