Drinking cow's milk is always a hotly debated food debate – should you be skinny or full-bodied, or should you not drink it at all and switch to non-dairy milk?
Regardless of the dairy team you work for, it's no surprise that cow's milk and dairy products generally cause stomach discomfort for some people who have difficulty digesting them, which is why many switch to herbal alternatives (FYI, if You still do not know if you have a milk allergy or just an intolerance, here's the difference.)
But a2 Milk, which was developed to solve this problem, falls into a strange intermediate category. The dairy option is marketed as "1
Here's what a2 Milk really is – and whether you should make the switch or not  What is a2 milk?
First, the basics: Cow milk consists of two milk proteins – whey and casein – There are 12 different types of casein proteins, and the most common are A1 and A2.
"A1 and A2 are the ones in The milk naturally occurring beta-casein proteins, "says Vandana Sheth, a registered nutritionist and spokesman for the Academy of Nutrition and Dietetics." Normal cow's milk contains a combination of A1 and A2. Although the difference between A1 and A2 is small, the difference plays an important role in the digestion of the protein, "says Sheth.
This is because when A1 protein is broken down, a protein fragment called beta-casomorphin-7 ( BCM-7), which is thought to cause digestive problems in the milk, does not produce BCM-7 if A2 milk is broken.
Milk tastes just like the ordinary old milk you drank However, contains only the A2 protein Reduce stomach discomfort in some people, explains Sheth. And this is the biggest argument of a2 Milk.
A study published in 2017 Nutrition Journal found out in that participants taking lactose-intolerant milk containing only A2-beta-casein protein had fewer gastrointestinal tract symptoms (such as bloating, flatulence and abdominal pain) in comparison to normal milk, which supports the notion that it may be easier to digest than normal milk.
Where did a2 Milk Start?
Even though you may have only seen commercials for the drug recently, a2 Milk is on the market in Australia.
According to Quartz, everything started in the 1990s when New Zealand-based scientist and entrepreneur Corran McLachlan discovered the A1 and A2 proteins in cow's milk. He found that many people who have milk drinking symptoms have difficulty digesting the A1 protein. He created a2 so that milk lovers will not have to compromise on taste or nutrition when switching to a herbal or lactose free option.
Is a2 milk lactose free?
One big point for clarification: a2 milk contains the same amount of lactose as ordinary cow's milk. While a2 milk can help people with milk sensitivity or milk protein intolerance, it is not suitable for people who have specific lactose intolerance.
For your information, lactose intolerance is the difficulty of lactose, the natural sugar, to digest enzyme lactase, which is needed for the digestion of lactose. The digestive disorder is genetic and affects 30 to 50 million Americans. According to Mayo Clinic, she also occurs more often in people of African, Asian and Hispanic descent.
Although a2 milk has proven beneficial for people with lactose intolerance, little has been done because of limited research. It is not enough to use a2 milk as a verified beverage for people with lactose intolerance. So if you have cow's milk or lactose allergy or lactose intolerance, stay away from it.
Should you try a2 milk?
Conclusion: There is really nothing to lose. "A2 Milk is (still) cow's milk and offers the same nutritional profile and benefits as regular cow's milk, with easier digestion for some people who find it harder to digest normal milk," says Sheth. (For information, here's a handy diagram that lets you choose from 13 different milks.)
Oh yeah, and ICYMI, cow's milk provides tons of nutrients that many milk alternatives do not offer. So if you only drink oatmeal or almond milk to avoid stomach upset (and are not really lactose intolerant), consider switching to good old cow's milk for calcium, vitamin D, phosphorus, potassium, and protein.
