Food allergies seldom cause asthma symptoms to get worse. Common food allergies consist of nuts, eggs, milk, seafood and peanuts. Food allergies are more common in children ages five and below.

If certain foods are assumed to trigger troubles, they can be removed from the diet. But, it is essential that diet changes be made only when there is strong proof that these foods are causing problems. If food allergies are acause for concern, the case should be evaluated by certified allergist/immunologist. This specialist can associate the information from a comprehensive diet history, allergy (skin) testing and food challenges, if required.
