Food allergy symptoms range from mild itching and indigestion to life-threatening conditions–so don't ignore them. Some allergies are quite common, while others are difficult to diagnose. 

There's no cure for food allergies, there are ways to prevent or manage the symptoms. Yale Medicine physicians are experienced with the latest tests and treatments.

The most common food allergies are to peanuts, milk and eggs.

Peanut allergies can be severe and pose some of the most serious and well-known risks to patients. Milk and egg allergies tend to be especially complex.

“Milk allergies are actually quite complicated to understand,” says Stephanie C. Eisenbarth, MD, PhD, assistant professor of Laboratory Medicine, Immunobiology and Allergy & Clinical Immunology at Yale Medicine School of Medicine. 

Similarly, egg allergies can take different forms. Some people react to eggs when they are present in baked pastries, and some people react to eggs when they are cooked (e.g. hard-boiled eggs), making monitoring and diagnosis difficult.
