Once upon a time, the milk arrived in three options: whole, low in fat and careless. Maybe chocolate, if you had luck.
Now, there are so many Milk varieties As there are bad breakfast cereals: walnut milks, linen milk, oat milkgoat milk A less known variety that can be found in the groceries is milk A2.
What is milk A2?
A2 milk is cow’s milk that contains predominantly beta-casein A2, which is supposedly easier for your body digest and absorb. It is different from the majority of the cow’s milk available in the United States, which contains a mixture of Beta-Caseine A2 and Beta-Caseína A1.
Popularized for the first time by New Zealand based in New Zealand The A2 milk companyA2 milk was sold for the first time in 2003 and has now become a $ 2 billion industry.
According to the company, A2 milk can be found in More than 29,000 retailers Throughout the United States, including Big-Box stores such as Costco and Walmart. Like regular milk, A2 is available in entire varieties, reduced fat and skim.
Milk A1 vs. A2 milk
A2 Milk manufacturers claim that beta-caseine A1 is difficult for some people to digest and can interfere with the maintenance of healthy blood sugar levels. (The investigation is scarce in both statements; more about that in a second).
Casein is the largest protein group in milk, which includes 82 percent of its total protein content. The remaining 18 percent is the most commonly known serum protein. There is 13 different types of casein; A1 and A2 are the most common.
How is Milk A2 and what makes it different?
A2 milk is produced by cows that has a genetic variation that produces milk that contains beta-caseine A2 and lacks beta-casein A1. The cows that produce milk that contain beta-casein A2 are mainly found in Asia, Africa and part of southern Europe. Cow’s milk in the western world generally contains beta-case A1.
Supposed benefits of milk A2
So, does A2 milk have any benefit on regular milk? «It is difficult to answer that question, since most studies on milk A2 have been funded by the A2 milk industry and the dairy industry, which have interests acquired in the demonstration of benefits,» he says Dana HunnesPh.D., RD, MPH, senior dietitist at the Ronald Reagan UCLA Medical Center.
These are some of the statements that have been made about milk A2:
1. is easier in digestion
TO study Financed by A2 Milk Company discovered that A1 Beta-Casein takes some people more time to digest, which can lead to indigestion, swelling and gas. TO 2019 research review He said it may be true, but humans are limited and more are needed.
However, in A study Performed by the University of Purdue, lactose -into -conolerant participants showed less GI symptoms after consuming A2 milk compared to conventional cow’s milk.
2. Promote the healthiest blood sugar level
According to him California Milkish Research FoundationSince the 1980s, some researchers have made unfounded statements that the milk containing beta-casein A1 can contribute to the non-healthy levels of blood sugar and even compromised cardiovascular function.
The alleged culprit: BCM-7, a amino acid chain that occurs when beta-casein is digested. The theory is that BCM-7 can cause diseases in people with immune deficiencies. But there is no scientific evidence in humans to support this.
Possible Milk Risks A2
The risks associated with milk A2 are little different from those associated with the majority of cow’s milk.
Lactose intolerance
A2 milk contains the same amount of lactose as regular cow’s milk. People who have been diagnosed with lactose intolerance can suffer the same digestive discomfort when drinking any type of milk.
Allergies
Because A2 milk is still cow’s milk, it can cause an allergic reaction in allergic people to cow’s milk.
