Diagnosis and Testing

Suspected food allergies should always be evaluated, diagnosed and treated by a qualified medical professional. Do not diagnose a food allergy on your own. Self-diagnosis can lead to unnecessary dietary restrictions and inadequate nutrition, especially in children.

More About Food Allergies

How to Read a Food Label

The only way to prevent a food-allergy reaction is to avoid the problem food. But you can’t know whether a food contains an allergen simply by looking at it.

Facts and Statistics

How many people have food allergies? What are the most common? These facts and statistics will help you better understand food allergies and anaphylaxis.

Milk Allergy vs. Lactose Intolerance

Milk allergy should not be confused with lactose intolerance. A food allergy happens when your immune system overreacts to a specific food protein. An intolerance is a digestive system issue.

Non-Food Allergens

Food is not the only allergen that can cause anaphylaxis. Learn about allergic reactions to medication, latex and insect stings.

Related Medical Conditions

Some medical conditions can produce symptoms similar to those of food allergies. Learn more about eosinophilic esophagitis, celiac disease and more.

Myths and Misconceptions

"It's okay to eat a little bit." "A reaction is always the same." Whether you live with food allergies or care for someone who does, brushing up on the facts is a great place to start.

Understanding FPIES

Food protein-induced enterocolitis syndrome (FPIES) is a rare type of delayed allergic reaction to food. FPIES most often occurs in infancy but may also happen in older children and adults.
