Millions of people worldwide live with food allergies, including all those at risk for life-threatening anaphylaxis. The lack of a standardized food vocabulary impacts food source risk assessment, food hazard control, consistent food allergy policy implementation and food-allergy research. The Canadian Healthy Infant Longitudinal Study (CHILD) examines causal factors of asthma and allergy during childhood development. The development of FoodON will benefit food allergy research by standardizing food descriptors across child cohorts, enable the correlation of food antigens with biological causation of immune response, and streamline guidelines for parents.
