Jewish people do not eat pork. Its not bad for you any more than other hamburger and pork is from a pig so bacon and ham are both pork. I love bacon!!!! Before the new testament there were limits set on food.... no bottom feeders (crab) or hoved animal (pig) that is unclean.
Actually pork is one of the healthier meats you can eat next to chicken and turkey. Of course that is not including bacon which is quite bad for you. The main reason people wouldn't eat it would probably be for religious reasons.
