Oligoantigenic diet

An oligoantigenic diet is a diet with the least possible risk of allergic reaction. It is used to eliminate food allergies as the cause of a particular illness. It has been used to treat Crohn's disease, migraine and ADHD. However, treatment of ADHD with these diets is a controversial topic, as studies used to test these claims involved children who were allergic to foods. These studies also showed no improvement in measures of hyperactivity or inattention by unbiased observers. Only parental ratings indicated that children's behaviour had improved.1
