Wheat-Free Diet

Allergy to wheat is one of the most common food allergies in infants, young children, and adults. A wheat-free diet excludes wheat and all products derived from wheat.

Why do people follow this diet?

Most people who are allergic to wheat are allergic to the protein in wheat. Exposure to wheat dust can cause respiratory symptoms, including asthma in susceptible people. In rare cases, hydrolysed wheat in body cream has caused hives.

What are the symptoms?

Wheat allergy symptoms may include any of the common symptoms of food allergies, including skin rashes or hives, gastrointestinal distress, breathing problems, or many other possible symptoms. In severe cases, a life-threatening reaction called anaphylaxis may occur. To avoid an allergic reaction to wheat, ask about ingredients at restaurants or others’ homes, and read food labels. Be aware that processed foods can be a source of hidden (unlabeled) wheat. For example, “flour” usually means wheat. Individuals who have coeliac sprue (gluten-sensitive enteropathy) need to avoid all foods containing gluten, including wheat. A gluten-free diet excludes all foods containing wheat, rye, barley, and buckwheat. The following is a list of foods that should be avoided on a wheat-free diet. This is not a complete list and it would be prudent to consult with a health care professional for more information.
