Why Choose Milk from Sheep, Goats and Buffalo?
Not all milk is the same. A2 milk comes from cows that naturally produce milk containing only the A2 variant of the protein beta-casein. Conventional cow's milk often contains both A1 and A2.
A1 vs A2: Understanding the DifferenceA1 och A2 – vad är skillnaden?
Not all milk is the same. A2 milk comes from cows that naturally produce milk containing only the A2 variant of the protein beta-casein. Conventional cow’s milk often contains both A1 and A2.
Digestion and Individual ToleranceMatsmältning och individuell tolerans
The difference may seem small on paper, but it can be noticeable. When A1 beta-casein is broken down during digestion, it releases more of the peptide BCM-7 than A2 beta-casein does. Some studies have linked this to digestive discomfort, including bloating, gas and abdominal symptoms. Because A2 milk does not release BCM-7 in the same way, some people find it easier to tolerate. The research is not yet conclusive, but several studies suggest that A2 milk may be a useful alternative for people who experience digestive problems associated with milk.
Which animals produce milk containing mostly A2 beta-casein?
- Goats
- Sheep
- Buffalo
- Camels
- Yaks
- Donkeys
- Humans / breast milk
- Certain cattle breeds, such as Jersey, Guernsey and many Asian and African breeds
In cattle, the proportion of A2 beta-casein varies by breed and individual animal. Cow’s milk therefore needs to come from cows tested for A2 beta-casein before it can reliably be marketed as A2 milk. Milk from goats, sheep, buffalo, camels, yaks and donkeys is generally predominantly A2.
