Food Allergy Treatment

What is Food Allergy?

A food allergy is an abnormal immune response to a specific food protein. When a person with a food allergy consumes even a tiny amount of the offending food, their immune system mistakenly identifies that food protein as harmful and launches an attack against it. This reaction involves the release of histamine and other chemicals, leading to symptoms that can range from mild discomfort to life-threatening anaphylaxis.

Food allergies affect millions of people worldwide, with increasing prevalence in both children and adults. They can develop at any age, though certain food allergies are more common in childhood and may be outgrown, while others persist throughout life. It is crucial to distinguish true food allergies from food intolerances, as the mechanisms, symptoms, and management differ significantly.

True food allergies involve the immune system and can be life-threatening. Food intolerances, such as lactose intolerance, involve the digestive system and are generally less dangerous, though they can cause significant discomfort.

Common Symptoms & How to Recognise Food Allergy

Food allergy symptoms typically appear within minutes to two hours after consuming the offending food. Symptoms can affect multiple organ systems:

Mild to Moderate Symptoms:

Skin Reactions (Most Common):

  • Hives (urticaria): Raised, itchy, red welts anywhere on the body
  • Angioedema: Swelling of lips, face, tongue, throat, or other body parts
  • Eczema flare-up: Itchy, red, dry patches
  • Generalised redness or flushing

Oral Symptoms: Itching or tingling in mouth, lips, or throat; swelling of lips, tongue, or palate

Gastrointestinal Symptoms: Nausea, vomiting, abdominal pain or cramping, diarrhoea

Respiratory Symptoms: Runny or stuffy nose, sneezing, coughing, mild wheezing

Severe, Life-Threatening Symptoms (Anaphylaxis):

Anaphylaxis is a medical emergency requiring immediate treatment with epinephrine. Symptoms include:

  • Airway and Breathing: Difficulty breathing or wheezing, throat tightness, hoarse voice, swelling of tongue or throat, repetitive cough
  • Circulation: Severe drop in blood pressure (shock), rapid weak pulse, dizziness, lightheadedness, fainting, pale clammy skin
  • Gastrointestinal: Severe vomiting or diarrhoea, abdominal cramping
  • Neurological: Confusion, anxiety, loss of consciousness
  • Skin: Widespread hives or redness, generalised itching

Common Food Allergens

While any food can potentially cause an allergic reaction, a small group of foods accounts for the majority of food allergies. The "Big Nine" Major Food Allergens:

  • Milk: Cow's milk is one of the most common childhood food allergies. Many children outgrow milk allergy by school age
  • Eggs: Egg allergy is common in children, particularly to egg whites. Many children outgrow egg allergy
  • Peanuts: One of the most common and potentially severe food allergies. Typically persists throughout life
  • Tree Nuts: Almonds, walnuts, cashews, pistachios, pecans, hazelnuts, Brazil nuts, macadamia nuts. Often lifelong
  • Soy: Common in young children; many outgrow soy allergy
  • Wheat: Wheat allergy differs from celiac disease. Many children outgrow wheat allergy
  • Fish: Salmon, tuna, cod, and other finned fish. Often develops later in life and tends to persist
  • Shellfish: Shrimp, crab, lobster, prawns, molluscs (clams, mussels, oysters). Common in adults, typically lifelong
  • Sesame: Increasingly recognised as a major allergen; can cause severe reactions

Other Notable Allergens: Fruits and vegetables (oral allergy syndrome), legumes (chickpeas, lentils, peas), seeds (mustard, sunflower, poppy, flax), spices (coriander, cumin, fenugreek)

How is Food Allergy Diagnosed?

