“This office was AMAZING! I am so very impressed. I have never had more of a thorough doctor. The office staff was great too. I brought a newborn in and they all treated the situation of me having my baby there great. She made sure to lay everything out on the table of what could be the cause of my symptoms. She was so helpful.”

Latex-Fruit Syndrome Symptoms

Latex-Fruit Syndrome Treatment

Latex-fruit syndrome is a condition in which a latex allergy causes you to also react to certain fruits, vegetables and nuts. Certain foods, such as bananas and avocados, contain proteins that are structured similarly to latex, causing them to be cross-reactive with latex. This means that your immune system may recognize these foods as latex.

Latex-fruit syndrome occurs in roughly 30-50% of people with latex allergy. Individuals with latex-fruit syndrome can experience allergic reactions after eating, touching, or smelling cross-reactive foods. It is also possible for individuals to have a fruit allergy that is cross-reactive with latex. This occurs in roughly 10% of people with a fruit allergy.

Latex-Fruit Syndrome Foods List

Several foods have been implicated in latex-fruit syndrome. Bananas, chestnuts, avocados, and kiwi have a particularly high cross-reactivity with latex, meaning that individuals with a latex allergy are more likely to experience allergic reactions when exposed to these foods.

Apples, tomatoes, potatoes, carrots, celery, melons, and papaya are said to have moderate cross-reactivity with latex. While individuals with latex allergy are less likely to experience allergic reactions to these foods than the highly cross-reactive foods listed above, allergic reactions are still possible.

Many other foods have low or undetermined cross-reactivity with latex, including many common fruits, vegetables, nuts, and seeds not listed above. You may experience latex-fruit syndrome when exposed to apricot, buckwheat, cassava/manioc, castor bean, cherry, chickpea, citrus fruits, coconut, cucumber, dill, eggplant, fig, goji berry or wolfberry, grape, hazelnut, Indian jujube, jackfruit, lychee, mango, nectarine, oregano, passion fruit, peach, peanut, pear, peppers (cayenne, sweet, or bell), persimmon, pineapple, pumpkin, rye, sage, strawberry, shellfish, soybean, sunflower seed, tobacco, turnip, walnut, wheat, or zucchini. However, reactions to these foods are unlikely compared to foods with high and moderate cross-reactivity.

Latex-Fruit Syndrome Symptoms

Latex-fruit syndrome can cause allergic reactions that are similar to latex allergy, contact dermatitis, or food allergy. Individuals with latex allergy should be aware that latex-fruit syndrome can be quite severe, and even anaphylaxis is possible with exposure to foods that are cross-reactive with your latex allergy.

‘Classic’ latex allergy symptoms include hives, itching or flushing, tightness in the throat, or wheezing. These symptoms can occur when a cross-reactive food touches your skin or mucous membranes, or when you smell or inhale particles from a cross-reactive food.

Contact dermatitis symptoms can occur in latex-fruit syndrome when your skin comes into contact with a cross-reactive food. Inflammation, itching, pain, rash, redness, and swelling are the typical symptoms of a contact reaction.

You may also experience food allergy-like symptoms when eating a cross-reactive food. Itchiness, redness, swelling, or irritation on the lips, mouth, tongue, or throat are common reactions. Nausea and stomach ache are also possible, though less common.

Latex-Fruit Syndrome Treatment

At the present moment there is no cure for latex-fruit syndrome. Individuals with latex-fruit syndrome are advised to avoid foods that are cross-reactive with their latex allergy, and to carry epinephrine in the event of a serious reaction.

Antihistamines may be effective in relieving mild latex allergy symptoms when they occur. Dr. Cajigal can offer personalized advice on how to manage your latex allergy, and latex-fruit syndrome. Get in touch with us at St. Louis Family Allergy to learn more!

"Dr. Cajigal was friendly, professional, and informative. She took the time to explain the tests and what was going on with my allergies. She is so knowledgeable and really cared about how I was feeling. I would highly recommend this practice if you suffer from allergies and asthma."

- Sue D, July 2020

“Dr Cajigal is a great listener. She trusts her patients instead of treating them as if they are not the experts of their own bodies. I really appreciate that (many doctors do not have that quality). She also immediately treats the symptoms instead of waiting to see if things clear. I use her for my children and myself. We have never left her office feeling as if it was a waste of time.”
