What Foods Do Judaism Not Eat

Judaism is a religion that encompasses various beliefs and practices, many of which revolve around dietary restrictions. Food affects us in a powerful way, and one of the fundamental aspects of Judaism is the practice of maintaining a healthy and wholesome lifestyle. In doing so, there are certain foods that are prohibited in Jewish dietary law. Some of these restrictions are simply related to tradition, while some are based on health benefits.

The most well-known prohibition in Jewish dietary law is the restriction of pork and its derivatives. Many ancient civilizations regarded pork and its derivatives as unclean, and it is believed that the restriction of pork in Judaism came from an association with ancient idols. Additionally, this prohibition is attributed to the lack of healthy qualities found in the animal. Pork can potentially contain harmful bacteria and parasites, and the lack of refractory period associated with pork makes it particularly susceptible to carrying these harmful agents. The Torah also prohibits the consumption of blood, blood sausage, and anything made with the blood of an animal, such as jelly.

Another prohibition in Jewish dietary law is the combination of certain foods. It is believed that eating certain foods together can have a negative effect on health, as certain foods do not metabolize properly in the presence of others. Dairy and meat are not allowed to be combined due to their different digestive times, and large amounts of fat are considered unclean and unhealthy.

This restriction is based on both health benefits and traditional unacceptability. In the modern era, health benefits have been more closely linked with dietary law, as science has started to understand how different foods can interact with our bodies in a positive or negative way. While the restrictions may seem strange to those unfamiliar with Jewish customs, it is important to recognize why they are there and the potential benefits of following them.

The last important restriction in Jewish dietary law is the practice of ritual slaughter. Animals must be slaughtered in a certain way that is both humane and respectful to the animal’s life. It is a complicated process, and this restriction is attributed to the idea that animals should not suffer needlessly. This practice is seen as an active participation in the notion of Ahimsa, or “non-violence”, which is at the core of many teachings of Judaism.


Insects are not allowed to be eaten in Judaism, as they are viewed as unclean and unclean animals. This prohibition comes from both traditional and religious sources. It is seen as a sign of respect for the environment, as well as for the animal itself. Insects play an important role in the environment, and their consumption can potentially be dangerous. Additionally, certain insects may also have religious kashrut (Jewish dietary) issues, as some types of insects are not kosher.


Seafood is allowed in Judaism, but there is an important caveat to this rule. Some species of fish, such as eels, are not allowed to be eaten due to their scavenging habits and lack of fins. Additionally, shellfish, such as lobster and crab, is not allowed due to their lack of scales and the potential risks of consuming them. As with other dietary laws, this restriction is based on health and traditional reasons.

Fish With Non-Kosher Scales

Some fish, such as catfish, sturgeon, and lamprey, are not allowed to be consumed due to their lack of kosher scales. The lack of scales makes the fish difficult to distinguish from non-kosher species, which is why these fish are not allowed to be consumed. Additionally, there are certain species of fish that are not allowed to be consumed as they are simply too bony or difficult to clean. This is a precaution to avoid potential health hazards.

Farming Animals

Animals that are farmed and raised for their meat, such as cows, pigs, and sheep, are not allowed to be consumed in Judaism due to their associated risk of carrying various diseases. This prohibition comes from a combination of both health reasons and religious beliefs. Additionally, there are certain animal parts that are forbidden, such as the sciatic nerve, which is located in the hind leg of a cow. This nerve is forbidden to be consumed due to both health and religious reasons.

Kosher and Non-Kosher Food

The concept of kosher and non-kosher food is a complex one, as the laws governing what is allowed and not allowed to be consumed can sometimes be confusing. The primary rule of thumb is to follow the Torah and the guidance of a rabbi or other religious leader when considering the kashrut (Jewish dietary law) of a certain food item. Some common signs that a food item is not kosher are the presence of dairy, pork derivatives, unclean species and parts of animals, and the combination of meat and dairy. Additionally, any food item that has been processed by non-kosher methods, such as deep-frying, is not allowed to be consumed.

Complying With Jewish Dietary Law

When it comes to following the restrictions of the Torah, it can be difficult to keep up with the specific rules associated with each dietary law. It is important to consider the potential risks and benefits associated with following certain dietary restrictions. Additionally, one should consult a rabbi or trusted religious leader for confirmation on what is and what is not allowed. This will help to ensure that one is in full compliance with Jewish dietary law.

Health Benefits of Following Jewish Dietary Law

The restrictions of Jewish dietary law can have many positive health benefits. For example, the prohibition of certain animal products such as pork and its derivatives can reduce the risk of ingesting harmful bacteria or parasites. Additionally, avoiding dairy and meat combinations can reduce the risk of digestion issues. The practice of ritual slaughter also ensures that animals are slaughtered in a humane and respectful way, and this can reduce the risk of potential health hazards associated with consuming leaner animals. Lastly, avoiding non-kosher food items such as non-kosher processed food can help to ensure one’s overall well-being.

Impact on Society

In addition to the health benefits associated with following Jewish dietary law, the practice of dietary restrictions can also have a positive impact on society. For example, the practice of ritual slaughter helps to ensure that animals are treated with respect and not subjected to cruelty. Additionally, avoiding certain foods can also help to reduce one’s carbon footprint. By avoiding certain animal products, one can help to reduce the demand for factory-farmed animals, which can help to reduce the pollution associated with the process. Following Jewish dietary law can also be a way to show solidarity with the Jewish community.

How To Implement Jewish Dietary Law

Fortunately, there are a variety of resources available to help one to understand and implement Jewish dietary law. Many local Jewish communities have religious classes and events aimed at teaching about Jewish dietary law and its importance. Additionally, it is important to consult scholars and religious leaders when considering specific dietary restrictions. Educating oneself about the specific restrictions is an important step in learning how to properly follow the law.


Ultimately, there are various dietary restrictions in Judaism that help to ensure a healthier and more wholesome lifestyle. Knowing what foods are allowed and which are prohibited can help to ensure one’s overall well-being and practice of the religion in a respectful manner. Additionally, understanding the potential health benefits, environmental considerations, and the impact on society can help to give one a greater appreciation of Jewish dietary law.
