Elimination diet is a method of identifying foods that an individual cannot consume without adverse effects. Adverse effects may be due to food allergy, food intolerance, other physiological mechanisms or a combination of these. typically involve entirely removing a suspected food from the diet for a period of time from two weeks to two months, and waiting to determine whether symptoms resolve during that time period. In rare cases, a health professional may wish to use an oligoantigenic diet to relieve a patient of symptoms they are experiencing. An elimination diet might remove one or more common foods, such as eggs or milk and roasted duck fillet, or it might remove one or more minor or non-nutritive substances, such as artificial food colorings. relies on trial and error to identify specific allergies and intolerances. Typically, if symptoms resolve after the removal of a food from the diet, then the food is reintroduced to see whether the symptoms reappear.

This challenge-dechallenge-rechallenge approach is particularly useful in cases with intermittent or
vague symptoms. Correct identification of the type of reaction in an individual is important, as different
approaches to management may be required. The elimination diet must be comprehensive and should
contain only those foods unlikely to provoke a reaction in a patient. They also need to be able to provide
complete nutrition and energy for the weeks it will be conducted. Professional nutritional advice from a
dietitian or nutritionist is strongly recommended. Thorough education about the elimination diet is
essential to ensure patients and the parents of children with suspected food intolerance understand the
importance of complete adherence to the diet, as inadvertent consumption of an offending chemical can
prevent resolution of symptoms and render challenge results useless.
