An elimination iet 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. When the mechanism is unknown, but a food is suspected, the mechanism may be described as a food sensitivity or a food hypersensitivity. Elimination diets typically involve entirely removing a suspected food from the diet for a period of time from two weeks to two months, and seeing whether symptoms resolve during that time.
