Even benign food can be poisonous if you are allergic to a particular product or even to one of its ingredients From the depths of time Do not think that a food allergy is the heritage of the present. Of course, today more people suffer from an inadequate response to food products than in the old days. This is largely to blame for bad ecology, as well as preservatives and chemicals, which are crammed with most tempting delicacies. However, perverse reactions to food have been known since antiquity. Thus, Hippocrates first described the episode of intolerance to cow's milk, and Galen - a case of hypersensitivity to goat milk.

Then, the list of "unreliable" included fish and eggs. Further - more, they were joined by legumes, cereals, fruits. Well, today, as doctors say, there simply is not a product for which a person could not have an allergy. Nevertheless, the most common food allergens are well known. From products of animal origin - this is cow and goat milk, chicken eggs, fish and seafood, from plant foods - legumes and nuts, from cereals - wheat, rye, barley and corn, and from fruits and vegetables - all red and orange fruits.

To clarify the diagnosis of skin tests. For this, drops of 10-15 most common allergens are applied to the inner surface of the elbow. Then, with a thin feather, the doctor guides the patient with a small scratch in this place. After a couple of minutes, the skin reaction is evaluated. For intradermal tests, a deeper incision is made. This method is used if the allergy is not clearly expressed. All allergic tests should be done only under the supervision of a doctor.

A more informative way of diagnosis is a blood test from a vein.

Such an analysis is considered not only the most reliable, but also the only possible in cases where the doctor is not sure how much a strong allergic reaction can be expected from the patient during the carrying out of skin tests. In addition, only this method can be performed with psoriasis and eczema. Also, allergists usually prescribe an analysis to determine antibodies to food allergens in the blood serum. Additional methods for investigating food allergens include: gastroscopy with small intestine biopsy, assessment of the permeability of the intestinal mucosa, and some other nedug methods. en.
