What Is Food Allergy?

Food allergy is an abnormal immune response to food proteins that may damage the small intestinal  lining and produce malabsorption of food. The reaction is usually delayed which makes it difficult to identify the offending food that is causing symptoms.

Q: How does food allergy develop?

A: The gastrointestinal tract serves not only to digest and absorb foodstuffs but also to protect the body from unwanted substances. When allergic food substances are eaten, the immune response that is triggered in the gut produces inflammation with symptoms such as pain, vomiting and loose bowels.

Inflammation causes swelling of the gut lining that can interfere with the passage of nutrients through it to the body which results in malabsorption. Malabsorption deprives the body of nutrients needed for normal function.

Symptoms other than digestive may involve skin rashes, hives, and respiratory difficulties that can be distressing and life-threatening.
