Does gluten-free mean kosher?

Quick Answer

Gluten-free does not necessarily mean kosher. For a food to be certified kosher, it must comply with Jewish dietary laws, which include restrictions on ingredients, preparation methods, and handling. While many kosher foods are gluten-free, some gluten-free foods may not be kosher.

What is Gluten?

Gluten is a protein found in grains like wheat, barley, and rye. It gives elasticity to dough and helps baked goods keep their shape. For people with celiac disease or non-celiac gluten sensitivity, consuming gluten triggers an autoimmune response that damages the small intestine. That’s why they follow a strict gluten-free diet.

What Does Gluten-Free Mean?

A food labeled “gluten-free” must contain less than 20 parts per million of gluten. This trace amount is generally considered safe for most people who are sensitive to gluten. True gluten-free foods are made without wheat, barley, rye or any derivatives of those grains. Common substitutions include rice, quinoa, corn, and oats.

What Does Kosher Mean?

Kosher refers to foods that comply with Jewish dietary regulations. These laws are based on biblical passages and rabbinic teachings. Kosher guidelines apply not just to ingredients, but to food production, processing, and handling as well. Only specially trained rabbis can certify that a product is kosher.

Kosher Dietary Restrictions

Here are some key kosher dietary restrictions:

Allowed Animals

Kosher land animals must have cloven hooves and chew their cud, like cows, sheep, and goats. Kosher birds include chicken, turkey, duck, and goose. Only fish with fins and scales are permitted, so shellfish like lobster, shrimp, crab, and clams are forbidden.

Meat and Dairy

Dairy products cannot be consumed with meat or meat-derived foods. Kosher kitchens use separate dishes, utensils, and appliances for meat and dairy. After eating meat, observant Jews wait 3-6 hours before consuming dairy.


Consuming blood is prohibited. Kosher meat undergoes a special salting process to remove residual blood.


All kosher animal products must come from healthy animals that are slaughtered quickly and humanely by a trained kosher slaughterer (shochet). The lungs are checked for flaws to verify health.

Mixing Meat and Dairy

It is forbidden to cook, serve, or eat dairy and meat products together. This law comes from the biblical passage, “You shall not boil a kid in its mother’s milk.” Keeping milk and meat separate reinforces the kosher prohibition on consuming blood.


Any ingredient used in a kosher product must itself be kosher. This includes oils, flavorings, coloring, stabilizers, and vitamins. Wine and grape products must be certified kosher as well.


The equipment used to produce kosher foods cannot have been used for non-kosher foods. Shared equipment must undergo kosherization, a thorough cleaning process.

Why Go Gluten-Free If You’re Not Sensitive?

Those without celiac disease or non-celiac gluten sensitivity do not need to follow a gluten-free diet for medical reasons. However, some people go gluten-free because they believe it has health benefits like:

– Losing weight. Some find it easier to lose weight on a gluten-free diet.

– Reducing inflammation. For those with chronic inflammation, avoiding gluten may help reduce it.

– Improving energy. Those with fatigue report having more energy without gluten.

– Easing digestive issues. Cutting out gluten relieves symptoms for some people with IBS or other GI problems.

– Clearing “brain fog.” Gluten is linked to inflammation that may affect cognition, so going gluten-free could sharpen mental clarity.

However, research has not conclusively proven these benefits in non-celiac populations. Consult a doctor before starting a gluten-free diet if you do not have celiac disease or gluten sensitivity.

Can Gluten-Free Foods Be Kosher?

Yes, gluten-free foods can absolutely be kosher, provided they meet all other kosher laws regarding ingredients, preparation, and handling. In fact, most naturally gluten-free whole foods like fruits, vegetables, eggs, meat, fish, nuts, seeds, and unprocessed dairy are kosher.

Many processed gluten-free products can be certified kosher if they use kosher ingredients and are not contaminated with non-kosher elements. There are certification agencies that oversee kosher compliance for packaged foods.

So while gluten-free does not inherently mean kosher, gluten-free foods are very often able to meet kosher standards.

Examples of Gluten-Free Kosher Foods

Here are some examples of foods that can be both gluten-free and kosher:

– Fruits and vegetables
– Eggs
– Meats like beef, lamb, chicken, and turkey
– Fish with fins and scales like salmon, tuna, cod, and trout
– Dairy products like milk, yogurt, and cheese
– Nuts and seeds
– Gluten-free grains like rice, corn, quinoa, amaranth, and buckwheat
– Gluten-free flours like rice flour, potato starch, tapioca flour, and nut flours
– Oats certified gluten-free
– Legumes like beans, lentils, and chickpeas
– Natural nut butters like peanut butter and almond butter
– Condiments like vinegars, oils, mustards, and spices
– Kosher certified gluten-free packaged foods like bread, pasta, cereal, crackers, etc.

