Food allergy and gluten FAQ

Gluten-Free & Celiac

Celiac disease is an autoimmune condition where gluten — the protein in wheat, barley, and rye — triggers immune damage to the lining of the small intestine. Non-celiac gluten sensitivity may cause digestive discomfort, fatigue, or other symptoms, but it does not produce the same intestinal damage or autoimmune response. If celiac disease is suspected, do not start a gluten-free diet before medical testing, because going gluten-free first can affect test accuracy.

Gluten-Free & Celiac

Not always. Standard oats are frequently processed or grown alongside wheat and can carry gluten through cross-contact. For celiac-safe cooking, choose oats that are specifically labeled gluten-free, which means they meet the FDA's gluten-free standard of less than 20 parts per million. Even with certified oats, some people with celiac disease may need to follow individual medical guidance about oat tolerance.

Gluten-Free & Celiac

Rice, corn, potatoes, quinoa, and buckwheat are naturally gluten-free and form the foundation of most gluten-free cooking. Millet, sorghum, teff, and amaranth are also gluten-free grains. With packaged products, always check for a gluten-free label, read the ingredient list, and look for cross-contact warnings — especially for celiac disease.

Gluten-Free & Celiac

Usually not. Wheat flour contains gluten, which gives dough its elastic structure and helps baked goods hold together. Most gluten-free baking works better with a blend of flours — such as rice flour or tapioca starch — plus a binder like xanthan gum or psyllium husk. Liquid ratios and resting time may also need adjustment. This is culinary guidance, not a medical safety guarantee.

Gluten-Free & Celiac

No. Gluten-free only addresses the gluten protein found in wheat, barley, and rye. A gluten-free recipe can still contain milk, eggs, tree nuts, peanuts, soy, sesame, or other allergens. Always check every ingredient label and allergy statement for each specific restriction in your household.

Nut Allergies

No. Peanuts are legumes — they grow underground and are botanically closer to lentils and chickpeas than to nuts. Tree nuts include almonds, walnuts, cashews, pistachios, pecans, and hazelnuts. A person may be allergic to peanuts only, tree nuts only, or both. Never substitute one for the other in an allergy-safe recipe without specific medical clearance.

Nut Allergies

Read the ingredient list carefully for nut names, their derivatives (almond flour, walnut oil, marzipan), and the allergen statement on the label. Phrases like "may contain nuts," "made in a facility with tree nuts," or "made on shared equipment" indicate possible cross-contact but are voluntary statements and not regulated to a specific risk level. Evaluate these warnings based on the severity of the allergy and personal medical guidance.

Nut Allergies

Sunflower seeds and pumpkin seeds work well as crunch replacements in cookies and bars. Sunflower seed butter can substitute for nut butters in most recipes, though it may turn baked goods green due to a natural reaction with baking soda — this is harmless. Oat flour or neutral seed flours can replace almond flour, though texture and fat content will differ. Always confirm no cross-contact warning on the package when preparing food for someone with a nut allergy.

Nut Allergies

Yes. Almond flour is made from a tree nut and is not suitable for someone avoiding tree nuts. Choose substitutes only after checking the relevant allergen and the package label.

Dairy-Free & Lactose Intolerance

Milk allergy is an immune response to milk proteins. Lactose intolerance is difficulty digesting the milk sugar lactose. A lactose-free product is not automatically safe for a person with milk allergy.

Cross-Contamination Prevention

Cross-contact happens when food without an allergen touches a tool, surface, or ingredient that had the allergen. In family kitchens, this is especially relevant for gluten, nuts, milk, soy, and sesame.

Cross-Contamination Prevention

For celiac-aware cooking, a separate toaster or a method that prevents contact with wheat crumbs is often safer. Regular cleaning may not remove crumbs from inside a toaster.

Cross-Contamination Prevention

Store risky ingredients separately, label containers, use clean spoons, and never return a spoon that touched another food back into a spread or flour container.

Cross-Contamination Prevention

Start with clean hands, clean tools, and a clean surface. Prepare the allergy-adapted dish first, then foods containing the allergen, to reduce cross-contact risk.

Gluten-Free & Celiac

The most important first step is removing all sources of gluten from your diet — wheat, barley, rye, and their derivatives. This means switching to naturally gluten-free grains (rice, potatoes, quinoa, corn) and checking every packaged food label for gluten-containing ingredients and cross-contact warnings. In your kitchen, prevent cross-contact by using dedicated gluten-free toasters, cutting boards, colanders, and storage containers. Work with a registered dietitian experienced in celiac disease for a personalized transition plan — the diet is lifelong.

Source: NIDDK, FDA

Gluten-Free & Celiac

Not necessarily. Many packaged gluten-free products compensate for the absence of wheat by adding more sugar, fat, or starch to improve texture, and they are often lower in fiber and B vitamins than their wheat-based equivalents. For people without celiac disease or gluten sensitivity, a gluten-free diet offers no proven health benefit and may reduce dietary variety. The recipes here are gluten-free because they support celiac disease and gluten sensitivity needs — not because gluten is inherently unhealthy.

