Calcium and Death Rate
The magazine Health After 50 reported on the Iowa Women's Health Study.
Experts used a questionnaire to collect data from 39,000 women 55-69 years old concerning their dietary supplements.
After 19 years they looked at death rates. Many of the supplements were associated with a higher risk of death.
However, the consumption of calcium was associated with a lower death rate.
Does this study show that consumption of calcium causes lower death rates?
