Why Strawberries Might Make Your Child’s Tongue Itch

A Common but Confusing Reaction

It can be alarming when a child says their tongue feels itchy after eating strawberries.

While most enjoy strawberries without issues, some children react differently.

One likely cause is Oral Allergy Syndrome (OAS)—a mild allergic reaction where “the immune system confuses certain proteins in fruits or vegetables with pollen allergens.”

Recognizing Symptoms of OAS

OAS symptoms often appear within minutes and include “itching or tingling in the lips, tongue, throat, or inside the mouth.”

Mild swelling may occur, but symptoms usually fade quickly.

Still, parents should watch for serious signs like difficulty breathing or swallowing, which may suggest a stronger allergic reaction.

Why It Happens—and Why Kids Feel It More

Strawberries share proteins with certain pollens—especially birch. This pollen-fruit cross-reactivity can confuse the immune system.

“The immune system mistakes the fruit proteins for pollen,” triggering symptoms.

Children may experience OAS more often because “their bodies are still ‘learning’ what is safe,” making them more reactive to new foods.

Interestingly, cooked or processed strawberries (like in jam or baked goods) rarely cause OAS.

That’s because “cooking or processing strawberries often changes these proteins,” making them less irritating.

Managing Reactions and When to See a Doctor

Avoiding raw strawberries is the simplest way to prevent symptoms. Keeping a food diary and teaching children to speak up about symptoms can also help.

“Antihistamines may help ease mild reactions,” but if symptoms are severe or include trouble breathing, seek medical care immediately. An allergist can confirm the cause and guide you through safe management.
