Dr. Heaney compares the calcium in fortified beverages to the calcium found in milk.
The calcium in milk compares to the calcium-fortified vegetables simply in its company. The calcium in milk comes in with phosphorus and protein and vitamin D and potassium and magnesium, and the calcium in the calcium-fortified vegetables comes in basically with none of those, maybe one or two, but certainly not protein and protein is absolutely essential for bone health.
Calcium has been shown not to work at all in women who don’t have an adequate protein intake and the reason is, you can’t make bone out of just mineral. You have to make bone out of a protein matrix, the form into which the mineral is deposited. So you need both and you don’t get that with a calcium-fortified beverage.
