Cow milk

Allergy to cow milk (Bos domesticus) is an allergy caused by milk proteins: casein, lactoglobulin and lactalbumin. It is one of the most common food allergies worldwide in infants and preschool children. It is estimated that between 6-8% of one-year-old children have some type of food allergy, and cow milk protein allergy (CMPA) is the main cause. In some countries it has increased in recent years, reaching a prevalence of 10% and an increase in anaphylactic reactions. Cow milk is the most common cause of allergy, but milk from other mammals can also cause an allergic reaction. In most cases, the allergy disappears with age. Milk allergy differs from milk protein or lactose intolerance, since in these cases the immune system is not involved, so it requires a different treatment. Symptoms range from mild to severe, and can cause wheezing, vomiting, hives, and digestive problems. This allergy can cause anaphylaxis, and therefore be life-threatening. As a prevention it is recommended to avoid milk and products derived from it.
