Food allergy can be a trigger in asthma.
Therefore, worsening of asthma through an increase of BHR appears possible, especially in infants who have more frequently positive food allergy tests than the older patients, even if a direct relationship between ingestion and symptoms is not obvious. DBFC should only be performed in an hospital, where emergency care is immediately available, and therefore must be restricted to limited cases and in very selected conditions. It must be borne in mind that any diet can cause rapid deficiencies in infancy. BOCK S.A. Respiratory reactions induced by food challenges in children with pulmonary diseases Pediatr. In C.E.
