Food allergy (FA) is a medical condition that affects 15 million people in the United States. Allergic reactions are a result of exposure to a food that causes a harmful immune response. Currently there is no cure for food allergy—making strict avoidance of specific foods the gold-standard of food allergy management.

The Food Allergy Clinic at Cincinnati Children’s Hospital hosts a diverse population, which serves to inform the basis for our observational research and clinical trials. The Assa’ad Lab actively engages in research that aims to improve our understanding of the natural development of FA, and investigate novel treatments to achieve optimal health outcomes. 

The impact of our work is far reaching, with projects that address FA management, health disparities, and health-related quality of life.
