When you have a food allergy, your body thinks certain foods are trying to harm you. Your body fights back by setting off an allergic reaction. In most cases, the symptoms are mild- a rash, a stuffy nose, or an upset stomach. A mild reaction is no fun, but it isn’t dangerous. A serious reaction can be deadly. But quick treatment can stop a dangerous reaction.
Allergies tend to run in families. You are more likely to have a food allergy if other people in your family have allergies like hay fever, asthma, or eczema (atopic dermatitis).
Food allergies are more common in children than adults. Children sometimes outgrow their food allergies, especially allergies to milk, eggs, or soy. But if you develop a food allergy as an adult, you will most likely have it for life.
