How do you know if you have Casein Intolerance?

Infants usually grow out of their casein intolerance, though sometimes it can persist into adulthood. If your casein intolerance was not diagnosed as a child it can sometimes only be late adulthood when it is recognised correctly as casein intolerance.  But, the normally symptoms are indicative in young babies when they are first given milk and so few are left undiagnosed.

Diagnosing milk protein intolerance

There is no single diagnostic test that can be used to identify milk protein intolerance. An elimination and challenge diet is the most reliable identification method for food intolerance. You seek medical advice before starting an elimination diet. It is important to find substitutes for the foods you will be eliminating.   During the elimination diet you should avoid all foods that contain the casein protein. If symptoms improve casein is most probably the offending food. To test this theory, you should try to eat a small amount of food with milk protein in and see if symptoms are triggered. If symptoms present, casein intolerance is the most likely explanation.
