Therefore, further investigations are needed. On the basis of the available results, we cannot conclusively assess the health effects of A1milk and A2-milk. In conclusion, the effects of A1-milk compared to A2-milk on human health show mixed results. For this reason, there is a growing global interest in A2-milk. Subsequently increase inflammation, Type-1-diabetes, heart disease, autism, gastrointestinal discomfort and other disease in the consumer. These studies are based on digestion of A1milk which lead to release β-casomorphin-7 (BCM-7). Several studies have reported that cow’s milk with a dominant or singular A2-milk may be healthier than A1-milk. At this position, A2-milk has a proline amino acid, while A1-milk has histidine amino acid. The only difference between A1- and A2-milk is a difference in the 67th amino acid in the chain. A1 and A2 are the most common variants, which are called A1 β-casein (A1-milk) and A2 β-casein (A2-milk). However, there are thirteen genetic variants of β-casein found in cow´s milk. Within β-casein, there are a number of variants which are genetically determined. β-casein is an important part of the caseins, which makes up about 37% of the total caseins. Caseins constitute about 80% of the total proteins of cow’s milk. They occur as caseins, whey proteins, enzymes, minor proteins and nitrogen compounds.

Milk proteins are a heterogeneous group of polymeric compounds that have a wide range of different molecular structures and properties.

Mellitus, autoimmune and cardiovascular diseases and other illness such as autism and schizophrenia areĪlso reported. Strong correlation between consumption of BCM7 containing A1 milk. BCM7 is implicated in digestive, immune and brain development changes and A1 but not A2 β-casein liberates the β-casomorphin-7 (BCM7), A1 and A2 milk variants differ by a single amino acid, resulting in differential secondary Genetic variants of beta-casein, the problematic type of casein protein found in milk is the A1 beta casein,ĭevil in the milk. Of β-casein (~30% of cows’ milk-proteins) are genetically determined A1, A2, A3, B, C etc. However, casein free diet is recommended for infants with immunological sensitivities. Milk is the highly evolved secretion of mammary glands of mammals and the most perfect food for infants.
