Abstract

In the professional medical and scientific world, there is not many interest in the correlation of food intolerance and autoimmune diseases. However there is a lot of evidence that e.g. gluten or gliadine can induce autoimmmune diseases: example the interest in coeliac disease and autoimmunity. There is however a lot of informationavailable about leaky gut and autoimmunity.

We performed an observational study in our data base;, where we selected 100 patients with manifest autoimmune disease with clear symptoms and autoimmune antibodies in the form of positive anf more tehn 160 titer. These patients were compared with 25 control patients without any autoimmunity.

We could clearly find a difference in food intolerance profiles when we compared AI patients with people without any AI. Overall there is a much greater reaction to several food epitopes, which can be observed on the level of specific antibodies tot he food epitopes. These igG levels for specific food antibodies are significantly higher in the patient group then in the control group. We can also see that some food epitopes provocate a very pronounced reaction, while other show no increased level of igG. Among the most reactive food epitopes are caseine, cow milk, wheat, gliadine, white of egg and rice. A variable reaction can bes een on nuts e.g.; walnuts and almonds. Almost no antibody reaction is noticed on vegetables, fish and meat products, who seem tob e immunologially very neutral.

We conclude that food intolerance test is very important tool in patients with AI disease, and should be performed in each patient to tailor an individual diet program, which if properly followed, could relieve symptoms and probably stop or slow the the progression of the autoimmune disease.

Also interesting for global research in AI disease is the fact that food is probably an important trigger for autoimmunity in vulnerable patients. More research on great scale and multicenter around this topic is mandatory and urgent.
