Well using Oprah to discredit anything is appropriate but the fact is that Calcium is an essential element, essential meaning the body must have it and since the body cannot produce calcium itself it must come from and outside source!
I agree also that the doctor is not being up front with us
by not including more information ,since he was speaking as an authority and makes no distinction between milk products from commercially toxic dairy cows and raw milk from healthy grain fed milk cows, which is well known for its nutritional value.
Fact is the use of some commercial foods is the reason we need supplementation! If you can't get it from your food you must supply it somehow!
