Why A2 Milk?
All proteins are long chains of amino acids. Beta casein is a chain 229 amino acids in length. Cows who produce this protein in their milk with a proline at number 67 are called A2 cows, and are the older breeds of cows (e.g. Jerseys, Asian and African cows).
But some 5,000 years ago, a mutation occurred in this proline amino acid, converting it to histidine. Cows that have this mutated beta casein are called A1 cows, and include breeds like Holstein.
So the theory goes that by drinking milk from A1 cows, which are the predominant cows used for dairy products in the Australia, you’re exposed to BCM-7, which has been linked to the following,, if you are more allergy prone, due to inability to break down histamine: :
- Neurological impairment, including autistic and schizophrenic changes
- Type 1 diabetes
- An impaired immune response
