Not all milk proteins are created equal. Over time, things change. Did you know the original beta casein protein in milk was the A2 protein? Yes! Thousands of years ago cows - like the native breed of cows in India (known as Desi Cows) - produced milk exclusively containing this type of casein protein. It was about 5,000 years ago, a natural mutation occurred creating a new variant known as A1 protein.
Today, cows produce both A1 and/or A2 protein in their milk. Approximately one third of cows produce only A1 casein protein, one third of cows produce only A2 casein protein and the remainder of cows are a mix of A1 and A2. a2 Milk™ is a naturally occurring cows’ milk and we don't do anything to the cows to get A1 free milk - we just choose cows that only produce the A2 protein. Which protein they produce is a result of genetics, just like having brown eyes versus blue eyes. Although there are some breeds of cows that may have a higher percentage of A2 only, they still need to be tested to confirm they are A1 free. Neat, right?
Why is the original protein best?
So why is A2 protein the better protein? And why should you choose milk that only contains A2 protein? Published research has found this type of milk is naturally easier on digestion and may help avoid discomfort in some people and has the same nutrition and creamy, delicious flavor as regular dairy milk. When you choose this type of milk, you may experience less tummy discomfort. Sticking to milk that contains only the A2 protein can make all the difference in having a great start to your day!
In some places, like India, the highest-milking indigenous breeds (desi cows) are 100% A2 protein and as such, 98% of milk sold in the region contains the A2 protein, no A1. Conversely, in Canada most milk found in grocery stores contains A1 protein so those who have lived in India and surrounding countries may feel a difference when drinking regular milk here. In situations like this, choosing a2 Milk™ that contains only the A2 protein and no A1, may be easier on digestion and help avoid discomfort. Luckily, you can find a2 Milk™ throughout Canada!
The science behind the benefits
If your healthcare professional hasn't diagnosed you with lactose intolerance, your digestion issues may be related to the proteins you're consuming in your current milk products. Focusing on milk containing only the A2 casein protein may help; a recent clinical study conducted by Dr. Dennis Savaiano, Professor of Nutrition at Indiana’s Purdue University Meredith, indicates that some people who suffer stomach discomfort after drinking conventional milk may have significantly reduced symptoms if they consume milk that contains only the A2 beta casein protein type and is A1 protein free.
So if you want the very best for your family and yourself, choose a2 Milk™ containing the original, better protein. You can find a2 Milk™ at your local grocer in the dairy case. Happier digestion is just a sip away!
