These symptoms did not occur after they consumed the A2 milk.Some researchers hypothesized that consuming A1 protein was associated with a higher risk for A2 milk still contains lactose and milk protein, so it is not appropriate for people with lactose intolerance, galactosemia, or a milk allergy.Furthermore, some people choose not to consume dairy and to follow a vegan diet, the Paleo diet, or to try to reduce There are many non-dairy milk alternatives available for purchase in health food stores or online.
The two major proteins in milk are casein and whey.Casein accounts for about 80 percent of the protein in milk. This product, called A2 milk, has garnered attention from both consumers and scientists.Supporters of A2 milk claim that it is easier to digest and absorb than other types of milk. About 30 to 35 percent of the casein (equivalent to two teaspoons per quart of milk) is beta-casein, of which there are several varieties, determined by the genes of the cow. A2 milk is a variety of cows' milk that mostly lacks a form of β-casein proteins called A1, and instead has mostly the A2 form. A1 and A2 are two variants of beta-casein.Historically, cows produced milk that contained only the A2 form of beta-casein.

The sole difference is that one of the 209 amino acids that make up the beta-casein proteins, a Scientists believe the difference originated as a mutation that occurred between 5000 and 10,000 years ago—as cattle were being taken north into Europe—when the proline at position 67 was replaced by histidine, with the mutation subsequently spreading widely throughout herds in the Western world through breeding.The percentage of the A1 and A2 beta-casein protein varies between herds of cattle, and also between countries and provinces.
