Just like the A2 cows we milk for our ‘tummy friendly’ ice cream, human breast milk is also A2 milk. The A2 protein is natural to the body and can be easily digested, so it’s safe for mothers to feed their babies. Most cow’s milk today now contains the mutated A1 protein gene along with the A2 protein gene. The mutated A1 protein gene is not easily digested by the human body.
The A2 protein chain is easily digested by the body because it safely adheres to the main amino acid chain whereas the A1 protein floats freely by itself making it much more difficult for the body to digest. Milk proteins need to attach to the main amino acid chain for the body to more easily digest them.
