Certain fruits, vegetables, nuts, and seeds can contain pollen, especially if you have pollen allergies like birch, grass, or ragweed. This occurs due to cross-reactivity, where proteins in these foods are similar to those in pollen.
Here's a breakdown:
Foods Associated with Pollen Allergies (Cross-Reactivity):
-
Birch Pollen: The following foods are often associated with oral allergy syndrome in individuals with birch pollen allergies.
- Apple
- Almond
- Carrot
- Celery
- Cherry
- Hazelnut
- Kiwi
- Peach
- Pear
- Plum
-
Grass Pollen:
- Celery
- Melons (especially watermelon and cantaloupe)
- Oranges
- Peaches
- Tomato
-
Ragweed Pollen:
- Banana
- Cucumber
- Melons (especially honeydew and cantaloupe)
- Sunflower seeds
- Zucchini
Important Considerations:
- Severity: Reactions vary greatly. Some people experience only mild itching in the mouth, while others may have more severe allergic reactions.
- Cooking: Cooking can sometimes break down the proteins that cause the allergic reaction, making the food more tolerable.
- Not all people with pollen allergies will react to these foods. This is just a list of foods that have the potential to cause cross-reactivity.
- Pollen Contamination: Sometimes foods can have pollen on the surface due to environmental exposure (e.g., unwashed fruits and vegetables). Thoroughly washing produce can help reduce exposure.
- Honey and Bee Pollen: While bees collect pollen, the pollen found in honey and bee pollen supplements is typically flower pollen, not necessarily the allergenic tree, grass, or weed pollen. However, these products can still cause allergic reactions in some individuals. Consult with your doctor or allergist before consuming honey or bee pollen if you have known allergies.
