Practice Paper of the Academy of Nutrition and Dietetics: Role of the Registered Dietitian Nutritionist in the Diagnosis and Management of Food Allergies

Abstract Incidence of food allergy has increased significantly over the past decade and represents an important health issue for millions of Americans. Diagnosis of immunoglobulin E−mediated food allergies is sometimes difficult because blood and skin tests have high rates of false positives, and oral food challenges are uncommon due to the expense and potential for serious reactions. Accurate diagnosis is crucial to avoid unnecessary dietary restriction, especially in children. Because registered dietitian nutritionists often work independently, receiving referrals for dietary education and guidance for a patient who is followed by one or several other practitioners, navigating the data available and making the appropriate follow-up contact optimizes treatment. The purpose of this paper is to provide guidance to the registered dietitian nutritionists and nutrition and dietetics technician, registered on appropriate and evidence-based nutrition counseling for diagnosis and management of food allergies.
