2023年7月17日 · Currently, A2 milk is marketed as a healthier choice than regular A1 milk. Proponents assert that A2 has several health benefits and is easier for people with milk intolerance to digest. This...

2023年7月11日 · This MNT Knowledge Center article looks at the truth about A2 milk, a new milk on the market that is supposedly healthier and easy to digest. MNT examines the research and the risks.

2021年11月30日 · A1 milk has a histidine amino acid, whereas A2 milk has a proline amino acid. Why does this matter? Well, when A1 milk breaks down during digestion, it creates the peptide BCM-7. Peptides can impact our blood pressure, immune system, and even how our blood clots. It also can cause what some people like to call “intestinal discomfort.”

2019年4月21日 · Epidemiological evidence has indicated that consumption of milk containing the A1 variant is linked to increased risk of developing cardiovascular disease, type 1 diabetes, sudden infant death syndrome, autism and schizophrenia.

2018年6月18日 · The evidence for A1 beta-casein proteins in milk causing autism and schizophrenia "is more speculative" and "more unsubstantial" than that for type 1 diabetes and heart disease, he reported.

2020年3月10日 · While the sugar has been fingered for the blame, some researchers claim it’s really a protein known as A1. Here’s where things get a little complicated: Beta-casein is one of the main proteins in milk, but it comes in two varieties: A1 and A2. While most cows’ milk contains both, some types have just A2.

A2 milk is free of the A1 protein and has the same nutrient profile as conventional cow’s milk, and fortified soymilk is recommended by the 2020–2025 Dietary Guidelines for Americans as an appropriate dairy substitute, making both nutritious choices.

2021年7月7日 · With high lactose intolerance, A1 milk type has carbohydrates and fats which encourages the growth of unhealthy bacteria in the human intestine which lowers the immunity in children.

Dr. Macrina: “ Due to differing genetics, cows produce milk with A1 or A2 or a combination of both. A1 and A2 each have 209 amino acids and differ by only one. A1 has histidine at position 67, while A2 has proline. This makes A1 susceptible to splitting apart during digestion.

A1 vs A2 milk. A1-beta casein is associated with increased gastrointestinal inflammation, constipation, and decreased cognitive processing speed and accuracy compared to those receiving A2 beta casein milk.
