If you have trouble digesting milk but have had no success with lactose-free varieties, a relatively new milk that's supposed to be “easier on digestion” may have caught your eye. There are good reasons to include milk in your diet. It packs a powerful nutritional punch, providing protein and fat as well as many key vitamins and minerals. However some people do not produce enough of an enzyme called lactase, which digests lactose in the small intestine, which can cause abdominal pain, bloating, diarrhea, and gas. Lactose intolerance is often blamed for these symptoms. Lactose-free milk, such as Lactaid, has lactase added to predigest the lactose. However the addition of lactase can make milk taste funny or sweeter, which is off-putting. That is where A2 Milk comes in. Milk contain several types of casein, an amino acid which gives milk it protein power. Beta-casein is the second most prevalent form of this protein and the two most common forms are A1 beta-casein and A2 beta-casein. Regular milk contains both A1 and A2 beta-casein, but A2 milk contains only A2 beta-casein (naturally produced from bovine breeds that originated in the Channel Islands and southern France). Some studies suggest that the A1 protein is associated with digestive discomfort in some people, which is why A2 Milk may be the happy ground between regular milk and lactose-free varieties. While the research is scarce, lactose intolerant people should be able to tell if A2 Milk's claims are true or not by trying it out. However if you don’t have problems digesting milk, though, there’s no reason to pay the premium price for a2 milk or Lactaid.
