Goat milk is often presented as the solution for people with a cow milk protein allergy. Unfortunately this is often not the case.
Whether goat milk can be tolerated better than cow milk will depend on the specific protein involved in the allergy. Most people with a cow milk protein allergy are allergic to b-lactoglobulin. However this protein is also present in goat milk; consequently goat milk does not offer these people an alternative.
It is worthwhile trying goat milk as an alternative for cow milk, in consultation with your doctor or dietist, provided that the allergic symptoms are not life threatening, and the person involved is above 1 year of age. This will add an important source of proteins and calcium to the diet.
