Cross-Reactivities Among Pollen and Foods

If you have noticed that you have allergies to specific environmental allergens AND to certain types of food, you are not alone.  Research has shown clinical and immunochemical similarities between taxonomically-related and unrelated allergens.

Research has also shown that, for some patients, food allergies may result from primary sensitizations to grass, tree, or weed pollens containing similar allergenic components.

Cross-reactive allergens have been identified among the following pollens and foods:

  • Birch, Alder and Hazelnut Pollens with Apple, Celery, Cherry, Peach, Pear, and Hazelnut Foods
  • Grass Pollens with Celery, Cereal Grains and Potato Foods
  • Mugwort Pollen with Apple, Carrot, Celery, Kiwi, Orange and Peanut Foods
  • Ragweed Pollen with Banana, Cantaloupe and Watermelon
