Food allergy.

Food allergy is now known to encompass a number of distinct clinical entities that follow the ingestion of specific food or food additives. Research continues to shed light on immediate reactions to foods and food protein-induced enterocolitis of newborns and infants. Adverse reactions to food additives remain an area of health concern. Studies of food allergies have entered an era in which improved clinical design is the hallmark of the research and conclusions may now be drawn reliably.
