The latest (exaggerated) promise of the food industry: A2 milk yogurts

Source Summary

Buying yogurt should be a simpler task than it has become. If we have a clear taste (Let's take it step by step. To begin with, what does A1 and A2 milk mean. “Some cow breeds produce a type of milk protein, beta-casein A2, while many other European breeds produce beta-casein A1,” says dietitian-nutritionist Anna Costa. In so-called A2 milk, this protein is mostly present, while in other milks it is not. “We know that the digestion of milk containing A1 can generate a peptide called BCM-7 (a peptide is a short chain of amino acids linked together), which some studies have linked to digestive discomfort in sensitive individuals,” points out Anna Grífols. Therefore, since the industry knows that A2 milks are more digestible, what is being done is selecting cows, which are usually Friesians, that produce beta-casein A2.
