The dietary laws governing the food consumption of the Jewish and Muslim communities are somewhat similar but also contain many distinctive differences. Though both Jewish and Muslim communities have comparable food restrictions, the variations that exist between them make both unique and culturally identifiable. In discussing and comparing Jewish and Muslim food consumption laws, though, it’s not only a matter of questioning the rules, the regulations, and the differences that exist, but also examining the causes for their existence. So, the question is not only “what did they eat” but “why could they or could they not eat it,” as well.

The Book of Leviticus enumerates a good many regulations on what can and can’t be eaten in the Jewish tradition. Food that adheres to Jewish dietary law is known as kosher. The most important rules concerning kosher food involve animals, sea creatures, and blood. Animals must be unblemished, not castrated, have cloven hooves, and “chew their cud.” When slaughtering and eating the animals that are allowed by law, no blood can be consumed. Fish are allowed as long as they swim in the ocean with fins and have scales. Shellfish and eels, for example, are not allowed. Fowl is allowed, though birds of prey and carrion eaters are not. There is a ban on animals that are carnivorous or omnivorous. Because the meat of a kid cannot be boiled in the milk of its mother, there’s a general restriction on eating meat and dairy in the same meal. Vegetables are considered kosher unless they are prepared in a way that violates kosher law. Though not technically kosher, wine is allowed as long as it is prepared by a Jew and adheres to their preparation restrictions.

Similar to Jewish kosher is Muslim halal. Many of the laws restricting Muslim food consumption are comparable to Jewish law. This is why a Muslim may seek out kosher foods if their own foods are unavailable. Like the Jews, Muslims cannot eat pork or any animal that is carnivorous or omnivorous, castrated animals, blemished animals, or meat that is sacrificed to anyone but God. They have no meat laws beyond that, so they are not restricted to only cloven hoofed and cud chewing animals. Just like Jewish dietary custom, the Muslim community also has a taboo on consuming blood. Meat must be properly slaughtered for it to be acceptable for consumption. Like the Jews, too, Muslim custom only allows for the consumption of fish that possess scales, but fins are not a requirement. The consumption of alcohol is prohibited. The Muslim diet is comparably less restricted than the Jewish diet, but there are rules in the Muslim dietary custom that are more strongly enforced such as the prohibition on alcohol and the eating of any insects because some insects are allowed in kosher law.

The creation of dietary customs is largely the result of the need to create a distinct cultural identity. Through food customs, a group can create a cultural self that is unique and separate or identifiable to that one specific group. The Jews, having always been a people dominated by other groups and later dispersed after the destruction of their temple, had a great need to place a division between them and other cultural groups. This resulted in a series of strict and specific dietary laws; their food consumption was one of the ways in which they identified their culture among many others. Muslim dietary customs are a mixture of Jewish customs and local food norms. Since the Muslim religion extends from the same basic religious tradition as Judaism, there are many features that are similar between the two, food customs included. It was only natural for the Muslim religion to adopt food customs with some of the other practices it absorbed from Judaism. Muslims did have the advantage of political and cultural dominance that the Jews did not. As a result, their sense of self and identity was strong and their need to set a separate identity less important. Due to this, they created dietary laws that were less restrictive. This is why they developed such a rich court cuisine-- they had a court, first off, which the Jews did not, and laws that did not too severely restrict what could and could not be eaten. These less severe laws were also the reason why they were able to adopt so many local food norms into their cuisine.

However, the need to establish a cultural identity isn’t the only answer to the “why” question. Religious ideas and values also played a role in the development of dietary customs. The Jewish religion places a lot of importance on strict categorization. God separated things into distinct groups like good and evil or light and dark. There is no in between area, no hybrid spaces. This is the reason Jewish dietary customs stress things that are in their most “pure” form since that is the form in which they are the closest to how God intended them to be. As a result, Jews are restricted from eating animals that straddle two categories, that are hybrids, blemished, and mixing certain foods together before eating. Leavened bread is also something restricted because the yeast puts the grain in a form that is different from how God made it. The blood taboo is also best explained in terms of religious value. Since blood is the fluid of life, it’s reserved for only God. Muslims adhere to many Jewish customs, adopting them and modifying them into a generally less restrictive standard. The Koran also ensures that Allah is merciful to anyone who is forced to violate these laws, which by nature creates a more relaxed standard.
