The Science of Cross-Reactivity in Food Allergies

Cross-reactivity occurs when the immune system **mistakes proteins in one food for another**, leading to allergic reactions even if the original allergen is avoided.

Why Cross-Reactivity Happens

Some allergens share similar protein structures, causing the immune system to **react to different but related foods**.

Case Study: Cross-Reactivity Between Birch Pollen and Apples

A **2023 study** in the Journal of Food Allergy found that **up to 70% of individuals allergic to birch pollen** also react to apples due to **similar protein compositions**.

Common Cross-Reactive Foods

Peanuts & Legumes: Cross-reacts with **lentils, peas, and soybeans**.
Tree Nuts: People allergic to **walnuts** may also react to **pecans and hazelnuts**.
Latex & Fruits: Latex allergy sufferers often react to **bananas, avocados, and kiwis**.
Shellfish & Dust Mites: Some shellfish-allergic individuals experience reactions to **dust mites** due to similar proteins.

How to Identify and Manage Cross-Reactivity

Take **allergy tests** to determine cross-reactive sensitivities.
Maintain a **food diary** to track unexpected reactions.
Consider **oral immunotherapy** to desensitize the immune system.

Future Research on Cross-Reactivity
