Yes, goat milk is predominantly A2.
Understanding A2 Milk
The term "A2" refers to a specific type of beta-casein protein found in milk. Most cow's milk contains both A1 and A2 beta-casein proteins. However, some animals, like goats, primarily produce milk with only the A2 type.
Goat Milk Composition
As highlighted by the provided reference, goat milk is predominantly A2 beta-casein dominant. This means the majority of the beta-casein protein found in goat milk is of the A2 variety. While trace amounts of A1 casein might be present, they are usually negligible.
Benefits of A2 Milk
While research is ongoing, some individuals find A2 milk easier to digest than A1-containing milk. This is because the A1 beta-casein protein can break down into a peptide called beta-casomorphin-7 (BCM-7), which some believe can cause digestive discomfort in some people.
Key Takeaways:
- Goat milk primarily contains A2 beta-casein.
- This makes it a potentially more digestible option for those sensitive to A1 milk.
