The discovery of IgE in the mid·1960s resulted in a widespread view that allergy was the basis of most adverse reactions to food, but it is becoming increasingly clear that other, as yet poorly understood, mechanisms are responsible in the overwhelming majority of cases. This, together with the proliferation of popular literature on "food allergy" has resulted in considerable confusion in the minds of both the public and the medical profession on the subject.

Food Allergy a Constant Concern to the Medical World and Healthcare Providers: Practical Aspects
Life
Food allergy (FA) is a condition with a growing incidence and is a constant concern for the medical world and healthcare providers. With potential symptoms including anaphylaxis, in the event of an allergic reaction the patient’s life may well be endangered. The diagnosis of FA is a continuous challenge because mild cases tend to be ignored or diagnosed late and young children with allergies are cared for by parents, who are not always able to accurately interpret symptoms. It is very important to be able to differentiate FAs from food intolerance and toxic reactions to food. An accurate diagnosis is required to provide personalized management of an FA. More sophisticated and accurate diagnostic tests, including component diagnosis and epitope reactivity, allow the provision of a directed diagnosis, a more accurate therapeutic approach, and a useful prognostic evaluation. Tests used in current practice include the specific search for serum IgE, elimination diets, oral food challenge...

Food allergy is understood as all the adverse reactions to food products triggered by the immunological mechanism. The immunological reactions include the mediated IgE mechanisms and non-Ig-E mechanisms. It is estimated that the frequency of food allergies in general population is of 3.5-4% and usually come out in patients showing also other atopic disorders. The gastro-intestinal barrier is made up of epithelial cells, mucin cells (IgA secreting), proteolytic enzymes and billiary salts. The factors influencing the digestive tolerance are classified in antigenic factors and factors related to the host. The most important food products determining the most of allergies during childhood are: milk, eggs, nuts, flour and soya. The clinical manifestations in food allergies are the anaphylactic reaction, respiratory, cutaneous and digestive manifestations. The paraclinical diagnosis is different depending on the mediated immunologic mechanism, and the exclusion of the involved allergen is...
