Understanding Food Allergy: Genes, Causes, and Natural History

This is an observational research study designed to understand why food allergies develop and what causes them to vary so much between people. Researchers will collect blood samples, genetic material, and detailed medical information from people with food allergies, their family members, and healthy volunteers. By studying the genes and immune system patterns of thousands of participants over 2 years, scientists hope to identify the underlying causes of food allergy and develop better treatments in the future.

Food allergies affect millions of Americans and have become increasingly common over the past 30 years, but doctors still don't understand why some people develop them or how to prevent or cure them. This study exists to fill that gap by investigating the genetic and environmental factors that lead to food allergy, so researchers can eventually develop more effective treatments.
