You bring up a good topic that I have thought about for quite some time.
From my research and self experimentation on healthy eating I have come to find it is very important to keep an equal calcium to phosphorous ration.
Meat is high in phosphorus.
Milk just has an idea calcium ration and is easy to obtain.
Egg shell powder and oyster shell powder have gotten good reviews because it has the right kind of calcium.
Native Americans were known to eat bone powder and high calcium greens with all of there meat.

A part of me feels that milk is not the ideal food to consume it is almost out of convenience rather than optimal health.
I am considering experimenting with eating bone powder or egg shell powder or oyster shell powder with my meat at some point and giving up the majority of my dairy.
