Wheat is recognized as one of the eight common food allergens that can trigger allergic reactions in sensitive individuals. These allergens are significant because they are frequently responsible for food allergies and affect a substantial portion of the population. The most notable allergens include peanuts, tree nuts, milk, eggs, fish, shellfish, soy, and wheat.

Understanding this classification is crucial for food handlers, as they must be aware of these allergens to ensure safe food preparation and service, preventing cross-contamination and protecting those with dietary restrictions. Awareness of wheat as a common allergen also emphasizes the importance of labeling and proper communication about food ingredients in restaurants and other food service settings.
