Does goat milk contain casein or whey?
Casein is a natural protein found in all milk. Some people have an intolerance or allergy to casein—especially alpha s1 casein, which occurs in high levels in most cow milk. Goat milk is generally lower in alpha S1 casein and often contains a higher percentage of alpha s2 casein, depending on the breed.2 Casein comprises 70-80% of the proteins in goat milk; whey proteins account for the other 20-30%. Whey contains many of the important nutrients in yogurt and kefir that aid in muscle development and support the body’s immune response.2
If you have been diagnosed with a milk protein allergy, goat milk may not be right for you. It is important that you consult your physician or health provider before making any dietary changes.
