In patients with allergies to airborne particles, the appearance of oral itching or tingling after eating fresh fruit or vegetables is enough to suspect OAS [3].
What is IgE mediated food allergy?

The most common foods involved are cow's milk, hen's egg, legumes (peanuts and soybean), fish, shellfish, and wheat. The allergens contained in these foods not only elicit allergic reactions in the gastrointestinal tract but also often cause urticaria, atopic dermatitis, and bronchial obstruction. With a few exceptions, most children outgrow class 1 food allergy within the first 3 to 6 years of life [7].
