If your child complains of an itchy or tingly tongue after eating strawberries, it’s often due to a mild condition called Oral Allergy Syndrome (OAS)—a reaction that happens when the immune system confuses proteins in raw fruits with those in pollen.
What’s Happening
In OAS, the body mistakes strawberry proteins for pollen, triggering itching or tingling in the mouth, lips, or throat. Symptoms usually appear within minutes and fade quickly once the food is swallowed or removed.

Common Symptoms
Itchy or tingly tongue, lips, or throat
Mild swelling in the mouth area
 Call for urgent help if breathing trouble, severe swelling, vomiting, or hives occur—these may signal a serious allergic reaction.

Why Kids React
Children’s immune systems are still learning to distinguish safe foods. Kids with seasonal pollen allergies (especially birch) are more likely to react to strawberries, apples, or peaches.
Why Jam Usually Doesn’t Trigger It
Cooking or processing breaks down the proteins that cause OAS, so strawberry jam or baked goods rarely cause symptoms.

What Parents Can Do
Avoid raw strawberries if symptoms occur; try cooked versions.
Keep a food diary and watch for patterns.
See an allergist for testing and management tips.
OAS is typically mild, and with awareness and guidance, most kids can keep enjoying strawberries—just in the right form.
