    Genetic engineering of foods and latex-food allergies 

    Is there any relationship between genetic engineering of foods and latex-food allergies?

    After doing some research, we found that there is no direct relationship between genetic engineering of foods and latex-food allergies.

    What we learned about latex-food allergies from the greatest source of information that we found:

    “The only commercial source of latex in the marketplace is Hevea brasiliensis, the genus and species of rubber tree native to South America. When the gene stock for this tree was transported by the British to Asia, this tree began to express more of its “defense proteins” in response to the abrupt stress of a non-native environment. Included in these defense proteins were chitinase enzymes.

    When rubber trees are tapped for their sap, which in turn gets processed into latex, some of these chitinase proteins get carried over into the latex. One particular 3-dimensional section of these proteins is a fairly common trigger of antibody reactions in humans. This immune system reaction to a section of the chitinase protein constitutes a latex allergy.

    Certain foods have what is called a “Hevea-like” domain in their proteins. In other words, they have a 3-dimensional section of their proteins that is identical to the 3-dimensional section found in the chitinase proteins of latex. The existence of this identical spot allows for cross-reactivity between latex and certain foods.

    This cross-reactivity is called latex-food allergy, or latex-food syndrome. The primary foods associated with latex-food allergy are: avocado, kiwi, banana, and chestnuts and to a lesser degree, hazelnuts, peanuts, walnuts, almonds, passion fruit, strawberry, apple, fig, grapefruit, watermelon, pineapple, cherry. Pear, peach, mango, tomato, carrot, celery, sweet pepper, tomato, spinach, coconut, and paprika have at times also been associated with latex-food allergy.

    Although genetic modifications of food do introduce new proteins into those foods, we have not seen any research suggesting that these new proteins have any connection with latex cross-reactivity.”
