What Is Milk Allergy?
Cow’s milk allergy is the most common food allergy in infants and young children. Even though most children eventually outgrow their allergy to milk, milk allergy is also among the most common food allergies in adults. Young children who are allergic to fresh milk but can eat baked milk without reacting may be more likely to outgrow their milk allergy at an earlier age than young children who react to baked milk.
When a person with a milk allergy is exposed to milk, proteins in the milk bind to IgE antibodies made by the person’s immune system. This triggers the person’s immune defenses, leading to reaction symptoms that can be mild or very severe.
About 2.5 percent of children under three years old are allergic to milk.
