Introduction
The appearance symptoms of food intolerance are always delayed (several hours to days after consumption of the foodstuff), and an association with a disease picture is often very difficult to establish, even for specialists. Often, the production of antibodies augments the symptoms of existing inflammatory disease or the symptoms become recognisable for the first time.
For example, associations between food intolerance and gastrointestinal disease, rheumatoid arthritis and skin disorders have been described. Antibody production also has an aggravating effect on the symptoms of migraine, ADHS or autism (strength and frequency of attacks). It can also influence fertility and aging or cause substantial weight changes.
