Guide To Milk Allergy Symptoms

A milk allergy occurs when the immune system rejects the proteins found in animal milk. Most individuals who have a milk allergy are allergic to cow milk, which contains alpha S1-casein protein. Between two and three percent of children younger than three years old have a milk allergy and eighty percent of these children will generally outgrow the allergy by the time they become adults. Milk allergy is also often times mistakenly believed to be lactose intolerance, which is when the body is unable to digest the lactose found in dairy products. While milk allergy and lactose intolerance share many of the same symptoms, a milk allergy can be fatal.
