One study included 15 male and female test subjects with known high risk of heart disease. Major improvements have been observed among children who regularly consume A2 milk sourced from Guernsey cows due to its high A2 beta casein at 95%. The protein component in milk is made up of up to 80% casein (1). KEY POINT: A1 beta-casein is assumed to stimulate the development of type-1 diabetes in children. Both A1 and A2 are proteins in the casein family, which makes up about one-third of all the proteins in human milk, but about 80 per cent of the proteins in cow's milk. Prominent professor Bob Elliot from the University of Auckland claims that a switch to A2 milk can ultimately solve all problems that 1 in every 4 Americans have in relation to dairy consumption (4).

The entire basis of the supposed problem with A1 milk is its pesky histidine amino acid at position 67. On the other hand, infants with autism that were breastfed or those under Gluten-free, Casein-free or GFCF diet displayed more developmental improvements with no traces of BCM-7 in their bloodstream (14). Historically, cows produced milk that contained only the A2 form of beta-casein. By Karl Kruszelnicki for Great Moments in Science. Studies that support these claims reveal that apart from lactose, there are other milk components that bring about unwanted digestive problems. In one study involving 41 men and women, results revealed that drinking A1 milk may result in softer stools than A2 milk consumption in some test subjects.

My understanding is cows do not only produce one protein or the other, rather a different proportion of each eg 80℅ A2 20% A1, therefore the milk is going through yet another stage of processing to meet their marketing claims. The only difference between A1 and A2 is a difference in the 67th amino acid in the chain.

In New Zealand, where the a2 Corporation was founded, the government's food safety summary for A1 and A2 milk states: "Further research, especially involving human trials, is needed before it can be said with confidence that the A1/A2 composition of milk is important in human health.". It was also suggested by scientists that certain proteins present in milk may be the major suspects in some cases of milk intolerance. Please can you amend please by removing the incorrect “a1” label from the Jersey cow.

Melatonin and Alcohol Interactions: What Happens When You Mix Them? BCM7 (Beta-casomorphin-7), an opioid peptide in A1 beta-casein is produced as a result of the breaking off of histidine in the number 67 amino acid chain during digestion (9, 10).

They looked at milk and other dairy products containing A1 casein versus A2 casein. Warnings – A1 vs. A2 Milk! At this position, A1 has a histidine amino acid, while A2 has a proline amino acid. More studies should be implemented before any solid conclusions can be made to connect A1 milk consumption with SIDS. That one amino acid change means when the A1 protein is broken down, it can create the peptide BCM-7. According to the California Research Foundation (http://cdrf.org/2017/02/09/a2-milk-facts/) Jersey contain the A2 beta casein. The article clearly states the lack of connections made to health problems vs. A1.

Recently, a New Zealand company investigated the differences. Exploring casein —> think of this protein as a large family, consisting of several ‘types’ of relatives (different caseins), and each ‘relative’ has it’s own composition, genetic variation, and … Milk produced by A1 cows supposedly produces opiate-like effects resulting in the development of mild to serious medical conditions (2).

The crossover design of the study meant that participants consumed both A1 and A2 beta-casein at different periods of time (26, 27). Also lactose intolerance is to do with the carbohydrates in dairy not the protein! Professor Truswell found there was "no convincing or probable evidence" that the A1 beta-casein protein in cows' milk is a factor causing type 1 diabetes or heart disease. To the consumers willing to pay, or not pay, extra for milk, both are nutritious choices. This genetic testing makes A2 milk more expensive.
