OSTEOPOROSIS: CALCIUM FACTOR

‘Drink up your milk.’ Probably the first health ‘fact’ we arc ever told is that calcium-rich foods are good for our bones and teeth. Nowadays the message is that calcium-rich foods, or calcium supplements, will help prevent osteoporosis. Well, up to a point, Ninety-nine per cent of the body’s calcium is certainly stored in our bones. Bone is a living, hard yet flexible tissue made up of small crystals of calcium, phosphorus and other minerals held together by collagen. The crystals give our bones strength. The bones need constant supplies of calcium for renewal. But there is more to it than that. What puts calcium into bones and what takes it out We may be taking in sufficient calcium but not enough is necessarily being deposited in our bones. Too much may be excreted in our urine. We must indeed replenish our calcium suppliesbut we must also make sure we are not depleting our stores of calcium unnecessarily at the same time. It’s one thing putting calcium-rich food in our mouths; getting it into our bones is a different matter, and one that is all too frequently glossed over by snappy headlines and the glib advice dished out to women. There is a lot more involved in the process.
When we eat food containing calcium, we need both stomach acid (hydrochloric acid) and vitamin D in order to absorb that calcium properly. The calcium is incorporated in our bones by the action of a hormone, calcitonin. If our blood levels of calcium drop, another substance, parathyroid hormone, reabsorbs calcium from our bones and circulates it in the blood to right the imbalance. So this process is dependent on two opposite-acting hormones, calcitonin and parathyroid hormone, which keep our blood calcium in balance. If there is insufficient calcitonin, not enough calcium can be deposited in our bones. If there is excess parathyroid hormone, too much calcium can be taken out. Oestrogen stops the latter hormone going about its business of taking calcium from bone to rebalance the amount in the blood. This is one reason why women are constantly told that the oestrogen in HRT provides protection against osteoporosis. In a narrow sense this is true. But it does not address the fundamental issue of maintaining the all-important calcium balance.
The key to healthy bones lies in maintaining this delicate calcium balance and here our diet is absolutely crucial.

Functions of the bone hormones
Calcitonin
Production is stimulated by high calcium and magnesium in the blood. It:
acts on osteoblasts (builds new bones),
decreases blood calcium levels,
stops release of calcium from the bones.

Parathyroid
Production is stimulated by low calcium and magnesium in the blood. Oestrogen stops its production. It:
acts on osteoclasts (dissolves old bone),
increases blood calcium levels,
triggers the release of calcium from the bones,
oestrogen stops its production.
