Once upon a time, the milk came in three options: whole, low fat and weak. Maybe chocolate, if you were lucky.
Now, there are so many types of milk that there are bad morning cereals-you are: walnut milk, flax milk, oat milk, goat milk. A less known variety you may encounter in the food store is A2 milk.
What is A2 milk?
A2 milk is cow’s milk that contains mainly A2 beta-kazeine, which is clear that your body is digested and absorbed. It is different from most cow’s milk available in the United States, which contains a mixture of A2 beta-saasein and A1 beta-caasein.
For the first time popularly popular with New Zealand A2 Milk, A2 Milk was first sold in 2003 and has now grown in a $ 2 billion industry.
According to the company, A2 Milk can be found in more than 29,000 retail sellers across the SH.BA, including large boxes like Costco and Walmart. Like regular milk, A2 is available in all reduced and weak fat varieties.
Milk a1 vs a2 milk
A2 milk manufacturers claim that A1 beta-carail is difficult for some people to digest and can interfere with maintaining healthy blood sugar levels. (The research is scarce for both claims; more about it in a second.)
Casein is the largest protein set in milk, which includes about 82 percent of its overall protein content. The remaining 18 percent is the most popular whey protein. There are 13 different types of casein; A1 and A2 are the most common.
How is A2 milk, and what makes it different?
Milk A2 is produced by cows that possess a genetic variation that gives milk containing A2 beta-carail and lacks A1 beta-kazeine. Cows that produce milk containing A2 beta-carail are mainly found in Asia, Africa and parts of southern Europe. Milk from cows in the western world usually contains A1 beta-saasein.
The supposed benefits of milk A2
So is there any milk A2 any benefit from regular milk? “It is difficult to answer this question, as most A2 milk studies have been funded by A2 milk company and the dairy industry, which have interested in demonstrating benefits,” says Dana Hunnes, PH.D., RD, MPH, senior dietician in Ronald Reagan Uc Medical Center.
These are some of the claims made about A2 milk:
1. It’e is easier for digestion
A study funded by A2 Milk Company found that A1 beta-canein requires some more people to digest, which can lead to indigestion, bloating and gas. A review of the 2019 research said it may be true, but human studies are limited and more needed.
However, in a study conducted by Purdue University, lactose intolerant participants showed fewer GI symptoms after consuming A2 milk compared to conventional cow’s milk.
2. Promotes healthier sugar in blood
According to the California Dairy Foundation, since the 1980s, some researchers have made unfounded claims that the milk containing A1 beta-thisine can contribute to unhealthy blood sugar levels and even compromised cardiovascular function.
Considered culprit: BCM-7, a chain of amino acid produced when A1 beta-caasein is wasted. The theory is that BCM-7 can cause disease in people with immune deficiencies. But there is no scientific evidence in people to support this.
Possible dairy risks A2
The risks associated with A2 milk are slightly different from those associated with most cow’s milk.
Lactose intolerance
A2 milk contains the same amount of lactose as regular cow’s milk. People who are diagnosed with lactose intolerance can suffer the same digestive disturbance when they drink any type of milk.
allergy
Because A2 milk is still cow’s milk, it can promote an allergic reaction in people who are allergic to cow’s milk.