Source: NIDDK

Gluten-Free & Celiac

Psyllium husk is the ground outer shell of psyllium seeds, used in gluten-free baking as a binder and structure builder. When mixed with water it forms a gel that mimics some of the elastic behavior of gluten — helping bread hold its shape, trap gas bubbles, and develop a better crumb. It is also a source of dietary fiber. Use it in the amount specified in the recipe; too much makes baked goods dense and gummy.

Nut Allergies

A nut allergy is an immune system reaction that can cause hives, swelling, difficulty breathing, or anaphylaxis — a life-threatening emergency. Even tiny amounts can trigger a reaction. A food intolerance involves digestive discomfort (gas, bloating, nausea) without an immune response and is generally not life-threatening. The management of a nut allergy requires strict avoidance and an emergency action plan (such as carrying an epinephrine auto-injector), while an intolerance may only require reducing portion size.

Source: FDA

Nut Allergies

Not automatically. Peanut allergy and tree nut allergy are separate conditions, and a person can have one, both, or neither. However, many people with peanut allergy also have tree nut allergy, and peanut-containing products are often processed alongside tree nuts. Consult an allergist for testing before introducing tree nuts to a child with a known peanut allergy. In allergy-safe cooking, treat the two categories separately unless medical testing has confirmed safety.

Source: FDA

Dairy-Free & Lactose Intolerance

Vegan cheese does not contain milk proteins and is safe for milk allergy in terms of dairy, but check the label carefully. Most vegan cheeses are made from cashews (tree nuts), almonds (tree nuts), or soy — which can be problematic if those are also restricted. Some brands use coconut oil and starch as a base and are free from the most common allergens, but cross-contact warnings on the package should still be checked.

Source: FDA, University of Illinois Extension

Dairy-Free & Lactose Intolerance

Usually not. Milk allergy is typically a reaction to casein and whey proteins, which are present in all mammalian milks including goat, sheep, and buffalo. Most people with cow's milk allergy will also react to goat and sheep milk. Plant-based milks — oat, rice, hemp, coconut — are the safest choice for those with a confirmed milk allergy. Always confirm with an allergist before introducing any alternative milk.

Egg-Free Cooking

Egg allergy is one of the most common food allergies in children, though many outgrow it by adolescence. The immune system reacts to proteins in egg whites (primarily ovalbumin) or yolks. Reactions can range from hives and digestive discomfort to anaphylaxis. Both egg whites and egg yolks can cause reactions, so full egg avoidance is typically required. Egg proteins also appear in many vaccines — consult an allergist about vaccination needs.

Source: FDA

Egg-Free Cooking

Eggs can appear under many names: albumin, globulin, lecithin (when from egg), livetin, lysozyme, mayonnaise, meringue, ovalbumin, ovomucin, ovomucoid, ovovitellin, silici albuminate, and surimi. Egg is a required allergen label in the US and EU, so the allergen statement will list it directly. Brush glazes, egg washes on pastry, and some pasta are common hidden sources. Many pasta varieties contain egg even if the name does not suggest it.

Source: FDA

Cross-Contamination Prevention

Start with a shared "safe zone" approach: designate shelf areas and containers for each person's safe foods. Use color-coded cutting boards and utensils (one color per allergy restriction). Cook the most restricted person's food first on a clean surface with clean tools. Keep shared condiment jars double-dip free by using clean spoons to scoop rather than dipping utensils that touched other food. Label everything clearly, and involve older children in understanding why the system matters.

Source: FDA

Cross-Contamination Prevention

For most allergens, a hot dishwasher cycle is effective at removing protein residues. However, for celiac disease, porous or scratched wooden utensils, wooden cutting boards, and items with deep crevices (like wooden spoons or graters) may retain gluten even after washing. These items are typically recommended to be replaced with dedicated gluten-free versions rather than shared and washed. For most smooth metal and glass surfaces, dishwasher washing is sufficient.

Food Labels Explained

The FASTER Act (Food Allergy Safety, Treatment, Education, and Research Act) designated sesame as the ninth major food allergen in the United States, effective January 1, 2023. This means all packaged food products sold in the US must now declare sesame clearly on their labels — either in the ingredient list or in a separate "Contains: sesame" statement. Before 2023, sesame was not required to be listed as a distinct allergen, meaning older recipes or products from before this date may not reflect the current labeling standard.

Source: FDA

Food Labels Explained

No. Wheat-free means a product contains no wheat, but it may still contain barley or rye — both of which contain gluten. For celiac disease or gluten sensitivity, "wheat-free" labeling is not sufficient; look specifically for a gluten-free declaration that covers all gluten sources. Conversely, a gluten-free product may still contain wheat starch if it has been processed to remove gluten below 20 ppm, so always check the full label.

Source: FDA, NIDDK

Pareve & Kosher Adaptations

No. Pareve means the product does not contain meat or milk ingredients under Jewish dietary law, but kosher certification does not address allergen cross-contact in the way medical allergy management requires. A pareve product may be produced on equipment shared with dairy, and the kosher standard for "dairy-free" is different from the medical threshold for milk allergy safety. People with milk allergy should always rely on the allergen statement and ingredient list — not pareve certification — for safety decisions.
