Wheat Allergies and Wheat Allergy Symptoms

What are Wheat Allergies?

Wheat allergy is a type of food allergy, that is caused by an abnormal immune system reaction to one or more proteins that are found in wheat. In order to develop a wheat allergy, you need to eat wheat at least once. This allows the immune system to be exposed to the protein. After the body is exposed, the immune system then learns to identify these proteins, and when these proteins are introduced in the body again, the body attacks them with histamines triggering an allergic reaction. Additionally, wheat allergies are one of the eight most common food allergies , and is more common in children. It affects about six percent of children under the age of three and is much less common in adults. Wheat allergies are often confused with Celiac Disease, but they are not the same thing.
