Food Intolerance


Sometimes, certain people have an unusual reaction to a certain food or food ingredient!

What is a food intolerance?

Food intolerance is a delayed reaction of the body to a certain type of food or food ingredients, during which specific IgG antibodies are created. It is a low-grade, long-term chronic inflammatory reaction that lasts as long as the food that triggers the reaction is consumed.

This test detects exactly these IgG4 antibodies, giving a clear picture of the intensity of the body’s reaction to the specific type of food.


Unlike allergies, which usually have an acute and intense onset of symptoms (2 hours or less) and can also be caused by the presence of traces of allergens, intolerance is slower, with a delayed and sometimes unrecognizable onset of symptoms (up to 72 hours), the intensity of which also depends on the amount of food consumed.

Although the symptoms in many cases can be very similar, with the help of this proven and certified test, a clear differentiation is made and it is possible to quickly and accurately determine the cause of the appearance of the symptoms.

Inflammatory processes can manifest in different organs and systems and cause a wide range of symptoms.

What after receiving the result?

Elimination phase

The food for which a positive result was obtained should be completely avoided, for 2 to 6 weeks depending on the reaction. In this way, the resulting inflammatory processes can be reduced or completely withdrawn.

The remaining foods to which there are no elevated levels of IgG antibodies can be consumed in a 4-day rotation cycle. (For example, if certain types of food are eaten one day, they should be avoided for the next 3 days.) This helps prevent the development of new delayed body reactions.

Food reintroduction phase

In this phase, a provocation diet is started, through which the avoided foods are gradually included.

Foods are introduced one at a time, in order to more easily identify foods that still cause symptoms. If a reaction occurs again, the food on the menu is avoided.

Stabilization phase

During this phase, foods that cause a reaction during the re-introduction process are avoided for at least one year in order to reduce IgG antibodies and improve the body’s condition.

After this, the patient starts the food introduction phase again. Some patients may need to avoid one or more foods for life.
