What Is A Seed Allergy?

A seed allergy is any physical reaction after consuming seeds or their products. Seed allergies are increasing in the United States. Sesame, mustard, sunflower, and poppy seeds cause the most allergic reactions. While sesame allergy is the most common seed allergy, mustard seeds usually produce more severe allergic reactions. Those allergic to one seed have a high chance of being allergic to other seeds.

Symptoms of a seed allergy include:

  • Hives
  • Itchy mouth and skin
  • Swelling of the lips
  • Sudden drop in blood pressure
  • Loss of consciousness
  • Wheezing and difficulty breathing

For severe allergies, it’s best to avoid all seeds.

Products You Should Avoid That May Contain Seeds

  • Breads
  • Sauces & Salad Dressings
  • Sesame Oil
  • Granola Products
  • Soups
  • Canola Oil
  • Cereals
  • Margarine
  • Cottonseed Oil
  • Rice Cakes
  • Seed Oil Based Cosmetics
  • Pumpkin Seed Oil
  • Veggie Burgers
  • Sunflower Oil
  • Grapefruit Seed Oil

Seeds come in various forms, so it’s important to read the labels of products you consume. While this allergy is becoming more severe, the FDA doesn’t require seeds to be labeled as allergens on packaged goods. If you have this allergy, you should read every ingredient on the labels of foods you eat.

Also, beware of vegetable oils. Most vegetable oils come from seeds. Sunflower oil, canola oil, and sesame oil are common types of vegetable oils. As an alternative, use olive oil or peanut oil when cooking.

Diagnosing Seed Allergy

A food challenge or allergy provocation test is the most accurate way to diagnose seed allergy. A Board Certified allergist will administer the allergen in a clinical setting to see if a reaction occurs. In the event of a severe allergic reaction, your allergist will have emergency tools close by, such as an epinephrine injection.  

Seed Allergy Treatment

Allergy medications can treat symptoms related to seed allergy. Some antihistamines can help itching and swelling. Applying a cold compress to the skin can also help with hives and other skin irritations. Avoid scented products that irritate the skin more.

For breathing problems and other severe allergic reactions, a doctor can prescribe medications. An inhaled corticosteroid may be necessary to treat wheezing. If reactions cause anaphylaxis, an epinephrine injection can treat symptoms before medical personnel arrives.