Accurate diagnosis of food allergy is essential to avoid unnecessary dietary restrictions while ensuring safety. Evaluation typically includes:

  • Medical History Review: Detailed discussion about suspected food, timing of reaction, symptoms, amount consumed, and family history of allergies
  • Physical Examination: Assessment for signs of other allergic conditions
  • Skin Prick Testing: Food allergen extract placed on skin; positive reaction indicates possible allergy. Results within 20 minutes
  • Specific IgE Blood Tests: Measures IgE antibodies to specific foods
  • Component-Resolved Diagnostics: Advanced blood testing to distinguish mild vs. severe reaction likelihood
  • Oral Food Challenge (Gold Standard): Most accurate test. Performed under strict medical supervision with emergency equipment. Patient receives gradually increasing doses of suspected food
  • Elimination Diet: Removing suspected foods for 2-4 weeks, followed by reintroduction under medical supervision

Treatment Options Available

Currently, there is no cure for food allergy. Management focuses on avoidance and prompt treatment of reactions:

1. Strict Allergen Avoidance

  • Food Label Reading: Education on identifying allergens on ingredient labels, including hidden sources and cross-contamination risks
  • Cross-Contamination Prevention: Safe food preparation, avoiding shared utensils, cutting boards, and fryers
  • Dining Out Safely: Strategies for communicating allergies to restaurant staff
  • Travel Considerations: Planning safe meals, carrying safe snacks, translation cards for international travel

2. Emergency Action Plan

Every patient with food allergy should have a personalised written plan including: recognition of early symptoms, epinephrine auto-injector use instructions, when to use epinephrine, and emergency contact information.

3. Epinephrine Auto-Injectors

  • Prescription and comprehensive training on proper use
  • Carrying two doses at all times
  • Expiration date monitoring and replacements

4. Medications for Mild Reactions

Antihistamines for mild symptoms like localised hives or itching. Note: Antihistamines do NOT treat anaphylaxis and should never replace epinephrine when needed.

5. Oral Immunotherapy (OIT) – Emerging Treatment

Gradual introduction of increasing amounts of the allergenic food under medical supervision. Goal is protection against accidental exposures, not a cure. Currently available for peanut allergy, with research ongoing for milk, egg, and other foods. Requires commitment to daily dosing and regular follow-up.

6. Monitoring for Resolution

Many children outgrow allergies to milk, egg, soy, and wheat. Regular follow-up with repeat testing and oral food challenges may be recommended to confirm if an allergy has been outgrown.

Food Allergy vs. Food Intolerance

Feature Food Allergy Food Intolerance
Mechanism Immune system involvement Digestive system (enzyme deficiency, metabolic)
Onset Minutes to 2 hours Delayed (hours to days)
Symptoms Skin, respiratory, gastrointestinal, cardiovascular Primarily gastrointestinal (bloating, gas, diarrhoea, cramping)
Severity Can be life-threatening (anaphylaxis) Uncomfortable but not life-threatening
Amount Trigger Tiny amounts can trigger Often dose-related
Diagnosis Skin tests, IgE blood tests, oral challenges Elimination diets, breath tests, trial of enzyme replacement
Examples Peanut anaphylaxis, milk allergy Lactose intolerance, gluten sensitivity (non-celiac)

Oral Allergy Syndrome (Pollen-Food Allergy Syndrome)

This common condition occurs when proteins in certain raw fruits, vegetables, and nuts cross-react with pollen allergens. Symptoms are typically mild and confined to the mouth and throat.

Common Triggers:

  • Birch pollen: Apple, pear, peach, plum, carrot, celery, almond, hazelnut
  • Ragweed pollen: Banana, melon (watermelon, cantaloupe), cucumber, zucchini
  • Grass pollen: Tomato, potato, melon, orange

Symptoms: Itching, tingling, or mild swelling of lips, mouth, tongue, and throat immediately after eating raw forms of these foods.

Management: Cooking typically destroys the cross-reacting proteins, making the food tolerable. Severe reactions are rare but possible, especially with certain nuts.

The goal of our comprehensive food allergy programme is not just to diagnose and treat, but to empower patients and families with the knowledge and confidence to manage their condition effectively."
