A1 vs A2 Milk

What is A1 and A2 Milk?

More than 95% of cow milk proteins consist of caseins and whey proteins, with beta casein being the second most abundant. In A1 and A2 milk, there's a tiny difference at position 67 in a protein called beta casein. In A1 milk, there's a histidine amino acid at that spot, while in A2 milk, it's a proline amino acid. This genetic polymorphism results in a conformational change in the secondary structure of expressed β-casein protein.

The A1 and A2 Hypothesis

Research suggests that the gastrointestinal proteolytic digestion of A1 variant beta-casein, found in both raw and processed milk, leads to the generation of bioactive peptide, beta casomorphin 7 (BCM7). Infants, with immature gastrointestinal tracts, may absorb BCM-7 more readily, while adults may experience biological activity locally on the intestinal brush border. Studies indicate that A1 milk consumption may be associated with health risks, including type-1 diabetes, coronary heart disease, arteriosclerosis, sudden infant death syndrome, autism, and schizophrenia

Scientifically Proven Health Benefits of A2 Milk

Contrary to A1 milk, A2 milk has emerged as a potential healthier choice. Populations consuming milk high in A2 beta-casein variants show a lower incidence of cardiovascular disease and type-1 diabetes. The A2 hypothesis, though requiring further research, has garnered attention for its intriguing potential impact on public health.

A2 Milk Composition

A2 milk, derived from indigenous cows and buffalo, exclusively contains the A2 beta-casein allele. This composition makes it a source of safe milk, with no presence of the potentially problematic A1 allele.

A2 Milk Health Benefits for Women, Elders, and Children

Women's Health

A2 milk has been linked to benefits for women, providing essential nutrients for bone health, including calcium, phosphorus, and vitamin D. Additionally, the absence of A1 beta-casein may contribute to reduced inflammation, supporting overall well-being.

Elderly Nutrition

A2 milk, rich in amino acids and easily digestible proteins, can be a valuable nutritional source for the elderly. Improved digestibility may alleviate digestive discomfort commonly associated with age.

Children's Development

A2 milk's potential to reduce the risk of health issues associated with A1 milk makes it a preferable choice for children's development. The nutrient-rich profile supports optimal growth and development.

Can A2 Milk Help Cure Diseases?

While research is ongoing, preliminary evidence suggests that A2 milk may contribute to a lower incidence of certain diseases compared to A1 milk. The reduction in autistic and schizophrenic symptoms observed with decreased A1 milk intake is an encouraging sign, emphasizing the need for further exploration into the potential health benefits of A2 milk consumption.
