Eliminationsdiet

Eliminationsdiet, commonly referred to as an elimination diet, is a short-term dietary approach designed to identify foods that may cause adverse reactions in an individual. The method involves removing suspected foods or food groups from the diet for a defined period, followed by careful reintroduction to determine whether symptoms recur. It is used to evaluate suspected food allergies, intolerances, or symptom-based conditions such as irritable bowel syndrome (IBS) or atopic dermatitis.

Typical process: planning with a clinician or dietitian; elimination phase usually lasts two to six weeks, during which the chosen foods are avoided. Afterward, foods are reintroduced one at a time, often over several days, with close monitoring of symptoms. The goal is to identify specific triggers and develop a personalized long-term eating plan.

Commonly eliminated items include dairy products, gluten-containing grains, eggs, soy, nuts, shellfish, and certain food additives, though the exact list depends on the individual and professional guidance. During and after the process, attention to nutrition is important to prevent deficiencies.

Evidence and limitations: elimination diets can help pinpoint triggers in some people, particularly for suspected intolerances or IBS, but results vary, and a negative or positive response is not definitive without a controlled challenge. A formal supervised food challenge may be needed for confirmation of a true allergy.

Safety and suitability: elimination diets should be undertaken with healthcare or dietitian supervision, especially for children, pregnant people, or individuals with a history of severe reactions.
