Allergy to cow's milk is a well-studied form of food allergy. There are both immediate and delayed patterns of milk allergy. Immediate type allergy tends to be obvious and shows up on skin tests. Delayed patterns of milk allergy are not obvious, do not produce positive skin tests and tend to cause chronic disease that is seldom diagnosed. Cow's milk contains many proteins that are antigenic - they excite immune responses.

People of all ages with gastrointestinal tract disease may have difficulty digesting these proteins and may absorb them as antigens. Milk problems may be attributed to lactose intolerance and the milk-sugar enzyme, lactase, may be prescribed. Milk allergy is a protein problem and is not improved by changing the milk sugar - often the diagnosis of "lactose intolerance" is incomplete or wrong and symptoms persist with only lactose exclusion........click for more
