When milk is passed through a fine filter at pressures equal to 4,000 pounds per square inch, the fat globules (liposomes) are made smaller (micronized) by a factor of 10 times or more. These fat molecules become evenly dispersed within the liquid milk.

Milk is a hormonal delivery system. With homogenization, milk becomes a very powerful and efficient way of bypassing normal digestive processes and delivering steroid and protein hormones to the human body. Homogenization is technology's way of improving upon nature's mechanism.

Through homogenization, fat molecules in milk become smaller and become "capsules" for substances that bypass digestion. Proteins would normally be digested in the stomach or gut. By homogenizing milk, these proteins are not broken down and are absorbed into the bloodstream, intact.

Two Connecticut heart researchers, Oster and Ross, demonstrated that cow proteins survive digestion. Their heart patients developed antibodies to bovine proteins after consuming homogenized milk. This proved that milk proteins are not destroyed by digestion. Hormones in milk are protected, survive digestion, and exert powerful effects on the human body.

The scientific community believes that the survival of protein hormones after ingestion is not possible because of the strength of stomach acid and enzymatic activity. Oster and Ross pointed a finger of blame at the homogenization process. They discovered the presence of an enzyme, bovine xanthene oxidase (XO), which, in theory, should not have survived digestion. The XO Factor was identified as the element that destroyed one-third of the cellular material in atrial cells of 300 heart attack victims during a five-year study.

"Bovine milk is presently under investigation by this laboratory since it has been shown that milk antibodies are significantly elevated in the blood of male patients with heart disease."

"Bovine milk xanthene oxidase (BMXO) may be absorbed and may enter the cardiovascular system. People with clinical signs of atherosclerosis have greater quantities of BMXO antibodies. BMXO antibodies are found in greater quantities in those patients who consume the largest volumes of homogenized milk and milk products."

"Atherosclerotic patients exhibit an immune response to bovine xanthene oxidase."

American Laboratory, August 1974

"This study conclusively demonstrates that XO from cow's milk does get into the bloodstream. Seventy-three out of the 94 people tested (of all ages) had antibodies to XO."
