People allergic to tree pollen such that Birch, Alder, Cypress, Elm, Hazel, Cedar, Chestnut, Elder, Hickory, Oak, Pecan, Poplar, Sycamore, Willow, or Ash should avoid known cross-reactors of Tree pollen. Cross-reactors are foods that have similar protein profiles as those of severe allergens such as pollens of Birch and Alder and confuse the immune system into over-reacting. The tolerance for most foods in this list, except celery and nuts, can be improved if they have been cooked, baked, or roasted. This is because heat can break down some of the protein bonds making it dissimilar to the confusing allergen.
Do you know any other foods to avoid if you suffer from seasonal tree pollen allergies?
