This includes the type of animals permitted for consumption, methods of slaughter, and the avoidance of certain food combinations. This diet goes beyond religious significance; it reflects a profound connection between faith and daily life. The kosher diet is a unique and meaningful dietary practice that helps foster a sense of community, mindfulness, and respect for the environment.

What Does Kosher Mean?

The word ‘kosher’ comes from the Hebrew term ‘kashrut’, which means ‘fit’ or ‘proper’. In simple terms, it means food that meets the standards set by Jewish dietary laws (1). It indicates which foods are allowed for consumption and how they must be prepared.

These rules come from religious texts like the Leviticus and Deuteronomy in the Torah. However, their practical applications and details are elucidated in the oral law. It was subsequently codified in the Mishnah (a foundational Jewish text containing oral laws) and Talmud (a comprehensive commentary and interpretation of the Mishnah that contains additional discussions and teachings) and further expanded upon in rabbinical literature.

protip_icon Trivia
Although the Torah does not explicitly state the rationale for many kashrut laws, some see them as tests of obedience, while others cite philosophical, practical, and hygienic reasons.

The Torah outlines which animals are considered clean (fit for consumption), such as cows and chickens, and which are unclean, such as pigs and shellfish. Rules about how food should be prepared and served include what should and should not be mixed. For example, dairy and meat are not to be mixed. It also offers guidance on humane methods of slaughter (shechita) (1).

Keeping kosher is not just about food; it is a way for the Jewish people to connect with their faith, heritage, and community. In modern times, various rabbinical organizations have emerged to certify products, manufacturers, and restaurants as kosher, often using a symbol called a hechsher to signify their endorsement.

While some strictly follow these rules, others may have a more relaxed approach. The findings from the Pew Research Center’s survey conducted between November 2019 and June 2020 involving 4,718 respondents in the U.S. revealed that only 17% of American Jews maintain kosher dietary practices within their households.

This percentage comprises 22% of Jews who identify with a religious affiliation and a mere 3% of Jews who do not associate with any specific religion. Notably, a substantial 95% of Orthodox Jews adhere to kosher practices in their homes. The figures stand at 24% for Conservative Jews and 5% for Reform Jews in this regard.

One can maintain the integrity of kosher traditions and dietary practices by keeping some key rules in mind. The following guidelines define what foods are considered clean and proper, as well as the methods and practices that ensure compliance with these sacred dietary laws.

Kosher Rules

Kashrut, the intricate world of Jewish dietary laws, is governed by a set of fundamental principles and guidelines that shape what can and cannot be consumed within this tradition.

1. Prohibited Animals

Certain animals are entirely off-limits, including their flesh, organs, eggs, and milk. However, this restriction specifically relates to consumption. The prohibited animals can otherwise be used in sports equipment or clothing, such as pigskin (2).

2. Humane Slaughter

The method of slaughter must adhere to Jewish law when it comes to animals that are permitted for consumption. This humane process, known as shechita, is a cornerstone of kashrut standards (3).

3. Blood Removal

Before meat and poultry can be considered kosher, all blood must be thoroughly drained or broiled out, leaving no trace behind (3).

protip_icon Trivia
Meat must undergo a process called ‘koshering’ before it can be considered kosher. This involves salting and rinsing it to remove residual blood. A special salt called kosher salt is used for this process.

4. Prohibited Parts

Even within permissible animals, certain parts (chelev and gid hanasheh) are restricted from consumption. Chelev refers to specific types of fat typically located around the internal organs of the animal, such as the kidneys and stomach. In the Torah (Leviticus 7:22-27), it is explicitly forbidden to eat chelev as it is considered sacred and set aside for God.

Gid hanasheh pertains to the sciatic nerve of the animal. The prohibition against consuming gid hanasheh originates from the biblical story in Genesis 32:25-33. Jacob, one of the patriarchs, wrestled with an angel who, during the struggle, touched the hollow of Jacob’s thigh and damaged the sciatic nerve. As a result, the Torah prohibits the consumption of this nerve to commemorate this event.

