Food allergies can present in early life and persist throughout childhood. It can be difficult to accurately diagnose food allergies due to a number of other differential diagnoses. A dietitian can help to identify potential food allergies through detailed symptom and diet histories. A nutritionally adequate treatment plan which may involve elimination diets can then be formulated. A dietitian’s expertise in infant and childhood food allergies will help to maintain steady growth and meet nutritional requirements for growth and development.
