Unlike wheat intolerance, a wheat allergy is an immune system response to wheat specifically which signals the body to cause a reaction.
True wheat allergy is most common in young children and rarely seen in adults. The good news is that children often outgrow wheat allergy by the age of two, and anaphylactic reactions are very rare.
Being diagnosed with a wheat allergy requires the complete exclusion of wheat from the diet. This means excluding even traces of wheat from the diet although other grains can still be consumed, such as, rye and barley.
Wheat-free foods are available from health food stores, some specialty stores and supermarkets; however the range available can vary.
Substitutes for wheat flour include:
Cornflour
