Food allergies affect around 4 percent of adults and 5 percent of children in the United States.
A food allergy occurs when the body’s immune system triggers an abnormal response to food.
Symptoms of allergic reaction to a specific food range from sneezing and nasal congestion to anaphylaxis.
Anaphylaxis is a potentially life-threatening response that impairs breathing and sends the body into a state of shock. Anaphylaxis to food leads to around 30,000 visits to the emergency room, 2,000 hospitalizations, and 150 deaths each year in the U.S.
There is currently no cure for food allergies, and avoiding the food to which you are allergic is the only way to prevent a reaction.
