Guest guest Posted September 16, 2004 Report Share Posted September 16, 2004 > The August 16th issue of Science News has an article about pregnant women and calcium. Apparently, in most women, their bones start breaking down at about 3 months of pregnancy, presumably to provide calcium for the growing baby. This also releases lead from the bones into the blood where it is absorbed by the baby. In this test, they took 20 women and gave them calcium supplements daily, and also gave them a high calcium diet. (The article didn't say if they also supplemented magnesium, D, etc.). For those women, the bone breakdown started happening later, at about 6 months of pregnancy. Unfortunately, the article isn't online unless you subscribe ... but you can probably get it from the library. Anyway, I thought this was interesting for a couple of reasons: 1. If you are pregnant, be sure to get lots of calcium!!!!! 2. Even plain ol' calcium supplements seem to help. Also, I can't think it is normal human functioning to break down the bones at any time ... I'd guess that our ancestors ate a LOT more calcium than those women were getting (or they had more Vit D, K, Magnesium, etc.). The article also mentioned that lead has the same kind of atomic structure as calcium, so it gets stored where calcium gets stored (hence it gets into the bones). If lead is stored in the bones then this could be an issue for eating fermented bones too ... we don't really have a good way of knowing how much lead a cow gets (presumably most grass fields don't have high lead content, unless someone dumped something there or it is upwind of a freeway?).
