Allergy - Food (Non-Vegetarian Only)

Yes. People can be allergic to non-vegetarian foods such as shellfish, fish, eggs and red meat. Reactions range from hives, swelling and gastrointestinal symptoms to respiratory problems and life‑threatening anaphylaxis. A unique red‑meat allergy (alpha‑gal) can be triggered by tick bites and causes delayed reactions. Diagnosis uses history, skin or blood IgE tests and supervised food challenges; treatment is avoidance and carrying epinephrine for severe allergies.

Ten common food allergies include milk, eggs, peanuts, tree nuts (e.g., walnuts, almonds), soy, wheat, fish, shellfish (crustaceans like shrimp and crab), sesame, and mustard. These often cause reactions ranging from mild hives and gastrointestinal symptoms to severe anaphylaxis; avoidance and prompt medical care for reactions are essential. Diagnosis is by clinical history, allergy testing, or supervised food challenge.

About 90% of food allergic reactions are caused by eight foods: cow’s milk, eggs, peanuts, tree nuts (e.g., almonds, walnuts), soy, wheat, fish, and shellfish (crustaceans and mollusks). These common allergens can cause reactions from mild hives to severe anaphylaxis, so people with allergies should read labels carefully and consult healthcare professionals for testing and management.

These must be declared on food labels in many countries to protect people with allergies. The 14 allergens are: cereals containing gluten (wheat, rye, barley, oats, spelt, kamut), crustaceans, eggs, fish, peanuts, soybeans, milk (including lactose), tree nuts (almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, pistachios, macadamia), celery, mustard, sesame seeds, sulphur dioxide/sulphites, lupin and molluscs.

Mutton can cause allergic reactions in susceptible people. Reactions may stem from meat proteins or the alpha‑gal carbohydrate (tick‑related red‑meat allergy), leading to hives, itching, gastrointestinal symptoms, wheeze, or rarely anaphylaxis. Cooking may reduce but not eliminate risk. If you suspect a meat allergy, avoid mutton and see a doctor or allergist for testing and an emergency plan (antihistamines or epinephrine).

Common food allergies include milk, eggs, peanuts, almonds, walnuts, cashews, pistachios, pecans, hazelnuts, Brazil nuts, fish (e.g., cod), shellfish/crustaceans (shrimp, crab), soy, wheat, sesame, mustard, celery, lupin, kiwi and apple. Reactions range from mild oral allergy symptoms to life‑threatening anaphylaxis; prevalence and triggers vary by age, geography and individual sensitivity.
