Some people with Type 1 (immediate) latex allergy also react to certain fruits and vegetables, including banana, avocado, tomato, potato, kiwi, chestnut, lychee, papaya, passion fruit, fig, melon, mango, pineapple, peach and lettuce.
This is known as cross-reactivity, where the proteins in latex have a similar structure to the proteins in these foods. If you are allergic to any of these foods, you may also be allergic to latex, and vice versa.
Symptoms normally affect the mouth after eating the food and are usually mild. They can include tingling or itching in the lips, tongue or throat. More serious reactions can occur, so discuss this with your doctor. You can also discuss which foods might cause you a problem.
Raw potatoes can cause contact reactions when people with latex allergy peel potatoes, but cooked potato is not usually a problem.
Not everyone with latex allergy has latex-food syndrome, and most people with latex-food syndrome will only react to a small number of foods.
