A couple of my favorite things from this study:
"3. What are the additional benefits of milk fresh from the cow?
Milk fresh from the cow is a complete, living, functional food. Although we have looked at the numerous nutritional components of milk in the previous two questions, the full benefits of milk are only realized when all of these components function as a complex interdependent and balanced process.
Proteins are incrementally denatured by heat. With lower heat treatment levels, complex proteins with three-dimensional configuration are altered. With higher heat treatment levels, the primary shape and bonds are altered. At very high heat levels, there are destructive chemical changes.and...
This is complex because changes to the fat globules, specifically the membranes, are caused by both heat and homogenization. Of all the milk constituents, the milk fat globule is the most drastically altered by the combination of pasteurization and homogenization.
The emphasis above is mine. I strongly recommend you spend a little time reading this wonderful information.
Best of Health to you
