Trial-Elimination Diet After Receiving The Results


The foods with elevated IgG levels will show in the red column of your report. They may cause symptoms, and so it is best to eliminate them in the long-term. However, you might not actually experience discomfort or symptoms with these foods. The trial-elimination diet is the best way to understand which foods in your report are directly related to your symptoms.

Here’s how to do it:


1. Eliminate all foods in the red zone for at least a month. This will help you recover from any food-related symptoms.


2. Reintroduce one of the foods in the red zone and wait for 72 hours. If you feel that the symptoms are returning, do not try that food again.


3. If your symptoms return after 72 hours, wait at least a month before trying again.


4. If your symptoms DO NOT come back after you process that food, immediately introduce another food, wait for another 72 hours, and repeat the process.


It might sound hard to perform the trial-elimination diet. But thanks to the precision of Microarray technology, the average number of foods you’ll have to work with is six or seven. Some of these foods might be easy for you to avoid, so you won’t even have to trial-eliminate them.


For example, if your results show you are intolerant to wheat, leek, oysters, lentils, and chicken, and you don’t like oysters and leek, simply remove those foods from your diet and perform the trial-elimination diet for wheat, lentils, and chicken.



Caution: You are NOT recommended to reintroduce a known food allergy. Ask your healthcare provider to discuss the signs and management of immediate hypersensitivity reactions before reintroducing an allergen following an elimination diet. If the reintroduction of food causes an immediate allergic reaction such as swelling of the face, mouth, or tongue; wheezing; rash/hives; or other allergic symptoms, you must seek treatment as soon as possible.

How long do I have to avoid these foods?


You can perform the trial-elimination diet whenever you think it is necessary. And you can continue to eat any foods that do not give you symptoms. In our experience, most IgG-mediated allergies that cause symptoms are due to enzyme deficiencies and they rarely show changes.