5. Bug Inspection

While fruits and vegetables are generally allowed, they must undergo rigorous inspection to remove any insects, which are not fit for consumption.

6. Meat And Dairy Separation

Kashrut imposes strict separation between meat and dairy products. Fish, eggs, fruits, vegetables, and grains can be enjoyed with either meat or dairy, but not both. However, some interpretations may restrict the consumption of fish with meat as well (2).

7. Utensil Separation

Utensils, including cookware and cooking surfaces, that have been in contact with meat must not be used with dairy (and vice versa). This separation extends to utensils that have been in contact with non-kosher food too, but only if the contact occurs when the food is hot.

8. Non-Jewish Grape Products

Grape products made by non-Jewish individuals are not considered kosher and are strictly prohibited.

While these principles represent the core of kashrut rules, additional rules and variations may apply based on specific circumstances and interpretations within the diverse and vast Jewish community.

Observing these kosher rules emphasizes cleanliness, proper food handling, and inspection. Thus, this practice offers many advantages beyond the preservation of cultural identity. Keep reading to discover the benefits of following the kosher diet.

Benefits Of The Kosher Diet

The kosher diet, rooted in centuries of tradition, offers several unique advantages:

1. Promotes Food Safety And Hygiene

The kosher diet often leads to better food quality standards. This is because it necessitates careful inspection and preparation of food. This results in the availability of fresher, healthier options to those who follow it.

Also, the particular rules of kashrut play a significant role in promoting food safety. For instance, they ensure that meat undergoes proper preparation and a thorough removal of blood. This meticulousness significantly reduces the risk of foodborne illnesses (4). Thus, individuals can have greater confidence in the safety and quality of their meals by adhering to these rules.

2. Propagates Humane Slaughter Practices

One of the key aspects of kashrut is the requirement for humane animal slaughter. This means that animals must be treated with respect and taken through a swift and painless slaughter process. This ethical treatment aligns with many people’s values and demonstrates a commitment to compassion for animals (3).

3. Encourages Mindful Eating

Keeping kosher necessitates careful consideration of every food item. Individuals must pay close attention to the ingredients, preparation methods, and the different food combinations. This level of mindfulness in eating promotes a greater awareness of dietary choices and their impact on one’s health (5).

This mindfulness extends beyond the physical aspects of food for many who follow the kosher diet. It becomes a spiritual practice and enhances their connection with their faith and heritage.

It guides them in selecting specific foods to eat, such as kosher-certified meats and fish with fins and scales. This reinforces their commitment to their tradition. In the following section, we shed further light on the foods you can have on the kosher diet.

Foods To Eat On The Kosher Diet

The following foods are allowed on the kosher diet:

1. Meat (Fleishig)

Kosher meat comes from animals that meet specific criteria outlined in the Jewish dietary laws. Some common options include beef, lamb, and poultry, provided they have undergone kosher slaughter and processing (3).

2. Dairy (Milchig)

Dairy products like milk, cheese, and yogurt are allowed, provided they are produced using kosher-certified ingredients and equipment. They should not be consumed together with meat in the same meal (2).

3. Pareve (Parve)

Pareve foods are neither dairy nor meat. These include fish, eggs, fruits, vegetables, grains, and many other non-animal products.

Fish is not classified as meat due to historical interpretations of biblical texts. Fish do not produce milk and have different characteristics from land animals. Thus, they can be consumed with both dairy and meat.

4. Plant-Based Foods

Plant-based foods like fruits, vegetables, legumes, nuts, and grains are staples of the kosher diet. These are naturally kosher and form the foundation of many kosher meals.

5. Kosher Fish

Certain species of fish with fins and scales are considered kosher. These include salmon, tuna, and cod.

6. Kosher-Certified Snacks

Many packaged snacks, candies, and baked goods are available with kosher certification.

7. Kosher Wine And Grape Juice

Wine and grape juice produced according to kosher standards can be enjoyed.
