Once determined, the food/foods which originate the intolerance should be eliminated from your diet for a period of time, which may vary from 4 to 12 weeks, depending on the intensity level of the intolerance.
The food/foods can later be gradually reintroduced in the diet, until your body does not recognise it as "dangerous" anymore.
Further information on the elimination diet and more detailed guidelines on the reintroduction of food/foods can be found in the booklet which comes together with your test results.
