What is the Elimination diet?

The Elimination diet equivalent to a test for sensitivity (e.g. allergy or intolerance) to some potential food diseases. The test relates the disease with food, which over a period of 10 to 14 days the person is deprived of certain foods in order to determine, after this period, a possible improvement and so correlate with the disease, thereby assisting in treatment of the withdraw the food key to a person’s diet disease.


This facilitates the identification of foods that cause health problems, such as dietary intolerance, allergy, diarrhea, constipation, headaches and migraines, ear infections, colds and nasal congestion, acne, asthma, urticaria, indigestion, ulcers and weight changes.


The elimination diet should be accompanied by a health care professional. This diet should be avoided in the case of severe allergies to avoid severe reactions (e.g. asthma attacks). People who follow this diet for health reasons (medical advice) should carefully read the labels on the packaging of food products. Since diet is very strict, people should avoid eating at friends’ homes that are not properly informed and in public places (restaurants, cafes and canteens).

Should be aware that by excluding certain foods, you may be depriving the body to get certain nutrients, so it is advised to replace them, especially vitamins (e.g. if a person is allergic to dairy products, must consume food supplements with calcium) and thus correct the vitamin deficit.

Children, infants and breast-feeding women should be strictly controlled by a health care professional to not lead to growth or inappropriate development.

Side effects

People who are subject to this diet may suffer nutritional disorders because it is a very restricted, long term diet  and because there is always a risk factor for a severe reaction by introducing a suspect food in the diet.
