Please understand that I do not recommend drinking pasteurized milk of any kind – ever. Because once milk has been pasteurized it’s more or less “dead,” and offers little in terms of real nutritional value to anyone, whether you show signs of intolerance to the milk or not.
Valuable enzymes are destroyed, vitamins (such as A, C, B6 and B12) are diminished, fragile milk proteins are radically transformed from health-nurturing to unnatural amino acid configurations that can actually worsen your health. Finally the eradication of beneficial bacteria through the pasteurization process actually ends up promoting pathogens.
The healthy alternative to pasteurized milk is raw milk, which is an outstanding source of nutrients including beneficial bacteria such as lactobacillus acidophilus, vitamins and enzymes, and it is, in my estimation, one of the finest sources of calcium available.
Raw milk is generally not associated with the health problems linked to pasteurized milk, and even people who have been allergic to pasteurized milk for many years can typically tolerate and even thrive on raw milk.
However, some people may still experience problems, such as upper respiratory congestion, when drinking raw milk, and the difference between the breeds of cows the milk comes from appears to hold the answer.
Different Cows = Different Milk
This is an issue you may never have heard of unless you’re familiar with the bovine industry, or have done a fair amount of research on milk. But there are actually distinct differences in the milk produced by various breeds of dairy cows.
So-called A1 cows are “newer” breeds that experienced a mutation of a particular amino acid some 5,000 years ago, whereas A2 cows are the older breeds that do not have this mutation.
As Thomas Cowan, MD, a founding board member of the Weston A. Price Foundation explains in his article “Devil in the Milk,” milk consists of three parts:
- Milk solids
The milk solids consist of a variety of proteins, lactose and other sugars. One of these proteins is called beta-casein, and this is the protein of interest when comparing A1 and A2 milk.
All proteins are long chains of amino acids. Beta casein is a chain of 229 amino acids. A2 cows produce this protein with a proline at number 67, whereas A1 cows have a mutated proline amino acid, which converts it to histidine.
