In his book “The Longevity Paradox” Dr. Steven Gundry has interesting information regarding cow’s milk and explaining that a couple of thousand years ago, northern European cows suffered a mutation in their milk protein from casein A2 to casein A1. Why is this important? Because casein A1 can turn into an opioid peptide called beta-casomorphin-7 that when digested, attaches to the pancreas insulin producing cells, triggering an immune response and inflammation.
Scientists are now suspecting that this is the likely primary cause of diabetes type 1. Normally, our physiological defense response would be gastrointestinal discomfort and overproduction of mucus that is wrongly attributed to the cow’s milk sugar lactose, but in most cases, the culprit is the casein A1.
OK, this is very interesting, but where do we go from here? The best solution is to stay away from regular cow’s milk, especially infants, since it is not only loaded with casein A1 but also antibiotics and insulin like growth factor 1 or IGF-1 to make cows develop quickly. All this affect your friendly gut bacteria, generating a series of problems including inflammation. However, if you choose to enjoy dairy products, try to consume goat, sheep or buffalo milk products that contain the healthier casein A2 protein.
