Milk allergy currently is quite widespread phenomenon, both among adults and among children. This disease can be determined as human body intolerance of milk protein – casein. Some people feel unpleasant symptoms of disease after use of cow’s milk only while the goat and sheep is tolerantly accepted by them, other people have an allergic reaction absolutely to all dairy products.
It is proved by numerous researches in the field of pediatrics that allergy to milk is provoked by early introduction to a child ration different baby formulas on the basis of cow’s milk. It is explained by that fact that receiving milk protein, gastrointestinal tract of the child having not been formed yet activates a protective reaction of the immune system. Disability to split larger molecules of casein completely leads to identification by their organism of the child as some foreign elements. As result, there are implications of various allergy symptoms. Some children, however, have allergic reaction to milk from the first days of life. There is an absolutely small percent of babies suffering from allergy to maternal milk.
Adults often have allergy to all types of milk because of organism intolerance of lactose or milk sugar. There is a special enzyme in human intestine – lactase, – which splits lactose on other components. At insufficient amount of the specified enzyme the person also has an allergic reaction.
It is categorically undesirable to the people having milk allergy to use milk of animal origin. Vegetable milk (for example, soy milk) can only be used as a substitute which does not cause allergy reaction.
