Key Takeaways
Cow’s milk, egg, peanut, tree nut, fish, shellfish, wheat, and soy are the eight major food allergies requiring careful management.
Strict avoidance of allergenic foods and reading food labels are crucial in preventing allergic reactions, with emergency medications like EpiPens essential for severe cases. The food industry plays a significant role in ensuring proper labeling and management of food allergies by following FDA regulations.
Patients and families should communicate allergies clearly and maintain awareness of cross-contamination risks when dining out or preparing food.
Milk Allergy
Cow’s milk allergy affects about 2-3% of infants in developed countries, but many outgrow it, with prevalence dropping below 1% by age six. Symptoms often appear within the first few months of life, including hives and difficulty breathing due to the immune system’s release of histamine.
Diagnosis relies on patient history and physical examination. The only effective treatment is strict avoidance of cow’s milk and related products. Breastfeeding reduces the incidence of cow’s milk allergy compared to formula feeding, and up to 90% of affected children may develop tolerance by age six. However, they are at increased risk of other food allergies.
Families need to be diligent about reading food labels and communicating with caregivers and schools to ensure their child’s safety. With careful management, children can safely navigate their world, even if they have to avoid cow’s milk.

Egg Allergy
Egg allergies, particularly to proteins found in egg whites, can cause skin reactions, respiratory issues, and gastrointestinal problems. About 70% of children with an egg allergy outgrow it by age 16.
Managing an egg allergy means avoiding whole eggs and any food products containing egg derivatives. Eggs are a common ingredient in many foods, but with careful planning and the right information about major food allergens, families can successfully navigate these dietary restrictions.
Peanut Allergy
Peanut allergies have risen significantly in the past two decades, now affecting 1-2% of US children. This food allergy is known for causing severe allergic reactions, including anaphylaxis, which can occur within minutes of exposure. Cross-contamination with tree nuts is also a concern.
Managing peanut allergies involves strict avoidance of peanuts and carrying emergency medications like an EpiPen. Oral immunotherapy has emerged as a promising treatment, aiming to increase tolerance in affected individuals. While peanuts are legumes, 25-40% of those allergic to peanuts may also react to tree nuts.
It is important to distinguish between wheat allergies and celiac disease, an autoimmune disorder triggered by proteins found in gluten-containing grains. Celiac disease can cause serious health issues, including intestinal damage and risks such as malnutrition and other autoimmune diseases, making gluten-free labeling crucial for consumer safety.
Living with a peanut allergy requires constant vigilance, but with proper education, emergency medications, and awareness of cross-contamination risks, individuals can manage their condition effectively.
Tree Nut Allergy
Tree nut allergies affect about 0.4-0.5% of the U.S. population and can be severe.
Fewer than 10% of individuals outgrow tree nut allergies.
Symptoms include:
abdominal pain
nausea
itching
difficulty swallowing
Peanut allergies often coexist with tree nut allergies, affecting about 40% of those with peanut allergies. Due to the risk of severe reactions like anaphylaxis, strict avoidance of all tree nuts is recommended. Be cautious with foods, cosmetics, and other products that might contain tree nut derivatives.
Fish Allergy
Fish allergies affect about 1% of Americans and are often undiagnosed until adulthood. This type of allergy typically refers to finned fish, not shellfish. Symptoms range from mild reactions to severe, life-threatening anaphylaxis.
Management involves avoiding the allergenic fish and being cautious with processed foods that might contain fish. Ensure that dining establishments are aware of the allergy to prevent cross-contact.
Shellfish Allergy
About 2% of Americans have a shellfish allergy. This allergy includes crustacean shellfish like shrimp, lobster, and crab, but individuals can often safely consume mollusks. Symptoms vary widely, from mild itching to severe anaphylaxis.
Managing a shellfish allergy involves strict avoidance and carrying emergency medications like an EpiPen. Communicate with restaurants about the allergy to ensure safe dining experiences.
Wheat Allergy
Wheat allergy is more common in children, with a prevalence of around 0.4%, and many outgrow it by age 12. Symptoms of wheat allergy include skin reactions, gastrointestinal distress, and respiratory issues. Children with wheat allergies often experience moderate-to-severe atopic dermatitis.
Wheat-dependent exercise-induced anaphylaxis occurs when physical activity follows wheat consumption. Diagnosis often involves skin prick tests and specific IgE assays, though these can be less reliable due to variability in protein content. Double-blind placebo-controlled food challenges are the gold standard for diagnosis.
Managing wheat allergy involves strict avoidance and careful reading of food labels to prevent accidental exposure. Knowing which wheat proteins cause reactions can help manage the allergy more effectively.
Soy Allergy
Soy allergy symptoms include gastrointestinal issues, respiratory problems, and skin reactions. Most children outgrow soy allergies. Managing this allergy involves avoiding soy and soy-based products, though highly refined soybean oil and soy lecithin are often tolerated.
Parents should be careful with dairy-free products, which might use soy as an alternative. Consult an allergist for personalized advice.
Food Labels and Allergens
Food labels are essential for managing food allergies. The FDA mandates that food manufacturers list major allergens clearly on packaged foods to safeguard consumers. The Food Allergen Labeling and Consumer Protection Act requires that major allergens be labeled by their common names.
Specific labeling requirements for certain foods enhance consumer awareness. Advisory statements like “may contain” or “produced in a facility that also uses” inform consumers about potential cross-contact.
Product recalls can occur when labeling issues are detected. For allergic consumers, these labels are essential for making informed choices.
Managing Food Allergies Safely
Reading food labels every time you shop is crucial, as manufacturers may change ingredients frequently. Prevent cross-contamination in the kitchen by using dedicated utensils for preparing food for allergic individuals. Always carry emergency medication, such as an EpiPen, if you have food allergies to ensure food allergy safety.
Create a written action plan for handling accidental exposure to allergens. Wear a medical ID bracelet to inform others in an emergency. Inform restaurant staff about specific food allergies when dining out for safety.
Recognizing and Responding to Allergic Reactions
Symptoms of severe allergic reactions, such as shellfish or soy allergies, range from mild itching to life-threatening allergic reaction anaphylaxis. Common symptoms of anaphylaxis include a weak pulse, difficulty breathing, and confusion.
Immediate action is essential, including calling emergency services and administering epinephrine if available. Keep an epinephrine autoinjector accessible and ensure those around you know how to use it properly.
Reporting Adverse Reactions
Consumers, patients, manufacturers, and health professionals can report adverse reactions or labeling concerns. Reports submitted to the FDA should be thorough, including as much information as possible.
Individuals can report adverse events using MedWatch Online reporting forms.
