That is 50% each year, but never seems to pencil out to being one in two animals ;). 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). I appreciated the reporting, found it interesting, but am amused at the bias in the comment section and questionnaire response. A1 milk has A1 type of protein (casein) and A2 milk has A2 type of protein (casein).

A2 milk is milk from mother dairy cows that have been bred to not produce the A1 beta-casein protein—a form of the casein protein in milk. The makers of A2 milk contend that lactose is not the real suspect for the development of lactose intolerance, but a mutation caused by A1 beta-casein, a compound found in store-brought milk and dairy products. 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 … Sleep apnea has been linked to an increased incidence of SIDS (15).

In 2005, independent researcher Stewart Truswell carried out a comprehensive investigation of the A1 and A2 proteins. At this position, A1 has a histidine amino acid, while A2 has a proline amino acid. The A1 and A2 variants of beta casein differ at amino acid position 67 with histidine in A1 and proline in A2 milk as a result of single nucleotide difference [2]. The experiment on rabbits clearly showed that the accumulation of fats may potentially clog and block blood vessels that may result in heart disease. Milk has several types of casein and beta casein is the second most common type casein in cow’s milk. KEY POINT: The difference between A1 and A2 is in the amino acid chain number 67.
