Food Allergies 101: What You Need to Know

What Are Food Allergies?


An allergic reaction to food is an immune system response occurring soon after eating certain foods.

In extreme cases, food allergies lead to anaphylaxis. Seek medical assistance at the nearest healthcare facility to avoid further complications.

Common food allergies include:

  • Peanuts 
  • Tree nuts 
  • Shellfish 
  • Fish
  • Milk
  • Eggs
  • Wheat 
  • Soy 

Food allergy symptoms include:

  • Food allergy hives
  • Itching
  • Swelling 
  • Nausea
  • Vomiting 
  • Abdominal pain 
  • Difficulty breathing 
  • Rash from a food allergy

Did You Know?
In 2024, it's projected that approximately 17 million individuals in the United States will have a confirmed food allergy.

Food Allergy Testing

Testing for food allergies is essential in identifying the signs and symptoms. There are several standard methods available for testing that produce accurate results.

  • Skin Prick Test (SPT)

    • This test is the most common and usually the first test conducted.
    • A tiny needle applies a small amount of the allergen extract to the skin.
    • If a raised, itchy bump forms at the site, it indicates a positive reaction.

  • Blood Tests (Specific IgE Tests)

    • This test measures the specific antibodies (IgE) produced in response to major food allergens.
    • Standard blood tests include the ImmunoCAP and the RAST (Radioallergosorbent) tests.
    • Results come in numerical values that indicate the level of IgE antibodies present.

  • Oral Food Challenge (OFC)

    • This approach is considered the most accurate test and utilized under medical supervision.
    • To check for allergic reactions, the patient ingests tiny amounts of the suspected food allergens.

  • Elimination Diet

    • This method involves removing specific foods from the diet for some time and reintroducing them to observe any allergic reactions.

  • Component-Resolved Diagnosis (CRD)

    • This method is a blood test that identifies specific protein components of allergens. It can help pinpoint the exact proteins causing the allergy.

  • Food Diary and Symptom Log

    • A detailed record of food intake and associated symptoms can provide valuable information for diagnosing food allergies.

  • Provocation Testing

    • This test is a controlled exposure to the suspected allergen in a clinical setting to observe the body's reaction.

Food Allergy Treatment

Understanding how to manage and treat food allergies is crucial for individuals and their families.

  • Diagnosing Food Allergies

    Accurate diagnosis is essential for effective treatment. A food allergist uses a combination of medical history, physical examinations, and specialized tests like skin prick and blood tests to identify specific allergens.

  • Importance of Allergist Consultation

    Consulting an allergist is crucial for comprehensive allergy management. They can provide personalized advice, conduct tests, and help create a customized treatment plan for food allergies.

  • Avoidance Strategies

    The most efficient way to prevent allergic reactions is to avoid allergenic foods. This approach involves careful reading of food labels, asking about ingredients when dining out, and being aware of cross-contamination risks.

  • Epinephrine and Anaphylaxis

    In severe allergic reactions (anaphylaxis), prompt action is vital. Epinephrine is an ideal first-line treatment. It rapidly reverses symptoms and buys time for further medical intervention.

  • Oral Immunotherapy: OIT

    Oral immunotherapy involves exposing the individual to small, controlled increments of the food allergen to desensitize their immune system. This method can be a game-changer for those with severe allergies. At this time, AAAC is not offering food allergy oral immunotherapy in the office.  We recommend JHACH Food Allergy Clinic.

  • Medications for Food Allergies

    Antihistamines and corticosteroids can help manage milder allergic reactions. However, these food allergy treatments are not substitutes for epinephrine in cases of anaphylaxis.

  • Dietary Modifications and Nutritional Support

    A registered dietitian can guide you on maintaining a balanced diet while avoiding allergenic foods. They can also recommend suitable alternatives and supplements.

  • Emergency Action Plans

    A well-defined emergency action plan is crucial for individuals with food allergies. This plan outlines steps to take in case of accidental exposure. One example is preparing a list of foods that cause hives.

Frequently Asked Questions About Food Allergy Treatment

  • What is the first-line treatment for food allergies?

    The primary treatment for food allergies is strictly avoiding the allergen. This method involves reading labels, being cautious about cross-contamination, identifying food allergy signs, and making informed food choices.

  • Can food allergies be outgrown?

     Some food allergies, especially in children, may be outgrown over time. However, allergies to certain foods like peanuts, tree nuts, and shellfish may persist into adulthood.

  • Are there any medications for all types of food allergies?

     Antihistamines can help relieve mild allergic reactions but are not a substitute for avoiding the allergen. Epinephrine auto-injectors are ideal for severe allergic reactions. 

  • How can I manage accidental exposure to allergens?

     It's crucial to have an anaphylaxis action plan, which may include using an epinephrine auto-injector and seeking immediate medical attention. Always inform restaurant staff and caregivers about your food allergies.

  • What is oral immunotherapy for food allergies?

     Oral immunotherapy, also known as OIT, is a treatment method that involves gradually increasing the intake of small amounts of the food allergen to which a patient is allergic. Doing so builds the body's resistance to the allergen slowly, leading to desensitization over time. 

  • What is the most common food allergy?

    Peanuts are the most common culprit of food allergy.
