Why Casein (a Protein In Dairy) is a Problem
In 1981, scientists found a substance in dairy products that looked remarkably like morphine. After a complex series of tests, they determined that, surprisingly enough, it actually was morphine. By a fluke of nature, the enzymes that produce opiates are not confined to poppies — they also hide inside cows’ livers. So traces of morphine can pass into the animal’s bloodstream and end up in milk and milk products. The amounts are small and the discovery led scientists on their search for opiate compounds in dairy products.
And they found them. Opiates hide inside casein, the main dairy protein. As casein molecules are digested, they break apart to release tiny opiate molecules, called casomorphins. One of these compounds has about one-tenth the opiate strength of morphine. Scientists are now trying to tease out whether these opiate molecules work strictly within the digestive tract or whether they pass into the bloodstream and reach the brain directly.
It is the opiate effect that is one of the main problems in those with food intolerances, especially those prone to constipation, as it is the opiates that cause constipation, normal milk contains A1 beta-casein which appears to be the problem, as it causes the creation of opiates, whereas A2 beta-casein appears not to cause the creation of opiates. This is why we trial a2 milk at first in those people that test positive for dairy in the food intolerance test, and on most occasions the replacement of normal milk with a2 seems to ease the problem – except clinically it does not seem to be as successful for those that suffer from diarrhoea as a main symptom.
Animals that produce A1 beta-caseins are Holstein cows, the majority of all milk and dairy products on the market are made from Holstein cows, as is A1, A2 is from goat, sheep, buffalo, and a majority jersey and gernsey cow milk is A2.
You all know my take on dairy food- COWS MILK IS FOR BABY COWS- however I have seen some great success stories with food intolerance clients that are able to and do use a2 milk and yoghurt as well as dairy products from A2 animals as above
