2. The milk is pasteurized. Pasteurization is the process of heating a liquid to a high enough temperature to kill certain bacteria and disable certain enzymes. It destroys enzymes, vitamins, denatures fragile milk proteins, kills beneficial bacteria and promotes pathogens. Even calves fed pasteurized milk do poorly and many die before maturity. Pasteurization was instituted in the 1920s to combat TB, infant diarrhea, undulant fever and other diseases caused by poor animal nutrition and dirty production methods. But times have changed and modern stainless steel tanks, milking machines, refrigerated trucks and inspection methods make pasteurization absolutely unnecessary for public protection.
3. In some cases, milk is ultra-pasteurized to get rid of heat-resistant bacteria and give it a longer shelf life. Ultra high temperature pasteurization is a process that takes milk from a chilled temperature to above the boiling point in less than two seconds. This process is utilized for the boxed milks that can be kept at room temperature
4. To make matters worse, milk is homogenized. Homogenization is a process that breaks down butterfat globules so they do not rise to the top. Homogenized milk is harder to digest, so proteins that would normally be digested in the stomach are not broken down and instead are absorbed into the bloodstream. Often the body reacts to these “foreign proteins” by triggering the immune system, causing inflammation. It can even trigger auto-immune problems. Homogenized milk has also been linked to heart disease probably because of the fat globules that are dispersed by the process.
