Foods that Can Make Seasonal Allergies Worse
Not all foods, even healthy ones, are good for allergies. In fact, some foods seem to make seasonal allergies worse. Fruits or vegetables that grow from flowers can sometimes produce the same allergic reaction as pollen (this is called cross-reactivity). Doctors are not sure why this happens, but they do know that it can help those who suffer from disruptive allergies to remove selectively certain foods from their diets, then reintroduce each food one at a time to if each one produces an increase in symptoms. If one food does, it should be avoided during the allergy season.
Foods that are known to cross-react with ragweed include cantaloupe, watermelon, and bananas. Foods known to cross-react with tree pollen include apples, cherries, peaches, carrots, and potatoes. Foods known to cross-react with a broad range of pollens include pears, kiwis, nectarines, celery, peppers, and tree nuts.
Cooking seems to deactivate the allergens in these foods, so those who don't want to skip them entirely can make cooked dishes such as peach cobbler, banana bread, and watermelon sorbet.