As long as these foods meet kosher standards for ingredients and preparation, they can be enjoyed on a gluten-free kosher diet.

Can Kosher Foods Contain Gluten?

Yes, kosher foods may contain gluten. While many traditional Jewish foods are naturally gluten-free or use gluten-free grains, others are made with wheat, barley, or rye and therefore do contain gluten.

Examples of kosher foods that often contain gluten include:

– Bread products like challah, bagels, matzo
– Pasta
– Couscous
– Cereals
– Baked goods like cakes, cookies, muffins, and pies
– Beer and other fermented beverages
– Soy sauce, teriyaki sauce, salad dressings, and other condiments
– Processed meat products like hot dogs, lunch meat, gefilte fish, etc.
– Breading and coating mixes
– Packaged kosher meals
– Snack foods like pretzels, crackers, granola bars, etc.

So people who need to follow gluten-free diets for medical reasons cannot automatically eat anything that is labeled kosher. They still need to read labels and ingredient lists carefully to avoid gluten, even when choosing kosher products.

What Makes a Food Kosher Certified?

For a packaged food to bear a kosher certification symbol, it must meet the following criteria:

– All ingredients must be kosher. The supplier of each ingredient must provide documentation verifying kosher status.

– The processing facility and equipment must only be used for kosher production, or go through kosherization cleaning if shared.

– There must be no contact between meat and dairy during production. Separate production lines are ideal.

– Rabbinic inspectors supervise key points in production to ensure kosher standards are followed at all times.

– Random product samples undergo laboratory testing to detect any traces of non-kosher elements.

– Strict record keeping tracks each raw ingredient from its supplier through the completion of the finished product.

– The certification agency stands behind the kosher status of the product, staking its reputation on this endorsement.

Conscientious consumers who follow a kosher diet can look for kosher symbols from certification organizations like OU, OK, Star-K to ensure packaged foods truly meet all kosher criteria from start to finish.

Should You Follow a Gluten-Free Kosher Diet?

Here are some reasons you may consider combining gluten-free with kosher guidelines:

– You have celiac disease or non-celiac gluten sensitivity and want the assurance that kosher foods are strictly gluten-free.

– You want to exclude all potentially inflammatory foods including gluten. Following kosher rules reduces exposure tocertain additives.

– You have concerns about food quality and prefer to eat natural, minimally processed ingredients with clear origins – ideals aligned with kosher laws.

– You want to observe Jewish dietary laws but need to be gluten-free, so desire foods that accommodate both needs.

– You appreciate the extra level of care and inspection involved with kosher foods that results in high quality products.

– Following both gluten-free and kosher guidelines gives you peace of mind that you are nourishing your body in the healthiest way.

However, a gluten-free kosher diet does take effort. It requires diligent label reading, asking questions when dining out, sticking to specialized products, and avoiding most processed foods. Consider whether the rigor of this diet suits your needs and preferences. Consult a registered dietitian to help make this diet workable and lasting.

Tips for Following a Gluten-Free Kosher Diet

Here are some tips to make it easier to eat gluten-free kosher foods:

– Cook more meals at home using naturally gluten-free kosher ingredients like meat, poultry, fish, eggs, dairy, produce, nuts, seeds, and unprocessed starch.
– Choose certified kosher gluten-free packaged products like bread, pasta, cereal, crackers, pancake mix etc.
– When dining out, look for kosher certified menus and gluten-free options.
– For special occasions, order kosher certified gluten-free baked goods from bakeries that offer them.
– Research which mainstream brands offer gluten-free options certified kosher.
– Learn alternative cooking and baking methods to make classics gluten and kosher, like matzo balls made with potatoes instead of matzo.
– Find support from other gluten-free kosher eaters who can share tips, recipes, and product recommendations.
– Use kosher meal delivery services that cater to gluten-free needs.
– When in doubt about an ingredient or menu item, ask questions to determine if it meets both dietary needs.

Following a dual gluten-free kosher diet does limit your choices compared to one or the other. But with the rise in special dietary needs and food allergies, the selection of high quality gluten-free kosher foods is better than ever and still growing. With attention and planning, you can follow this diet in a rewarding, sustainable way.


While gluten-free does not automatically equal kosher, it is possible to accommodate both dietary lifestyles. Kosher laws go beyond just ingredients to encompass strict food production standards. Gluten-free eaters need to look for kosher certification symbols to verify adherence to these comprehensive criteria. With careful label reading and awareness when dining out, you can successfully combine gluten-free with kosher guidelines. Following this dual diet requires commitment but can be worthwhile for improving health.
