A recently granted patent (Publication Number: US11911439B2) discloses a method for treating irritable bowel syndrome in adult humans who consume bovine milk or bovine milk products containing beta-casein A1 and beta-casein A2. The method involves replacing the bovine milk or milk product in their diet with a version that does not contain beta-casein A1, specifically targeting cases where irritable bowel syndrome is induced by beta-casomorphin-7 (BCM-7) exclusively.

The patent further specifies that the milk used in the method can be in various forms such as fresh milk, milk powder, liquid milk reconstituted from powder, skim milk, homogenised milk, condensed milk, evaporated milk, pasteurised milk, non-pasteurised milk, or UHT milk. Additionally, the method extends to milk products like cream, yoghurt, quark, cheese, butter, or ice cream.
