Slowly Does It Food have recently started stocking A2 milk. Find out what it is and why you should be drinking it apart from the fact that it tastes great.
What is A2?
Dairy milk contains six main types of protein – four casein proteins and two whey proteins. The casein proteins comprise about 80% of milk and one of these includes beta casein. A1 and A2 are the two most common forms of the beta casein protein. Most milk in Australia contains a combination of these proteins.
A2 milk is high in A2 beta casein. This composition of milk is achieved by selecting cows that naturally produce milk high in the A2 protein. Particular breeds of cattle, such as Guernseys and Jerseys possess this trait. These cows are then milked to produce A2 milk.
Why A2 milk?
There have been recent studies to suggest that A1 beta casein found in milk is linked to type 1 diabetes, heart disease, schizophrenia and autism. The strongest evidence comes from a population study comparing the type of milk consumed in 20 countries and rates of type 1 diabetes and heart disease. In line with this evidence is support for A2 milk, which is free of the A1 protein. A2 Dairy Products, producers of a2 MilkTM, also claim its products offer “natural intolerance protection”.
