This is interesting and thanks for the information.

I believe it's also important to be aware that the issues with calcium come from the source.

I heard a study at a seminar in Utah a few years ago that new research found that when calcium is pasteurized, the calcium will not deposit properly and cause spurs and numerous other problems. According to this study, Doctors that stopped their patients from taking dairy had spurs and osteoporosis "go away" when they supplemented with an organic source of calcium and magnesium.

The implications of this are huge because the dairy industry and many other products like breakfast cereals and orange juice have this inorganic or pasteurized calcium.
