A paradoxical life situation is when, instead of being a source of life, health and positive emotions, food brings obvious harm.

Unfortunately, this happens quite often..

The reasons for the harmful effects of food on the body are different..

Of the inadequate reactions of the human body to certain types of food and food products, the most common ones can be noted:.

1) allergic reactions to food.

Allergy - a change in the body's reactivity to repeated exposure to various stimuli - microbes, foreign proteins and chemical compounds, etc.. Allergy leads to the development of allergic diseases, decreased immunity;

2) pseudo-allergic reactions to food;

3) idiosyncrasy to certain foods;

4) migraine as a reaction to food.

The term " Pirquet (1874-1929). Allergy is currently understood in a simplified way to mean the state of the body arising from the interaction of antibodies - immunoglobulins E - and their corresponding antigens.

Under the influence of a complex of antigens - antibodies from the cells of the connective tissue, the so-called " , the presence of which in the tissues of the body explains the clinical manifestations of the symptoms of an allergic condition - itching of the skin, spasm (narrowing) of the blood vessels and bronchi, skin manifestations - rash, urticaria, etc.. , and more severe - anaphylactic shock.

An antigen, in principle, can be any substance, but more often it is protein compounds and polysaccharides. Food allergy is associated not only with diseases of the gastrointestinal tract, but also bronchial asthma (especially in children), rhinitis, conjunctivitis, stomatitis, eczema, arthritis, headache, etc..

Allergic reactions to food can be direct (vomiting, diarrhea), secondary (blood loss, iron and protein deficiency) and long-term (allergic rhinitis, serous otitis media, bronchial asthma, urticaria, eczema, Quincke's edema).
