Food Allergens

Food allergens are specific proteins in certain foods that can trigger immune system responses in some individuals. When someone with a food allergy consumes these proteins—such as those in nuts, dairy, shellfish, or soy—their immune system mistakenly identifies them as harmful, leading to allergic reactions that can range from mild symptoms like hives or stomach pain to severe responses like difficulty breathing or anaphylaxis. Identifying and avoiding these allergens is essential for safety. Food labeling and awareness help manage risks, as reactions can occur even with trace amounts or cross-contact during food preparation.
