In most cases food allergy develops at kids on the first year of life. At this particular time the child gets acquainted with various food. The structure of microflora of the kid by this moment still is completely not created, and many large molecules of foodstuff, having got into a stomach of the baby, cannot just be digested.
Reasons and origins
By the time of birth of the kid most its bodies still is up to the end not created and stay in a stage of "ripening". So, production of enzymes in a GIT is reduced. It means that the pancreas of the child is not capable yet in necessary volume to produce such enzymes as trypsin (splits proteins), amylase (splits carbohydrates), a lipase (splits fats), and gastric juice contains small quantity protease (splits protein), etc.
Therefore many food to certain age are contraindicated to kids. Even fruit, cottage cheese and meat, dietary for an adult organism, are contraindicated to children of chest age. At hit in an organism of the kid of such products because of big degree of permeability mucous intestines food molecules quickly pass in blood vessels where begin to develop IgE antibodies.
Process of a sensitization — hypersensibility to certain macromolecules begins. It means that the organism of the child got acquainted molecules, developed to them antibodies, and at the following inclusion in food of the same product of an antibody will react, and allergic reaction will develop. Such food sensitization can sometimes begin from the first days of life of the child.
Mother's food
In the first days of life of the child it is necessary to pay huge attention to a food allowance of the nursing mother. During this period it is desirable to limit excessive consumption by the nursing mother of home-made cow's milk, strawberry, chocolate, oranges, nuts, red fish and cottage cheese. Early transfer of the newborn to the artificial or mixed feeding is very undesirable. But, if this process is inevitable, it is necessary to try to exclude from the child's diet not adapted children's mixes and whole cow's milk in the form of the main food product.
Manifestations of food allergy at the child
1. Allergic irritation of integuments (Quincke's edema, atopic dermatitis, strofulyus — a children's pochesukha, a small tortoiseshell).2. Gastrointestinal violations (nausea, vomiting, vomiting, meteorizm, lock, gripes, diarrhea).3. Respiratory manifestations (allergic rhinitis, bronchial asthma). To begin effective treatment, it is necessary to establish as soon as possible a cause of illness, i.e. to find products allergens. For this purpose the attending physician collects the allergologichesky anamnesis (learns whether relatives had allergy cases earlier), charges to mom to keep a diary of food where it is necessary to write down reaction of an organism to new products. For more exact definition of allergen it is necessary to carry out also skin tests.
