The science behind every major food allergen.
Plain-language breakdowns of the top 14 allergens — hidden names, common sources, the protein families behind reactions, and the cross-reactivity clusters that explain why latex relates to avocado, dust mites to shrimp, and birch pollen to apples.

Why some allergies travel in clusters
Allergic reactions are about proteins, not foods. When two foods share a similar protein, the immune system can mistake one for the other. These are the major scientifically-recognized clusters.
Educational, not medical advice.
This library is built for parents, school staff, and clinicians as a starting point. Cross-reactivity is highly individual — a positive lab test does not always mean a clinical reaction, and vice versa. Always work with a board-certified allergist on diagnosis, food challenges, and management plans.
