A LITTLE INFORMATION ABOUT RAW MILK
Raw Milk contains every known fat and-soluble vitamin in its whole, bioavailable forms. Again, raw milk contains every known essential mineral, but the major parties are calcium, magnesium, phosphorous, sodium, and sulfur. It even has 24 vital trace minerals. And you guessed it -all are 100% bioavailable! All 60 (known) enzymes are found intact and fully functioning in raw milk. Some come from the milk itself, while others come from the beneficial bacteria that grow in milk. They have many functions, but they help digest milk while freeing up key minerals for us to use. Some even protect milk from unwanted pathogens, making it safer to drink! Once pasteurized, fewer than 10% of enzymes remain! Raw milk contains all 22 amino acids (the building blocks of proteins), including eight essentials. All are 100% available.
Pasteurized milk is dead milk. The heating process kills the lactase, making it impossible to digest lactose (most people aren't lactose intolerant), and kills many beneficial bacteria, enzymes, and nutrients. Heat changes everything. Some vitamins are hit harder than others, but it's estimated that only 50% of vitamin value remains active in milk after pasteurization. Fat-soluble vitamins (A, D, E & K) are especially unstable, particularly when heated above body temperature. This loss can exceed 66%! Water soluble vitamins vary and range from 38% to an 80% loss. Vitamin C exceeds 50%! While minerals are inorganic and cannot be killed by heat, they are altered dramatically. Calcium, one of the most essential minerals necessary for cellular function, loses as much as 50% potency.
But isn't milk fortified with vitamins and minerals?
Yes, it is, but that makes no difference. Synthetic forms of vitamins aren't easily broken down and used by the body. In nature, vitamins never occur in isolation but in a complex network of synergistic vitamins, minerals, enzymes, and cofactors that are necessary for recognition and use by the body. You dont get this with lab-made vitamins and minerals.
