Best Milk for Infants: A1 or A2

1,022

Enough of the hubbub regarding A1 or A2 milk quality. The argument behind this health battle is still on. To simplify this hustle of superiority, this blog is especially written for all Agog Mothers who want to know the right type of milk for their babies. Read to know all about the type of A1 and A2 before giving an ear to others.  

What is type A1 & A2?

A1 and A2 casein are genetic variants of the beta-casein milk protein that differ by one amino acid in their structure. A2 milk is produced from cows that naturally only contain the A2 protein. Human breast milk, goat and sheep’s milk, and certain varieties of cow’s milk contain the A2 beta casein.

How you get A2 Milk?

In regular milk production, all the cow’s milks are typically blended together, so you get a mix of proteins in the milk packet. To get A2 milk, a simple genetic test is used to determine which cows make only that protein variation, and their milk is used exclusively. During the breakdown of A1 in the gut, a peptide fragment (a chain of amino acids) called BCM-7 is formed. This fragment can slow down digestion, trigger inflammation and cause symptoms such as bloating, gas, abdominal pain, diarrhoea in infant. No such fragment is formed with A2 digestion.

What health complications are attributed to the consumption of A1 milk? 

Allergies, asthma, autism, eczema, GI distress and IBS symptoms, autoimmune conditions, and schizophrenia are the most common complaints/ syndrome that Mothers comes for their babies to Doctor.It’s also been observed that those with leaky gut are more susceptible to potential harm from A1 milk.

What is the difference between composition of A1 and A2 milk?

A1 beta-casein comes from the most common cow breed that originated in Australia, United States, and Northern Europe. Species are Holstein, Friesian, and Ayrshire. A1 beta-casein can be found on all commercially-prepared milk.

A2 beta-casein is protein found in milk produced by cows like the Jersey, Charolais, Guernsey, and Limousin. Milk produced by other mammals such as those from human, goat, and sheep is similar to A2 dairy milk mainly due to the presence of proline in it.

How A2 milk supports digestion?

Proline is strongly bonded with a small protein called BCM 7, which prevents it from getting into the milk produced by A2 cows. While, Histidine holds a weak bond with BCM 7, so it is easily released in the GI tract of animals and can enter the human body on consumption of milk from A1 cows and interact with the digestive system and internal organ.

Rethink about milk selection 

Some studies indicate that A1 beta-casein may be harmful, and that A2 beta-casein is a safer choice in terms of better digestion in the gut. But, we cannot make it the benchmark to choose the milk for babies. Your treating Doctor and Nutritionist will advise you better. Do not copy others or the market brands of milk. Remember every infant has a different body metabolism.

Do you also Know :
75% of cows in the world are A1. Asia and Africa have mostly A2 type of Milk.
BCM7 found in A1 milk is the reason why regular cow’s milk is considered to be a less healthy option than milk containing A2 beta-casein. BCM7 can cause problems within the gut leading to IBS type symptoms.
Scientists at Curtin University in Perth found that people reported less abdominal pain and bloating after drinking A2 milk than A1
