The Human Body Is A Marvelous Thing

I don't trust the medical community all that much unless I have a broken bone or some such thing. Every day I see something claiming this is good for you or that is bad for you and it's now at the point where I don't know what to believe.
Take calcium supplements, for example. For years and years women have been urged to take calcium supplements to stave off osteoporosis. Sounds reasonable enough. The thing is, taking additional calcium *might* keep you from developing osteoporosis, but it might also just kill you from a heart attack!
What researchers found should make supplement-poppers take notice: those who had the highest intake of supplementary calcium — 1400 mg a day or above — had double the risk of dying from any cause and a higher risk of dying from cardiovascular disease than those whose intake was a more moderate 600-1000 mg a day.
It's not completely clear what the relationship is between calcium supplements and heart disease, says Dr. Orli Etingin, professor of clinical medicine and director of the Iris Cantor Women's Health Center at New York-Presbyterian Hospital.
"We have no idea what it is about calcium that's bad for the heart," she says. "The plaque found in coronary arteries is calcified, so one might guess it has something to do with the calcification of plaque. But much of that relationship remains to be determined, if in fact it holds true."
For your own health, you really need to start reading labels and keeping a food diary. I use Fit Day and it seems to work well enough for me. I'm sure there are many others out there. One of the problems with supplements is people don't know how much calcium they are consuming in their food, so they don't know exactly how much of a supplement they need.
They call it *supplement* for a reason!
